By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW.

Version 0.9.0.3, 2009-Mar-31 + + o Revise --version to include ImageMagick library information. + o Add ditz issue database and package document BUG-REPORTING. + o Refine warnings for 8-bit output when --16bpc (incl. default). + o Fix --16bpc default behavior. + o Fixed serious memory leak in alignment code, and less serious leaks. + +45. Version 0.9.0.2, 2008-Nov-05 + + 45.1. Documentation + + o Update documentation makefile for better links compatibility. + + 45.2. Scripts + + o Fix 'exec -a' bashism in ale script, after this was reported by Mihai + Varzaru as being broken in Ubuntu 8.10. + +44. Version 0.9.0.1, 2008-Jun-13 + + o Use a pager (e.g., less) when displaying help. + o Add a man page, at the recommendation of Debian developer Ruben + Molina. The man page structure roughly follows that of Debian + Iceweasel, GNU tar, and the earlier ALE manual page for Debian by Nick + Rusnov and Ruben Molina. + o Add new algorithms for pixel assignment in multi-alignment, including + filling, least-size local selection, and global-best selection. + o Fix various multi-alignment bugs, including a bug causing increased + computational complexity for rendering, as well as offset and scaling + bugs. + o Modify --lod-max to --lod-preferred, add a dimension restriction + --min-dimension on level-of-detail, and make --lod-preferred=-3 and + --min-dimension=10 default. + o Revise DejaGNU test suite for current option syntax, so that "make + check" now runs all tests. + o Do not attempt to handle --trans-{save,load} arguments as images in + the ale wrapper script. + o Add include to ui/ui.h in an attempt to resolve Debian bug + #482765, reported by Marc Brockschmidt and noted by Ruben Molina. + o Include more information about scale cluster structures in the logging + ui. + o Add tonal registration by element to multi-alignment code. + o Add a minimum average certainty for registration of multi-alignment + elements. + o Modify ale script to tally thread statistics when the environment + variable ALE_COUNT_THREADS is set non-zero. + +43. Version 0.9.0, 2008-Apr-14 + + o Add skeletal web documentation to the documentation tree, in doc/web, + and revise this to consolidate more information on the front page. + o Implement an alignment technique allowing multiple alignments for a + single frame. Handling parts of a frame separately to resolve + alignment issues (but using match thresholding to discard regions + instead of using multiple alignments) was suggested by Rob Stewart. + o Add --resident parameter, allowing explicit allocation of backing + store for (e.g., large) image data structures. + o Check for NaN in linearization and unlinearization in + exposure_default, as a possible fix for a segmentation fault reported + by Bret Towe. + +42. Version 0.8.11, 2007-Nov-03 + + o Revise certain code for improved execution speed, including disabling + certain assertions and reducing calls to pow(). + o Replace geometric-mean filtering of weight values with minimum-value + filtering, reducing calls to pow(). + o Add fixed-point data types selectable at configuration time for + coordinate and color data, hence improving speed on certain embedded + platforms. Use on phones was suggested by Wen Guihua. + o Revise incremental rendering code to store color values unnormalized + by weights. + o Revise multi-alignment options for the currently-considered + implementation. + o Eliminate NaN propagation that could lead to alignment failure in + certain cases, perhaps causing an alignment bug reported in earlier + versions by Gregory Maxwell. + +41. Version 0.8.10.1, 2007-Oct-04 + + o Change 'char *' referencing string literals to 'const char *'. + o Set perturbation multipliers to 1 in cases of a non-finite value. + +40. Version 0.8.10, 2007-Oct-02 + + o Add threading for d2::image::*scale_by_half() functions. + o Always rescale transformations for full detail after alignment is + complete. + o Make --lod-max=-4 default. + o Make default --dchain auto:triangle:2,fine:box:1,triangle:2, which + should produce better output during re-filtering than the previous + default. + o Revise re-filtering operation to use as a filter scale the distance + between nearest defined points in opposite axis-centered cones about + the point to be filtered. + o Update scale cluster structures and interpolation routines used in + alignment for calculating and storing certainty and weights; in + particular, certainty of the input frame is now pre-calculated for + multiple levels of detail. + o Add currently-unused skeletal code for non-linear level of detail + calculations. + o Revise Monte-carlo value to use a single static default, removing + dynamic behavior and certain associated support code, and applying the + sampling rate in a uniform manner to all levels of detail and all + tonal and spatial registration algorithms. + o Fix error in level-of-detail accounting in alignment code. + o Replace references to math.h with references to ale_math.h. + +39. Version 0.8.9.1, 2007-Aug-31 + + o Attempt to resolve certain 'always true' warnings reported by Marius + Schamschula on Mac OS 10.3.9 (PPC). + o Add macros for isinf() and isnan() in an attempt to resolve build + failures reported by Marius Schamschula on Mac OS 10.3.9 (PPC). + o Resolve certain build errors occuring when configuring + --disable-threads, or when threads are unavailable. + o Remove instrumentation writing to 'lsimulated.png'. + +38. Version 0.8.9, 2007-Aug-25 + + o Set new defaults for --ips, --dchain, and --3d-dchain, and remove --q* + o Add rendering chain scaled sampling filter type auto:, implementing + re-filtering, with rough automatic filter size determination. + o Add an abstract domain decomposition threading class. + o Revise Irani-Peleg code for reduced memory and cpu use. + o Attempt to fix exclusion region handling after a bug report by Gregory + Maxwell; other issues may remain. + o Fix handling of --ip-{mean,median}, resolving a bug noted by Gregory + Maxwell. + o Add wrapper script 'ale' for handling raw files and extracting Exif + metadata. + o Allow any match when the threshold specified is neither positive nor + zero. + o Update license to GPLv3. + o Various rendering bugfixes. + +37. Version 0.8.8.1, 2007-May-18 + + 37.1. Build + + o Disable d2::gauss::cutoff definition after a build failure reported by + Marius Schamschula on an Intel Mac running 10.4.9 (gcc 4.0.0?). + +36. Version 0.8.8, 2007-May-15 + + o Include an incomplete implementation for multiple alignment region + handling. + o Make --16bpc default. + o Add extents calculation to d2::render::ipc to limit the area examined + during exposure re-estimation. + o Provide a new cache of fixed size for input images, defaulting to + 256MB, adjustable via the --cache option. + o Add error statistics for calculating center of rotation and + perturbation size for alignment. + o Add loop avoidance for dynamic monte carlo alignment. + o Reduce --mcd-removal default to 10. + o Use synchronized instead of unsynchronized dynamic monte carlo removal + checks. + o Disable --follow in the non-default case when perturbation size is + zero. + o Make --no-inc default. + o Add 'defaults' global search option, and make this option default. + o Modify --gs-mo to allow specification as a percentage, and make 67% + default. + o Add user interface options --ui=log and --ui=quiet, with greater and + lesser verbosity, respectively. + o Modify black level handling to always use linear values. + o Increase default barrel distortion multiplier and rate maximum to 2.0 + and 8.0, respectively. + o Revise ordering of ui_tty status output so that more informative + fields occur earlier in the string. + o Modify numerical formatting of certain UI elements to preserve + constancy of field locations in typical cases. + o Add Gaussian PSF. (HJ Hornbeck) + o Recalculate diff statistics after increasing the mc parameter in + dynamic monte carlo alignment. + o Update Nikon D50 PSF. (HJ Hornbeck) + o Add UI update thread, in cases where threads are available. + o Allow file-scoped --gs and --gs-mo options. + o Ignore fex regions for nex SSFEs, resolving a bug noted by Gregory + Maxwell. + o Add --black option for specifying black level as a fraction of + saturation. + o Add --ev option for specifying ISO100-equivalent EV. + o Add breakdown of profiling information by perturbation size for local + alignment. + +35. Version 0.8.7, 2007-Mar-04 + + 35.1. Alignment + + o Modify d2::image::defined_scale_by_half() to use a geometric mean, so + that alignment at reduced level of detail will still work at larger + reductions when using non-zero certainty. + + 35.2. Rendering + + o Add a weight-limiting option to the Irani-Peleg renderer. + o Add incremental renderer mean invariant avgf:: weight-limited to + initial values. + +34. Version 0.8.6, 2007-Feb-17 + + o In d2::align, use rotation about the frame center as an alternative in + cases where the sampling centroid is undefined. + o Modify d2::point::{neg,pos}inf() assertions to allow for isinf() + implementations returning any non-zero value for any infinity. + o Re-adjust exposure in Irani-Peleg even when no non-linear stage is + present. + o Adjust the default pixel definition threshold to account for the + certainty floor. + o Use a rudimentary, single-pass estimate-based certainty approach for + incremental rendering. + o When --cx is positive, use only certainty calculated from the + simulated scene for estimating tonal registration in Irani-Peleg + passes. + o Remove --qr default setting, as certainty and range-extension now have + established general defaults. + o Change --cx to 1 by default. Change --exp-extend to be disabled by + default. Remove these flags from default settings. + o Update driver names to omit file type qualifiers, according to the + convention used in HJ Hornbeck's Nikon D50 device configuration patch. + o Add Nikon D50 device configuration. (HJ Hornbeck) + o Update default settings according to time and image quality test + results. fine:triangle:2, gauss:0.75, and combinations of these + filters were suggested by HJ Hornbeck. + o Revise incremental renderer to store unnormalized values, for better + handling of small weights, and eliminate the minimum contribution + weight. + o Add inlining and pre-calculation to Irani-Peleg. (HJ Hornbeck) + o Add gaussian sampling filter. (HJ Hornbeck) + +33. Version 0.8.5, 2007-Jan-19 + + 33.1. Documentation + + o Remove binaries and documentation sections from the readme, and prune + non-package documentation for source distributions. + + 33.2. Alignment + + o Make the --follow alignment option default. + o Modify rotational alignment search to rotate about the centroid of the + sample region. + + 33.3. User interfaces + + o Add help text for argument scope. + + 33.4. 3D Models + + o Revert 3D code to experimental status due to poor handling of real + image sets. + o Modify 3D code for slightly better handling of real image sets. + +32. Version 0.8.5-pre3, 2006-Nov-03 + + 32.1. Alignment + + o Fix a potential nondeterminism bug due to undefined seed bits in the + random number generator. (Fixes certain alignment failures.) + o Add dynamic monte carlo alignment, and make this default. + o Allow file-scoped use of --perturb-upper. + + 32.2. Rendering + + o Modify default settings using Irani-Peleg rendering to use the + triangle:2 incremental rendering chain. + + 32.3. Exposure + + o Correct --exp-mult arg count. (Gregory Maxwell) + +31. Version 0.8.5-pre2, 2006-Oct-25 + + 31.1. Alignment + + o Add option --profile to measure elapsed real time for 2D alignment and + rendering operations. + o Add support for POSIX threads to 2D alignment and rendering code. + (Adding multithreading support was first suggested by Jody (Joe) + Harris. Testing of multithreaded code on multiprocessor hardware was + done by Gregory Maxwell.) + + 31.2. Rendering + + 31.2.1. Scale + + o Modify d2::image::scale() to correctly handle offsets for scale + factors other than negative powers of two. + + 31.3. User interfaces + + o Reformat most help text to fit a 79 column screen. + +30. Version 0.8.5-pre1, 2006-Oct-16 + + o Incorporate all existing ALE documentation within the source tree, and + license under GPL. Begin migration of documentation, including package + documentation files, to a more flexible format. + o Modify ui_tty for correct operation under Hurd and DragonFly consoles. + o Revise README for autotools build and installation. + o Add file 'TODO', containing a to-do list for future releases. + o Add AUTHORS file, in accordance with the autotools packaging + standards. + o Revise Changelog name to autotools-approved ChangeLog + o Add NEWS file containing mailing list and Freshmeat announcement text + for versions through 0.8.4. This file is required by autotools. + o Add options --f{ex,crop} for frame-coordinate exclusion regions. + o Add autotools-based configuration, build, and installation facilities, + replacing the earlier Makefile-based configuration and build process. + o Modify --mc to be a file-scoped option. + o Modify command-line interface to accept certain scope operators, and + to increase uniformity of syntax. + o Move input interface details, including option handling, messages, and + help information, to the ui/ subdirectory. + o In d3::scene, always use filler spaces when --pc all is specified. + +29. Version 0.8.4, 2006-May-14 + + 29.1. Packaging + + o Fix build error noted by Gregory Maxwell and re-tag version. + + 29.2. Documentation + + o Add dates to the Changelog, using dates in comments in the download + page on the website for versions prior to 0.8.0, and using dates from + the darcs repository for versions 0.8.0 and later. + + 29.3. Alignment + + o Add a script 'transform' for applying an inverse projective + transformation. Recalculation of transformations was suggested by Rob + Stewart (ALE mailing list message, 2005-Dec-28). + + 29.4. Rendering + + o Move low-level code concerning scale and level-of-detail from + d3::scene to d3::pt. + o Remove older 3D rendering code. + o Add decimation options --di-upper, --di-lower, and --do-try for + reducing the complexity of 3D scene geometry, hence reducing the + number of operations required for occupancy updating. + + 29.5. Filtering + + o Add support for filtering 3D output with --3d-filter. This is now the + default behavior. Add an option --3d-chain for selecting the filter + chain used for 3D output. (See --hl and --hq for details.) + + 29.6. User interfaces + + o Add fine-grain UI updates for 3D operations when using ui=tty. Reduce + tty UI status update frequency to at most once per second. + + 29.7. 3D Models + + 29.7.1. Rendering + + o Add support for synthetic focus via the --focus option, including + focus with horizontal and vertical tilt. Adding simulated focus + effects, including tilted and swung focal planes, was suggested by + Gregory Maxwell. + o Interpolate to generate smooth 3D depth output. + + 29.7.2. Geometry + + o Modify --3dpx to affect scene geometry rather than rendered pixels. In + certain cases, this change should allow removal of objects close to + the camera, hence revealing objects further away. + o Fix dimension comparison bug in d3::space::traverse::get_next_split(). + o Implement an experimental approach to 3D subspace candidate selection; + this seems to perform poorly in most cases due to parallax effects. + See the source code for details. (Option --subspace-traverse) + o Move code concerning the nature of space from d3::scene to d3::space. + + 29.7.3. Occupancy + + o Add adaptive weight decomposition to 3D occupancy algorithms. + + 29.8. Undocumented build options + + o Add to the Makefile a HASH_MAP option that can be used to assign the + 3D spatial info structure a hash map type instead of the standard STL + map type. As this is likely to break things, it is currently + undocumented. HASH_MAP=GNU seems to compile with g++ 4.0.x but has not + otherwise been tested. + +28. Version 0.8.3, 2005-Dec-23 + + 28.1. Image files + + o Add an option --def-nn to allow definition of pixels in output images + to take values from neighboring pixels within a certain radius, in + cases where they would not otherwise be defined. + + 28.2. Rendering + + o Add option --3dpx to specify 3D regions to exclude during final + rendering, using a single depth for each pixel in each frame of + rendered output. (Evaluates at the depth used in depth-rendering.) + + 28.3. 3D Models + + 28.3.1. Stereoscopy + + o Add option --pc to specify which pairwise comparisons should be + performed. + o Add option --pa to set the number of point candidates accepted for + each pair of cameras (pairwise ambiguity). The default of 3 preserves + existing default behavior. + o Add option --tcem for scoring point candidates by third-camera views. + The default of 0 preserves existing default behavior. + + 28.3.2. Geometry + + o Add --et option to specify encounter thresholds. + o Clean up d3::scene to remove triangle-mesh code. + o Modify representation of 3D subspaces so that refined subspaces are + roughly cubical, and to allow refinements at multiple resolutions. + + 28.3.3. Occupancy + + o Fix bugs in 3D color and occupancy updating caused by bounding box + miscalculation. + o Add option --oui for determining occupancy update iterations. The new + default is 10, halving the previous default of 20. + +27. Version 0.8.2, 2005-Nov-22 + + 27.1. Command line interface + + o Add magical file 'dump:' for listing color values numerically to + stderr. + + 27.2. Control points + + o Fix various bugs in control-point alignment reported by Gregory + Maxwell. + + 27.3. 3D Models + + o Transition from a subdivisible triangle model to a subdivisible space + model, using a rudimentary implementation of Hans Moravec's notion of + occupancy. + o Add support for view and depth output from arbitrary cameras. + o Add clipping plane options for 3D modeling. + +26. Version 0.8.1, 2005-May-6 + + 26.1. Build + + o Fix enumerator compile bugs noted by Gregory Maxwell and Tom Holroyd + to cause compilation failure under GCC 3.4. + + 26.2. Defaults + + o Modify --q1 to use median-value incremental rendering. + + 26.3. Exposure + + o Add a color adjustment option --exp-mult=. + + 26.4. Transformation data files + + o Add average magnitude comments to transformation data file output. + + 26.5. Control points + + o Add support for using control points in 2D and 3D alignment, as well + as in 3D model construction. New options include '--gs points', + '--cpf-load=', '--cpp-upper=', '--cpp-lower=', '--va-upper=', and + '--st'. + + 26.6. User interfaces + + o Add support for median-value incremental and Irani-Peleg rendering. + Using a statistic other than the mean was suggested by Scott Scriven + as a means of eliminating non-uniform artifacts. Using the median + seems to improve performance on Scott Scriven's example sequences, as + well as on the scaled output of fine:sinc*lanc for sparse inputs. + + 26.7. 3D Models + + o For 3D scene reconstruction, use a new unified surface model in place + of the depth-based multi-model approach used in 0.8.0. The new model + is adjusted on the basis of edge, angle, and color measures. + + 26.8. Source code organization + + o Move ale-psf-calibrate to a new scripts directory. + +25. Version 0.8.0, 2005-Jan-12 + + 25.1. Image files + + o Add support for PPM with extended attributes (EPPM). Attributes + handled specially include black level, shutter speed, aperture, and + ISO (or gain). + + 25.2. Exclusion regions + + o Set image offsets in d2/render/combine.h. This allows Irani-Peleg + rendering to work with --crop when the default rendering chain + includes more than one rendering invariant. + o Replace functions d2::incremental::{increase,decrease}_extents() with + new functions that take exclusion regions into account. The new + functions should also fix a boundary-calculation bug reported by + Gregory Maxwell. + o Modify d2/render/ipc.h to handle exclusion regions more effectively. + o Add --crop argument, which excludes the spatial complement of a + specified area over a specified set of frames. Gregory Maxwell notes + several advantages of internal over external crops, including + preserving knowledge of position in the uncropped frame, which among + other benefits allows natural handling of Bayer patterns. + o Modify rx_parameters in d2/render.h to use the ale_pos data type + instead of int. This should allow exclusion regions to be calculated + more accurately. + + 25.3. Alignment + + o Modify euclidean alignment so that perturb-upper and perturb-lower + apply to rotational arclength. + o Modify d2::align to use unscaled input images when the scale factor is + larger than 1.0, or when a scaled_filter interpolant is being used. + o Modify d2::align::set_exposure_ratio() so that alignment weights and + certainty values are taken into consideration. + o Add a --cw option to weight alignment error by certainty values, as + suggested by Gregory Maxwell. This allows the contributions of pixels + at maxval to be diminished, which can increase alignment success in + certain cases. + + 25.4. Rendering + + o Perform Irani-Peleg updating separately by channel instead of using + vector operations. This allows divide-by-zero and other conditions to + be localized to particular channels. + o Modify the Irani-Peleg renderer to use estimate-based certainty. This + seems to improve noise characteristics significantly. + o Modify d2::render::ipc::_ip_frame_correct() so that exposure + re-estimation uses a ratio of weighted sums instead of a weighted + average of ratios. + + 25.5. Exposure + + o Add a flag --exp-meta-only which causes tonal registration to be + performed only on the basis of exposure metadata (e.g., data encoded + as EPPM extended attributes). This approach was suggested by Gregory + Maxwell. + o Write the results of tonal registration as a comment in the + transformation data file. + o Fix an index variable bug in d2::image_bayer_ale_real::trigger(). + o Modify d2::exposure one-sided certainty so that the 'one-sided' + condition only applies to bright (>50%) areas. Applying it to dark + areas has no clear benefit, and an experiment by Gregory Maxwell + demonstrates that doing so can exacerbate noise. + + 25.6. User interfaces + + o Modify d2::image::scale() to allow scale factors in the interval (0, + 1), and modify the command-line interface and help text to reflect + this change. --scale= now accepts all finite positive values. + o Add user interface options --ui=stream and --ui=tty. The latter + includes more detailed status output when terminal width information + can be obtained (esp. when IOCTL=1 is set at compile time), and is the + new default. + + 25.7. 3D Models + + o Add experimental cost calculation routines to d3/scene.h. + + 25.8. Source code organization + + o Move certain user interface elements to the source subdirectory ui/. + +24. Version 0.7.3, 2004-Dec-1 + + 24.1. Build + + o Implement optimizations that reduce the memory footprint when 3D + options are used. + o Optionally (when OPTIMIZATIONS == 1) use the output of the default + rendering chain directly as the Irani-Peleg initial approximation, + instead of copying it. + + 24.2. Defaults + + o Add a check to ensure that at most one --q* option is specified. The + issue of multiple --q* options being specified was raised on the ALE + mailing list by Viktors Rotanovs. As there is currently no support for + this, generating an error message is appropriate. + + 24.3. Rendering + + o Add incremental 3D reconstruction output. + o Add support for the Canon 300D with a 50mm f/1.4 lens (specifying view + angle), as well as experimental support for the 50mm f/1.4 lens at 1.4 + (specifying a linear PSF). Also add support for 50mm f/1.8 and 85mm + f/1.8 lenses, specifying view angles as specified in the chart at + http://www.acapixus.dk/photography/angle_of_view.htm + o Move all PSF parsing logic to a new file: d2/render/psf/psf_parse.h + + 24.4. Exposure + + o For cases where --psf-match is specified, modify the exposure settings + for the final input image (i.e., reference image) so that default + exposure is used, and modify the bayer pattern settings so that no + bayer pattern is used. (The first of these modifications requires + changes in the way that the array of input exposures is stored.) + + 24.5. Filtering + + o Don't output final data when --psf-match is specified. Doing so would + be useless anyway, and apparently causes a segfault. + o Add support for PSF convolution and scalar multiplication. + + 24.6. User interfaces + + o Remove the reference to a non-existent web page in + unsupported::fornow(). + o Modify help argument processing so that several help arguments can be + specified at a time. Change the usage text to reflect this. + o Fix concatenated help output; outputs from all help options are now + represented. (3D help had been omitted in 0.7.2.) + + 24.7. 3D Models + + o Allow device-specific bayer patterns to be overridden by the --bayer + option. + o Add an option for explicitly setting the camera view angle. Make the + default view angle 43.7 degrees. + o Modify the 3D cost reduction algorithm. The new algorithm seems to + offer better results than the old in cases tested thus far, and does + not require that spatial extension be enabled. + +23. Version 0.7.2, 2004-Oct-26 + + 23.1. Build + + o Add a rudimentary test suite. (from 0.7.1-patch2) + + 23.2. Command line interface + + o Print version information to stdout instead of stderr. (from + 0.7.1-patch2) + + 23.3. Image files + + o Add rudimentary device support for raw, linear files from the Canon + EOS 300D (Digital Rebel) SLR. CRW files may not be directly usable + under all configurations; in cases where they are not, Dave Coffin's + dcraw program, with arguments -d -4, will produce a raw, linear PPM + file. See http://www.cybercom.net/~dcoffin/dcraw/ + + 23.4. Exclusion regions + + o In render::is_excluded(), add the offset before checking exclusion + regions. (from 0.7.1-patch1) + + 23.5. Alignment + + o Add a new option --gs-mo to establish a minimum overlap area for + global searches. This may allow more of Derrick Brashear's historical + USGS contour map image sets to align successfully. (from 0.7.1-patch2) + o Add support for --perturb-{upper,lower}=x%, where the value x% is + specified as a percentage of the smallest image dimension. Use of + percentages to specify bounds was suggested by Jeff Epler. (from + 0.7.1-patch1) + o Add code to shrink the accumulated image in d2/render/incremental.h, + so that superfluously large undefined areas are never present. This + may improve operation of '--gs inner' in some cases. (from + 0.7.1-patch1) + o In d2::align::_align(), rescale default_initial_alignment in parallel + with the current transformation, so that it can be used again, if + necessary. (from 0.7.1-patch1) + o Add experimental options --perturb-source and --perturb-output, which + allow some refinement of the manner in which perturbation occurs. + (from 0.7.1-patch1) + + 23.6. Rendering + + 23.6.1. Scale + + o Allow the scale factor to be explicitly set to one. (from + 0.7.1-patch2) + + 23.7. 3D Models + + o Add cost-minimizing code to reconstruct 3D scenes from 2D inputs. + (This code is currently very experimental.) + +22. Version 0.7.1, 2004-Aug-27 + + 22.1. Build + + o Add speed optimizations for filtering in the Euclidean case, but leave + these disabled, since they are not safe. (Also included in + 0.7.0-patch1.) + + 22.2. Alignment + + o Add global search option --gs to fix an alignment problem reported by + Bert Douglas. (Also included in 0.7.0-patch1.) + o Change transformation::eu_{get,set,modify}() so that externally + visible values are interpreted in the context of transformations + between scaled images, while internal values represent transformations + between unscaled images. (Bugfix for 0.7.0. Also included in + 0.7.0-patch1.) + o d2/tfile.h: Ensure that eu[] parameters are properly scaled when read + and written. (Bugfix for 0.7.0. Also included in 0.7.0-patch1.) + o Fix order-of-operations bug in d2::image::scale_by_half(). (Bugfix for + 0.7.0 and earlier versions. Also included in 0.7.0-patch1.) + o Scale alignment weights for reduced level-of-detail in d2::align(). + (Also included in 0.7.0-patch1.) + o For reduced level-of-detail alignment reference images, filter using + alignment weights. (Also included in 0.7.0-patch1.) + + 22.3. Rendering + + o Add support for the ov7620 sensor (raw, linear modes only). (Updated + from 0.7.0-patch1 to specify a linear PSF.) + + 22.4. Filtering + + o Add circular point-spread function option "circle=". + + 22.5. User interfaces + + o Add help mode --hA to display all help pages. + + 22.6. Video streams + + o Fix --visp segfault when not using last: filters. + +21. Version 0.7.0, 2004-Aug-06 + + 21.1. Build + + o Add support for algorithmic alignment weights. This requires POSIX + fork() and execlp(), so add a Makefile variable for POSIX. + + 21.2. Command line interface + + o Increment the latest supported transformation file syntax to version + 3. This version supports transformation of the original frame, as well + as other new features described above. + + 21.3. Defaults + + o Add multiple default settings: q0, q1, q2, qn, qr. + + 21.4. Image files + + o In the transformation data file handler, report incompatible + transformation types as an error instead of as a warning. + + 21.5. Exclusion regions + + o Add option --ex, to support exclusion volumes. Region exclusion was + first suggested to the author by Dewayne VanHoozer as a means of + solving the 'closed eye problem' in group photography. + + 21.6. Alignment + + o Add support for frequency-based alignment weights. Angelo Pesce had + initially suggested the related (or more general) idea of edge-based + alignment. Frequencies were chosen because of their conceptual + simplicity. This option requires that FFTW be linked. + o Add support for specifying per-pixel and per-channel alignment weights + by providing an additional weight-map image, as suggested by Bert + Douglas. + o Add options --fail-default and --fail-optimal to select the desired + failure mode. --fail-default uses the default alignment in the case of + failure. + o Add a barrel distortion adjustment multiplier and rate options. + o In d2/transformation.h, add parameters for barrel distortion + correction. In d2/tfile.h, add new barrel distortion command 'B'. The + approach taken is based on that of Helmut Dersch's PanoTools. (i.e., a + polynomial in radial distance is used.) + o Move d2/gpt.h to d2/transformation.h. + o In d2::align, add support for original frame transformations. + o In d2::align::diff() and d2::align::set_exposure_ratio(), treat cases + with and without extension identically. + + 21.7. Rendering + + o Remove support for USM. + o Modify the divisor in d2/render/ipc.h to ensure convergence when using + multiple varieties. + + 21.8. Transformation data files + + o Report unrecognized transformation file commands as errors instead of + warnings. + + 21.9. Control points + + o Add options to control output range. By default, use the range of the + original frame. + + 21.10. Devices + + o Add a device type for the XVP610 camera in 640x480 mode. + + 21.11. User interfaces + + o Partition help into sections, and add a section for transformation + data file help. + o For incremental rendering, add general filtering options. Drizzling + options are no longer supported as such, but the help output offers + examples of how to emulate old drizzling/merging techniques (roughly). + + 21.12. Video streams + + o Add experimental video stabilization options. + + 21.13. 3D Models + + 21.13.1. Rendering + + o Add experimental handling for Bayer patterns. + +20. Version 0.6.0, 2004-Feb-10 + + 20.1. Documentation + + o Update e-mail address information. + o Modify the README to remove information covered in the User Manual. + + 20.2. Build + + o Add command-line options to select plain or raw PNM/PPM formats. + Remove makefile variable PLAIN. + o Add command-line options to select 8/16 bits per channel. Remove + makefile variable BITS. + o Change -Os to -O2 in the Makefile, since -Os no longer achieves + speedup in the most critical codepaths. + + 20.3. Command line interface + + o Convert some operations on pixels and points into vector syntax + through C++ operator overloading. + + 20.4. Rendering + + o In the Irani-Peleg renderer, skip frames that fail to reach the match + threshold. + o Revise the device configuration xvp610_320x240 to use a new filter, + reflecting driver updates (see the relevant web page + http://auricle.dyndns.org/xvp610/ ) and support for non-linear + colorspace point-spread functions. + o In the Irani-Peleg renderer, use a discrete Fourier transform to + ensure that each (point-spread function, backprojection kernel) pair + satisfies condition (9) from theorem 4.1 in the source paper. + o Extend the --replace option to support drizzling. + o Add a polymorphic point-spread function type psf and convert all + external interfaces of ipc.h and usm.h (formerly hf-enhance.h) to use + this type. + o Fix memory leak in d2/render/combine.h:get_image(). (This fix is also + included in a patch for 0.5.1.) + o Modify the USM renderer to write output when incremental output is + enabled. + o In the USM renderer, now only defined pixel values contribute to the + mask. Also, undefined values are no longer masked. + o Modify the Irani-Peleg calibration script into a general point-spread + function calibration script, using a new built-in point-spread + function evaluation module to rate candidates. + o Irani-Peleg and USM (High-frequency enhancement) renderers now use the + same point-spread function configurations. New options --ips, --usm, + --lpsf, --nlpsf, and --device subsume and extend the functionality + provided by options --ip, --ipc, and --hf-enhance. + o Add support for convolutions in non-linear colorspace. This feature is + enabled and configured by the command-line option --nlpsf. (See also + the item above.) + o Linearize channel values within internal data structures so that most + ALE operations are performed on linear data. Steve Mann discusses the + use of linear representations in image processing, e.g. in his paper + http://wearcam.org/comparametrics.pdf . We assume a simple power-law + response by default. + o Modify the image class to use a floating-point data type for storing + pixels. + o Revise identifiers and comments in d2/render/ipc.h to better reflect + the terminology used in the source paper by Irani and Peleg. + o Consoldiate code for computing the position and dimensions of a pixel + in a new coordinate system, and use this new abstraction to reduce the + code size of d2/render/ipc.h and d2/render/drizzle.h (Irani-Peleg and + drizzling code, respectively). + o Change several instances of 'double', 'float', and 'my_real' to + specialized floating-point types 'ale_real', 'ale_pos', 'ale_sreal', + and 'ale_accum'. + o Fix offset calculation in d2/render/ipc.h. This is necessary for + Irani-Peleg rendering of image mosaics extending upwards or to the + left of the original frame. (This fix is also included in a patch for + 0.5.1.) + + 20.5. Exposure + + o Add a generalized, but rudimentary, implementation of Steve Mann's + notion of 'certainty'. For more details, see + http://wearcam.org/comparametrics.pdf + o Add support for exposure registration (i.e., matching of exposure + between different frames). + + 20.6. Filtering + + o Make stdin filter height and width independent of each other. + o Add a point-spread function rasterizer. + o Add command-line support for summation of point-spread functions. + + 20.7. Source code organization + + o Move classes treating snapshots as two-dimensional data to directory + 'd2' and create an associated C++ namespace. We can't use '2d' to + label the namespace, because the C++ grammar won't allow it. + +19. Version 0.5.1, 2003-Nov-19 + + 19.1. Documentation + + o Several of the changes below are based on a suggestion by Bert Douglas + regarding support for 16-bit-per-channel color. See the README for + more information about relevant compilation options. + o Add information to the README regarding new compilation options. + + 19.2. Build + + o Modify the makefile to accept a variable BITS, and differentiate + between values BITS=8 and BITS=16. The latter option causes the macro + BITS_16 to be defined during compilation. + o Add a Makefile option for writing plain (ASCII) PPM files instead of + raw (binary). This option causes the macro PPM_PLAIN to be defined + during compilation. + + 19.3. Image files + + o Modify image_rw.h to handle 16-bit data when BITS_16 is defined. Also, + differentiate between 8-bit and 16-bit ImageMagick builds by checking + MaxRGB. + o In ppm.h, add carriage returns to the set of recognized whitespace + characters. + o Modify ppm.h to read 16-bit binary PPM files (added to the PPM format + spec in April 2000). + o Modify ppm.h to read plain (ASCII) as well as raw (binary) PPM files. + o Modify ppm.h to write plain (ASCII) PPM files when PPM_PLAIN is + defined. + o Modify ppm.h to output 16-bit PPM files when BITS_16 is defined. + o Modify ppm.h to scale input intensity values based on the internal + representation depth (8 or 16 bits per channel). + + 19.4. Exposure + + o Add a file 'channel.h' to describe the color channel data type and + valid range, both being dependent on whether BITS_16 is defined. Use + these generic values, where appropriate, throughout the ALE codebase. + +18. Version 0.5.0, 2003-Nov-02 + + 18.1. Documentation + + o Add more comment documentation to header files. + o Change documentation for --replace. + + 18.2. Image files + + o Emit a more informative error message when the PPM file handler + encounters a file that is not a well-formed PPM binary file. + + 18.3. Alignment + + o Remove certain cloning operations from align.h, but since cursory + tests indicate that scaling with --scale is much more expensive than + cloning, allow cloning to occur when scaling occurs. + o Modify semantics of alignment following by applying to file-loaded + initial transformations a delta transformation D = AB^-1, where B is + the previous frame's (unmodified) initial transformation, A is the + previous frame's final transformation, and ^-1 is the inverse + operator. Using --follow with --trans-load can now improve alignment + success when working with panoramic image mosaics. + o We're not using simulated annealing, so remove comments that claim + otherwise. + + 18.4. Rendering + + o Remove certain unsafe assumptions from ipc/* (now render/ipc/*); this + change includes a modification to ipc.h (now render/ipc.h). Limits of + the rectangle used as an argument to the ::response() function + are now explicitly given rather than implied. + + 18.5. Source code organization + + o Move rendering implementations to subdirectory 'render/'. + +17. Version 0.4.8, 2003-Aug-01 + + 17.1. Alignment + + o Modify Monte Carlo alignment so that the same set of accumulated image + pixels is examined when comparing two transformations. + o Add an option for additional upper-bound constraint of rotational + perturbation. Jeff Epler had noted that the + perturb-upper/perturb-lower options alone may not be suited to working + with sets of higher-resolution images. + o Resolve a bug introduced in version 0.1.1 which had limited rotational + perturbation to 2 degrees. + o Add an option to adjust the maximum level of detail used. The default + maximum is 2/perturb, which matches the default for previous versions + of ALE. + + 17.2. Rendering + + o Modify Irani-Peleg renderer to produce incremental output. + + 17.3. Scripts + + o Modify names of temporary files used in the calibration script. + +16. Version 0.4.7, 2003-Jul-27 + + 16.1. Alignment + + o Irani-Peleg: don't truncate correction values in backprojection. + o Irani-Peleg: don't multiply the weight function by a scale correction + factor in backprojection. + + 16.2. Rendering + + o Irani-Peleg: add support for configurable modules, including a module + that reads its configuration data from standard input and a module + calibrated for an IBM (Xirlink) XVP610 in 320x240 mode. A rudimentary + script for calibrating devices with unknown projection functions has + been included as ipc/ale-calibrate. + o Rename render::operator()() to render::sync(). Update subclasses + accordingly. + + 16.3. Video streams + + o Add a replacement option suggested by Jeff Treece. This option can be + used to facilitate video stabilization. + +15. Version 0.4.6, 2003-Jul-01 + + 15.1. Rendering + + o Allow --ip and --hf-enhance to be used together. [Modify + ip::operator() and hf_filter::operator() so that multiple + post-processing filters can be used.] + o Initialize the drizzled image to be uniformly black. This fixes a bug + introduced in 0.4.2. + o Allocate the correct size image for drizzling. This fixes a bug + introduced in 0.4.5. + +14. Version 0.4.5, 2003-Jun-23 + + 14.1. Command line interface + + o Reduce whitespace in usage() message. + o Modify image file handler interface so that input files are not + scaled. Perform scaling, when necessary, outside of the file handler. + Since unscaled data is needed by the drizzling and Irani-Peleg code, + this fixes bugs in those modules. + + 14.2. Image files + + o Remove call to stat() in image_rw.h. This improves OS independence, + and apparently also allows URL-specification of images when compiled + with ImageMagick support. + + 14.3. Alignment + + o Ensure correct transformation scaling and difference calculation after + alignment is complete, even if alignment terminates with a reduced + level of detail (i.e. perturb-lower > 2). + o Separate the scale() function into two cases: scale() is reserved for + scale factors greater than or equal to one, as in user-specified + scaling; and scale_by_half() is used for the scale factor 0.5, needed + to provide multiple levels of detail in alignment. Modify the + scale_by_half() case to reflect source pixel values more fairly. (This + change affects alignment behavior at reduced levels of detail.) + o Modify align::diff() to use correctly scaled image offset values. + (Bugfix for alignment with --extend.) + o Modify align.h so that the image definition array is correctly scaled + for all levels of detail. (Bugfix for alignment with --extend.) + + 14.4. Rendering + + o Modify image.h to correctly handle image offset values. (Bugfix for + --extend operation.) + +13. Version 0.4.4, 2003-Jun-06 + + 13.1. Image files + + o Specify the binary mode flag to fopen() calls in the PPM file handler. + This change resolves a bug discovered by Benjamin Hill. + + 13.2. Alignment + + o Modify the Monte Carlo pixel selection algorithm so that the expected + number of sampled pixels more closely matches the specified number in + typical cases. + +12. Version 0.4.3, 2003-May-30 + + 12.1. Alignment + + o Add support for Monte Carlo alignment of images, in which only a + random subset of pixels is sampled. + + 12.2. Rendering + + o Add an option to disable incremental image output. + +11. Version 0.4.2, 2003-May-23 + + 11.1. Build + + o Add missing typecast to resolve compile warning under GCC 3.2. + + 11.2. Image files + + o Modify PPM file reader to correctly handle comments in PPM files; this + resolves a bug pointed out by Benjamin Hill. + + 11.3. Alignment + + o Clean up source; move rendering and alignment functions into separate + files. + o Make changes to gpt.h that may reduce the Euclidean alignment time. + + 11.4. Rendering + + o Implement an image reconstruction option based on the work of Irani + and Peleg. + o Change valid drizzling diameter interval to (0,1]. + + 11.5. Source code organization + + o Move ale.c to ale.cc to follow one of the many C++ naming conventions. + +10. Version 0.4.1, 2003-Apr-28 + + 10.1. Documentation + + o Separate into a number of subsections the option descriptions in the + README + o Add URL information to README + + 10.2. Build + + o Change language to C++. + + 10.3. Alignment + + o Add an option to use the previous frame's final transformation as the + default alignment. + o Modify the transformation algorithm to use transformations from the + domain of the input image to the range of the target image. This + change is reflected in transformation files. Maintain support for old + transformation file versions, however. + + 10.4. Rendering + + o Add an experimental drizzling implementation. Research on drizzling by + Richard Hook and Andrew Fruchter was brought to the attention of the + author by Dan Kaminsky. + o Change pixel weight data type so that more than 255 images can be + merged. + o Add support for increased spatial extents. Research on increased + spatial extents by Steve Mann was brought to the attention of the + author by Dan Egnor. + + 10.5. Transformation data files + + o Add version information to transformation files and update the version + from 0 to 2. + + 10.6. Source code organization + + o Code cleanup in ale.c, image.h, and gpt.h. + +9. Version 0.4.0p1, 2003-Apr-04 + + 9.1. Build + + o Merge a bugfix from Debian ALE package version 0.4.0-1. Without this + fix, an assertion failure can occur when ImageMagick support is + enabled. Original fix implemented by Nick Rusnov. + +8. Version 0.4.0, 2003-Mar-30 + + 8.1. Rendering + + 8.1.1. Scale + + o Add support for general scaling parameters (i.e. all scale factors >= + 1.0). --scale2, --scale4, and --scale8 are now deprecated, and + replaced with a more general --scale=x argument. + o Support enhancement of high frequencies even when the scale factor is + 1.0. + o Modify the high-frequency filter function so that the response is now + (4/n)^2 times what it used to be, where n is the scale factor. + + 8.2. Filtering + + o Modify the high-frequency filter algorithm to support filtering near + the border of an image. + +7. Version 0.3.2, 2003-Mar-26 + + 7.1. Filtering + + o Don't filter high frequencies if we're not enhancing them. This + improves efficiency, but should not affect output. + +6. Version 0.3.1, 2003-Mar-25 + + 6.1. Rendering + + o Add support for post-enhancement of high-frequency details. + + 6.2. Transformation data files + + o Update informational output to transformation files to include + original frame. + + 6.3. User interfaces + + o Output average match statistic. + +5. Version 0.3.0, 2003-Jan-17 + + 5.1. Build + + o Modify Makefile to compile with size optimization, since this appears + to improve speed characteristics in some cases. + + 5.2. Alignment + + o Add an option to set the upper bound on correction steps. + o Move transformation data structure and related functions to a separate + header file. + + 5.3. Transformation data files + + o Add support for loading and saving transformation data. + +4. Version 0.2.0, 2003-Jan-01 + + 4.1. Alignment + + o Add support for general projective transformations, and change/add + options as follows: '--translation' used to be '--no-rotate' + '--euclidean' used to be '--rotate' '--projective' is a new option + +3. Version 0.1.2, 2002-Dec-13 + + 3.1. Image files + + o Add optional support for .jpg, .png, .tiff, and other file formats + through ImageMagick. Translation using ImageMagick was suggested by + Nick Rusnov. + o Don't segfault if a file can't be opened. + +2. Version 0.1.1, 2002-Dec-09 + + 2.1. Alignment + + o Use reduced levels of detail in coarser alignment steps to increase + speed. + o Change perturbation step lower-bound check from less-than ('<') to + less-than-or-equal-to ('<='). Change default lower bound to .125 from + .1 (the behavior is the same, but the value makes more sense). + o Change perturbation initial value to 32 pixels from 16 pixels, since + coarse alignment is now less expensive. + + 2.2. Rendering + + 2.2.1. Scale + + o Modify scale function so that the borders aren't corrupted (too + badly). + +1. Version 0.1.0, 2002-Nov-26 + + 1.1. Build + + o Add a rule for ale.exe to the Makefile. + + 1.2. Alignment + + o Add support for correction of rotation about the lens axis. + o Add an option to adjust minimum step-size. + o Add flags to specify which channels to use for alignment. Use a + summation of all channels by default. + o Add an option to modify the error metric exponent, and change the + default value from 1 to 2. + + 1.3. Rendering + + o Add an optional match criterion for merging. + + 1.4. User interfaces + + o Display information about how well a new image matches the accumulated + image. + +0. Version 0.0.0, 2002-Oct-11 + + 0.1.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *Note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..961184c --- /dev/null +++ b/Makefile.am @@ -0,0 +1,79 @@ +# Copyright 2006 David Hilvert , +# + +# This file is part of the Anti-Lamenessing Engine. +# +# The Anti-Lamenessing Engine is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# The Anti-Lamenessing Engine is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Prerequisites for building on Windows + + Successfully running the configuration script on Windows (e.g., for native + builds) may require installation of Cygwin. For more information on + Cygwin, see: + + o http://www.cygwin.com/ + + Alternatively, this package can be cross-compiled for Windows on a + non-Windows architecture, provided that the appropriate cross-compilers + and libraries are available. + + 1.3. Extraction + + Download the source archive file from the URL indicated in the section + 'URLs', and invoke: + + tar xzf ale-0.9.0.3.tar.gz + cd ale-0.9.0.3 + + Invoking 'ls configure' afterward should reveal an executable script + 'configure'. This script is used to determine the capabilities of the + system that will run the software. + + 1.4. Running configure + + This package uses a configuration script, 'configure', generated by the + GNU project build tools ("autotools"). For most cases, it should be + sufficient to invoke: + + ./configure + make + make install + + In cases where the defaults are not adequate, configuration options can be + passed to the configuration script. + + 1.5. Configuration options + + Configuration options can be passed to the 'configure' script prior to + build and installation, as: + + ./configure --config-option1 --config-option2 ... + make + make install + + Options specific to this package are described in the following + subsections. General configuration options are described in the file + 'INSTALL' included in the source package. + + 1.5.1. ImageMagick Support + + Enabling ImageMagick support allows ALE to make use of the file-handling + capabilities of ImageMagick ( http://imagemagick.org/ ). This includes + reading and writing a variety of file formats, including, among many + others, PNG and JPEG (two formats commonly used in web publishing) as well + as common interchange formats such as PPM and TIFF. ImageMagick 6.0.6 is + known to work with this version of ALE; certain older versions of + ImageMagick may cause compile, link, or runtime errors. By default, + support is automatically detected. + + --with-imagemagick=auto Auto-detect ImageMagick support [default] + --with-imagemagick=yes Enable ImageMagick support + --with-imagemagick=no Disable ImageMagick support + + 1.5.2. Color Data Precision + + ALE's internal data structures store each color channel within a pixel as + floating-point data; similarly, arithmetic operations on color channels + are performed in floating point. The available data-type configurations + are listed below, with typical data sizes indicated in parentheses. + + --with-colors=single Use C++ 'float' data type (32-bit) [default] + --with-colors=double Use C++ 'double' data type (64-bit) + + 1.5.3. Coordinate Data Precision + + In general, coordinate transformations used by ALE produce results outside + of the set of integers; hence, coordinates are treated as floating-point + data. The two available data-type configurations are listed below, with + typical data sizes indicated in parentheses. + + --with-coords=single Use C++ 'float' data type (32-bit) [default] + --with-coords=double Use C++ 'double' data type (64-bit) + + 1.5.4. Thread support + + Threads can improve performance on multiprocessor machines. POSIX threads + are currently supported. + + --enable-threads=auto Auto-detect thread support. [default] + --enable-threads=yes Enable thread support. + --enable-threads=no Disable thread support. + + 1.5.5. FFTW Support + + This feature is required in order to use the --fl option; it also + determines the approach to calculation of discrete Fourier transforms used + by the Irani-Peleg renderer. For more information on FFTW, see + http://fftw.org/. + + --with-fftw3=auto Auto-detect FFTW3. [default] + --with-fftw3=yes Use FFTW3 discrete Fourier transform. + --with-fftw3=no Use built-in discrete Fourier transform. + + 1.5.6. Enable --wmx + + This build option is required in order to use the --wmx option. If + --enable-wmx is specified, it is expected that fork() and execlp() calls + are available. + + --enable-wmx=auto Automatically detect whether to enable --wmx + --enable-wmx=yes Enable --wmx + --enable-wmx=no Do not enable --wmx + + 1.5.7. Getsize + + This build option is required to obtain additional output from --ui=tty. + If TIOCGWINSZ is not defined in , however, additional output + will not be provided even if --enable-getsize is specified at build time. + + --enable-getsize=auto Check for TIOCGWINSZ at build time. [default] + --enable-getsize=yes Configure to attempt to use TIOCGWINSZ + --enable-getsize=no Do not attempt to use TIOCGWINSZ + + 1.5.8. Assertions + + Finding bugs within ALE, or within custom modifications to ALE, can be + simplified by enabling run-time assertions. These checks enforce + conditions believed to be necessary or desirable for correct program + operation. If a condition is not satisfied, ALE will abort and display a + message indicating the failed assertion. + + --enable-assertions Enable assertions. [default] + --disable-assertions Disable assertions. + + 1.6. Cross-compilation + + For cross-compilation, it may be necessary to specify both host and build + machine types, using the configure --host and --build options. For more + information on these options, see the file 'INSTALL' in the source + package. + + 1.7. Further details + + General operation of the configure script is described in more detail in + the file 'INSTALL' in the source package. + +2.

PSF windowing and infinite-support PSFs for Irani-Peleg rendering + + o Add syntax for PSF windowing and new PSF types with infinite support, + including the gaussian kernel, suggested by HJ Hornbeck. + + 1.5. Variable lighting + + o Add a facility for handling variation in lighting between input + frames. + + 1.6.

Raw file handling + + o Use Dave Coffin's dcraw program to extract information from raw files, + including pixel data, as well as black level and other meta-data, as + suggested by Gregory Maxwell. + + 1.8. Abstract and partial transformations + + o Add a generic 2D transformation class, supporting partial + transformations. + o 'partial transformation', as used here, means that it is expected + that some points will fail to map. + o Add a partial 2D transformation class with constructor taking as + arguments a pair of 3D projective transformations and a 3D model. + + 1.9. File scoping + + o Add new file-scoped options + o Irani-Peleg + o black level + o alignment type + o focus details + + 1.10. Irani-Peleg for 3D models + + o Modify existing Irani-Peleg code to use generic (partial) 2D + transformations. + o in combination with the above, this should allow the algorithm to + operate on 3D models. + + 1.11. Focus bracketing for depth-of-field expansion + + o Add facilities for handling depth-of-field and focus bracketing in + input image sets, as suggested by Viktors Rotanovs and Gregory + Maxwell. This change will likely involve: + o using the 3D model for depth data, as suggested by Gregory + Maxwell + o using user-provided (file-scoped) focus details to determine + depth of field + o using variable PSF in the Irani-Peleg algorithm, as suggested by + Gregory Maxwell + o developing an approach to handle the incremental + (non-Irani-Peleg) case. + + 1.12. Output image characteristics + + o Allow specification of output image characteristics, including + exposure (e.g., gamma) and channel offsets within a pixel. + + 1.13. Output devices + + o Add support for specifying output devices, such as LCD monitors, to + allow shorthand customization of exposure (e.g., gamma) and other + characteristics, such as channel offset in the case of LCD screens for + sub-pixel anti-aliasing. + + 1.14. Weight and certainty upper bounds + + o Add support for specifying weight and certainty upper bounds for + rendering, either as an absolute constraint or relative to average + weights, so that the overall contributions to an output pixel (or + channel) are constrained by weight. + + 1.15. Time locality + + o In combination with weight and certainty upper bounds, time locality + could be used to determine which frames are used to generate an output + pixel. As a special case of this, video stream processing could favor + frames having the smallest time difference from the target frame. + +2. 1.0.0 (Stable) + + 2.1. Performance + + o Refine rendering and alignment code for better performance. + + 2.2. Synchronized frame set syntax + + o Add syntax to identify synchronized frame sets. + + 2.3. Internationalization + + o Enhance the command-line interface in preparation for i18n. (?) + o e.g., syntax for identifying synchronized frame sets + o Internationalize the command-line interface and help text to + accommodate translations. + + 2.4. Technical Manual Updates + + o Update the Technical Manual for information regarding 3D operation. + +3. Unsorted + + 3.1. Documentation + + o Generate correctly indented book-level tables of contents when + rendering the complete set of manuals. + o Add a tutorial, and credit Metin Toyran for suggesting a step-by-step + guide. + o Remedy meaningless page numbers for book title pages in the set ToC. + o Complete migration of existing documentation from the localhost + sub-directory, removing superfluous license terms in the footers. + o Centralize licensing and authorship information (e.g., there should be + only one COPYING file and only one AUTHORS file). + o Include license and copyright terms for the doc tree Makefile as + copyright notices in the AUTHORS and/or COPYING files (or equivalent). + o Complete the documentation. + o Revise the user manual for new features and syntax. + o Document new scoping operators {}, [], and [<>]. + o Document other changes in UI, including regularization of syntax. + + in particular, commas can no longer appear in + single-argument options when using assignment-delimited + syntax; use space-delimited syntax instead. This behavior is + inconsistent with 0.8.4. + + 3.2. Integer-value routines + + o Add facilities for manipulating images storing color as integer-valued + data, possibly as library routines. + + 3.3. Library + + o Move image-processing routines into a library that can be used by + other programs. + + 3.4. Language Bindings + + o Add bindings for other programming languages. + + 3.5. Packaging + + 3.5.1. Complete Package + + o Investigate options for distributing a 'complete' package including + full revision history, pre-built documentation (if the ordinary + distribution does not include this), and, possibly, example image + sets. Direct download, bittorrent and CD are the most prominent + candidates for distribution. + o In the case of CD distribution, information should probably be + added to the manuals regarding how to update CD-provided program + source. + + 3.5.2. Windows Package + + o Investigate options for creating and distributing a combined source + and binary Windows package containing sufficient software to ensure + support for common image types (e.g., by statically linking with + libraries for opening JPEG and PNG files). BitTorrent and CD are the + most obvious candidates for distribution. + o This package could build on the package described above, as a + 'for Windows' variant or some such. + o This package could make use of an application such as + InstallJammer or Nullsoft Scriptable Install System for + installation. diff --git a/VERSION b/VERSION new file mode 100644 index 0000000..abf94cd --- /dev/null +++ b/VERSION @@ -0,0 +1 @@ +0.9.0.3 diff --git a/aclocal.m4 b/aclocal.m4 new file mode 100644 index 0000000..6f49652 --- /dev/null +++ b/aclocal.m4 @@ -0,0 +1,1348 @@ +# generated automatically by aclocal 1.10.2 -*- Autoconf -*- + +# Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, +# 2005, 2006, 2007, 2008 Free Software Foundation, Inc. +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.63],, +[m4_warning([this file was generated for autoconf 2.63. +You have another version of autoconf.

Summary

+ +Between versions 0.5.1 and 0.7.0, alignment times show a steady improvement, +but this can be partly explained by a change in the default alignment settings +in 0.7.0. Rendering times, on the other hand, are about 6 times longer for +0.7.0 than for 0.5.1, as a consequence of renderer changes. More detailed +summaries for alignment and rendering tests follow. + +

Alignment

+ +

Alignment times improve as the version number increases, through version +0.7.0, but note that version 0.7.0 with the --q0 option defaults to --mc 30, +which offers less accurate alignment than is offered by other versions' +configurations. (Instead of sampling the difference between images for each +reference image pixel, --mc 30 specifies that differences be sampled at roughly +30% of reference image pixels.) + +

Rendering

+ +

Rendering times increase significantly with version number, through version +0.7.0, the most significant increase being between 0.6.0 and 0.7.0, as the +latter uses a computationally more expensive rendering technique. Whether the +improved rendering quality is worth the extra rendering time likely depends on +subjective criteria, but the differences seem to be most apparent when +performing relatively complex rendering tasks.

Error Functions

+ +

Error functions are used to determine whether a transformation is "good" or +not, and in particular, whether one transformation is better or worse than +another. In particular, a smaller error indicates a better transformation. + + + +

ALE defines error functions for each pixel of the accumulated image, and +also a comprehensive error function that summarizes the error over all +pixels. + +

Per-Pixel Error Functions

+ +

Since differences in exposure may alter the absolute values of pixels even +in images that are perfectly aligned, ALE usually normalizes the images so that +overall image intensity matches. This normalization step does not affect the +pixel values contributing to the merged image, but it does affect the values +with which the per-pixel error function is calculated. (The normalization +step is skipped when --extend or --follow is specified.) + + + + +

The per-pixel error function for pixel (i, j) in the accumulated +image A, frame B, and transformation T, is: + +

+
+p(i, j, A, B, T) = Abs( A(i, j) - B(T_inverse(i, j)) )metric_exponent
+
+
+ +

where Abs() is the absolute value function and B(T_inverse(i, j)) +is the overlapping value described in the merging section. +If not specified by the --metric option, metric_exponent defaults to 2.0 +for ALE versions 0.1.0 and later, or 1.0 for version 0.0.0. + +

In addition to the per-pixel error function, a per-pixel maximum error +estimator is calculated, as follows: + +

+
+p_max(i, j, A, B, T) = Max( A(i, j), B(T_inverse(i, j)) )metric_exponent
+
+
+ + +

Comprehensive Error Functions

+ +There are two varieties of comprehensive error function used by ALE: an +exhaustive error function and, in versions 0.4.3 and later, a +Monte Carlo error function. Whereas the exhaustive function +evaluates the error for each pixel in the accumulated image, the Monte +Carlo function evaluates only a subset of pixels. +

If we consider Sum[] to provide the sum over whatever +subset of pixels we are sampling (including possibly the set of all pixels), then +the comprehensive error function, for accumulated image A, frame +B, and transformation T, is: + +

+
+E(A, B, T) = (Sum [ p(i, j, A, B, T) ] / Sum [ p_max(i, j, A, B, T) ])(1/metric_exponent)
+

Monte Carlo Error Function

+ +Monte Carlo alignment can decrease the time required to align large images, +since calculating transformations for every pixel is usually expensive. +Sections in this page describe the motivation for Monte Carlo alignment, the +ratio calculations used, the sampling algorithm, cache behavior for the +algorithm, randomization approaches, typical deviations from the specified +ratios, special handling of level-of-detail, and practical observations +regarding the use of Monte Carlo alignment. + +

Motivation

+ +Transforming large numbers of points in order to determine alignment error can +be very computationally expensive. One approach to mitigating this expense is +to use reduced level-of-detail. However, using reduced level-of-detail can +also reduce alignment precision. In particular, reducing the level of detail +by a factor of two can make impossible the task of precisely aligning a +horizontal line one pixel high. However, if just a few pixels from the line +are sampled at full detail, exact alignment is possible. + +

Ratio Calculations

+ +

In Monte Carlo alignment, a ratio + +

+s = (expected # of pixel +samples) / (# of total pixels in the accumulated image) +
+ +is specified. From this ratio, a new ratio + +
+u = (expected # of unsampled pixels) / (expected # of sampled pixels) +
+ +is calculated. Pixels are sampled in such a manner that u is +approximately satisified. + +

Sampling Algorithm

+ +

Pixels are considered in order of index, where the accumulated image pixel +at position (i, j) is numbered with an index (i * width + j). +In order of index, we skip and sample pixels in such a manner that the +expected size of a run of consecutive skipped pixels preceding a sampled pixel +is u. We select the size of each run of consecutive skipped pixels as +follows: + +

If 2 * u is an integer, then we draw uniformly from integer values in +the interval [0,2u]. If it is not an integer, then we draw from integer values in +the interval [0,2u + 1] in such a manner that integer values in +[0,2u] are equally likely to be chosen. (There is only one probability +distribution of this kind that satisfies the expected value u. Version +0.4.3 deviates slightly from this distribution, and so a deviation in the +expected value of s occurs, as outlined in this table. This problem is fixed in version 0.4.4.) + +

(Also, see the section below on interaction with level-of-detail.) + +

Cache behavior

+ +

Since indices are monotonically increasing in memory address, this approach +to sampling may make effective use of memory cache where other approaches (e.g. +repeated random draws from the entire index space) would not. + +

Randomization

+ +ALE versions 0.4.7 and earlier do not reseed the pseudorandom number generator, +and so a new random subset is selected every time the error function is +evaluated. Hence, as more or fewer of the pixels critical to alignment are +sampled, the reported alignment can worsen or improve even in the absence of +any change in transformation. + +

With this approach, since many transformations are inspected during the +alignment of any given frame, it is likely, especially with greater precision +of alignment, that some measured differences between transformations are due to +a difference in sample sets rather than a difference in alignment accuracy. + +

By reseeding the pseudorandom number generator, ALE versions 0.4.8 and later +instead use a consistent set of pixels from the accumulated image when +comparing two transformations. Tests sampling 3% of pixels from a set of +320x240 frames indicate that this approach improves alignment. + +

Sampling characteristics

+ +For an image with 100,000 pixels and specified +s in the interval [0.005,0.995], ALE's sampling method results in +a ratio s within 0.000003 of the specified s. This number +improves with image size. These results are outlined in the table linked +above. However, note that s only represents an expected value, and the actual number +of sampled pixels may vary by more than the numbers given here. + +

Interaction with level-of-detail

+ +

When reduced level-of-detail is used, the number of reduced-detail pixels +sampled is taken to be a percentage of the total number of pixels in the +full-detail image, rather than as a percentage of the total number of pixels in +the reduced-detail image. (When this fraction of pixels in the full-detail +image is more than the number of reduced-detail pixels available, all +reduced-detail pixels are used.) This may improve the likelihood of successful +alignment, but may also add overhead to the alignment process. + +

Use of Monte Carlo Alignment

+ +

If it is not known in advance what settings will work well for a series of +frames, it may be desirable to begin by sampling a small percentage of pixels, +saving the results of alignment, and then, if the output suggests that proper +alignment is occuring, performing more precise alignment with a larger +percentage of pixels on later passes, using smaller perturbation upper bounds. +If alignment problems occur on the first pass, the percentage of pixels can be +increased and alignment performed again.

Alignment

+
+ALE aligns each supplemental frame, in sequence, with the merged rendering
+representing all previous frames.  This page outlines the three supported
+transformation classes, the algorithm used for alignment, and the properties of
+the alignment algorithm.  Following this is a discussion of practical use of
+alignment options, including alignment classes and alignment in the case of
+extended renderings.
+
+
Transformations

+
+
ALE offers three classes of transformations: 

+
+
+
+
+
+
Translationsintroduced in version 0.0.0
Euclidean transformations (excluding reflections)introduced in version 0.1.0
Projective transformationsintroduced in version 0.2.0

+
+
+
+
Algorithm

+
+
Alignment proceeds by a deterministic search, beginning with an initial
+transformation and modifying this transformation through a series of
+perturbations.
+
+
The initial transformation may be loaded from a file or selected by default.
+The default initial transformation is either the identity transformation or
+(when the --follow option is specified) the most recently merged
+frame's final alignment.  (Note that changes in release 0.5.0 are not reflected
+here; these changes affect the interaction of the --follow and --trans-load
+flags.)
+
+
Once the initial transformation is determined, an initial perturbation
+amount is selected, and represents the step size by which each of the
+transformation parameters are changed.  In translational or Euclidean
+alignment, the perturbation amount is applied to translation -- in units of
+pixels on the two image axes -- and rotation -- in units of degrees about the
+image center.  (In version 0.4.8 and later, an additional configurable upper
+bound constrains rotational perturbation separately, preventing, e.g., a
+360 degree perturbation of rotation.)  In the case of projective alignment, the
+perturbation amount is applied to the position of the corners of the projected
+quadrilateral in units of pixels, where the projection is from the boundary
+of the supplemental image into the coordinate system of the accumulated image.
+
+
If possible, transformation parameters are changed to decrease the error between the two images being
+aligned.  The perturbation amount is halved whenever it is determined that no
+parameter change of this size improves the alignment of the images.  A lower
+bound on the perturbation amount determines when the alignment is complete.
+
+
The order in which parameters are considered for change is specified in the
+source code, and has the following property: No modified parameter is
+considered for further change until all other parameters have been considered.
+A consequence of this property is that parameters are always considered in a
+fixed (round robin) order.
+
+
When multiple levels of detail are used, the error may be calculated on
+images with a reduced level of detail.  ALE versions 0.1.1 through 0.4.7 use a
+level of detail twice as fine as the perturbation amount for perturbation
+amounts larger than two, and full detail otherwise.  Later versions default to
+this behavior, but can be configured differently.  Earlier versions do not use
+reduced levels of detail.
+
+
Properties

+
+
Several assumptions were made throughout the design and testing of the
+algorithm outlined above.  These assumptions are outlined below.
+
+
The algorithm is based on a hill-climbing approach, which requires that any
+local minimum reachable from the starting point by traveling a path of
+decreasing error is also a global minimum (or, in this case, the correct
+alignment).  While it is possible that the algorithm outlined above succeeds in
+some cases for which hill-climbing fails, it is still susceptible to entrapment
+in local minima.
+
+
As outlined above, depending on program options, transformation parameters
+may be changed by perturbations of several units (degrees or pixels) early in
+the alignment process.  As long as no change of this magnitude moves the
+transformation out of the 'bowl' in which the minimum error -- and hence
+correct alignment -- lies, this is not a problem.  However, it might break in
+some cases where a hill-climbing approach would succeed.  (Notably, simulated
+annealing suffers from a similar problem, and it seems likely that a case could
+be constructed in such a way that the algorithm outlined above -- like
+simulated annealing -- could, contrarily, succeed where hill-climbing fails.)
+
+
Finally, the use of reduced level-of-detail relies on a high signal-to-noise
+ratio at low frequencies.  Fortunately, this assumption seems to generally
+hold, but camera defects or radio interference could violate the assumption,
+possibly resulting in misalignment.
+
+
Use of Alignment Classes

+
+
ALE is likely to be most useful when corresponding regions of different
+frames can be aligned by one of the available alignment classes.
+
+
As described by Steve Mann in his work on Video Orbits, the projective
+transformation offers particular versatility for camera imaging of (ideal
+Lambertian) flat scenes.  In this case, any change in camera position and
+orientation can be corrected as long as points always have a defined projection
+onto the rendering plane (for which ALE uses the base of the pyramid
+R1).
+
+
In camera imaging of scenes with depth, correction for orientation is almost
+the same as for flat scenes, since, if focus and lens distortion is ignored, a
+scene with depth is indistinguishable from a flat scene from the perspective of
+a camera whose position is fixed.
+
+
For sequences of camera images with small changes in position or
+orientation, the projective transformations for alignment may closely
+approximate Euclidean transformations; in this case, using Euclidean
+transformations may achieve similar results and may require less time for
+alignment, since there are fewer parameters to tweak (three parameters
+instead of eight).
+
+
In the case of flatbed scanners that preserve the relative height and width
+of scans, any change in the position or orientation of flat objects can be
+corrected using the Euclidean alignment class.

+
+
If a flatbed scanner does not preserve relative height and width, but does
+preserve straight lines, then any change in the position or orientation of flat
+objects can be corrected with the projective alignment class.
+
+
However, even if a transformation is within the alignment class used, the
+alignment algorithm may still be unable to determine large transformations.
+
+
Alignment in the case of Extended Renderings

+
+
By using the --extend flag, ALE can be used to create image mosaics spanning
+a spatial region larger than that represented by any single image in the frame
+sequence.  In these cases, if adjacent frames in the sequence tend to be more
+closely aligned with each other than they are with the original frame, it may
+be helpful to also use the --follow flag as a hint to the alignment algorithm.

Drizzling Renderer

+
+
ALE versions 0.4.1 and later implement a drizzling algorithm based on that
+outlined in research by Richard Hook and Andrew Fruchter.1  
+
+
Algorithm

+
+
In the drizzle rendering method, pixels from source images are considered to
+span an area smaller than the original source pixel (a 'reduced footprint');
+these source images with reduced pixel footprint are transformed for alignment,
+and the reduced-area pixels from all transformed source images are combined to
+form the target image, where each source pixel contributes to each target pixel
+linearly with the area of overlap after transformation.  
+
+
ALE uses an approximation to the above approach, wherein the area of overlap
+is calculated in the coordinates of the source image and then multiplied by a
+factor approximating any difference in scale between the source and target
+images; for the purpose of these calculations, the region of the target pixel
+is approximated by a rectangle in the source coordinate system having all sides
+parallel to the source image coordinate axes.
+
+
Properties

+
+
Assuming small drizzling radius, drizzling is approximately the same as
+convolution of discrete pixel data with a box filter having the same radius as
+the chosen drizzling radius.  For a very large, uniform input sequence, point
+sampling with simple optics, and sufficiently small radius, drizzling should
+provide an acceptable approximation of T.
+
+
+

+"Variable-Pixel Linear Combination", published in vol. 125 of the ASP
+Conference Series (eds. Gareth Hunt and H. E. Payne).  This paper was also

High-Frequency Enhancement Renderer

+
+
The High-Frequency Enhancement Renderer is a built-in post-processing
+step based on the unsharp mask technique, which has been used to enhance high
+frequencies since the days of photographic plate processing (see, for example,
+this
+page).  This renderer acts after all other rendering steps have completed,
+except for Irani-Peleg Iterative Image Reconstruction, which occurs afterward.
+
+
(The remainder of this text outlines version-specific information and offers no
+further justification for rendering predicates.)

Release 0.3.1

+
+
The filter in release 0.3.1 acts on a square region, centered on the pixel
+to be filtered, where the length of each side of the square is linear with the
+scale factor (arbitrarily selected to be 2.5 times the scale factor).  The
+pixel being filtered makes a positive contribution weighted with the total area
+of the filter region, and all pixels coincident with the filter region make a
+negative contribution weighted with the area in which the pixel is coincident
+with the filter region.  
+
+
This filter was chosen primarily due to its implementation simplicity and
+also for its satisfaction of the following two criteria: 
+
+
First, the filter value returned for a uniformly valued pixel array is zero.
+ Hence, when the pixels in the region of the filter support do not vary in
+value, the high-frequency filter returns zero.  This seems to be a
+reasonable requirement for a high-frequency filter.  
+
+
Second, the filter support for a pixel closely corresponding to given pixel
+in the original (unscaled) frame spans a region corresponding to a neighborhood
+of pixels in the original frame that is roughly independent of the scale factor.  
+
+
In release 0.3.1, the filter result described above was divided by 100, so that
+an enhancement factor of 1.0 would look reasonable for an image that had been
+scaled up by a factor of 4.  This division step is replaced by a more general
+and elegant normalization step in release 0.4.0.
+
+
Since this filter requires a square region of pixels centered on the pixel
+to be filtered, it cannot operate near the boundary of an image.  We avoid this
+problem in release 0.3.1 by not filtering near the boundary of images.
+
+
Release 0.4.0 and later

+
+
The filter in release 0.4.0 was modified from the filter in release 0.3.1 in two 
+ways: 
+
+
First, the filter was extended to operate near the boundaries of an image.  When
+necessary, the filter region is constrained so that it fits within the boundary
+of the image.  (However, the notion of boundary used does not yet elegantly accommodate 
+the non-rectangular boundaries that may occur when image extents are increased.)
+
+
Second, the filter was normalized so that the filtered pixel makes a
+positive contribution with unit (1) weight, and all pixels coincident with the
+filter region make a negative contribution with weight a/A, where
+a is the area in which the pixel is coincident with the
+filter region and A is the total area of the filter region.  
+
+
This change provides the following nice property that did not hold for the
+filter in release 0.3.1:
+
+
Filtering and then scaling is almost the same as scaling and then filtering.
+
+
Hence, a given high-frequency enhancement argument in ALE will achieve
+roughly similar results regardless of scale factor.  This behavior should be
+less surprising than the behavior in 0.3.1, in which merely increasing the
+scale factor argument could cause pixel values to become distorted as they
+eventually collided with the limits of the image format.

+having:

+
+
    
+
  • Reduced noise.
+
  • Reduced aliasing.
+
  • Increased dynamic range.
+
  • Increased spatial resolution.
+
  • Increased spatial extents.
+

+
+
This page provides information on related work, models of program input, an
+outline of renderers, and an overview of the algorithm used in ALE.  

+
+
Note: This document uses PNGs and HTML 4 character entities.

+
+
Related Work

+
+ALE derives one of its rendering techniques from a
+method developed by Richard Hook and Andrew Fruchter for combining dithered
+images.
+
+
Steve Mann's work in Video Orbits
+on increased spatial extents and the use of projective transformations has
+influenced features incorporated by ALE.
+
+
ALE incorporates an iterative solver based on the work
+of Michal Irani and Shmuel Peleg on image reconstruction.

+
Models of Program Input

+
+
Definition of Discrete and Continuous Images

+
+
Using R+ to represent the non-negative real numbers, a
+discrete image D of size (d1,
+d2) is a function 
+
+

+D: {0, 1, …, d1 - 1}×{0, 1, …, d2 - 1} → R+×R+×R+
+

+
+A continuous image I of size (c1, c2) is a function
+
+

+I: [0, c1]×[0, c2] → R+×R+×R+
+

+
+
+
+
In this document, a member of the set
+R+×R+×R+ is sometimes called an
+RGB triple.
+
+
Definition of a Camera Snapshot

+
+
A camera snapshot is defined as an n-tuple consisting of:

+
+
    
+
  • A scene S.
+
  • A pyramid R with rectangular base.
+
  • A continuous image I.
+
  • A discrete image D.
+
  • A function i such that i(S, R) = I. 
+
  • A function d such that d(I) = D.
+

+
+
S represents a physical scene.

+
+
R represents the viewing volume of a physical camera.
+
+
The value I(x, y) is the RGB triple representing the radiance
+that would be recorded from S by a directional light sensor
+located at the apex of R and aimed at the point (x,
+y) on the base of R.  The only constraint on the sensor
+is that, given a fixed scene S,  it must return a unique value
+for a given position and orientation.  This sensor is assumed to be the same
+for all camera snapshots, and is called the canonical sensor.

+
+

+
+

+
Positioning of the canonical sensor
+

+

+
+
+
D represents the discrete pixel values reported by the
+camera.

+
+
The composite function composite(d, i) represents the optical
+and electronic properties of the camera. 
+
+
Definition of a Camera Input Frame Sequence

+
+
For positive integer N, a sequence of camera snapshots
+{ C1, C2, …, CN }, defined by the
+n-tuples { Cj = (Sj, Rj, Ij, Dj,
+ij, dj) } is a camera input frame sequence if,
+for all j and j', Sj =
+Sj' and ij = ij'.
+
+
Definition of a Diffuse Surface

+
+Given a camera input frame sequence { C1, C2,
+…, CN }, defined by the n-tuples
+{ Cj = (S, Rj, Ij, Dj, i,
+dj) }, a surface in S is diffuse if the
+radiance of each point on the surface (as measured by the canonical sensor) is
+the same for all views Rj from which the point is visible.
+
+
Definition of the Extended Pyramid

+
+
If the view pyramids { R1, R2, …,
+RN } of a sequence of N camera input frames all share a
+common apex and can be enclosed in a single rectangular-base pyramid R
+sharing the same apex and having base edges parallel to the base edges of
+R1, then the smallest such R is the extended pyramid.
+Otherwise, the extended pyramid is undefined.

+
+
If a camera input frame sequence has an extended pyramid R, then an
+extended image is defined from R in a manner analogous to the definition
+of the image I from the view pyramid R in the
+definition of a camera snapshot.
+
+
Definition of a Projective Snapshot

+
+
A projective snapshot is defined as an n-tuple consisting of:

+
+
    
+
  • A continuous image Σ.
+
  • A continuous image I.
+
  • A discrete image D.
+
  • A projective transformation q such that I = composite(Σ, q)
+
  • A function d such that d(I) = D.
+

+
+
Σ represents the subject of the
+snapshot (somewhat analogous to S in the camera snapshot).
+
+
D represents discrete pixel values reported by the physical
+imaging device.
+
+
Definition of a Projective Input Frame Sequence

+
+
For positive integer N, a sequence of projective snapshots {
+P1, P2, …, PN }, defined by the
+n-tuples { Pj = (Σj, Ij,
+Dj, qj, dj) } is a projective input
+frame sequence if, for all j and j', Σj =
+Σj'.
+
+
The first frame in the sequence of input frames is called the original
+frame, and subsequent frames supplemental frames.
+
+
Construction of Projective Input Frame Sequences from Camera Input Frame Sequences

+
+
From a camera input frame sequence, define a continuous image
+Σ as follows:
+
+
    
+
+
  • If an extended pyramid is defined for the set of camera input frames, then
+Σ is the associated extended image.  

    
+
+
  • If an extended pyramid would be defined if all pyramids
+Rj were translated to share a common apex, and the scene
+S represents a physical configuration presenting to the camera only a
+single planar, diffuse surface, then define Σ so that there
+exists some projective transformation p such that Σ(p(x))
+indicates the radiance at point x on the surface.
+
+

+
+If such a Σ exists, then each camera input frame 
+
+

+Cj = (S, Rj, Ij, Dj, i,
+dj)
+

+
+admits a projective input frame
+
+

+Pj = (Σ, Ij, Dj, qj, dj)
+

+
+for some qj, and these { Pj } form a
+projective input frame sequence.
+
+
Definition of a Projective Renderer without Extension

+
+
For a projective input frame sequence { Pj = (Σ,
+Ij, Dj, qj, dj) }, a
+projective renderer without extension is an algorithm that outputs a
+discrete image approximation of I1.  The assumptions used in
+calculating the approximation vary across rendering methods.
+
+
Definition of a Projective Renderer with Extension

+
+
For a projective input frame sequence { Pj = (Σ,
+Ij, Dj, qj, dj) }, a
+projective rendering method with extension is an algorithm that outputs
+a discrete image approximation of Σ.  The assumptions used in
+calculating the approximation vary across rendering methods.
+
+
Renderers

+
+
+
Extension

+
+
All renderers can be used with or without extension (according to whether the
+--extend flag is used).  The target image for approximation (either
+Σ or I1) is generically called T.
+
+
Renderer Types

+
+
Renderers can be of incremental or non-incremental type.  Incremental
+renderers update the rendering as each new frame is loaded, while
+non-incremental renderers update the rendering only after all frames have been
+loaded.

+
+
Incremental renderers contain two data structures that are updated with each
+new frame: an accumulated image A with elements Ax, y
+and the associated weight array W with elements Wx, y.
+The accumulated image stores the current rendering result, while the weight
+array stores information about contributions to each accumulated image pixel.
+
+
Renderer Details

+
+These pages offer detailed descriptions of renderers.
+
+
+
+
Rendering Predicates

+
+
Renderers should output approximations of T when certain predicates
+are satisfied.  Not all of these predicates are required for all renderers, and
+renderers may produce acceptable output even when their predicates are not
+satisfied.

Predicate
+Explanation
AlignmentThe projective input frame transformations qj are known.
TranslationAll projective input frame transformations qj are 
+translations.
Point sampling with simple opticsdj assigns Dj(x) = Ij(x).
+
Very large, uniform input sequenceA large number of input frames are provided, uniformly sampling the domain
+of T.
+
Small radiusThe radius parameter used with the rendering method is chosen to be
+sufficiently small.
+
Barlett filter approximationConvolution of T with a Bartlett filter remains an acceptable
+approximation of T.
+
USM approximationApplying the unsharp mask employed by the ALE --hf-enhance option to the
+output of drizzling or merging produces an acceptable approximation of
+T.
+
Correct Projection FilterThe projection filter used in Irani-Peleg rendering approximates
+dj.
+
Low Response ApproximationFrequencies having low response in the Fourier domain representations of
+dj need not be accurately reconstructed in the Fourier
+domain representation of program output.
+
ConvergenceIterating Irani-Peleg on the input frames will eventually produce an
+acceptable approximation of T, and the number of iterations chosen is
+adequate to achieve this.  This predicate may entail the very large, uniform
+input sequence predicate.
+

+

+
+
Summary of Rendering Predicates by Renderer

+
+
The following table indicates which rendering predicates are associated with
+each renderer.  Note that renderers may produce acceptable output even when
+these predicates are not satisfied.  Justification for non-obvious entries in
+this table should appear in the detailed descriptions; for entries where this
+is not the case, the value given should be considered unreliable.

Space Complexity

+
+Image storage space in memory for all renderers without extension is
+O(1) in the number of input frames and O(n) in the number of pixels per
+input frame.  The worst-case image storage space in memory for all renderers
+with extension is O(n) in the size of program input.
+
+
Algorithm

+
+
First, a merging renderer is instantiated.  Then,
+program flags are used to determine what other renderers should be
+instantiated.
+
+
An iterative loop supplies to the renderers each of the frames in sequence,
+beginning with the original frame.  The drizzling and
+merging renderers are incremental renderers, and
+immediately update their renderings with each new frame, while the high-frequency enhancement and Irani-Peleg renderers do not act until the final frame
+has been received.
+
+
In the case of the incremental renderers, the original frame is used without
+transformation, and each supplemental frame is transformed according to the
+results of the alignment algorithm, which aligns each
+new frame with the current rendering of the merging
+renderer.
+
+
Once all frames have been aligned and merged, non-incremental renderers
+produce renderings based on input frames, alignment information, and the output
+of other renderers.

Irani-Peleg Renderer

+
+
ALE implements an iterative image reconstruction algorithm based on Michal
+Irani and Shmuel Peleg's paper "Improving Resolution by Image Registration",
+published in Graphical Models and Image Processing, Vol. 53, No. 3, May,
+pp. 231-239, 1991, or available at:
+
+
http://www.wisdom.weizmann.ac.il/~irani/abstracts/superResolution.html
+
+
This algorithm iteratively performs two steps: first, an
+approximation of T is projected, based on a filter approximating
+dj, and data collected during alignment, to create a set of simulated input frames;
+second, the per-pixel error -- between these simulated input frames and the
+actual input frames -- is calculated, backprojected, and subtracted from the
+approximation of T, resulting in a new approximation of T.
+
+
Initial Image Approximation

+
+
ALE uses the results of previous rendering steps as the initial image
+approximation.

+
+
Projection and Back-projection filters

+
+ALE provides command-line options for selecting forward-projection filters,
+including box filters (release 0.4.2 and later) and custom filters (release
+0.4.7 and later).  The back-projection filters are constructed so that the
+normalized back-projection weight between a given pixel in the approximation of
+T and a given pixel in an input frame is always equal to the
+corresponding normalized forward-projection weight.  This differs from the
+approach taken by Irani and Peleg.
+
+
Box Filter

+
+ALE versions 0.4.2 and later implement a box filter with user-specified
+diameter.  This is somewhat similar to the 'blur' operator used by some image
+editing applications, and in some cases, may be an adequate approximation
+for dj.
+
+
Custom Filters

+
+ALE versions 0.4.7 and later implement support for device-specific custom
+filters, including a filter calibrated for the IBM PC Camera Pro (XVP610) in
+320x240 mode.  Configurability by color channel and pixel position in the input
+frame is also supported, although the latter is not currently used by any
+filter included with ALE.
+
+
stdin Filter

+
+ALE versions 0.4.7 and later support limited configuration of filters at
+runtime from standard input, implemented through a custom filter called
+'stdin'.  This filter can be used with a script included in the source
+distribution to calibrate filters for devices with unknown properties.
+
+
Transformation details

+
+
ALE's method of transforming pixel areas between coordinate systems
+approximates transformed pixel boundaries with axis-aligned rectangular
+regions.  Since boundaries are transformed into the coordinate systems of the
+input frames, this approximation can be improved by using larger scale factors
+(and hence reducing the size of transformed pixels).

Merging

+
+Merging uses bilinear interpolation to determine each frame's contribution to
+the accumulated image, and each contribution is assigned equal weight.
+Sections below outline the merging algorithm and its properties.
+
+
Calculating the Overlapping Value

+
+
(This section is a very verbose explanation of bilinear interpolation.)
+
+
Determining what values from the new frame overlap pixels in the accumulated
+image is an important part of merging.  Since transformations may involve
+sub-pixel alignment, and the accumulated image may be configured to be of finer
+resolution than the input frames, the manner in which these values are
+determined is not necessarily obvious.  
+
+
ALE uses the following rules to determine the overlapping value:
+
+
    
+
  1. If the new frame overlaps the accumulated image pixel in such a manner that
+the accumulated image pixel is aligned with a pixel in the new frame, then the
+value of this pixel is the overlapping value.  

    
+
+
  2. If the point overlapping the accumulated image pixel falls on a line between
+two pixels in the new frame, then the overlapping value is a linear
+interpolation between these pixels in the coordinate system of the new frame.
+

    
+
+
  3. If the point overlapping the accumulated image pixel falls within a
+quadrilateral outlined by the four closest pixels in the new frame, then the
+overlapping value is a bilinear interpolation among these pixels in the
+coordinate system of the new frame.

    
+
+
  4. If none of the above conditions apply, then there is no overlapping value
+for the accumulated image pixel in the new frame.

    
+

+
+
Calculating the Merged Value

+
+
The merged value for an accumulated image pixel is a weighted average
+between the current accumulated image pixel value and the overlapping value.
+The weights are selected so that overlapping values from all frames contribute
+with equal weight.
+
+
Definition of Merging

+
+
Merging a new frame replaces the existing value of each accumulated
+image pixel with the merged value.
+
+
Properties

+
+
Density and false local minima

+
+
The merging method outlined above has the property of always updating a
+dense set of pixels in the accumulated image, even when the accumulated image
+is of finer resolution than the new frame.  This ensures that the area of
+defined pixels in the accumulated image is dense and that any uniform change in
+intensity is reflected uniformly over a dense area.  The absence of these
+properties may cause alignment to fail due to entrapment in local minima, and
+so merging is always used internally to create the renderings used by the
+alignment algorithm.  Except in the case of a large pixel footprint, drizzling does not share these properties.
+
+
Convolution with the Bartlett (triangle) filter as the limiting case

+
+
Assuming predicates for translation, point sampling with simple optics, and
+a very large, uniform input sequence, the result of merging is equivalent to
+convolution of pixel data with the Bartlett, or triangle, filter.  This is
+derived from the fact that bilinear interpolation of an image defined at
+discrete points is equivalent to convolution with a Barlett filter.  This
+property is still approximately true even when the translation predicate is not
+satisfied, so long as large changes in scale do not occur.
+

+
Alignment

+
+Alignment compares each supplemental frame in the sequence with an intermediate
+rendering known as the accumulated image.  Based on this comparison, a
+transformation is assigned to the supplemental frame.  Many different
+transformations can be assigned before alignment of the frame is complete.
+
+
Match statistics

+
+The match statistic is a single number indicating how well two frames are
+aligned.  After alignment is complete, ALE displays the final match statistic.
+If the value is close to 100%, then the frames are well aligned.  Very low
+values can indicate misalignment.  However, even frames that are very well
+aligned do not usually achieve 100% alignment, and for improving image quality,
+ALE works most effectively when match values are less than 100%.
+
+
Match threshold

+
+A match threshold can be specified; no images with final match statistics
+falling below this threshold will contribute to the final output.
+
+
+--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)
+

+
+
Error metric exponent

+
+The function calculated at each pixel to determine the match statistic is known
+as the error metric, and is of the form (a-b)x.  The value x is
+known as the error metric exponent, and is 2 by default.  Larger numbers
+usually mean that alignment will be more influenced by smaller image features.
+
+
+--metric=x        Set the error metric exponent.                 (2 is default)
+

+
+
Alignment Channel Options

+
+In calculating the per-pixel error metric, there are three ways in which ALE
+can handle color channels.  By default, ALE adds the channels before
+calculating the match.  However, ALE can also rely solely on the green color
+channel or use all three channels separately.
+
+
+--align-all       Align images using all color channels
+--align-green     Align images using the green channel
+--align-sum       Align images using a sum of channels [default]
+

+
+
Monte Carlo Alignment

+
+Aligning large images can take a very long time if all pixels are examined in
+determining the match statistic, so it is often desirable to examine a smaller
+number of pixels.  The Monte Carlo alignment option allows this.  The number of
+pixels used is specified as a percentage, and smaller numbers usually mean
+faster, but less precise, alignment.
+
+
+--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
+--no-mc           Align using all pixels.  [default]
+

+
+
Perturbation

+
+Every dot displayed after an input filename indicates a change in perturbation
+size.  The size is initially set to be high, allowing large changes in
+alignment to be evaluated, and is reduced as the locally optimal alignment is
+found for each size.  When this size drops below a specified lower bound, the
+frame is considered to be aligned.
+
+
Perturbation bounds

+
+These options determine the upper and lower bounds for perturbation size.  The
+perturb-upper and perturb-lower bounds apply to rotation (in degrees),
+translation (in pixels), and the movement of the boundaries of a projected
+frame (in pixels).  The rot-upper bound disables rotational perturbation above
+a certain perturbation size (in degrees).  To disable alignment, set
+perturb-upper to zero.
+
+
+--perturb-upper=x Perturbation upper bound in pixels/degrees  (32.0 is default)
+--perturb-lower=x Perturbation lower bound in pixels/degrees  (.125 is default)
+--rot-upper=x     Rotation-specific perturbation upper bound  (32.0 is default)
+

+
+
Level of detail

+
+
Alignment at large perturbation sizes is usually carried out on
+reduced-detail images.  To disable this, set lod-max to
+log2(perturb-upper).
+
+
+--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)
+

+
+
Transformations

+
+The variables used to adjust alignment are called transformations, and map
+points from a source image to a target image.  
+
+
There are three transformation classes that can be used by ALE.  The
+translational class applies only translations to the inputs, changing only the
+position of images; the Euclidean class applies translations and rotations; and
+the projective class applies general projective transformations, which are the
+most general type of transformation supported by ALE.  
+
+
The Euclidean class is most appropriate for use with scanners and as a first
+pass for projective transformations.  The projective class is most appropriate
+for use with cameras.  
+
+
Except when capturing flat scenes, ALE does not correct for perspective
+changes, so movement of cameras should ideally be constrained so that no large
+translations occur.
+
+
Transformation Class Options

+
+
+--translation     Only adjust the position of images
+--euclidean       Adjust the position and orientation of images [default]
+--projective      Use projective transformations.  Best quality, but slow.
+

+
+
Transformation data file options

+
+Transformations used in alignment can be loaded from a file or saved to a file.
+This can be useful when performing alignment in several passes, or when
+refining rendering options.
+
+
Note that projective transformation data saved to a file cannot be used to
+initialize other transformation types.  
+
+
+--trans-load=x    Load initial transformation settings from file x
+--trans-save=x    Save final transformation data in file x
+

+
+
Alignment following

+
+When frames are more closely aligned with adjacent frames in the sequence than
+they are with the first frame in the sequence, alignment success can be
+improved by specifying the --follow option.  This option can be effective even
+when initial alignment information is loaded from a file.
+
+
+--identity        Frames align closely with the original frame.  [default]
+--follow          Frames align closely with their immediate predecessor.

ALE 0.5.1 User Manual

+
+
Purpose

+
+
This page summarizes ALE program operation and command-line usage.  
+
+
Other manual pages in this section describe rendering and alignment.
+
+
For more information on ALE, see the ALE Home Page.
+
+
Program Operation and Usage

+
+
Parameter Meta-syntax

+
+
+
+
+
+
+
+
+
+
+
+
+
 <foo>A required parameter called foo.
[<foo>]An optional parameter called foo.
+
[<foo>]*Zero or more parameters foo.
+

+
+
Command-line syntax for Version Information

+
+
The following command-line invocation can be used to print version
+information and build options:
+
+
ale --version

+
+The following is sample output from this invocation:
+
+
+ALE Version:      0.5.1
+File handler:     ImageMagick
+Bits per channel: 8
+

+
+The above output indicates that the ALE version is 0.5.1, that ImageMagick is
+being used to handle image files, and that a 24-bit color space is being used.
+
+
Command-line syntax for Help Output

+
+When invoked with no options, or options detected as incorrect, ALE outputs a 
+help message specifying command-line usage and available options.  The following
+is a sample invocation:
+
+
ale

+
+
Command-line syntax for Image Processing

+
+
The following is the normal command-line invocation for ALE, and is used to
+process a series of frames into an output file:
+
+
ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>

+
+
The original-frame parameter, and each supplemental-frame parameter, should
+match the filename of an image file.  Output will be written to the output file
+specified.  
+
+
Depending on compile options, the file handler used may be ImageMagick or an
+internal PPM file handler (use the --version flag to check this).  When
+ImageMagick is used for file handling, input files can be any of the types that
+ImageMagick can handle, and the output file type should be specified by file
+extension.  The internal PPM file handler can be used to read and write PPM
+files only.  However, on many platforms, ImageMagick's command line utilties can be used to
+convert between PPM and other file formats.  
+
+
Options are outlined in the rendering and alignment subsections.

ALE Rendering

+
+Rendering determines how an output image is constructed from a series of
+aligned input frames.  The incremental renderers, merging and drizzling, update
+the output image after reading each new frame from the series, whereas the
+non-incremental renderers wait until the last frame has been loaded to produce
+output.  More than one renderer can be involved in producing the final output image.
+Available rendering options are outlined below.
+
+
Merging

+
+Merging, the default incremental renderer, works most effectively on images
+that have no large changes in scale (e.g. camera zooming).  Since it uses
+bilinear interpolation, output images are approximately convolved with the
+triangle, or Bartlett, filter, and may appear to have reduced contrast and
+resolution in comparison with other renderers.
+
+
Drizzling

+
+The drizzling renderer is an incremental renderer that can usually produce
+better images than merging, but it works most effectively with devices having
+very little blur and optical distortion.  Devices sampling very small angles of
+the scene at each pixel are ideal; hence, if very fine staircase aliasing is
+visible in the input frames, drizzling should work very well.  (For creation of
+higher resolution images with drizzling, use also the --scale option described
+below.)
+
+
+--drizzle-diam=x  Drizzle with input pixel diameter x (where 0 < x <= 1).
+--drizzle-only    If drizzling, output black for pixels with no drizzle data.
+

+
+
For more information about drizzling, see the paper by Richard Hook and
+Andrew Fruchter, "Variable-Pixel Linear Combination", or the following URL:
+
+
http://www.cv.nrao.edu/adass/adassVI/hookr.html
+
+
High-frequency enhancement

+
+
This renderer uses an unsharp mask to enhance the contrast of high
+frequencies.  It can be used to compensate for systematic blurriness introduced
+by merging, drizzling, or the image capture device.  However, better results
+will generally be achievable by using a separate postprocessing tool, such as
+the GIMP or CinePaint (formerly called Film
+GIMP).  In addition to the built-in unsharp mask, the GIMP can make use of
+Ernest Lippe's refocus plugin.
+
+
+--hf-enhance=x    Enhance high frequency details by factor x.  (0.0 is default)
+

+
+
Irani-Peleg iterative image reconstruction

+
+This renderer is by far the most general, and can be used to compensate for
+blurring introduced by the image capture device.  In order to use it most
+effectively, an approximation of the projection function for the capture device
+should be known.  Two general classes of projection functions are supported: box
+filters and custom filters.
+
+
If rendering with the box filter option, manual experimentation can be used
+to find a diameter that works well.  Alternatively, ALE includes a script that
+calibrates custom filters for devices, based on images captured from known
+scenes.
+
+
Two custom filter options are included: one for the IBM PC Camera Pro
+(XVP610) in 320x240 mode, and one for interactive filter specification.
+
+
Note that this option can take a long time to produce output, especially on
+large images.  If incremental output is enabled (see below), output is written after
+each iteration is complete.  Using more iterations will generally improve
+output, up to the point of convergence, when additional iterations have no
+effect.  A dot is displayed to indicate the completion of each iteration.
+
+
+--ip <d> <i>      Solve for a box filter with diameter <d> over <i> iterations.
+--ipc <c> <i>     Solve for device config <c> over <i> iterations.
+

+
+The available device configurations are as follows:
+
+
+xvp610_320x240
+stdin
+

+
+

+Peleg, see their paper, "Improving Resolution by Image Registration", at
+
+
ftp://ftp.wisdom.weizmann.ac.il/pub/irani/PAPERS/SR_CVGIP91.pdf
+
+
Scale factor

+
+Rendering with a larger scale factor causes internal data structures to store
+more information, resulting in image output of the specified larger scale.
+Larger scales can improve alignment precision and output image quality, but can
+also increase alignment and rendering times.
+
+
+--scale=x         Scale images by the factor x (where x is at least 1.0)
+

+
+
Image extents

+
+The --extend option records pixel data that falls outside of the region of the
+first frame in the sequence.  This can be useful for providing additional
+alignment constraints or creating panoramic image mosaics.  (See also the
+description of the --follow option in the alignment
+section.)
+
+
+--extend          Increase image extents to accommodate all pixel data.
+--no-extend       Don't increase extents; crop to original frame. [default]
+

+
+
Incremental output

+
+By default, the output file is written every time a renderer completes an
+update cycle.  In order to suppress output until the final image is rendered,
+specify the --no-inc option.
+
+
+--inc             Produce incremental output.  [default]
+--no-inc          Don't produce incremental output.
+

+
+
Pixel replacement

+
+
When using the merging renderer, --replace indicates that each new frame
+should replace the corresponding region of the rendering, instead of being
+merged with data from previous frames.  This option was originally suggested by
+Jeff Treece for use in stabilization of video streams.  His approach to
+stabilization is outlined below.
+
+
Video Stabilization

+
+
If the files
+
+
0.ppm, 1.ppm, ..., 9.ppm

+
+represent frames from an unstabilized video stream, then the following sequence
+of commands may result in a stabilized sequence:
+
+
+ale --replace         0.ppm 1.ppm 1.stable.ppm
+ale --replace  1.stable.ppm 2.ppm 2.stable.ppm
+ale --replace  2.stable.ppm 3.ppm 3.stable.ppm
+.
+.
+.
+ale --replace  8.stable.ppm 9.ppm 9.stable.ppm
+

+
+
The resulting stabilized sequence would be:
+
+
0.ppm, 1.stable.ppm, 2.stable.ppm, ..., 9.stable.ppm

+
+
Option Syntax

+
+
+--replace         Replace overlapping areas rather than merging.
+--no-replace      Do not replace.  [default]

+
Error Functions

+
+
Error functions are used to determine whether a transformation is "good" or
+not, and in particular, whether one transformation is better or worse than
+another.  In particular, a smaller error indicates a better transformation.
+
+
+
+
ALE defines error functions for each pixel of the accumulated image, and
+also a comprehensive error function that summarizes the error over all 
+pixels.  
+
+
Pre-Alignment Exposure Registration

+
+
When exposure registration is enabled, ALE performs an exposure registration
+step prior to alignment.  The resulting values are dependent on the initial
+alignment (this can be either the default initial alignment or an alignment
+loaded from a transformation data file).  See the source code for details.
+
+
Per-Pixel Error Functions

+
+
+
+
+
The per-pixel error function for pixel (i, j) in the accumulated
+image A, frame B, and transformation T, is:
+
+

+
+p(i, j, A, B, T) = Abs( A(i, j) - B(T_inverse(i, j)) )metric_exponent
+

+

+
+
where Abs() is the absolute value function and B(T_inverse(i,
+j)) is determined by bilinear interpolation.  If not specified by the
+--metric option, metric_exponent defaults to 2.0 for ALE versions 0.1.0
+and later, or 1.0 for version 0.0.0.
+
+
For coordinates where B(T_inverse(i, j)) is not defined, the error is zero.
+(Feedback from Angelo Pesce led to clarification of this point.)
+
+
In addition to the per-pixel error function, a per-pixel maximum error
+estimator is calculated, as follows:
+
+

+
+p_max(i, j, A, B, T) = Max( A(i, j), B(T_inverse(i, j)) )metric_exponent
+

+

+
+
For coordinates where B(T_inverse(i, j)) is not defined, the maximum error
+estimator is zero.  (Feedback from Angelo Pesce led to clarification of this
+point.)
+
+
+
Comprehensive Error Functions

+
+There are two varieties of comprehensive error function used by ALE: an
+exhaustive error function and, in versions 0.4.3 and later,  a
+Monte Carlo error function.  Whereas the exhaustive function
+evaluates the error for each pixel in the accumulated image, the Monte
+Carlo function evaluates only a subset of pixels.  
+
If we consider Sum[] to provide the sum over whatever
+subset of pixels we are sampling (including possibly the set of all pixels), then
+the comprehensive error function, for accumulated image A, frame
+B, and transformation T, is:
+
+

+
+E(A, B, T) = (Sum [ p(i, j, A, B, T) ] / Sum [ p_max(i, j, A, B, T) ])(1/metric_exponent)
+

Monte Carlo Error Function

+
+Monte Carlo alignment can decrease the time required to align large images,
+since performing coordinate transformations and memory accesses at every pixel
+can be expensive.  Sections in this page describe the motivation for Monte
+Carlo alignment, the ratio calculations used, the sampling algorithm, cache
+behavior for the algorithm, randomization approaches, typical deviations from
+the specified ratios, special handling of level-of-detail, and practical
+observations regarding the use of Monte Carlo alignment.
+
+
Motivation

+
+Performing large numbers of coordinate transformations and memory accesses in
+order to determine alignment error can be computationally expensive.  One
+approach to mitigating this expense is to use reduced level-of-detail.
+However, using reduced level-of-detail can also reduce alignment precision.  In
+particular, reducing the level of detail by a factor of two can make impossible
+the task of precisely aligning a horizontal line one pixel high.  However, if
+just a few pixels from the line are sampled at full detail, exact alignment is
+possible.
+
+
Ratio Calculations

+
+
In Monte Carlo alignment, a ratio 
+
+

+s = (expected # of pixel
+samples) / (# of total pixels in the accumulated image)
+

+
+is specified.  From this ratio, a new ratio 
+
+

+u = (expected # of unsampled pixels) / (expected # of sampled pixels)
+

+
+is calculated.  Pixels are sampled in such a manner that u is
+approximately satisified.  
+
+
At this stage, the region of overlap with the new frame is not considered.
+With a limited area of overlap, the number of actual samples contributing to
+the final error value will typically be reduced proportionally.  (Angelo Pesce
+has pointed out that better approaches may be possible, wherein explicit
+calculation of overlapping areas reduces the number of coordinate
+transformations performed.)
+
+
Sampling Algorithm

+
+
Pixels are considered in order of index, where the accumulated image pixel
+at position (i, j) is numbered with an index (i * width + j).
+In order of index, we skip and sample pixels in such a manner that the
+expected size of a run of consecutive skipped pixels preceding a sampled pixel
+is u.  We select the size of each run of consecutive skipped pixels as
+follows:
+
+
If 2 * u is an integer, then we draw uniformly from integer values in
+the interval [0,2u].  If it is not an integer, then we draw from integer values in
+the interval [0,2u + 1] in such a manner that integer values in
+[0,2u] are equally likely to be chosen.  (There is only one probability
+distribution of this kind that satisfies the expected value u.  Version
+0.4.3 deviates slightly from this distribution, and so a deviation in the
+expected value of s occurs, as outlined in this table.  This problem is fixed in version 0.4.4.)
+
+
(Also, see the section below on interaction with level-of-detail.)
+
+
Cache behavior

+
+
Since indices are monotonically increasing in memory address, this approach
+to sampling may make effective use of memory cache where other approaches (e.g.
+repeated random draws from the entire index space) would not.  
+
+
Randomization

+
+ALE versions 0.4.7 and earlier do not reseed the pseudorandom number generator,
+and so a new random subset is selected every time the error function is
+evaluated.  Hence, as more or fewer of the pixels critical to alignment are
+sampled, the reported alignment can worsen or improve even in the absence of
+any change in transformation.
+
+
With this approach, since many transformations are inspected during the
+alignment of any given frame, it is likely, especially with greater precision
+of alignment, that some measured differences between transformations are due to
+a difference in sample sets rather than a difference in alignment accuracy.
+
+
By reseeding the pseudorandom number generator, ALE versions 0.4.8 and later
+instead use a consistent set of pixels from the accumulated image when
+comparing two transformations.  Tests sampling 3% of pixels from a set of
+320x240 frames indicate that this approach improves alignment.
+
+
Sampling characteristics

+
+For an image with 100,000 pixels and specified
+s in the interval [0.005,0.995], ALE's sampling method results in
+a ratio s within 0.000003 of the specified s.  This number 
+improves with image size.  These results are outlined in the table linked
+above.  However, note that s only represents an expected value, and the actual number
+of sampled pixels may vary by more than the numbers given here.
+
+
Interaction with level-of-detail

+
+
When reduced level-of-detail is used, the number of reduced-detail pixels
+sampled is taken to be a percentage of the total number of pixels in the
+full-detail image, rather than as a percentage of the total number of pixels in
+the reduced-detail image.  (When this fraction of pixels in the full-detail
+image is more than the number of reduced-detail pixels available, all
+reduced-detail pixels are used.)  This may improve the likelihood of successful
+alignment, but may also add overhead to the alignment process.
+
+
Use of Monte Carlo Alignment

+
+
  If it is not known in advance what settings will work well for a series of
+frames, it may be desirable to begin by sampling a small percentage of pixels,
+saving the results of alignment, and then, if the output suggests that proper
+alignment is occuring, performing more precise alignment with a larger
+percentage of pixels on later passes, using smaller perturbation upper bounds.
+If alignment problems occur on the first pass, the percentage of pixels can be
+increased and alignment performed again.

Alignment

+
+ALE aligns each supplemental frame, in sequence, with the merged rendering
+representing all previous frames.  This page outlines the three supported
+transformation classes, the algorithm used for alignment, and the properties of
+the alignment algorithm.  Following this is a discussion of practical use of
+alignment options, including alignment classes and alignment in the case of
+extended renderings.
+
+
Transformations

+
+
ALE offers three classes of transformations: 

+
+
+
+
+
+
Translationsintroduced in version 0.0.0
Euclidean transformations (excluding reflections)introduced in version 0.1.0
Projective transformationsintroduced in version 0.2.0

+
+
+
+
Algorithm

+
+
Alignment proceeds by a deterministic search, beginning with an initial
+transformation and modifying this transformation through a series of
+perturbations.
+
+
The initial transformation may be loaded from a file or selected by default.
+The default initial transformation is either the identity transformation or
+(when the --follow option is specified) the most recently merged
+frame's final alignment.  (Note that changes in release 0.5.0 are not reflected
+here; these changes affect the interaction of the --follow and --trans-load
+flags.)
+
+
Once the initial transformation is determined, an initial perturbation
+amount is selected, and represents the step size by which each of the
+transformation parameters are changed.  In translational or Euclidean
+alignment, the perturbation amount is applied to translation -- in units of
+pixels on the two image axes -- and rotation -- in units of degrees about the
+image center.  (In version 0.4.8 and later, an additional configurable upper
+bound constrains rotational perturbation separately, preventing, e.g., a
+360 degree perturbation of rotation.)  In the case of projective alignment, the
+perturbation amount is applied to the position of the corners of the projected
+quadrilateral in units of pixels, where the projection is from the boundary
+of the supplemental image into the coordinate system of the accumulated image.
+
+
If possible, transformation parameters are changed to decrease the error between the two images being
+aligned.  The perturbation amount is halved whenever it is determined that no
+parameter change of this size improves the alignment of the images.  A lower
+bound on the perturbation amount determines when the alignment is complete.
+
+
The order in which parameters are considered for change is specified in the
+source code, and has the following property: No modified parameter is
+considered for further change until all other parameters have been considered.
+A consequence of this property is that parameters are always considered in a
+fixed (round robin) order.
+
+
When multiple levels of detail are used, the error may be calculated on
+images with a reduced level of detail.  ALE versions 0.1.1 through 0.4.7 use a
+level of detail twice as fine as the perturbation amount for perturbation
+amounts larger than two, and full detail otherwise.  Later versions default to
+this behavior, but can be configured differently.  Earlier versions do not use
+reduced levels of detail.
+
+
Properties

+
+
Several assumptions were made throughout the design and testing of the
+algorithm outlined above.  These assumptions are outlined below.
+
+
The algorithm is based on a hill-climbing approach, which requires that any
+local minimum reachable from the starting point by traveling a path of
+decreasing error is also a global minimum (or, in this case, the correct
+alignment).  While it is possible that the algorithm outlined above succeeds in
+some cases for which hill-climbing fails, it is still susceptible to entrapment
+in local minima.
+
+
As outlined above, depending on program options, transformation parameters
+may be changed by perturbations of several units (degrees or pixels) early in
+the alignment process.  As long as no change of this magnitude moves the
+transformation out of the 'bowl' in which the minimum error -- and hence
+correct alignment -- lies, this is not a problem.  However, it might break in
+some cases where a hill-climbing approach would succeed.  (Notably, simulated
+annealing suffers from a similar problem, and it seems likely that a case could
+be constructed in such a way that the algorithm outlined above -- like
+simulated annealing -- could, contrarily, succeed where hill-climbing fails.)
+
+
Finally, the use of reduced level-of-detail relies on a high signal-to-noise
+ratio at low frequencies.  Fortunately, this assumption seems to generally
+hold, but camera defects or radio interference could violate the assumption,
+possibly resulting in misalignment.
+
+
Use of Alignment Classes

+
+
ALE is likely to be most useful when corresponding regions of different
+frames can be aligned by one of the available alignment classes.
+
+
As described by Steve Mann in his work on Video Orbits, the projective
+transformation offers particular versatility for camera imaging of (ideal
+Lambertian) flat scenes.  In this case, any change in camera position and
+orientation can be corrected as long as points always have a defined projection
+onto the rendering plane (for which ALE uses the base of the pyramid
+R1).
+
+
In camera imaging of scenes with depth, correction for orientation is almost
+the same as for flat scenes, since, if focus and lens distortion is ignored, a
+scene with depth is indistinguishable from a flat scene from the perspective of
+a camera whose position is fixed.
+
+
For sequences of camera images with small changes in position or
+orientation, the projective transformations for alignment may closely
+approximate Euclidean transformations; in this case, using Euclidean
+transformations may achieve similar results and may require less time for
+alignment, since there are fewer parameters to tweak (three parameters
+instead of eight).
+
+
In the case of flatbed scanners that preserve the relative height and width
+of scans, any change in the position or orientation of flat objects can be
+corrected using the Euclidean alignment class.

+
+
If a flatbed scanner does not preserve relative height and width, but does
+preserve straight lines, then any change in the position or orientation of flat
+objects can be corrected with the projective alignment class.
+
+
However, even if a transformation is within the alignment class used, the
+alignment algorithm may still be unable to approximate it.
+
+
Alignment in the case of Extended Renderings

+
+
By using the --extend flag, ALE can be used to create image mosaics spanning
+a spatial region larger than that represented by any single image in the frame
+sequence.  In these cases, if adjacent frames in the sequence tend to be more
+closely aligned with each other than they are with the original frame, it may
+be helpful to also use the --follow flag as a hint to the alignment algorithm.

Drizzling Renderer

+
+
ALE versions 0.4.1 and later implement a drizzling algorithm based on that
+outlined in research by Richard Hook and Andrew Fruchter.1  
+
+
Algorithm

+
+
In the drizzle rendering method, pixels from source images are associated
+with a square region of given radius in the source image coordinate system.
+Similarly, each pixel in the accumulated image, or target image, is associated
+with a square region, such that each square region coincides with its neighbors
+exactly at its edges.  The source regions are then transformed according to the
+known alignment between source and target, and the regions from all transformed
+source images are combined to form the target image, where each source pixel
+region contributes to each target pixel region linearly with the area of
+overlap between the regions (as calculated in the target coordinate system).
+
+
ALE uses an approximation to the above approach, wherein the area of overlap
+is calculated in the coordinates of the source image and then multiplied by a
+factor approximating any difference in scale between the source and target
+images; for the purpose of these calculations, the region of the target pixel
+is approximated by a rectangle in the source coordinate system having all sides
+parallel to the source image coordinate axes.
+
+
Properties

+
+
Assuming small drizzling radius, drizzling is approximately the same as
+convolution of discrete pixel data with a box filter having the same radius as
+the chosen drizzling radius.  Given the box filter approximation, jittering
+assumption, point sampling, and sufficiently small radius, drizzling should
+provide an acceptable approximation of T.  Until this is proven,
+however, this result should be considered unreliable.
+
+
+
1 More information on drizzling can be found in the paper by Hook and Fruchter,
+"Variable-Pixel Linear Combination", published in vol. 125 of the ASP
+Conference Series (eds. Gareth Hunt and H. E. Payne).  This paper was also
+published on-line at:

USM Renderer

+
+
The Unsharp Mask Renderer is a built-in post-processing step based on the
+unsharp mask technique, which has been used to enhance high frequencies since
+the days of photographic plate processing (see, for example, this
+page).  This renderer acts after all other rendering steps have completed,
+except for Irani-Peleg rendering, which occurs afterward.
+
+
Properties

+
+
Given a sequence of images that satisfy all predicates for merging (or
+drizzling) except point sampling; given a known linear PSF; and given only
+translations between frames, the result of merging (or drizzling) will be an
+acceptable approximation of T convolved with the PSF.  This does not
+imply that deconvolution of this result will be an acceptable approximation of
+T, however, since frequencies with low response may be reconstructed
+with poor fidelity due to reduced precision.  We use the low-response
+approximation to ignore these frequencies.  Assuming the USM approximation, the
+remaining frequencies are reconstructed to form an acceptable approximation of
+T.  (Since this doesn't really constitute a proof, the results should be
+considered unreliable.)

ALE Version 0.6.0 Technical Description  

+
+
Abstract

+
+
ALE combines a series of input frames into a single output image possibly
+having:

+
+
    
+
  • Reduced noise.
+
  • Reduced aliasing.
+
  • Increased tonal resolution.
+
  • Increased spatial resolution.
+
  • Increased spatial extents.
+

+
+
This page discusses related work, models of program input, renderers used by
+ALE, the alignment algorithm used, an overview of the structure of the
+program, and examples for which the above output image characteristics are
+satisfied.

+
+
ALE's approach to exposure registration and certainty-based rendering is not
+discussed in the current version of this document.  See the source code for
+implementation details.
+
+
Note: This document uses HTML 4 character entities.  Sigma is 'Σ'; summation is '∑'.

+
+
Related Work

+
+
The drizzling renderer used in ALE is based on
+Richard Hook and Andrew Fruchter's drizzling technique.
+
+
Steve Mann's discussions (e.g. here and here) of increased spatial extents, projective
+transformations, image processing on linear data, and weighting by certainty
+functions, have influenced features incorporated by ALE.  
+
+
ALE incorporates an iterative solver based on Michal Irani and Shmuel
+Peleg's iterative deblurring and super-resolution technique (see here).

+
+

Projective transformations

+
+
A projective transformation is a transformation that maps lines to
+lines.  For more details, see:
+
+

+Heckbert, Paul.  "Projective Mappings for Image Warping."  Excerpted from his
+Master's Thesis (UC Berkeley, 1989).  1995.  http://www.cs.cmu.edu/afs/cs/project/classes-ph/862.95/www/notes/proj.ps
+

+
+
Projective Snapshots

+
+
A projective snapshot is defined as an n-tuple consisting of:

+
+
    
+
  • A continuous image Σ.
+
  • A projective transformation q with restricted domain, such that composite(Σ, q) ∈ CC
+
  • A function d: CC → DD.
+

+
+
Projective Input Frame Sequences

+
+
For positive integer N, a sequence of projective snapshots {
+P1, P2, …, PN }, defined by the
+n-tuples { Pj = (Σj, qj,
+dj) }, is a projective input frame sequence if, for all
+j and j', Σj = Σj'.
+
+
The first frame in the sequence of input frames is called the original
+frame, and subsequent frames are called supplemental frames.
+
+
Construction of Projective Input Frame Sequences from Camera Input Frame Sequences

+
+
Given a camera input frame sequence { Kj = (S, Vj,
+dj) }, if there exists a continuous image Σ and a
+sequence { qj } of projective transformations with restricted 
+domain such that, for all j, Vj(S) =
+qj(Σ), then this camera input frame sequence admits a
+corresponding projective input frame sequence { Pj = (Σ,
+qj, dj) }.
+
+
Informally, two cases where such construction is possible for an ideal
+pinhole camera are:
+
+
    
+
  • A sequence of frames taken from a fixed position in space, but with variable
+orientation.
+
  • A sequence of frames depicting a single flat, diffuse surface, taken from 
+arbitrary positions and orientations.
+

+
+
For more information about the properties of projective transformations, 
+see the first of Steve Mann's papers referenced in the Related Work section above.
+
+
Projective Renderer without Extension

+
+
For a projective input frame sequence { Pj = (Σ,
+qj, dj) }, a projective renderer without
+extension is an algorithm that outputs a discrete image approximation of
+composite(Σ, q1).  The assumptions used in calculating the approximation
+vary across rendering methods.
+
+
Projective Renderer with Extension

+
+
For a projective input frame sequence { Pj = (Σ,
+qj, dj) }, a projective rendering method with
+extension is an algorithm that outputs a discrete image approximation of
+composite(Σ', q1'), where q1' extends
+the domain of q1 so that its range is a superset of the
+domain of Σ, and Σ' extends Σ to match
+the range of q1'.  The assumptions used in calculating the
+approximation vary across rendering methods.
+
+
+
+
Renderers

+
+
+
Extension

+
+
All renderers can be used with or without extension (according to whether
+the --extend flag is used).  The target image for approximation (either
+composite(Σ, q1) or composite(Σ',
+q1')) is generically called T.
+
+
Renderer Types

+
+
Renderers can be of incremental or non-incremental type.  Incremental
+renderers update the rendering as each new frame is loaded, while
+non-incremental renderers update the rendering only after all frames have been
+loaded.

+
+
Incremental renderers contain two data structures that are updated with each
+new frame: an accumulated image A with elements Ax, y
+and the associated weight array W with elements Wx, y.
+The accumulated image stores the current rendering result, while the weight
+array stores information about contributions to each accumulated image pixel.
+
+
Renderer Details

+
+These pages offer detailed descriptions of renderers.
+
+
+
+
Rendering Predicates

+
+
The following table lists predicates which may be useful in determining
+whether the discrete-image output of a rendering method approximates T.
+The section following this lists, for each renderer, a collection of predicates
+which should result in T being approximated.

Predicate
+Explanation
AlignmentThe projective input frame transformations qj are known.
TranslationAll projective input frame transformations qj are 
+translations.
Point sampling(∀j) (∀x ∈ Domain[qj]) (dj(composite(T, qj))(x) = composite(T, qj)(x)).
+
Box Filter ApproximationAn acceptable discrete approximation of T can be achieved by
+partitioning it into a square grid and representing each square region by its
+mean value.
+
Jittering Assumption 1The average of several point samples drawn uniformly from a region of
+T is an acceptable approximation for the mean value of the region.
+
Jittering Assumption 2Each region in T corresponding to an output pixel has been sampled several
+times at points drawn uniformly from the region.
+
Small radiusThe radius parameter used for drizzling is chosen to be sufficiently small.
+
Barlett filter approximationConvolution of T with a Bartlett (aka triangle) filter remains an
+acceptable approximation of T.
+
Linear PSF onlyThere is no non-linear PSF component.
+
USM approximationThe Unsharp Mask technique provides an acceptable approximation of the
+inverse convolution for the given linear point-spread function.
+
Correct PSFThe behavior of dj is equivalent to convolution with the
+given point-spread functions.
+
Low Response ApproximationFrequencies to which dj has low response need not be
+accurately reconstructed in the program output.  
+
ConvergenceThe Irani-Peleg technique converges to the desired output for the given
+input sequence.  This condition is proven for special cases in the source
+paper.
+

+

+
+
Rendering Predicates by Renderer

+
+
For each renderer, the following table gives a collection of rendering
+predicates that should result in rendered output being an acceptable
+approximation of T.  Note that renderers may produce acceptable output
+even when these predicates are not satisfied.  Justification for the entries in
+this table should appear in the detailed descriptions; if this is not the case,
+then the values given should be considered unreliable.

Space Complexity

+
+Image storage space in memory for all renderers without extension is
+O(1) in the number of input frames and O(n) in the number of pixels per
+input frame.  The worst-case image storage space in memory for all renderers
+with extension is O(n) in the size of program input.
+
+
Alignment Algorithm

+
+Details on the alignment algorithm used in ALE are here.
+
+
Program Structure

+
+
First, a merging renderer is instantiated.  Then,
+program flags are used to determine what other renderers should be
+instantiated.
+
+
An iterative loop supplies to the renderers each of the frames in sequence,
+beginning with the original frame.  The drizzling and
+merging renderers are incremental renderers, and
+immediately update their renderings with each new frame, while the USM and Irani-Peleg renderers do not act until the final frame
+has been received.
+
+
In the case of the incremental renderers, the original frame is used without
+transformation, and each supplemental frame is transformed according to the
+results of the alignment algorithm, which aligns each
+new frame with the current rendering of the merging
+renderer.
+
+
Once all frames have been aligned and merged, non-incremental renderers
+produce renderings based on input frames, alignment information, and the output
+of other renderers.

+
+
Examples

+
+Sections below outline examples of cases in which output images satisfy various criteria.
+
+
For a projective input frame sequence { Pk = (Σ, q,
+dk) }, these examples use the shorthand 
+
+
I = composite(Σ, q)

+
+and 
+
+
Dk = dk(I).

+
+
Reduced Noise

+
+
Assume a projective input frame sequence { Pk } of K frames, defined
+by n-tuples { Pk = (Σ, q, dk) }, such that
+(∃a > 0) (∀x ∈ Domain[q]) (∀y ∈ {R, G, B})
+(I(x)y > a/2) and, for one
+such a, (∀x) (∀y) (Dk(x)y =
+I(x)y + nk,x,y), where nk,x,y are
+i.i.d. additive noise terms having uniform distribution over the interval
+(-a/2, a/2).  
+
+
In this case, rendering input frames by merging or drizzling averages the
+additive noise terms of the input images to produce an output additive noise
+term; when K ≥ 2, this output noise has a smaller expected absolute value than that of
+any given input noise term.
+ 
+
To prove this, first observe that rendered output image O (for drizzling or merging) averages the K inputs with
+equal weight:
+
+
O(x)y = ∑k (Dk(x)y / K)

+
+Substituting for Dk:
+
+
O(x)y = ∑k [(I(x)y + nk,x,y) / K]

+
+Moving the constant outside of the sum:
+
+
O(x)y = (I(x)y / K) * K + ∑k (nk,x,y / K)

+
O(x)y = I(x)y + ∑k (nk,x,y / K)

+
+The last term in the equation above is the noise term for the output image.  Leaving location
+and channel implicit, the expected absolute value for this term is:
+
+
Eout = E[|∑k (nk / K)|]

+
+Since there is nonzero probability that both strictly negative and strictly positive terms appear in the sum, this gives rise to the strict inequality:
+
+
Eout < E[∑k |nk / K|]

+
+By linearity of expectation, this is equivalent to:
+
+
Eout < ∑k E[|nk / K|]

+
Eout < ∑k E[|nk|] / K

+
+Since the input noise distributions are identical, this reduces to:
+
+
Eout < Ein * K / K

+
Eout < Ein

+
+where Ein = E[|nk|] for any choice of k.
+
+
Reduced Aliasing

+
+Assume that an image has been sampled at the highest frequency to which the
+sensors respond (i.e., half of the Nyquist frequency), resulting in aliasing,
+and that four such images are available, dithered (i.e., in this case,
+translated) so that the collection of samples from all images forms a regular
+grid with twice the sampling rate of the original image.  Rendering these four
+images with correct alignment into an output image having the same dimensions
+as this grid results in an image with no aliased frequencies.
+
+
Increased Tonal Resolution

+
+
Assume a projective input frame sequence { Pk } of
+K frames, defined by n-tuples { Pk = (Σ, q,
+dk) }, such that components of I assume a real value in
+the interval [0, 1] and (∀ x, y, k)
+(Probability[Dk(x)y = 1] = 1 - Probability[Dk(x)y = 0] = I(x)y]).
+
+
Since the transformations of all frames are identical, rendering with
+merging or drizzling averages the values for each pixel Dk(x)
+over all values of k.  Since the expected value of Dk(x)
+is equal to I(x), the expected value of the corresponding pixel in the rendered
+output is always equal to I(x).  However, the probability of obtaining a value
+within a small neighborhood of I(x) is generally not high for small numbers of 
+frames.
+
+
As the number of frames increases, however, the probability of
+obtaining a value within a neighborhood of any given size approaches 1.  Hence,
+arbitrarily high tonal resolution can be achieved with arbitrarily small (but
+non-zero) likelihood of error.  The exact probability can be determined
+according to the binomial distribution.
+
+
(The above constitutes an outline of a proof, but there may be holes in it.)
+
+
Increased Spatial Resolution

+
+The reduced aliasing example, above, serves also as an example of increased
+spatial resolution.
+
+
Increased Spatial Extents

+
+
Assume a projective input frame sequence such that each snapshot can be
+associated with a point in the scene invisible from that snapshot, but visible
+from some other snapshot.
+
+
In this case, for every snapshot in the input sequence, the output rendering
+will include at least one point not present in that snapshot.

Irani-Peleg Renderer

+
+
ALE implements an iterative image reconstruction algorithm based on Michal
+Irani and Shmuel Peleg's paper "Improving Resolution by Image Registration",
+published in Graphical Models and Image Processing, Vol. 53, No. 3, May,
+pp. 231-239, 1991, or available at:
+
+
http://www.wisdom.weizmann.ac.il/~irani/abstracts/superResolution.html
+
+
This algorithm iteratively performs two steps: first, an
+approximation of T is projected, based on a filter approximating
+dj, and data collected during alignment, to create a set of simulated input frames;
+second, the per-pixel error -- between these simulated input frames and the
+actual input frames -- is calculated, backprojected, and subtracted from the
+approximation of T, resulting in a new approximation of T.
+
+
Initial Image Approximation

+
+
ALE uses the results of previous rendering steps as the initial image
+approximation.

+
+
Projection and Back-projection filters

+
+ALE provides command-line options for selecting forward-projection filters,
+including box filters (release 0.4.2 and later) and custom filters (release
+0.4.7 and later).  The back-projection filters are constructed from the
+forward-projection filters in such a way that condition (9) from Theorem 4.1
+in the source paper is satisfied.
+
+
Transformation details

+
+
ALE's method of transforming pixel areas between coordinate systems
+approximates transformed pixel boundaries with axis-aligned rectangular
+regions.  Since boundaries are transformed into the coordinate systems of the
+input frames, this approximation can be improved by using larger scale factors
+(and hence reducing the size of transformed pixels).

+
+
Multi-level operation

+
+
The following is an edited excerpt from the comment headers for the source
+file d2/render/ipc.h.  For more information about ALE's
+implementation of multi-level operation, see the relevant source files.
+
+

Merging

+
+Merging uses bilinear interpolation to determine each frame's contribution to
+the accumulated image, with each contribution assigned equal weight.  Where
+bilinear interpolation does not define a value, the accumulated image pixel is
+not updated.  Sections below outline the properties of this approach.
+
+
Properties

+
+
Convolution with the Bartlett (triangle) filter as the limiting case

+
+
Assuming predicates for translation and point sampling, bilinear
+interpolation is equivalent to convolution with a Bartlett filter.  Combined
+with the box filter approximation, jittering assumptions, and Bartlett filter
+approximation, the result of merging should be an acceptable approximation of
+T.  This should be proven at some point.  Until then, this result should
+be considered unreliable.
+
+
Density and false local minima

+
+
Informally, the merging method outlined above always updates a dense set
+of pixels in the accumulated image.  In particular, any accumulated image pixel
+whose center falls on a line between updated pixels is also an updated pixel.
+
+
It is conceivable that this property reduces the likelihood of alignment
+failure due to entrapment in local minima; hence, the merging renderer is
+always used as a reference for the alignment
+algorithm.  Except in cases where a large radius is used, drizzling does not share these properties.

+
Alignment

+
+Alignment compares each supplemental frame in the sequence with an intermediate
+rendering known as the reference image.  Based on this comparison, a
+transformation is assigned to the supplemental frame.  Many different
+transformations can be assigned before alignment of the frame is complete.
+
+
Match statistics

+
+The match statistic is a single number indicating how well two frames are
+aligned; this number is used to select or reject transformations during
+alignment.  After alignment is complete, ALE displays the final match
+statistic.  If the value is close to 100%, then the frames are well aligned.
+Very low values can indicate misalignment.  However, even frames that are very
+well aligned do not usually achieve 100% alignment, and, for improving image
+quality, ALE works most effectively when match values are less than 100%.
+
+
Match threshold

+
+A match threshold can be specified; no images with final match statistics
+falling below this threshold will contribute to the final output.
+
+
+--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)
+

+
+
Alignment error metric exponent

+
+The function calculated at each pixel to determine the match statistic is known
+as the alignment error metric, and is of the form (a-b)x.
+The value x is known as the error metric exponent, and is 2 by default.
+Larger numbers usually mean that alignment will be more influenced by smaller
+image features.
+
+
+--metric=x        Set the alignment error metric exponent.       (2 is default)
+

+
+
Alignment Channel Options

+
+In calculating the per-pixel error metric, there are three ways in which ALE
+can handle color channels.  By default, ALE adds the channels before
+calculating the match.  However, ALE can also rely solely on the green color
+channel or use all three channels separately.
+
+
+--align-all       Align images using all color channels
+--align-green     Align images using the green channel
+--align-sum       Align images using a sum of channels [default]
+

+
+
Monte Carlo Alignment

+
+Aligning large images can take a very long time if all pixels are examined in
+determining the match statistic, so it is often desirable to examine a smaller
+number of pixels.  The Monte Carlo alignment option allows this.  The number of
+pixels used is specified as a percentage, and smaller numbers usually mean
+faster, but less precise, alignment.
+
+
+--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
+--no-mc           Align using all pixels.  [default]
+

+
+
Perturbation

+
+Every dot displayed after an input filename indicates a change in perturbation
+size.  The size is initially set to be high, allowing large changes in
+alignment to be evaluated, and is reduced as the locally optimal alignment is
+found for each size.  When this size drops below a specified lower bound, the
+frame is considered to be aligned.
+
+
Perturbation bounds

+
+These options determine the upper and lower bounds for perturbation size.  The
+perturb-upper and perturb-lower bounds apply to rotation (in degrees),
+translation (in pixels), and the movement of the boundaries of a projected
+frame (in pixels).  The rot-upper bound disables rotational perturbation above
+a certain perturbation size (in degrees).  To disable alignment, set
+perturb-upper to zero.
+
+
+--perturb-upper=x Perturbation upper bound in pixels/degrees  (32.0 is default)
+--perturb-lower=x Perturbation lower bound in pixels/degrees  (.125 is default)
+--rot-upper=x     Rotation-specific perturbation upper bound  (32.0 is default)
+

+
+
Level of detail

+
+
Alignment at large perturbation sizes is usually carried out on
+reduced-detail images.  To disable this, set lod-max to
+log2(perturb-upper).
+
+
+--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)
+

+
+
Transformations

+
+The variables used to adjust alignment are called transformations, and map
+points from a source image to a target image.  
+
+
There are three transformation classes that can be used by ALE.  The
+translational class applies only translations to the inputs, changing only the
+position of images; the Euclidean class applies translations and rotations; and
+the projective class applies general projective transformations, which are the
+most general type of transformation supported by ALE.  
+
+
The Euclidean class is most appropriate for use with scanners and as a first
+pass for projective transformations.  The projective class is most appropriate
+for use with cameras.  
+
+
Except when capturing flat scenes, ALE does not correct for perspective
+changes, so movement of cameras should ideally be constrained so that no large
+translations occur.
+
+
Transformation Class Options

+
+
+--translation     Only adjust the position of images
+--euclidean       Adjust the position and orientation of images [default]
+--projective      Use projective transformations.  Best quality, but slow.
+

+
+
Transformation data file options

+
+Transformations used in alignment can be loaded from a file or saved to a file.
+This can be useful when performing alignment in several passes, or when
+refining rendering options.
+
+
Note that projective transformation data saved to a file cannot be used to
+initialize other transformation types.  
+
+
+--trans-load=x    Load initial transformation settings from file x
+--trans-save=x    Save final transformation data in file x
+

+
+
Alignment following

+
+When frames are more closely aligned with adjacent frames in the sequence than
+they are with the first frame in the sequence, alignment success can be
+improved by specifying the --follow option.  This option can be effective even
+when initial alignment information is loaded from a file.
+
+
+--identity        Frames align closely with the original frame.  [default]
+--follow          Frames align closely with their immediate predecessor.

ALE File Output

+
+File output options determine the format in which rendered images are written.
+Depending on the compilation options used, available file output options vary.
+
+
PPM Output

+
+All builds of ALE support PPM output.  PPM can be written in plain (ASCII) or
+raw (binary) format.  If ALE has been built without ImageMagick support, or if
+the file type cannot be automatically determined by file extension, then raw
+PPM output is used by default.
+
+
+--raw             Write raw PPM output
+--plain           Write plain PPM output
+

+
+
Extension-based file type determination

+
+If ALE has been built with ImageMagick support, then the output file type can
+be determined automatically by file extension.  This is the default behavior
+for ImageMagick builds.  The --auto flag explicitly specifies that
+the default behavior should be used.  This flag generates an error on builds
+compiled without ImageMagick support.  
+
+
+--auto            Determine file type automatically
+

+
+
Output Color Depth

+
+Output color depth of 8 or 16 bits of precision per color channel can be specified,
+for 24-bit or 48-bit color, respectively.  
+
+
+--8bpc            Write 8 bit per channel output [default]
+--16bpc           Write 16 bit per channel output

ALE Rendering

+
+Rendering determines how an output image is constructed from a series of
+aligned input frames.  The incremental renderers, merging and drizzling, update
+the output image after reading each new frame from the series, whereas
+non-incremental renderers wait until the last frame has been loaded before
+producing output.  More than one renderer can be involved in producing the
+final output.  Available rendering options are outlined below.
+
+
Merging

+
+Merging, the default incremental renderer, works most effectively on images
+that have no large changes in scale (e.g. camera zooming).  Since it uses
+bilinear interpolation, output images are approximately convolved with the
+triangle, or Bartlett, filter, and may appear to have reduced contrast and
+resolution when compared with the output of other renderers.
+
+
Drizzling

+
+The drizzling renderer is an incremental renderer that can usually produce
+better images than merging, but it works most effectively with devices having
+very little blur and optical distortion.  Devices sampling very small angles of
+the scene at each pixel are ideal; hence, if very fine staircase aliasing is
+visible in the input frames, drizzling should work very well.  (For creation of
+higher resolution images with drizzling, use also the --scale option described
+below.)
+
+
+--drizzle-diam=x  Drizzle with input pixel diameter x (where x > 0)
+--drizzle-only    If drizzling, output black for pixels with no drizzle data.
+

+
+
For more information about drizzling, see the paper by Richard Hook and
+Andrew Fruchter, "Variable-Pixel Linear Combination", or the following URL:
+
+
http://www.cv.nrao.edu/adass/adassVI/hookr.html
+
+
Point-spread Function (PSF)

+
+
Non-incremental renderers use a point-spread function to model the optical
+and electronic properties of the capture device used.  The PSF can be specified
+in terms of a linear and non-linear component.  The non-linear component is
+disabled by default.
+
+
Determining the PSF

+
+
The point-spread function can be approximated through trial-and-error or
+based on known scenes.  ALE includes a script that numerically approximates the
+point-spread function based on images captured from known scenes.  This script
+can be found in the source distribution
+(d2/render/psf/ale-psf-calibrate).
+
+
Device Specification

+
+If a device is known to ALE, then its PSF can be implicitly set with the device
+option.
+
+
+--device <d>      Set the capture device to <d>.
+

+
+Available devices are as follows:
+
+
+xvp610_320x240    IBM PC Camera Pro (XVP610) in 320x240 mode.
+

+
+
PSF specification

+
+
The PSF can also be explicitly specified by using one or both of the psf
+options.  These options have precedence over the device option.
+
+
+--lpsf <p>        Set linear colorspace point-spread function to <p>
+--nlpsf <p>       Set non-linear colorspace point-spread function to <p>
+

+
+Available explicit point-spread functions are as follows:
+
+
+box=<d>           Set the PSF to a box filter with diameter <d>.
+stdin             Specify a custom filter at runtime.
+<p>+<p>           Summation of two functions
+

+
+
Unsharp Mask (USM) Renderer

+
+
This non-incremental renderer uses an unsharp mask to compensate for
+blur introduced by the image capture device.  It is fairly inexpensive
+computationally, but it may not be effective in all cases.  
+
+
+--usm <m>         Apply an unsharp mask with multiplier <m>.
+

+
+
Irani-Peleg iterative solver

+
+
This non-incremental renderer is very general, and attempts to reconstruct the
+original scene based on the captured frames and the PSF.  Unlike the USM
+renderer, it can compensate for blur introduced by the incremental
+renderers, and it may be more effective than the USM renderer in compensating
+for blur introduced by the image capture device.
+
+
Note that this method can take a long time to produce output.  If
+incremental output is enabled (see below), output is written after each
+iteration is complete.  Using more iterations will generally improve output, up
+to the point of convergence, when additional iterations have no effect.  A dot
+is displayed to indicate the completion of each iteration.
+
+
+--ips <i>         Run <i> iterations.
+

+
+
For more information on the iterative backprojection technique of Michal Irani and
+Shmuel Peleg, see their paper, "Improving Resolution by Image Registration", at
+
+
ftp://ftp.wisdom.weizmann.ac.il/pub/irani/PAPERS/SR_CVGIP91.pdf
+
+
Exposure Registration

+
+
By default, ALE adjusts an exposure model to minimize differences in tone
+between frames.  The option --exp-noregister indicates that
+exposure should be assumed uniform across all frames.  In this case, no
+adjustment is performed.

+
+
+--exp-register    Register exposure between frames.  [default]
+--exp-noregister  Assume uniform exposure across all frames.
+

+
+For more information about analyzing and processing images having differing
+exposures, see Steve Mann's comparametric paper, at
+
+
http://wearcam.org/comparam.htm
+
+
Certainty-weighted Rendering

+
+
The exposure model in ALE includes an associated certainty function, which
+quantifies the reliability of sensor measurements.  By default, this function
+is raised to the zeroth power to obtain uniform certainty for all measurements.
+To specify a different certainty exponent, the option --cx can be
+used.
+
+
+--cx <x>          Render with certainty exponent <x>
+--no-cx           Render with uniform certainty.  [default]
+

+
+Note that ALE uses a one-sided certainty function, biased by
+backprojection value, in Irani-Peleg rendering.  In some cases, this approach
+seems to offer better results than the unbiased function used in drizzling and
+merging.  For more information on the certainty weighting approach used by ALE,
+see the ALE source code.  
+
+
For more information on Steve Mann's original approach to certainty-weighted
+rendering, see his comparametric paper, at
+
+
http://wearcam.org/comparam.htm
+
+
Scale factor

+
+Rendering with a larger scale factor causes internal data structures to store
+more information, resulting in image output of the specified larger scale.
+Larger scales can improve alignment precision and output image quality, but can
+also increase alignment and rendering times.
+
+
+--scale=x         Scale images by the factor x (where x is at least 1.0)
+

+
+
Image extents

+
+The --extend option records pixel data that falls outside of the region of the
+first frame in the sequence.  This can be useful for providing additional
+alignment constraints or creating panoramic image mosaics.  (See also the
+description of the --follow option in the alignment
+section.)
+
+
+--extend          Increase image extents to accommodate all pixel data.
+--no-extend       Don't increase extents; crop to original frame. [default]
+

+
+
Incremental output

+
+By default, the output file is written every time a renderer completes an
+update cycle.  In order to suppress output until the final image is rendered,
+specify the --no-inc option.
+
+
+--inc             Produce incremental output.  [default]
+--no-inc          Don't produce incremental output.
+

+
+
Pixel replacement

+
+
When using the merging or drizzling renderer, --replace indicates that each
+new frame should replace the corresponding region of the rendering, instead of
+being averaged with data from previous frames.  This option was originally
+suggested by Jeff Treece for use in stabilization of video streams.  His
+approach to stabilization is outlined below.
+
+
Video Stabilization

+
+
If the files
+
+
0.ppm, 1.ppm, ..., 9.ppm

+
+represent frames from an unstabilized video stream, then the following sequence
+of commands may result in a stabilized sequence:
+
+
+ale --replace         0.ppm 1.ppm 1.stable.ppm
+ale --replace  1.stable.ppm 2.ppm 2.stable.ppm
+ale --replace  2.stable.ppm 3.ppm 3.stable.ppm
+.
+.
+.
+ale --replace  8.stable.ppm 9.ppm 9.stable.ppm
+

+
+
The resulting stabilized sequence would be:
+
+
0.ppm, 1.stable.ppm, 2.stable.ppm, ..., 9.stable.ppm

+
+
Option Syntax

+
+
+--replace         Replace overlapping areas when merging and drizzling.
+--no-replace      Do not replace.  [default]
+

Error

+
+
Error calculations are used to determine whether a transformation is "good"
+or not, and in particular, whether one transformation is better or worse than
+another.  A smaller error indicates a better transformation, from the perspective
+of the alignment algorithm.
+
+
ALE defines an error value for each pixel of the alignment reference image, and also
+comprehensive error, which summarizes the error over all pixels.  
+
+
Pre-Alignment Exposure Registration

+
+
When exposure registration is enabled, ALE performs an exposure registration
+step prior to alignment.  The result of this step is dependent on the initial
+alignment (this can be either the default initial alignment or an alignment
+loaded from a transformation data file).  See the source for more details.
+
+
Per-Pixel Error

+
+
+
+
+
The per-pixel error for pixel (i, j) in the alignment reference
+image A, frame B, and transformation T, is:
+
+

+
+p(i, j, A, B, T) = Abs( A(i, j) - B(T_inverse(i, j)) )metric_exponent
+

+

+
+
where Abs() is the absolute value function and B(T_inverse(i,
+j)) is determined by bilinear interpolation (unless a different interpolant
+is specified using --afilter).  If not specified by the --metric
+option, metric_exponent defaults to 2.
+
+
For coordinates where B(T_inverse(i, j)) is not defined, the error is zero.
+(Feedback from Angelo Pesce led to clarification of this point.)
+
+
In addition to per-pixel error, a per-pixel maximum error
+estimator is calculated, as follows:
+
+

+
+p_max(i, j, A, B, T) = Max( A(i, j), B(T_inverse(i, j)) )metric_exponent
+

+

+
+
For coordinates where B(T_inverse(i, j)) is not defined, the maximum error
+estimator is zero.  (Feedback from Angelo Pesce led to clarification of this
+point.)
+
+
+
Comprehensive Error

+
+
There are two varieties of comprehensive error used by ALE: exhaustive
+error (enabled by --no-mc) and Monte Carlo error (enabled by --mc).
+Whereas the exhaustive approach evaluates the error for each pixel in the
+alignment reference image, the Monte Carlo approach evaluates
+only a subset of pixels.  
+
+
If we consider Sum[] to provide the sum over whatever subset of
+pixels we are sampling (including possibly the set of all pixels), then the
+comprehensive error function, for alignment reference image A, frame
+B, and transformation T, is:
+
+

+
+E(A, B, T) = (Sum [ p(i, j, A, B, T) ] / Sum [ p_max(i, j, A, B, T) ])(1/metric_exponent)
+

Monte Carlo Error

+
+
Use of Monte Carlo error can decrease the time required to align large images,
+since performing coordinate transformations and memory accesses at every pixel
+can be expensive.  Sections in this page describe the motivation for Monte
+Carlo alignment, the ratio calculations used, the sampling algorithm, cache
+behavior for the algorithm, randomization approaches, typical deviations from
+the specified ratios, special handling of level-of-detail, and practical
+observations regarding the use of Monte Carlo error.
+
+
Motivation

+
+
Performing large numbers of coordinate transformations and memory accesses in
+order to determine alignment error can be computationally expensive.  One
+approach to mitigating this expense is to use reduced level-of-detail.
+However, using reduced level-of-detail can also reduce alignment precision.  In
+particular, reducing the level of detail by a factor of two can make impossible
+the task of precisely aligning a horizontal line one pixel high.  However, if
+just a few pixels from the line are sampled at full detail, exact alignment is
+possible.
+
+
Ratio Calculations

+
+
In Monte Carlo alignment, a ratio 
+
+

+s = (expected # of pixel
+samples) / (# of total pixels in the accumulated image)
+

+
+is specified.  From this ratio, a new ratio 
+
+

+u = (expected # of unsampled pixels) / (expected # of sampled pixels)
+

+
+is calculated.  Pixels are sampled in such a manner that u is
+approximately satisified.  
+
+
At this stage, the region of overlap with the new frame is not considered.
+With a limited area of overlap, the number of actual samples contributing to
+the final error value will typically be reduced proportionally.  (Angelo Pesce
+has pointed out that better approaches may be possible, wherein explicit
+calculation of overlapping areas reduces the number of coordinate
+transformations performed.)
+
+
Sampling Algorithm

+
+
Pixels are considered in order of index, where the accumulated image pixel
+at position (i, j) is numbered with an index (i * width + j).
+In order of index, we skip and sample pixels in such a manner that the
+expected size of a run of consecutive skipped pixels preceding a sampled pixel
+is u.  We select the size of each run of consecutive skipped pixels as
+follows:
+
+
If 2 * u is an integer, then we draw uniformly from integer values in
+the interval [0,2u].  If it is not an integer, then we draw from integer values in
+the interval [0,2u + 1] in such a manner that integer values in
+[0,2u] are equally likely to be chosen.  
+
+
(Also, see the section below on interaction with level-of-detail.)
+
+
Cache behavior

+
+
Since indices are monotonically increasing in memory address, this approach
+to sampling may make effective use of memory cache where other approaches (e.g.
+repeated random draws from the entire index space) would not.  
+
+
Randomization

+
+
ALE versions 0.4.7 and earlier do not reseed the pseudorandom number generator,
+and so a new random subset is selected every time the error is evaluated.
+Hence, as more or fewer of the pixels critical to alignment are sampled, the
+reported alignment can worsen or improve even in the absence of any change in
+transformation.
+
+
With this approach, since many transformations are inspected during the
+alignment of any given frame, it is likely, especially with greater precision
+of alignment, that some measured differences between transformations are due to
+a difference in sample sets rather than a difference in alignment accuracy.
+
+
By reseeding the pseudorandom number generator, ALE versions 0.4.8 and later
+instead use a consistent set of pixels from the accumulated image when
+comparing two transformations.  Tests sampling 3% of pixels from a set of
+320x240 frames indicate that this approach improves alignment.
+
+
Sampling characteristics

+
+
For an image with 100,000 pixels and specified
+s in the interval [0.005,0.995], ALE's sampling method results in
+a ratio s within 0.000003 of the specified s.  This number 
+improves with image size.  (The results are outlined in a table.)  However, note that s only represents an expected
+value, and the actual number of sampled pixels may vary by more than the
+numbers given here.
+
+
Interaction with level-of-detail

+
+
When reduced level-of-detail is used, the number of reduced-detail pixels
+sampled is taken to be a percentage of the total number of pixels in the
+full-detail image, rather than as a percentage of the total number of pixels in
+the reduced-detail image.  (When this fraction of pixels in the full-detail
+image is more than the number of reduced-detail pixels available, all
+reduced-detail pixels are used.)  This may improve the likelihood of successful
+alignment, but may also add overhead to the alignment process.

Alignment

+
+
ALE aligns each supplemental frame, in sequence, with an alignment
+reference image constructed from previous frames.  This page outlines
+supported transformation classes, the algorithm used for alignment, and the
+properties of the alignment algorithm.  Following this is a discussion of
+practical use of alignment options, including alignment classes and alignment
+in the case of spatial extension.
+
+
Transformations

+
+
ALE offers the following classes of transformations: 

+
+
+
+
+
+
+
Translationsintroduced in version 0.0.0
Euclidean transformations (excluding reflections)introduced in version 0.1.0
Projective transformationsintroduced in version 0.2.0
Barrel distortion correctionintroduced in version 0.7.0

+
+
Algorithm

+
+
Alignment proceeds by a deterministic search, beginning with an initial
+transformation and modifying this transformation through a series of
+perturbations.
+
+
The initial transformation may be loaded from a file (when
+--trans-load is used) or selected by default, or may be the
+result of a global search (when --gs is used [0.7.1 only]).  The
+default initial transformation is either the transformation of the original
+frame (when the --identity option is specified) or the most
+recently aligned frame's final alignment (when the --follow option
+is specified).  When the initial transformation is loaded from a file, and if
+the --follow option is specified, any changes to the alignment of
+the previous frame are applied to the current frame at the outset.
+
+
Once the initial transformation is determined, an initial perturbation
+amount determines the step size by which each of the transformation parameters
+are changed.  In translational or Euclidean alignment, the perturbation amount
+is applied to translation -- in units of pixels on the two image axes -- and
+rotation -- in units of degrees about the image center.  An additional
+configurable upper bound, --rot-upper, constrains rotational
+perturbation separately, preventing, e.g., a 360 degree perturbation of
+rotation.  In the case of projective alignment, the perturbation amount is
+applied to the position of the corners of the projected quadrilateral in units
+of pixels, where the projection is from the boundary of the supplemental frame
+into the coordinate system of the alignment reference image.  In the case of barrel
+distortion correction, the perturbation amount is scaled by a multiplier
+(--bda-mult) before being applied to each barrel distortion
+coefficient (if any have been defined).  The rate of change of barrel distortion
+coefficients per frame can be limited with the option --bda-rate.
+
+
If possible, transformation parameters are changed to decrease the error between the supplemental frame and the alignment reference
+image.  The perturbation amount is halved whenever it is determined that no
+parameter change of the current perturbation size improves the alignment of the
+images.  A lower bound on the perturbation amount determines when the alignment
+is complete.
+
+
+
+
When multiple levels of detail are used, the error may be calculated on
+images with a reduced level of detail.  By default, this version of ALE uses a
+level of detail twice as fine as the perturbation amount for perturbation
+amounts larger than two, and full detail otherwise.  This behavior can be changed
+by adjusting the --lod-max option.

ALE Certainty

+
+
When used with a sequence of differently-exposed images, the certainty
+techniques implemented in ALE may produce output having higher fidelity overall
+than that of any single exposure.
+
+
Motivation

+
+
When multiple, differently-exposed images of the same scene are available,
+variations of intensity visible in one image might not be visible in another.
+In particular, if the difference between maximal light and dark values in the
+scene exceeds the range of the image capture apparatus, then no single exposure
+can faithfully record the scene.  Using multiple exposures allows discernment
+of at least as many details as any single exposure in the set can provide, and
+may allow discernment of more details, and better estimates of intensities.
+
+
Related Work

+
+
Steve Mann's original approach to certainty is described in his comparametric paper.  ALE extends
+his approach to Irani-Peleg rendering by defining certainty for (intensity,
+correction) pairs (in versions 0.7.x) and by basing certainty on estimated
+intensities (in version 0.8.0).
+
+
Two-sided Certainty

+
+
Two-sided certainty operator κ is used by ALE's incremental
+renderer, and applies a parameterized heuristic function:
+
+

+κd(i, j) = max(0.001, [1 - 4 * (0.5 - d(i, j))2]k)
+

+
+Where all operations are applied componentwise, and k is the certainty
+exponent parameter.
+
+
Symmetrically One-sided Certainty

+
+
Symmetrically one-sided certainty is used by ALE's Irani-Peleg renderer in
+versions 0.7.x, and is calculated using the direction of bias of a correction
+c(i, j) against a modeled pixel value m(i, j).  The following
+expression assumes the range of m to be [0, 1], and expresses
+condition using the C trinary if-else operator:
+
+

+Κ(c, m, i, j) = [c(i, j) * (m(i, j) - 0.5) > 0] ? 1 : κd(i, j)
+

+
+
Where all operations are applied componentwise, and κ is the
+operator for two-sided certainty.

+
+
Asymmetrically one-sided certainty

+
+Asymmetrically one-sided certainty applies the one-sided condition asymmetrically.
+
+

+Κ'(c, m, i, j) = [c(i, j) > 0 && (m(i, j) - 0.5) > 0] ? 1 : κd(i, j)
+

+
+
Estimate-based Certainty

+
+
Estimate-based certainty uses an estimate of intensity, rather than measured
+intensity, to determine certainty, and can be used in a one-sided or two-sided
+way.  ALE version 0.8.0 uses estimate-based asymmetrically one-sided certainty
+to weight Irani-Peleg correction values.

ALE Rendering Chains

+
+
In cases of spatially non-uniform resolution, rendering chains can maintain low
+aliasing in poorly-resolved regions while preserving detail in well-resolved
+regions.  Each chain is based on a sequence of rendering invariants, each
+allowing first, last, average, minimum, or maximum pixel values to be rendered.
+For a given invariant, exclusion regions are honored by default, but can
+optionally be ignored.  Finally, for a given invariant, resolution can be
+limited to the minimum of the input and output images, to prevent aliasing, or
+can use the full resolution of the output image, to prevent loss of fine
+details.

+
+

Chains

+
+
A chain c is based on a sequence of rendering invariants v1, v2, ..., vmax.  For each vx, define wx:
+
+

+wx(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = ∑n'∈0..n ∑(i', j')∈Dom[dn'] vx(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)
+

+
+
+If wt is the weight threshold (ALE option 'wt'), and there exists a smallest x such that:
+
+

+wx(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) ≥ wt
+

+
+Then c gives:
+
+

+c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = vx(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) / wx(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)
+

+
+Otherwise, c gives:
+
+

+c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = vmax(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) / wmax(n, i, j, E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)
+

+
+If both of the expressions above are undefined, then c gives:
+
+

+c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0
+

+
+
+
Invariants

+
+
There are five types of rendering invariants, all of which are parameterized
+with a scaled sampling filter with exclusion, denoted here by the symbol e.  In particular, an
+invariant can be of initial, final, maximal, minimal, or average type.  
+
+
Initial

+
+
If an invariant v is of initial type, then choose the smallest m such that
+the following expression is non-zero:
+
+

+∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)
+

+
+If such an m can be chosen, then, using the C trinary if-else operator to express condition:
+
+

+v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0
+

+
+Otherwise:
+
+
 v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0
+
 
+
+
Final

+
+
If an invariant v is of final type, then choose the largest m such that
+the following expression is non-zero:
+
+

+∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)
+

+
+If such an m can be chosen, then, using the C trinary if-else operator to express condition:
+
+

+v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0
+

+
+Otherwise:
+
+
 v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0
+
 
+
+
Minimal

+
+
If an invariant v is of minimal type, then choose m such that the following
+expression is defined and minimal:
+
+

+∑(i',j')∈Dom[dm] Em-1G-1dm(i',j') * e(m, i, j, i', j', Em, G, Pm, Bm, dm) / ∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)
+

+
+If such an m can be chosen, then, using the C trinary if-else operator to express condition:
+
+

+v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0
+

+
+Otherwise:
+
+

+v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0
+

+
+
Maximal

+
+
If an invariant v is of maximal type, then choose m such that the following
+expression is defined and maximal:
+
+

+∑(i',j')∈Dom[dm] Em-1G-1dm(i',j') * e(m, i, j, i', j', Em, G, Pm, Bm, dm) / ∑(i',j')∈Dom[dm] e(m, i, j, i', j', Em, G, Pm, Bm, dm)
+

+
+If such an m can be chosen, then, using the C trinary if-else operator to express condition:
+
+

+v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = (n' == m) ? e(m, i, j, i', j', Em, G, Pm, Bm, dm) : 0
+

+
+Otherwise:
+
+

+v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = 0
+

+
+
Average

+
+
If an invariant v is of average type, then:
+
+

+v(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn) = e(n', i, j, i', j', En', G, Pn', Bn', dn')
+

+
+
Scaled Sampling Filter with Exclusion (SSFE)

+
+
A scaled sampling filter with exclusion e is parameterized with a scaled sampling filter s, and
+can be of two types: it can either honor exclusion regions or not.  Define
+is_exclude(n', i, j) to be false if point (i, j) is not excluded
+for frame n', or if exclusion regions are not being honored.  Then,
+using the C trinary if-else operator to express condition:
+
+

+e(n', i, j, i', j', E, G, P, B, d) = is_exclude(n', i, j) ? 0 : s(i, j, i', j', P, B, κG-1E-1d)
+

+
+
Where κ is the operator for certainty.
+
+
Scaled Sampling Filter (SSF)

+
+
Define bayer(i, j) to be a function that returns an RGB value whose
+channels are either zero or one, depending on whether that color is sampled at
+(i, j).
+
+
A scaled sampling filter s is parameterized with a sampling filter
+f, and can be one of two types: fine or coarse.  If it is fine, then,
+using P and B as functions:
+
+

+s(i, j, i', j', P, B, k) = bayer(i', j') * k(i', j') * f(B(P(i', j')) - (i, j))
+

+
+
If SSF s is coarse, then color channels are handled separately,
+depending on their density relative to the output image, at point (i, j)
+in the output image.  In particular, bayer patterns can cause some colors to be
+more dense than others.  If the local density of channel h is lower in
+each dimension than the density of channel h in the output image, then:
+
+

+[s(i, j, i', j', P, B, k)]h = [bayer(i', j') * k(i', j') * f((i', j') - P-1(B-1(i, j)))]h
+

+
+
Otherwise, if channel h is locally less dense by a factor d in
+exactly one dimension of the input image, then set d_pair equal to
+(1, d) or (d, 1), according to the dimension, and:
+
+

+[s(i, j, i', j', P, B, k)]h = [bayer(i', j') * k(i', j') * f(d_pair * (B(P(i', j')) - (i, j)))]h
+

+
+
Otherwise, channel h is locally at least as dense in both dimensions of 
+the input image as it is dense in the output image.  In this case:
+
+

+[s(i, j, i', j', P, B, k)]h = [bayer(i', j') * k(i', j') * f(B(P(i', j')) - (i, j))]h
+

+
+
+

ALE Version 0.7.x/0.8.x Technical Description  

+
+
Purpose

+
+
This page discusses motivation, related work, models of program input,
+renderers, and the alignment algorithm, but does not cover the 3D scene
+reconstruction code in versions 0.7.2 and later.  Note also that some changes
+in 0.8.x might not yet be covered.  For information on ALE program operation and
+usage, see the User Manual for 0.7.x or 0.8.x.

+
+
Note: This document uses HTML 4 character entities.  Sigma is 'Σ'; summation is '∑'.

+
+
Motivation

+
+
Several factors in the imaging pipeline can affect output, sometimes
+degrading image quality, either individually or through combination.  Lens
+effects include barrel or pincushion distortion; the camera sensor and
+electronics can produce blurring, signal aliasing, noise, quantization, and
+non-linear effects; analog video signals can degrade in transmission; and
+various compression techniques and digital enhancements on- or off-camera can
+destroy image features.  In some cases, a better image can be produced through
+combining information contained in different images.

+
+
+
+
+
Imaging Pipeline

+
+
Related Work

+
+
Richard Hook and Andrew Fruchter's drizzling technique was designed
+to combine dithered undersampled images.  Previous versions of ALE supported this
+technique; the current version supports an approximation.
+
+
Steve Mann's work (e.g. here and here), on spatial extents,
+projective transformations, linear-colorspace image processing, and weighting
+by certainty functions, motivated ALE's adoption of these features.  A
+modified, "one-sided" approach to certainty is used by ALE's Irani-Peleg
+renderer, to better accommodate extremely bright features that exceed the range
+of all input images.  This approach is modified further in 0.8.0 to rely on
+estimated (instead of measured) intensities, which may allow further reduction
+of noise in some cases.
+
+
ALE incorporates an iterative solver based on Michal Irani and Shmuel
+Peleg's iterative
+deblurring and super-resolution technique.  It has been extended to handle
+convolutions occurring in tandem in different colorspaces, and has been
+modified for certainty weighting.
+
+
ALE's treatment of barrel distortion, using a polynomial in distance from
+the image center, is based on that of Helmut Dersch's Panorama Tools.  ALE's
+approach adjusts the linear (first-order) coefficient so that the corners of
+the transformed frame remain in place.

+
+
Program Inputs

+
+
Define an image to be a function mapping a subset of 2D Euclidean space to
+an RGB colorspace; define a discrete image to be an image defined only
+at coordinates having integral components; define a spatial discretization 
+to be an operator that restricts the domain of an image to a set of points
+having integral components, thus producing a discrete image; define a spatial
+extension to be an operator that extends the domain of a discrete image by 
+assigning the value of the nearest neighbor point.
+
+
Ignoring noise and color quantization, ALE assumes that each input frame
+dx is a discrete image that can be obtained by applying a
+sequence of operators, including transformations, exposure adjustment,
+convolutions, gamma correction, spatial discretization, and spatial extension,
+to some image d, as follows:
+
+

+dx = DNCGDLExBxPxd
+

+
+Where:
+
+
    
+
  • Px is a projective transformation
+
  • Bx is a barrel/pincushion distortion transformation
+
  • Ex is linear exposure adjustment
+
  • L is a convolution in linear colorspace
+
  • D is a spatial discretization
+
  • G is gamma correction
+
  • C is a spatial extension
+
  • N is a convolution in non-linear colorspace
+

+
+(When ALE aligns using Euclidean transformations, Px are
+assumed to be Euclidean.)
+
+
The presence of an extension operator between G and N is
+suspect, and is somewhat inelegant in the case of digitally processed data, but
+although such extension may require careful selection of N, it does not
+restrict the set of possible models.  It is only included because it creates a
+parallelism between N and L that makes implementation easier.
+In a more sophisticated implementation, it could be removed.

+
+
Incremental Rendering

+
+
If L and N are assumed to behave as identity operators, then each
+pixel in each input frame corresponds to a single point in d.  In this
+case, it may be possible to apply filtering operations to input frame pixels
+directly.  One caveat, however, is that different parts of the output may be
+sampled with unequal density in the input frame sequence; hence, a filtering
+approach that is uniform over all regions could cause significant aliasing or
+detail loss.  Instead, ALE uses a non-uniform approach.  If In(i,
+j) is an output pixel, at position (i, j), updated for input frames
+zero through n, then:
+
+

+In(i, j) = ∑n'∈0..n∑(i',j')∈Dom[dn'] En'-1G-1dn'(i',j') * c(n, n', i, j, i', j', E0, ..., En, G, P0, ..., Pn, B0, ..., Bn, d0, ..., dn)
+

+
+
Where c is a rendering chain.  Note that for most
+types of rendering chains, the above expression can be simplified considerably.
+
+
Irani-Peleg Rendering

+
+ALE's Irani-Peleg renderer iteratively updates the final output of incremental
+rendering, with update operator U:
+
+

+J0 = Ifinal
+

+J1 = UJ0
+

+.
+

+.
+

+.
+

+Jk = UJk-1
+

+
+Where U is the Irani-Peleg update rule.
+
+
Spatial Extension and Space Complexity

+
+
By default, the output image is of fixed size, limited to the extents of
+d0, the first image in the input sequence; the 'extend' option
+specifies that output should accommodate all regions of all input images.
+
+
When rendering an output image of fixed size, image storage space in memory
+for all non-median rendering types is O(1) in the number of input frames
+and O(n) in the number of pixels per input frame, since at most one
+input image is loaded into memory at any time.  For median-value rendering,
+storage is O(n) in the number of input frames.  When using projectively-aligned
+input images, however, renderings that accommodate all regions of all input
+images can generate arbitrarily large output for a bounded input size, and can
+use an arbitrarily large amount of memory.
+

3D Scene Reconstruction

+
+
The scene reconstruction code is still very experimental and is not
+currently covered by this document.  For more information, see the user manual
+and source code.

ALE Irani-Peleg Update Rule

+
+The Irani-Peleg update operator U is used iteratively to update the
+final output of incremental rendering:
+
+

+J0 = Ifinal
+

+J1 = UJ0
+

+J2 = UJ1
+

+.
+

+.
+

+.
+

+Jk = UJk-1
+

+
+
Modeling of the imaging process

+
+
Given transformations Px and Bx, linear
+exposure adjustment Ex, linear and non-linear convolutions
+L and N, discretization operator D, and extension operator
+C, the imaging process can be modeled, starting with s, a
+discrete approximation of the scene, as:
+
+

+dx = DNCGDLExBxPxCs
+

+
+
Note the extension operator to the left of s, which was not present
+in the similar equation appearing on the main page.  Since we are using only a
+discrete approximation of the scene, it must first be made continuous, in order
+to fit within the framework developed on the main page.  As noted before, the
+second extension operator, between G and N, is included for
+convenience of implementation, and does not restrict the generality of the model.
+
+
Pixel-to-pixel weighting

+
+
Since pixel values in DLExBxPxCs are
+linear in pixel values of Cs, and hence linear in pixel values of
+s, and since, similarly, pixel values of dx are linear
+in pixel values of GDLExBxPxCs, we can
+define arrays of values a and b such that:
+
+

+DLExBxPxCs(i, j) = ∑(i', j') ax,i,j,i',j' * s(i', j')
+


+dx(i, j) = ∑(i', j') bx,i,j,i',j' * GDLExBxPxCs(i', j')
+

+
+Hence, using G as a gamma correction function:
+
+

+dx(i, j) = ∑(i', j') bx,i,j,i',j' * G(∑(i'', j'') ax,i',j',i'',j'' * s(i'', j''))
+

+
+Note that, since G is non-linear, the inner sum cannot be moved outside of the enclosing parentheses.
+
+
Error calculation

+
+
Given the model described above, we now have two ways to calculate a pixel value dx(i, j): directly, from the input frame, or indirectly, from the scene approximation s.  Hence, we can calculate an error between the two methods:
+
+

+ex(i, j) = dx(i, j) - ∑(i', j') bx,i,j,i',j' * G(∑(i'', j'') ax,i',j',i'',j'' * s(i'', j''))
+

+
+
Backprojection (single stage)

+
+Assume for the moment that our model of dx were restricted in the following way, using a scene approximation s':
+
+

+dx(i, j) = ∑(i', j') bx,i,j,i',j' * s'(i', j')
+

+
+
This includes, as a special case, the scenario originally outlined by Irani and
+Peleg, which considered a single convolution step.  In this case, we can use a
+backprojection array c to produce an updated image Us':
+
+

+Us'(i, j) = s'(i, j) + (1 / xmax) * ∑x ∑(i', j') cx,i,j,i',j' * ex(i', j')
+

+
+
For certain limited cases, Irani and Peleg have proved this update rule to
+converge exponentially to the original scene.  However, since the model used by
+ALE includes two convolution steps that cannot, in general, be combined, ALE
+uses a different update rule.
+
+
Backprojection (two-stage)

+
+
The two-stage backprojection rule below could easily be extended to any
+arbitrary number of stages, but ALE currently supports only two stages, in
+accordance with the two-colorspace imaging model outlined above.  The rule,
+using G-1 as an inverse gamma correction function, is:

+
+

+Us(i, j) = s(i, j) + (1 / xmax) ∑x ∑(i', j') cx,i,j,i',j' * (G-1(GDLExBxPxCs(i', j') + ∑(i'', j'') fx,i',j',i'',j'' * ex(i'',j'')) - DLExBxPxCs(i', j'))
+

+
+
Where f is a second backprojection array.  Schematically, the update
+process looks something like the diagram below, based on an excerpt from the
+ALE source code.  The exposure re-estimation step shown in the diagram has not
+been described here, but is available for inspection in the source.  Also,
+since ALE stores images internally using a linear representation, they must
+first be converted back to a non-linear representation, as shown at the very
+bottom of the diagram.

+
+

+
+ * The algorithm in the paper by Irani and Peleg looks something like this
+ * (PSF' is the backprojection kernel, and corresponds to what the authors of
+ * the paper call AUX):
+ *
+ * ===============================================================
+ *    Forward         Backward           Binary Operators
+ * ---------------------------------------------------------------

+ *
+ * ===============================================================
+ *
+ * The above approach assumes a single colorspace representation.  However,
+ * consumer cameras sometimes perform sharpening in non-linear colorspace,
+ * whereas lens and sensor blurring occurs in linear colorspace.  Hence, there
+ * can be two colorspaces involved; ALE accounts for this with linear and
+ * non-linear colorspace PSFs.  Hence, the algorithm we use looks something

+
Backprojection Arrays

+
+
The rules used for calculating backprojection arrays c and f are as follows:

+
+

+cx,i,j,i',j' = Y * bx,i,j,i',j'
+


+fx,i,j,i',j' = Z * ax,i,j,i',j'
+

+
+
Such that:
+
+
+
+

+Y = - 0.9 / (maxω |FKb(ω)|)
+


+Z = - 0.9 / (maxω |FKa(ω)|)
+

+
+
where F is the fourier transform, Ka is the convolution kernel for a
+in its native coordinate system, and Kb is the convolution kernel for b in its native coordinate
+system.
+
+
Convergence for special cases

+
+
In cases where at least one of L, N, or G is the
+identity operator, or if G is linear, the technique outlined above can
+be expressed in terms of the original method by Irani and Peleg, and will
+converge exponentially if it meets the convergence criteria outlined in their
+paper.  Note that ALE makes certain approximations to obtain projection and
+backprojection arrays that may hinder convergence in some cases.  In particular,
+the calculation of overlap areas involving non-identity transformations is not
+exact.

+
+
Certainty

+
+
ALE's implementation of certainty for Irani-Peleg rendering modifies the rule
+described above.  Write the original rule as:

+
+

+Us(i, j) = s(i, j) + (1 / xmax) ∑x correctionx(i, j)
+

+
+
where correctionx represents the back-projected correction
+for frame x.  Let the re-estimated linear value comp_real,
+lreal(n) in the diagram above, be defined as:
+
+

+comp_realx(i, j) = G-1(GDLExBxPxCs(i, j) + ∑(i'', j'') fx,i,j,i'',j'' * ex(i'',j''))
+

+
+Then the certainty-based rule for versions 0.7.x is:
+
+

+Us(i, j) = s(i, j) + ∑x Κ(correctionx, Excomp_realx, i, j) * correctionx(i, j) / ∑x K(correctionx, Excomp_realx, i, j)
+

+
+
Where Κ is the symmetrically one-sided certainty function.  
+
+
For version 0.8.0, the rule is:

+
+

+Us(i, j) = s(i, j) + ∑x Κ'(correctionx, s, i, j) * correctionx(i, j) / ∑x Κ'(correctionx, s, i, j)
+

+
+
Where Κ' is the asymmetrically one-sided certainty function.  Note that this expression substitutes s for Excomp_realx, resulting in estimate-based certainty.

ALE 3D Modeling [Very Experimental]

+
+
When considering images captured by a camera, the projective class of 2D
+transformations can compensate for arbitrary changes in position and
+orientation when the scene consists of a diffuse flat surface, and arbitrary
+changes in orientation (but not position) otherwise.  In order to support
+changes of position and orientation in the general case, it is necessary to
+construct a 3D model of the scene.  ALE currently has no reliable method for
+doing this, but the scene reconstruction code included in versions 0.7.2 and
+later may be a useful starting point for developing such a method.
+
+
View Angle

+
+
In versions 0.7.3 and above, the diagonal view angle of the camera can be
+specified on the command line.  If no value is specified, the default value is
+either device specific (if a device with a known view angle is specified), 43.7
+degrees [ALE 0.7.3 and above], or 90 degrees [ALE 0.7.2].
+
+
+--view-angle <x>  Set the diagonal view angle to <x> degrees.  [ALE 0.7.3 and above]
+

+
+
View Output [Very Experimental]

+
+The view output option provides a reconstruction of the scene as viewed from a
+particular frame's vantage point.
+
+
+--3dv <n> <o>     Render file <o> from a 3D model using the <n>th frame view.  [Very Experimental]

ALE Transformation Data Files

+
+Transformation data files are useful when performing alignment in several
+passes or refining rendering options, and are necessary for specifying
+barrel/pincushion distortion parameters.  They also offer a way to manually
+specify alignment when ALE cannot automatically align images.  
+
+
Multiple-pass alignment

+
+To align images in multiple passes, load the saved results of each previous
+pass, as follows:
+
+
+$ ale --trans-save=a.t <first pass arguments>
+$ ale --trans-load=a.t --trans-save=b.t <second pass arguments>
+$ ale --trans-load=b.t --trans-save=c.t <third pass arguments>
+.
+.
+.
+

+
+
Rendering option refinement

+
+To refine rendering options using the same alignment, first save the alignment
+for the first option set, and then load the saved alignment information with
+each subsequent option set, setting the perturbation upper bound to zero to
+prevent a new alignment pass from occurring:
+
+
+$ ale --trans-save=a.t <first option set>
+$ ale --trans-load=a.t --perturb-upper=0 <second option set>
+$ ale --trans-load=a.t --perturb-upper=0 <third option set>
+.
+.
+.
+

+
+
Alignment file syntax (version 2)

+
+There are two varieties of alignment file syntax that are both read and written
+by ALE 0.7.0.  The most basic of these is version 2.  Version 3 is slightly
+more complex, and is covered in the next section.
+
+At the highest level, version 2 transformation data files contain the following
+components: (a) a version command, and (b) a sequence of transformation
+commands, one for each supplemental frame.  Each line of text should contain at
+most one command, between which optional comments may be interspersed.  A
+transformation command can be Euclidean, projective, or default.  Euclidean and
+projective commands take several arguments, including the width and height of
+the supplemental frame.  Default commands take no arguments.  Commands are
+outlined in more detail below.
+
+
Version command

+
+
The version 2 version command is as follows:

+
+
+V 2
+

+
+
Euclidean commands

+
+
The structure of a Euclidean command is as follows:

+
+
+E <image width> <image height> <x-offset> <y-offset> <rotation-angle>
+

+
+
Projective commands

+
+
Projective commands map the four corners of the supplemental frame to four
+points in the rendering coordinate system:

+
+
+P <image width> <image height> <top-left-x> <top-left-y> <blx> <bly> <brx> <bry> <trx> <try>
+

+
+
Default commands

+
+Default commands can be explicitly written as follows:
+
+
+D
+

+
+Alternatively, if there are more frames than alignment commands (euclidean,
+projective, or default), then the last supplemental frames in the frame
+sequence will be assigned the default command.
+
+
Comments

+
+Comments can be inserted with the following syntax:
+
+
+# This comment extends to the end of this line.  I can write anything I want here.
+

+
+
Alignment file syntax (version 3)

+
+Version 3 syntax is required for specifying transformations for the original
+frame, and for specifying barrel/pincushion distortion parameters.  
+
+
In version 3, the first transformation command is associated with the
+original frame, instead of being associated with the first supplemental frame.
+Also, barrel/pincushion distortion commands can precede each projective,
+Euclidean, or default command.
+
+
Version command

+
+
The version 3 version command is as follows:

+
+
+V 3
+

+
+
Barrel/pincushion distortion command

+
+In version 3, barrel/pincushion distortion commands are supported.  Distortion
+is modeled as a transformation affecting the distance of image features from the
+image center.  The distorted distance is expressed as a polynomial function of
+the undistorted distance.  Zeroth and first order coefficients are fixed or
+automatically determined; additional coefficients can be specified explicitly,
+using the following syntax:
+
+
+B <n> <coefficient 2> <coefficient 3> ... <coefficient n+1>
+

+
+
Barrel/pincushion distortion commands should precede the projective, Euclidean,
+or default transformation command for the corresponding frame.

Alignment

+
+
Alignment compares each supplemental frame in the sequence with an intermediate
+incremental rendering known as the alignment reference image.  Based on this
+comparison, a transformation is assigned to the supplemental frame.  Many
+different transformations can be assigned before alignment of the frame is
+complete.
+
+
This manual page offers an overview of alignment options; linked from this
+page is a sub-page offering more detail on transformation
+data files.
+
+
Transformations

+
+
The variables used to adjust alignment are called transformations; they map
+points from the source image coordinate system to a target coordinate system
+(the rendering coordinate system).
+
+
ALE supports three transformation classes -- translational, euclidean, and
+projective -- as well as barrel/pincushion distortion correction.  The
+translational class applies only translations to the inputs, changing only the
+positions of images; the Euclidean class applies translations and rotations;
+and the projective class applies general projective transformations.
+Additionally, barrel/pincushion distortion correction can be applied to each
+frame.  The Euclidean class is most appropriate for use with scanners, or as a
+first pass for projective transformations.  The projective class and
+barrel/pincushion distortion correction are most appropriate for use with
+cameras.  Except when capturing flat scenes, ALE does not correct perspective
+changes, so movement of cameras should ideally be constrained so that no large
+translations occur.
+
+
Transformation Class Options

+
+
+--translation     Only adjust the position of images
+--euclidean       Adjust the position and orientation of images [default]
+--projective      Use projective transformations.  Best quality, but slow.
+

+
+For more information on barrel distortion correction, see the sub-page on 
+transformation data files.
+
+
Transformation data file options

+
+
Transformations used in alignment can be loaded from, or saved to, a transformation data file.  This can be useful when performing
+alignment in several passes, or when refining rendering options.  A
+transformation data file is required for barrel/pincushion distortion
+correction.
+
+
+--trans-load=x    Load initial transformation settings from file x
+--trans-save=x    Save final transformation data in file x
+

+
+
Alignment following

+
+
The --follow option hints that frames tend to be more closely aligned with
+adjacent frames in the sequence than with the original frame.  This hint can be
+useful even when initial alignment information is loaded from a file.
+
+
+--identity        Frames align closely with the original frame.  [default]
+--follow          Frames align closely with their immediate predecessor.
+

+
+
Match statistics

+
+
The match statistic indicates how well a transformed frame aligns with the
+alignment reference image; it is used to select or reject transformations
+during alignment.  After alignment of a particular frame is complete, ALE
+displays the corresponding final match statistic.  If the value is close to
+100%, then the frames are well aligned; very low values can indicate
+misalignment; but even frames that are very well aligned typically do not
+achieve 100% alignment.  For improving image quality, ALE works most
+effectively when match values are lower than 100%.
+
+
Match threshold

+
+
A match threshold can be specified; no images with final match statistics
+falling below this threshold will contribute to the final output.
+
+
+--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)
+

+
+
Alignment failure

+
+
When an image fails to meet the match threshold, a transformation is still
+assigned to the frame (e.g., for writing to a transformation
+data file).  The assigned transformation can be either the optimal
+alignment found (this is default) or the default transformation.
+
+
+--fail-optimal    Frames beneath threshold are aligned optimally.  [default]
+--fail-default    Frames beneath threshold keep their default alignment.
+

+
+
Alignment error metric exponent

+
+
The function calculated at each pixel to determine the match statistic is called
+the alignment error metric, and is of the form (a-b)x.
+The value x is called the error metric exponent, and is 2 by default.
+Larger numbers indicate that alignment will be more influenced by smaller
+image features.
+
+
+--metric=x        Set the alignment error metric exponent.       (2 is default)
+

+
+
Alignment Channel Options

+
+
In calculating the per-pixel error metric, there are three ways in which ALE
+can handle color channels.  By default, ALE adds the channels before
+calculating the match, but it can also be configured to rely solely on the
+green color channel, or to use all three channels separately.
+
+
+--align-all       Align images using all color channels
+--align-green     Align images using the green channel
+--align-sum       Align images using a sum of channels [default]
+

+
+
Monte Carlo Alignment

+
+
Aligning large images can take a very long time if all pixels are examined in
+determining the match statistic, so it is often desirable to examine a smaller
+subset of pixels.  The Monte Carlo alignment option allows this.  The number of
+pixels used is specified as a percentage, and smaller numbers usually mean
+faster, but less precise, alignment.  For defaults, see the 
+default settings page.
+
+
+--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
+--no-mc           Align using all pixels.
+

+
+
Alignment weight map

+
+
Typically, measured differences at each pixel in the alignment reference
+image contribute equally to the match statistic.  To weight pixels differently,
+a weight map can be used.  The scale of the map should correspond with that of
+the alignment reference image, and if the upper-left corner of the map does not
+coincide with the upper-left corner of the first frame in the sequence, then a
+non-zero offset should be specified to indicate the difference.  See also exclusion regions.
+
+
+--wm <f> <x> <y>  Use weight map image <f> at offset (<x>, <y>)
+

+
+
Frequency weighting

+
+
If ALE is compiled with FFTW support, then a high-pass-filtered version of
+the alignment reference image can be used to weight reference image pixels'
+contributions to the match statistic.  Frequency limiting can occur as a
+fraction of the highest horizontal frequency, the highest vertical frequency,
+or the highest average frequency.  Limit values should range between 0 (pass
+all) and 1 (pass none).  If any limit is assigned a value of 1, no alignment
+will occur, since all frequencies will have been excluded.  An output file can
+optionally be specified for high-pass filtered data.

+
+
+--fl <h> <v> <a>  High-pass filters: horizontal <h>, vertical <v>, average <a>.
+--flshow <o>      Write high-pass filtered data to file <o>.
+

+
+
Algorithmic weighting

+
+
This option writes the current alignment reference image and definition map
+to specified files, executes a specified program with these arguments, and then
+reads back alignment weights.  This option requires POSIX libraries, and
+requires that ALE have been built with POSIX support enabled.

+
+
+--wmx <e> <r> <d> Write reference <r>, definition <d>, execute `<e> <f> <d>`,
+                  read weights <r> back.
+

+
+
Perturbation

+
+
The perturbation size determines the magnitude by which alignment parameters
+are changed.  The size is initially set to be large, allowing large changes in
+alignment to be evaluated, and is reduced as the locally optimal alignment is
+found for each size.  When this size drops below a specified lower bound, the
+frame is considered to be aligned.
+
+
Perturbation bounds

+
+
These options determine the upper and lower bounds for perturbation size.  The
+perturb-upper and perturb-lower bounds apply to rotation (in degrees),
+translation (in pixels), and the movement of the boundaries of a projected
+frame (in pixels).  By appending the '%' character, values may optionally be
+specified as a percentage of the number of pixels in the smallest image
+dimension (0.7.1-patch1 and later).  The rot-upper bound disables rotational
+perturbation above a certain perturbation size (in degrees).  To disable
+alignment, set perturb-upper to zero.
+
+
+--perturb-upper=x Perturbation upper bound in pixels/degrees   (14% is default)   [0.7.1, and earlier, default to 32.0]
+                     ('x%' uses a fraction of the smallest image dimension.)      [0.7.1-patch1 and later]
+--perturb-lower=x Perturbation lower bound in pixels/degrees  (.125 is default)
+                     ('x%' uses a fraction of the smallest image dimension.)      [0.7.1-patch1 and later]
+--rot-upper=x     Rotation-specific perturbation upper bound  (32.0 is default)
+

+
+
Barrel/pincushion distortion adjustment multiplier and rate

+
+
When using barrel/pincushion distortion parameters, any frame-to-frame
+adjustments to these parameters are made in a manner dependent on the
+perturbation size.  A multiplier, the barrel distortion adjustment multiplier,
+is used to determine the perturbation of these parameters, based on the generic
+perturbation size.  Additionally, the frame-to-frame rate of change of each
+barrel distortion parameter can be limited to a specified maximum.  To disable
+frame-to-frame adjustment of barrel/pincushion distortion parameters, set
+bda-mult to zero.  Setting bda-rate to zero disables rate limitation.
+
+
+--bda-mult=x      Barrel distortion adjustment multiplier   (0.0001 is default)
+--bda-rate=x      Barrel distortion rate of change maximum  (0.0004 is default)
+

+
+
Level of detail

+
+
Alignment at large perturbation sizes is usually carried out on
+reduced-detail images.  To disable this, set lod-max to
+log2(perturb-upper).
+
+
+--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)
+

+
+
Perturbation Types (experimental; 0.7.1-patch1 and later)

+
+
Perturbations are normally performed in output image coordinates.  To perform
+perturbations in source image coordinates, specify --perturb-source.
+
+
+--perturb-output  Apply perturbations in output image coordinates. [default]  [0.7.1-patch1 and later]
+--perturb-source  Apply perturbations in source image coordinates.            [0.7.1-patch1 and later]
+

+
+
Global Searching (experimental; 0.7.0-patch1 and later)

+
+
In cases where important image features do not have sufficient overlap using
+default alignment parameters (determined by --identity and
+--follow), a number of translations can be applied to the default
+parameters in order to find a new alignment starting point.  Since this process
+searches the entire region of the alignment reference image, it is called a
+global (as opposed to local) search.  To avoid misalignment, a minimum overlap
+area can be specified [0.7.1-patch2 and later].
+
+
+--gs <type>       Set global search to <type>, one of:                             [0.7.0-patch1 and later]
+                     local     Local alignment only [default]
+                     inner     Alignment reference image inner region
+                     outer     Alignment reference image outer region
+                     all       Union of inner and outer
+                     central   inner if below threshold or better; else, outer.
+
+--gs-mo <x>       Set <x> pixel min. overlap for global search. (16 is default)    [0.7.1-patch2 and later]
+

ALE Default Settings

+
+
ALE offers five different default settings, each of which emphasizes
+image quality, speed, or some other rendering characteristic, as follows:

+
+
+--q0              Low quality, high speed. [default]
+--qn              Low noise, moderate speed.
+--q1              Moderate quality and speed.
+--q2              High quality, low speed.
+--qr              Range-extended high quality.
+

+
+
These settings specify defaults for other options: --dchain, --achain,
+--mc, --ips, --exp-extend, and --cx.  For
+more information about these options, see the alignment and rendering
+manual pages.  Details regarding these defaults are provided in the following sections.
+
+
High speed (--q0)

+
+--q0 emphasizes speed over image quality.  This option is default, and
+sets other options' defaults as follows:
+
+
+   --dchain fine:box:1,triangle:2
+   --achain triangle:2
+   --mc 30
+   --ips 0
+   --exp-noextend
+   --no-cx
+

+
+
Low noise (--qn)

+
+--qn emphasizes low noise over resolution and rendering speed, and
+sets the following defaults:
+
+
+   --dchain sinc*lanc:6
+   --achain sinc*lanc:6
+   --mc 50
+   --ips 0
+   --exp-noextend
+   --no-cx
+

+
+
Balanced quality and speed (--q1)

+
+--q1 balances image quality and rendering speed, offering higher
+resolution than --qn.  It sets the following defaults:
+
+
+   --dchain fine:sinc*lanc:6,sinc*lanc:6
+   --achain sinc*lanc:6
+   --mc 50
+   --ips 0
+   --exp-noextend
+   --no-cx
+

+
+
High quality (--q2)

+
+
--q2 favors image quality over rendering speed, offering greater
+emphasis for high-frequency details than --q0, --qn,
+or --q1.  It depends on the --lpsf and
+--nlpsf options, which can be set indirectly via the
+--device option.  (More information about these options can be
+found on the PSF and device pages.)  --q2
+sets the following defaults:
+
+
+   --dchain sinc*lanc:8
+   --achain sinc*lanc:8
+   --no-mc
+   --ips 4
+   --exp-noextend
+   --no-cx
+

+
+
Range extension (--qr)

+
+
--qr is similar to --q2, but offers improved
+rendering when input images have been taken with unequal exposures.  In other
+cases, it might exacerbate noise in light and dark regions, and so should not
+be used.  This option sets the following defaults:
+
+
+   --dchain sinc*lanc:8
+   --achain sinc*lanc:8
+   --no-mc
+   --ips 6
+   --exp-extend
+   --cx 0.7

ALE Devices

+
+
Device specification is optional.  Specifying a device allows automatic
+determination of point-spread functions,
+refinement of the correspondence between incident light and pixel values (e.g.
+power law), and refinement of certainty calculation.  
+
+
+--device <d>      Set the capture device to <d>.
+

+
+
Available devices are as follows:

+
+
+
canon_300d_raw_linearCanon 300D (Digital Rebel) raw, linear data.  [0.7.2 and later]
+
canon_300d_raw_linear+50mm_1.4Canon 300D with EF 50mm f/1.4 lens, unspecified aperture.
+

+
xvp610_320x240IBM PC Camera Pro (XVP610) in 320x240 mode.
+

+
+
These device options are described in more detail below.
+
+
Canon 300D (Digital Rebel) [0.7.2 and later]

+
+
Direct support for CRW files depends on the ImageMagick configuration, and
+may not be available on all platforms.  Dave Coffin's dcraw program, invoked with
+arguments -d -4, will produce a raw, linear PPM file suitable for use with this
+device configuration.  JPEG files produced by the 300D cannot be directly used
+as inputs for this configuration, since they are gamma-corrected rather than
+linear.

+
+
OV7620 [0.7.0-patch1 and later]

+
+
Standard OV7620 drivers may not include options for setting raw RGB or linear
+modes.  Linux users may apply a driver patch to access
+these modes.  Setting the module option rgb_raw=2 places the camera
+into the desired mode.

+
+
XVP610

+
+
Users of XVP610 cameras and Linux may wish to apply a driver patch.  This version of ALE expects that this patch has been applied.

ALE Exclusion Regions

+
+
ALE offers exclusion regions as a way to disallow certain areas from being
+used in alignment and (optionally) rendering.  Spatial coordinates are
+expressed in the rendering coordinate system (prior to scaling).  In cases
+where the default transformation is used with the original frame, this is
+identical to the unscaled original frame coordinate system, taking the
+upper-left corner to be (0, 0).  Frame numbering begins with 0, which represents
+the original frame.
+
+
All specified volumes are excluded from alignment (except where they affect
+the alignment reference image), and are excluded from rendering by default.
+(See the rendering chains page for
+information on how to ignore exclusion regions.)  Exclusion region syntax is
+as follows:
+
+
+--ex <args>       Exclude a specified volume.
+                     <args> are space-delimited horizontal,
+                     vertical, and frame limits:
+                         <xmin> <xmax> <ymin> <ymax> <fmin> <fmax>

ALE File Output

+
+
File output options determine the format in which rendered images are written,
+and how frequently they are written.  Depending on the compilation options used,
+available file output options vary.
+
+
Output Color Depth

+
+
Output color depth of 8 or 16 bits of precision per color channel can be specified,
+for 24-bit or 48-bit color, respectively.  
+
+
+--8bpc            Write 8 bit per channel output [default]
+--16bpc           Write 16 bit per channel output
+

+
+
Extension-based file type determination

+
+
If ALE has been built with ImageMagick support, then the output file type can
+be determined automatically by file extension.  This is the default behavior
+for ImageMagick builds.  The --auto flag explicitly specifies that
+the default behavior should be used; it generates an error on builds compiled
+without ImageMagick support.  
+
+
+--auto            Determine file type automatically
+

+
+
PPM Output

+
+
All builds of ALE support PPM output.  PPM can be written in plain (ASCII) or
+raw (binary) format.  If ALE has been built without ImageMagick support, or if
+the file type cannot be automatically determined by file extension, then raw
+PPM output is used by default.
+
+
+--raw             Write raw PPM output
+--plain           Write plain PPM output
+

+
+
Incremental Output

+
+
By default, ALE writes intermediate results periodically throughout the rendering
+process.  This behavior can be disabled, however, so that output is written only
+after rendering is complete.
+
+
+--inc             Produce incremental output.  [default]
+--no-inc          Don't produce incremental output.

ALE 0.7.x User Manual

+
+
Purpose

+
+
This page summarizes program operation and command-line usage for ALE
+versions 0.7.0, 0.7.0-patch1, 0.7.1, 0.7.1-patch1, 0.7.1-patch2, and 0.7.2.
+Features specific to a particular version are annotated (e.g. [ALE 0.7.1
+only]).
+
+
Manual pages linked from this section describe default
+settings, file output, alignment, rendering, exclusion regions, devices, and
+3D scene reconstruction (Very experimental; ALE 0.7.2 and
+later).
+
+
For more information on ALE, see the ALE Home Page.
+
+
Parameter Meta-syntax

+
+
+
+
+
+
+
+
+
+
+
+
+
 <foo>A required parameter called foo.
[<foo>]An optional parameter called foo.
+
[<foo>]*Zero or more parameters foo.
+

+
+
Command-line syntax for Image Processing

+
+
The following command-line invocation can be used to process a series of
+frames into an output file:
+
+
ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>

+
+
Option Arguments

+
+
Certain basic modes of operation, emphasizing image quality, speed, or other
+rendering characteristics, are now established in the form of default settings.
+
+
Other options are outlined in the manual pages describing file output, rendering, alignment, exclusion
+regions, devices, and 3D scene
+reconstruction (Very experimental; ALE 0.7.2 and later).
+
+
Image Files

+
+
ALE can be configured at compile time to use one of two different file
+handlers.  Execute 'ale --version' to determine which file handler is being
+used.  The table below outlines the supported formats for each file handler.

+
+
+

+
+
+
+
+
+
+
+
Version MessageFile Types Supported

+
File handler:     ImageMagick

+		
+Input and output files can be any of the formats supported by
+ImageMagick.
+

+
File handler:     PPM

+		
+Input files must be PPM, and output files are written as PPM.
+

+

+
+
Note that many external programs, including ImageMagick's command line utilities, can be used to
+convert between PPM and other formats.

+
+
See the README included in the source distribution of ALE for more information about
+compile-time configuration of file handlers.

+
+
Command-line syntax for Version Information

+
+
The following command-line invocation can be used to print version
+information and build options:
+
+
ale --version

+
+The following is sample output from this invocation:
+
+
+ALE Version:      0.7.2
+File handler:     ImageMagick
+Color data:       SINGLE
+Coordinate data:  SINGLE
+DFT:              Built-in
+Assertions:       Disabled
+

+
+
The first line of output indicates the version of ALE source code being
+used; the remaining lines reflect the build options selected at compile
+time.
+
+
For more information about build options, see the README file included in
+the ALE source distribution.
+
+
Command-line syntax for Help Output

+
+
When invoked with no arguments, or an insufficient number of file arguments,
+ALE outputs a help message specifying command-line usage and available help
+topics.  The following is a sample invocation:
+
+
ale

+
+
Help Topics

+
+More information about specific help topics can be obtained with an invocation
+of the following form:
+
+
ale <help option>

+
+Available help options, and their corresponding help topics, are outlined

ALE Rendering Chains

+
+
The ALE incremental renderer is configured using rendering chains.  Rendering chains are
+constructed hierarchically from: invariants, SSFEs (scaled sampling filters
+with exclusion), SSFs (scaled sampling filters), and sampling filters.  Each of
+these components is described in a section below.  Defaults are outlined in the
+final section.
+
+
Chains

+
+
The chain is the top level of the rendering chain hierarchy, and is composed of a
+sequence of invariants.  Syntactically, a chain is specified as a number of
+invariants separated by commas:
+
+

+invariant1,invariant2,invariant3,...,invariantn
+

+
+
Each rendered pixel is assigned a value at the first invariant whose weight
+exceeds the weight threshold, or otherwise at the last invariant in the sequence.
+
+
Chain Options

+
+
+--wt <w>          Set weight threshold for defined pixels    (default is 0.8).
+--dchain <g>      Use chain <g> to render the default output.
+--ochain <g> <o>  Use chain <g> to render output file <o>.
+--achain <g>      Use chain <g> to render the alignment reference image.
+

+
+

+             fine:sinc*lanc:8,sinc*lanc:8         Multi-resolution rendering
+

+
+
Invariants

+
+
Invariants determine whether the rendered pixel value should be taken from a
+single frame, or from an average of all frames.  If from a single frame, it can
+be the first, last, minimal, or maximal pixel value.  By default, the average
+is used.  The syntax is as follows:
+
+

+
+
+
Syntax
   
Description
avg:<SSFE>Average value
+
max:<SSFE>Maximum value
+
min:<SSFE>Minimum value
+
first:<SSFE>First value
+
last:<SSFE>Last value
+
<SSFE>Same as avg:<SSFE>
+

+

+
+
Scaled Sampling Filter with Exclusion (SSFE)

+
+
SSFEs qualify SSFs, indicating whether exclusion regions should be honored.
+
+

+
+
+
Syntax
   
Description
ex:<SSF>Honor exclusion regions
+
nex:<SSF>Don't honor exclusion regions
+
<SSF>Same as ex:<SSF>
+

+

+
+
Scaled Sampling Filter (SSF)

+
+
SSFs indicate whether filtering should occur at the resolution of the output
+image, or at the minimum of input and output image resolutions.  The former prevents loss
+of details; the latter prevents aliasing.
+
+

+
+
+
Syntax
   
Description
fine:<SF>Filter at full output image resolution
+
coarse:<SF>Filter at minimum resolution
+
<SF>Same as coarse:<SF>
+

+

+
+
SSF Options

+
+--afilter <s>     Use SSF <s> to interpolate points in alignment.
+

+
+
Sampling Filter (SF)

+
+
SFs are used to limit bandwidth.  Primitive functions and pointwise multiplication of these
+functions (windowing) are available.
+
+

+
+
+
+
Syntax
   
Description
sincSinc filter: (sin πx) / (πx)
lanc:<x>Lanczos, diameter x.
+
triangle:<x>Triangle, diameter x.
+
box:<x>Box, diameter x.
+
zeroZero function
+
<f>*<f>Pointwise multiplication (windowing)
+

+

+
+
Defaults

+
+
ALE defaults are as follows:

+
+
+                     dchain         Varies by default setting
+                     achain         Varies by default setting
+                     afilter        internal (approximates triangle:2)

+
ALE Rendering

+
+
Rendering determines how an output image is constructed from a series of
+aligned input frames, and occurs in two stages: incremental rendering and
+Irani-Peleg rendering.  Additional rendering options include exposure
+registration, certainty-weighted rendering, spatial extension, range extension,
+scaling, and bayer pattern specification.  Experimental options for video
+stream processing are also available.
+
+
Incremental Rendering

+
+
The incremental renderer uses configurable rendering
+chains to determine the output image.  It can increase resolution and
+reduce aliasing, but it cannot reduce blur.
+
+
Irani-Peleg Rendering

+
+
The Irani-Peleg renderer uses configurable point-spread
+functions to model blur, which is then reduced by an iterative
+backprojection technique.  For iteration defaults, see the  default settings page.
+
+
+--ips <i>         Run <i> iterations.
+

+
+
Exposure Registration

+
+
By default, ALE adjusts an exposure model to minimize differences in tone
+between frames.  The option --exp-noregister indicates that
+exposure should be assumed uniform across all frames.  In this case, no
+adjustment is performed.

+
+
+--exp-register    Register exposure between frames.  [default]
+--exp-noregister  Assume uniform exposure across all frames.
+

+
+
Certainty-weighted Rendering

+
+
The exposure model in ALE includes an associated certainty function, which
+quantifies the reliability of sensor measurements.  By default, this function
+is raised to the zeroth power, to obtain uniform certainty for all measurements.
+To specify a different certainty exponent, the option --cx can be
+used.  This option is best used in combination with --exp-extend
+(see below) and --ips.  For defaults, see the 
+default settings page.
+
+
+--cx <x>          Render with certainty exponent <x>
+--no-cx           Render with uniform certainty.
+

+
+
Scale factor

+
+
Rendering with a larger scale factor results in image output of the specified
+larger scale.  Larger scales can improve alignment precision and output image
+quality, but can also increase alignment and rendering times.
+
+
+--scale=x         Scale images by the factor x (where x is at least 1.0)
+

+
+
Image extents

+
+
The --extend option records pixel data that falls outside of the region of the
+first frame in the sequence.  This can be useful for providing additional
+alignment constraints or creating panoramic image mosaics.  (For mosaics, see
+also the description of the --follow option in the alignment section.)
+
+
+--extend          Increase image extents to accommodate all pixel data.
+--no-extend       Don't increase extents; crop to original frame. [default]
+

+
+
Exposure extents

+
+
By default, ALE restricts the output range to that of the original frame.
+To adjust the output range to accommodate the ranges of all input frames,
+specify --exp-extend.  For defaults, see the 
+default settings page.
+
+
+--exp-extend      Extend range to include all calculated values.
+--exp-noextend    Restrict to the original frame's range.
+

+
+
Bayer pattern specification

+
+
Many cameras sample only one color channel per output pixel.  To ignore the
+other channels, a bayer pattern can be specified.  In versions prior to 0.7.3,
+device-specific bayer patterns override the command-line specification.  In
+version 0.7.3 and later, the reverse holds.
+
+
+--bayer <b>       Set default bayer pattern to <b>, one of:
+                    (clockwise from top left pixel)
+                      rgbg      Red-green-blue-green
+                      gbgr      Green-blue-green-red
+                      grgb      Green-red-green-blue
+                      bgrg      Blue-green-red-green
+                      none      RGB-RGB-RGB-RGB
+                  Default is none or device-specific.
+

+
+
Video stream processing (Experimental)

+
+
If a sequence of frames represents a video stream, then, in addition to
+producing a single output image, ALE can also produce one or more sequences of
+processed frames, corresponding to one or more occurrences of the
+--visp option.  This option has its own associated scaling option,
+as well as an option to show excluded regions as dimmed wherever possible.

+
+
+--visp <args>     Process a video sequence.
+                     <args> are:
+                         <chain> <stabilization-type> <prefix> <suffix>
+                     <chain> is an incremental rendering chain.
+                     <stabilization-type> is one of:
+                         ma:<x>     Moving average over 2*<x> + 1 frames
+                         sf:<x>     Stabilize to single frame number <x>
+                         identity   Same as ma:0
+                     <prefix> is an output file prefix
+                     <suffix> is an output file suffix
+--visp-scale=<x>  Use scale <x> for VISP output.  (default is 1.0)
+--exshow          For single-invariant chains, show --ex regions dimmed.
+

+
+
Video stream processing example

+
+
To mimic the behavior of repeated applications of the 0.6.0
+--replace option over a sequence of frames, the following
+--visp option could be used.
+
+
+--visp last:nex:triangle:2 sf:0 frame .jpg
+

+
+
For better filtering, the following option could be used instead:
+
+
+--visp last:nex:sinc*lanc:6 sf:0 frame .jpg

ALE Point Spread Functions

+
+
The ALE Irani-Peleg renderer uses a point-spread function to model the optical
+and electronic properties of the capture device used.  The PSF can be specified
+in terms of one linear and one non-linear component.
+
+
PSF specification

+
+
The PSF can be explicitly specified by using one or both of the psf options.
+
+
+--lpsf <p>        Set linear colorspace point-spread function to <p>
+--nlpsf <p>       Set non-linear colorspace point-spread function to <p>
+

+
+Available explicit point-spread functions are as follows:
+
+
+box=<d>           Set the PSF to a box filter with diameter <d>.
+circle=<d>        Set the PSF to a circular filter with diameter <d>.  [ALE 0.7.1 and later.]
+stdin             Specify a custom filter at runtime.
+stdin_vg          stdin with vertically-oriented gaps after every 8th pixel.
+<p>+<p>           Summation of two functions
+<p>^<p>           Convolution of two functions.  [ALE 0.7.3 and later.]
+<n>*<p>           Multiplication by a scalar <n>.  [ALE 0.7.3 and later.]
+

+
+If a device is known to ALE, then its PSF can be implicitly set with the
+--device option.  (See the device page
+for more information.)  If a device is not specified, then the default linear
+PSF component is box=1.  The non-linear PSF component is disabled
+by default.
+
+
Determining the PSF

+
+
The PSF can be approximated based on images of known scenes.  The ALE source
+distribution includes an experimental script that numerically approximates the
+PSF in this way (d2/render/psf/ale-psf-calibrate).  Other, more
+efficient methods for approximating the PSF are likely possible, however.

ALE 3D Scene Reconstruction

+
+
In general, 3D modeling of scenes may allow handling of cases that per-frame
+projective transformations do not allow, such as registering frames having
+different viewpoints over a non-flat or specular scene, or recovery of depth
+from frames having different viewpoints.  ALE's implementation of 3D scene
+reconstruction is considered experimental in versions prior to 0.8.3.
+
+
Models

+
+
The method of modeling used in 0.8.2 and later is spatial subdivision based on
+regions of interest, followed by iterative update of the estimated occupancy
+and color of each region of interest.  (For a general discussion of occupancy,
+see Hans Moravec's work on depth recovery.)  In 0.8.1, the method of modeling
+is decomposition and deformation of a surface.  In earlier versions, a
+per-frame, per-pixel model of depth is used.
+
+
Recovered Color and Depth Output

+
+
The color and depth output options provide a reconstruction of the scene as
+viewed from a particular frame's vantage point, or from an arbitrary camera
+view [0.8.2 and later].  In 0.8.2 and later, normalization of output values by
+accumulated occupancy can optionally be disabled for unfiltered views.  Version
+0.8.3 adds support for options --et and --3dpx, which can be useful for 3D
+cropping applications.  --et specifies the minimum accumulated weight required
+for a pixel to be defined, allowing refinements of crops based on clip planes
+(--rc and --fc) established prior to scene
+reconstruction, whereas --3dpx specifies a region of space to be removed 
+after scene reconstruction.  0.8.3 uses depth image pixels to determine such spatial regions,
+leaving the pixels undefined, whereas 0.8.4 removes scene geometry prior to
+rendering, allowing rendering of background objects after the foreground has been removed.
+
+

+--occ-norm        Normalize output with accumulated occupancy.          [default]     [0.8.2 and later]
+--occ-nonorm      Don't normalize output with accumulated occupancy.                  [0.8.2 and later]
+--et <x>          Set encounter threshold <x> for defined pixels.  [default is 0]     [0.8.3 and later]
+--3dpx <args>     Exclude a specified spatial volume following full-scene             [0.8.3]
+                  reconstruction, assuming a single depth at each point
+                  in the output.  <args> are:
+                         <xmin> <xmax> <ymin> <ymax> <zmin> <zmax>
+--3dpx <args>     Exclude a specified spatial volume following full-scene             [0.8.4 and later]
+                  reconstruction.  <args> are:
+                         <xmin> <xmax> <ymin> <ymax> <zmin> <zmax>
+

+
+
Filtering [0.8.4 and later]

+
+Version 0.8.4 adds support for filtering color values from the inputs to
+produce final color renderings.  This is now the default.  Determining surface
+depth and gradient for filtering the inputs draws from a set of depth pixels
+within a disc whose radius can be specified with the --3d-dmr and --3d-fmr
+options.
+
+Filtering color from views distributed on a disc (about the camera origin) of
+specified aperture allows simulation of focus effects; such effects can be
+controlled with the --focus option.
+
+
+--3d-filter       Use filtering for 3D color output.                    [default]
+--3d-nofilter     Don't use filtering for 3D color output.
+--3d-dmr <x>      Set radius for filtering median depth to <x>        [default 0]
+--3d-fmr <x>      Set radius for filtering median diff to <x>         [default 0]
+--focus <ft> <op> Create focus region with type <ft> and options <op>:
+                     Focus type:
+                        d <d>           focus at distance <d>
+                        p <x> <y>       focus at point (x, y)
+                     Space-separated options may include zero or more of:
+                        ci=<ci>  camera index               [default 0]
+                        fr=<fr>  focal range                [default 0]
+                        ht=<ht>  horizontal tilt gradient   [default 0]

+                        sd=<sd>  start depth                [default 0]

+                            pixel     per pixel
+                        fs=<fs>  focal statistic, one of:
+                            mean      mean of views           [default]
+                            median    median of views
+

+
+
+
Camera parameter adjustment

+
+
In versions 0.8.1 and later, camera parameters can be adjusted according to
+control points to decrease the error between points in different frames.
+Perturbation bounds for adjustment can be specified, including an additional
+upper bound on view angle perturbation, and a stereo threshold can be set for
+discarding control points after adjustment is complete.  An initial camera view
+angle can also be specified.  Versions 0.8.2 and later allow calculation of
+error by median rather than mean, and also allow disabling of adjustment of
+orientation and/or position.
+
+
+--view-angle <x>  Set the initial diagonal view angle to <x> degrees.
+                     (Default is 43.7 degrees or device-specific.)
+--cpp-upper=<x>   Set upper bound <x> for camera parameter perturbation,           [0.8.1 and later]
+                  in pixels or degrees [default is 32]                            
+--cpp-lower=<x>   Set lower bound <x> for camera parameter perturbation,           [0.8.1 and later]
+                  in pixels or degrees [default is 0.125]                    
+--va-upper=<x>    View-angle perturbation upper bound in degrees  [default is 32]  [0.8.1 and later]
+--st <x>          Control point stereo threshold is <x> pixels.    [default is 4]  [0.8.1 and later]
+--cpp-err-mean    Use RMS error to determine camera parameters.         [default]        [0.8.2 and later]
+--cpp-err-median  Use median error to determine camera parameters.                       [0.8.2 and later]
+--vp-adjust       Adjust the view point                                 [default]        [0.8.2 and later]
+--vp-noadjust     Do not adjust the view point                                           [0.8.2 and later]
+--vo-adjust       Adjust the view orientation                           [default]        [0.8.2 and later]
+--vo-noadjust     Do not adjust the view orientation                                     [0.8.2 and later]
+

+
+
Transformation data files [0.8.2 and later]

+
+Transformation data file options allow reading and writing of camera position,
+orientation, and view angle information.
+
+
+--3d-trans-load=x Load initial transformation settings from file x                       [0.8.2 and later]
+--3d-trans-save=x Save final transformation data in file x                               [0.8.2 and later]
+

+
+
Transformation data file format [0.8.2 and later]

+
+
The transformation data file uses the following format, starting with a version
+command, and then describing view angle and euclidean transformation of each
+frame in turn:
+
+
+W 0
+V <view angle>
+E <width> <height> <X> <Y> <Z> <P> <Y> <R>
+V <view angle>
+E <width> <height> <X> <Y> <Z> <P> <Y> <R>
+.
+.
+.
+V <view angle>
+E <width> <height> <X> <Y> <Z> <P> <Y> <R>
+

+
+
Model costs [0.8.1 only]

+
+
After the cameras are adjusted, a 2D surface is decomposed and deformed to
+reduce local cost measures, calculated from angles between neighboring
+triangles, edge lengths, and differences in color between different views.
+Multipliers for edge length and angle costs can be specified on the
+command line.

+
+
+--ecm <x>         Set edge length cost multiplier <x>.         [default is 0.001]  [0.8.1 only]
+--acm <x>         Set angle cost multiplier <x>.               [default is 0.001]  [0.8.1 only]
+

+
+
Model rules [0.8.2 and later]

+
+
In versions 0.8.2 and later, clip planes can be specified, and a color falloff
+exponent for pairwise occupancy estimation can be specified.  Larger exponents
+are more forgiving of color differences between pixels in different frames.
+In versions 0.8.3 and later, error contributions from cameras outside of the
+generating pair can be assigned non-zero multipliers (--tcem), the
+number of occupancy and color update iterations can be specified
+(--oui), the number of points in space generated for each pixel
+pair can be specified (--pa), and the type of frame pairings can
+be specified (--pc).
+
+
+--di-upper <x>    Decimate primary input resolution by at most 2^x [default is 0]  [0.8.4 and later]
+--di-lower <x>    Decimate input resolutions by at least 2^x       [default is 0]  [0.8.4 and later]
+--do-try <x>      Decimate output resolution by 2^x if possible    [default is 0]  [0.8.4 and later]
+--oc              Clip scene to output regions.                                    [0.8.4 and later]
+--no-oc           Do not clip scene to output regions.                  [default]  [0.8.4 and later]
+--fc <x>          Set front-clip to <x> (0 < x < 1)                [default is 0]  [0.8.2 and later]
+--rc <x>          Set rear-clip to <x> (1 < x < inf)             [default is inf]  [0.8.2 and later]
+--fx <x>          Set falloff exponent to <x>                      [default is 0]  [0.8.2 and later]
+--tcem <x>        Set third-camera error multiplier to <x>         [default is 0]  [0.8.3 and later]
+--oui <x>         Set occupancy update iterations to <x>          [default is 10]  [0.8.3 and later]
+--pa <x>          Set pairwise ambiguity to <x>                    [default is 3]  [0.8.3 and later]
+--pc <type>       Set the type of pairwise comparisons:                            [0.8.3 and later]

ALE Transformation Data Files

+
+Transformation data files are useful when performing alignment in several
+passes or refining rendering options, and are necessary for specifying
+barrel/pincushion distortion parameters.  They also offer a way to manually
+specify alignment when ALE cannot automatically align images.  
+
+
Multiple-pass alignment

+
+To align images in multiple passes, load the saved results of each previous
+pass, as follows:
+
+
+$ ale --trans-save=a.t <first pass arguments>
+$ ale --trans-load=a.t --trans-save=b.t <second pass arguments>
+$ ale --trans-load=b.t --trans-save=c.t <third pass arguments>
+.
+.
+.
+

+
+
Rendering option refinement

+
+To refine rendering options using the same alignment, first save the alignment
+for the first option set, and then load the saved alignment information with
+each subsequent option set, setting the perturbation upper bound to zero to
+prevent a new alignment pass from occurring:
+
+
+$ ale --trans-save=a.t <first option set>
+$ ale --trans-load=a.t --perturb-upper=0 <second option set>
+$ ale --trans-load=a.t --perturb-upper=0 <third option set>
+.
+.
+.
+

+
+
Alignment file syntax (version 2)

+
+There are two varieties of alignment file syntax that are both read and written
+by ALE 0.7.0.  The most basic of these is version 2.  Version 3 is slightly
+more complex, and is covered in the next section.
+
+At the highest level, version 2 transformation data files contain the following
+components: (a) a version command, and (b) a sequence of transformation
+commands, one for each supplemental frame.  Each line of text should contain at
+most one command, between which optional comments may be interspersed.  A
+transformation command can be Euclidean, projective, or default.  Euclidean and
+projective commands take several arguments, including the width and height of
+the supplemental frame.  Default commands take no arguments.  Commands are
+outlined in more detail below.
+
+
Version command

+
+
The version 2 version command is as follows:

+
+
+V 2
+

+
+
Euclidean commands

+
+
The structure of a Euclidean command is as follows:

+
+
+E <image width> <image height> <x-offset> <y-offset> <rotation-angle>
+

+
+
Projective commands

+
+
Projective commands map the four corners of the supplemental frame to four
+points in the rendering coordinate system:

+
+
+P <image width> <image height> <top-left-x> <top-left-y> <blx> <bly> <brx> <bry> <trx> <try>
+

+
+
Default commands

+
+Default commands can be explicitly written as follows:
+
+
+D
+

+
+Alternatively, if there are more frames than alignment commands (euclidean,
+projective, or default), then the last supplemental frames in the frame
+sequence will be assigned the default command.
+
+
Comments

+
+Comments can be inserted with the following syntax:
+
+
+# This comment extends to the end of this line.  I can write anything I want here.
+

+
+
Alignment file syntax (version 3)

+
+Version 3 syntax is required for specifying transformations for the original
+frame, and for specifying barrel/pincushion distortion parameters.  
+
+
In version 3, the first transformation command is associated with the
+original frame, instead of being associated with the first supplemental frame.
+Also, barrel/pincushion distortion commands can precede each projective,
+Euclidean, or default command.
+
+
Version command

+
+
The version 3 version command is as follows:

+
+
+V 3
+

+
+
Barrel/pincushion distortion command

+
+In version 3, barrel/pincushion distortion commands are supported.  Distortion
+is modeled as a transformation affecting the distance of image features from the
+image center.  The distorted distance is expressed as a polynomial function of
+the undistorted distance.  Zeroth and first order coefficients are fixed or
+automatically determined; additional coefficients can be specified explicitly,
+using the following syntax:
+
+
+B <n> <coefficient 2> <coefficient 3> ... <coefficient n+1>
+

+
+
Barrel/pincushion distortion commands should precede the projective, Euclidean,
+or default transformation command for the corresponding frame.

Alignment

+
+
Alignment compares each supplemental frame in the sequence with an intermediate
+incremental rendering known as the alignment reference image.  Based on this
+comparison, a transformation is assigned to the supplemental frame.  Many
+different transformations can be assigned before alignment of the frame is
+complete.
+
+
This manual page offers an overview of alignment options; linked from this
+page is a sub-page offering more detail on transformation
+data files.
+
+
Transformations

+
+
The variables used to adjust alignment are called transformations; they map
+points from the source image coordinate system to a target coordinate system
+(the rendering coordinate system).
+
+
ALE supports three transformation classes -- translational, euclidean, and
+projective -- as well as barrel/pincushion distortion correction.  The
+translational class applies only translations to the inputs, changing only the
+positions of images; the Euclidean class applies translations and rotations;
+and the projective class applies general projective transformations.
+Additionally, barrel/pincushion distortion correction can be applied to each
+frame.  The Euclidean class is most appropriate for use with scanners, or as a
+first pass for projective transformations.  The projective class and
+barrel/pincushion distortion correction are most appropriate for use with
+cameras.  Except when capturing flat scenes, ALE does not correct perspective
+changes, so movement of cameras should ideally be constrained so that no large
+translations occur.
+
+
Transformation Class Options

+
+
+--translation     Only adjust the position of images
+--euclidean       Adjust the position and orientation of images [default]
+--projective      Use projective transformations.  Best quality, but slow.
+

+
+For more information on barrel distortion correction, see the sub-page on 
+transformation data files.
+
+
Transformation data file options

+
+
Transformations used in alignment can be loaded from, or saved to, a transformation data file.  This can be useful when performing
+alignment in several passes, or when refining rendering options.  A
+transformation data file is required for barrel/pincushion distortion
+correction.
+
+
+--trans-load=x    Load initial transformation settings from file x
+--trans-save=x    Save final transformation data in file x
+

+
+
Alignment following

+
+
The --follow option hints that frames tend to be more closely aligned with
+adjacent frames in the sequence than with the original frame.  This hint can be
+useful even when initial alignment information is loaded from a file.
+
+
+--identity        Frames align closely with the original frame.  [default]
+--follow          Frames align closely with their immediate predecessor.
+

+
+
Match statistics

+
+
The match statistic indicates how well a transformed frame aligns with the
+alignment reference image; it is used to select or reject transformations
+during alignment.  After alignment of a particular frame is complete, ALE
+displays the corresponding final match statistic.  If the value is close to
+100%, then the frames are well aligned; very low values can indicate
+misalignment; but even frames that are very well aligned typically do not
+achieve 100% alignment.  For improving image quality, ALE works most
+effectively when match values are lower than 100%.
+
+
Match threshold

+
+
A match threshold can be specified; no images with final match statistics
+falling below this threshold will contribute to the final output.
+
+
+--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)
+

+
+
Alignment failure

+
+
When an image fails to meet the match threshold, a transformation is still
+assigned to the frame (e.g., for writing to a transformation
+data file).  The assigned transformation can be either the optimal
+alignment found (this is default) or the default transformation.
+
+
+--fail-optimal    Frames beneath threshold are aligned optimally.  [default]
+--fail-default    Frames beneath threshold keep their default alignment.
+

+
+
Alignment error metric exponent

+
+
The function calculated at each pixel to determine the match statistic is called
+the alignment error metric, and is of the form (a-b)x.
+The value x is called the error metric exponent, and is 2 by default.
+Larger numbers indicate that alignment will be more influenced by smaller
+image features.
+
+
+--metric=x        Set the alignment error metric exponent.       (2 is default)
+

+
+
Alignment Channel Options

+
+
In calculating the per-pixel error metric, there are three ways in which ALE
+can handle color channels.  By default, ALE adds the channels before
+calculating the match, but it can also be configured to rely solely on the
+green color channel, or to use all three channels separately.
+
+
+--align-all       Align images using all color channels
+--align-green     Align images using the green channel
+--align-sum       Align images using a sum of channels [default]
+

+
+
Monte Carlo Alignment

+
+
Aligning large images can take a very long time if all pixels are examined in
+determining the match statistic, so it is often desirable to examine a smaller
+subset of pixels.  The Monte Carlo alignment option allows this.  The number of
+pixels used is specified as a percentage, and smaller numbers usually mean
+faster, but less precise, alignment.  For defaults, see the 
+default settings page.
+
+
+--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
+--no-mc           Align using all pixels.
+

+
+
Alignment weight map

+
+
Typically, measured differences at each pixel in the alignment reference
+image contribute equally to the match statistic.  To weight pixels differently,
+a weight map can be used.  The scale of the map should correspond with that of
+the alignment reference image, and if the upper-left corner of the map does not
+coincide with the upper-left corner of the first frame in the sequence, then a
+non-zero offset should be specified to indicate the difference.  See also exclusion regions.
+
+
+--wm <f> <x> <y>  Use weight map image <f> at offset (<x>, <y>)
+

+
+
Frequency weighting

+
+
If ALE is compiled with FFTW support, then a high-pass-filtered version of
+the alignment reference image can be used to weight reference image pixels'
+contributions to the match statistic.  Frequency limiting can occur as a
+fraction of the highest horizontal frequency, the highest vertical frequency,
+or the highest average frequency.  Limit values should range between 0 (pass
+all) and 1 (pass none).  If any limit is assigned a value of 1, no alignment
+will occur, since all frequencies will have been excluded.  An output file can
+optionally be specified for high-pass filtered data.

+
+
+--fl <h> <v> <a>  High-pass filters: horizontal <h>, vertical <v>, average <a>.
+--flshow <o>      Write high-pass filtered data to file <o>.
+

+
+
Certainty weighting

+
+
Certainty weighting causes contributions to alignment error to be weighted
+by certainty values.

+
+
+--cw              Weight alignment error by certainty.
+--no-cw           Don't weight alignment error by certainty. [default]
+

+
+
Algorithmic weighting

+
+
This option writes the current alignment reference image and definition map
+to specified files, executes a specified program with these arguments, and then
+reads back alignment weights.  This option requires POSIX libraries, and
+requires that ALE have been built with POSIX support enabled.

+
+
+--wmx <e> <r> <d> Write reference <r>, definition <d>, execute `<e> <f> <d>`,
+                  read weights <r> back.
+

+
+
Perturbation

+
+
The perturbation size determines the magnitude by which alignment parameters
+are changed.  The size is initially set to be large, allowing large changes in
+alignment to be evaluated, and is reduced as the locally optimal alignment is
+found for each size.  When this size drops below a specified lower bound, the
+frame is considered to be aligned.
+
+
Perturbation bounds

+
+
These options determine the upper and lower bounds for perturbation size.  The
+perturb-upper and perturb-lower bounds apply to rotation (in arclength),
+translation (in pixels), and the movement of the boundaries of a projected
+frame (in pixels).  By appending the '%' character, values may optionally be
+specified as a percentage of the number of pixels in the smallest image
+dimension.  The rot-upper bound disables rotational perturbation above a
+certain perturbation size (in degrees).  To disable alignment, set
+perturb-upper to zero.
+
+
+--perturb-upper=x Perturbation upper bound pixels/arclength    (14% is default)
+                     ('x%' uses a fraction of the smallest image dimension.)
+--perturb-lower=x Perturbation lower bound pixels/arclength   (.125 is default)
+                     ('x%' uses a fraction of the smallest image dimension.)
+--rot-upper=x     Rotation-specific upper bound in degrees    (32.0 is default)
+

+
+
Barrel/pincushion distortion adjustment multiplier and rate

+
+
When using barrel/pincushion distortion parameters, any frame-to-frame
+adjustments to these parameters are made in a manner dependent on the
+perturbation size.  A multiplier, the barrel distortion adjustment multiplier,
+is used to determine the perturbation of these parameters, based on the generic
+perturbation size.  Additionally, the frame-to-frame rate of change of each
+barrel distortion parameter can be limited to a specified maximum.  To disable
+frame-to-frame adjustment of barrel/pincushion distortion parameters, set
+bda-mult to zero.  Setting bda-rate to zero disables rate limitation.
+
+
+--bda-mult=x      Barrel distortion adjustment multiplier   (0.0001 is default)
+--bda-rate=x      Barrel distortion rate of change maximum  (0.0004 is default)
+

+
+
Level of detail

+
+
Alignment at large perturbation sizes is usually carried out on
+reduced-detail images.  To disable this, set lod-max to
+log2(perturb-upper).
+
+
+--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)
+

+
+
Perturbation Types (experimental)

+
+
Perturbations are normally performed in output image coordinates.  To perform
+perturbations in source image coordinates, specify --perturb-source.
+
+
+--perturb-output  Apply perturbations in output image coordinates. [default]
+--perturb-source  Apply perturbations in source image coordinates.
+

+
+
Global Searching

+
+
In cases where important image features do not have sufficient overlap using
+default alignment parameters (determined by --identity and
+--follow), a number of translations can be applied to the default
+parameters in order to find a new alignment starting point.  Since this process
+searches the entire region of the alignment reference image, it is called a
+global (as opposed to local) search.  To avoid misalignment, a minimum overlap
+area can be specified.  In versions 0.8.1 and later, the search type 'points'
+searches for a control point metric minimum.
+
+
+--gs <type>       Set global search to <type>, one of:
+                     local     Local alignment only [default]
+                     inner     Alignment reference image inner region
+                     outer     Alignment reference image outer region
+                     all       Union of inner and outer
+                     central   inner if below threshold or better; else, outer.
+		     points    Align by control points.  Ignores gs-mo.   [0.8.1 and later]
+
+--gs-mo <x>       Set <x> pixel min. overlap for global search. (16 is default)

Control Points  [0.8.1 and later]

+
+
Control points are used for 2D and 3D alignment, and to constrain 3D scene
+models.  Control point data is loaded from a control point file.  Scripts to
+generate and manipulate control point files are included in the
+scripts directory of the source distribution; the file
+specification is outlined in the final section below.
+
+
Loading a Control Point File

+
+The --cpf-load= option is used to load data from a control point file.
+
+
+--cpf-load=<f>    Load control point data from file <f>   [0.8.1 and later]
+

+
+
Control Point File Format (version 0)

+
+The version 0 control point file format consists of a version command followed
+by a sequence of control points, with one control point per line of the file.
+
+
+V 0
+Control Point 1
+Control Point 2
+Control Point 3
+.
+.
+.
+

+
+
Control points can be one of three types:

+
+
Type A control points

+
+Type A control points specify a sequence of 2D points, one for each frame,
+where each point is specified as a pair of floating point numbers.  If there is
+no data for a frame, then "nan" should be specified.  E.g.:
+
+
+A 20  30  nan nan 10  10  10  15
+A 23  22  25  25  nan nan nan nan
+

+
+
Type B control points

+
+Type B control points specify a 3D coordinate.  E.g.:
+
+
+B 10 30 -400
+B 10 15 -425
+

+
+
Type C control points

+
+Type C control points specify both 2D and 3D data.  There is a single 3D point
+specified, as well as one 2D point for each frame.  The 3D point appears at the
+end of the line.  E.g.:
+
+
+C 20  30  nan nan 10  10  10  15  10 30 -400
+C 23  22  25  25  nan nan nan nan 10 15 -425

ALE Default Settings

+
+
ALE offers five different default settings, each of which emphasizes
+image quality, speed, or some other rendering characteristic, as follows:

+
+
+--q0              Low quality, high speed. [default]
+--qn              Low noise, moderate speed.
+--q1              Moderate quality and speed.
+--q2              High quality, low speed.
+--qr              Range-extended high quality.
+

+
+
These settings specify defaults for other options: --dchain, --achain,
+--mc, --ips, --exp-extend, and --cx.  For
+more information about these options, see the alignment and rendering
+manual pages.  Details regarding these defaults are provided in the following sections.
+
+
High speed (--q0)

+
+--q0 emphasizes speed over image quality.  This option is default, and
+sets other options' defaults as follows:
+
+
+   --dchain fine:box:1,triangle:2
+   --achain triangle:2
+   --mc 30
+   --ips 0
+   --exp-noextend
+   --no-cx
+

+
+
Low noise (--qn)

+
+--qn emphasizes low noise over resolution and rendering speed, and
+sets the following defaults:
+
+
+   --dchain sinc*lanc:6
+   --achain sinc*lanc:6
+   --mc 50
+   --ips 0
+   --exp-noextend
+   --no-cx
+

+
+
Balanced quality and speed (--q1)

+
+--q1 balances image quality and rendering speed, offering higher
+resolution than --qn.  In versions 0.8.1 and later, this option
+uses median values, which can be very memory-intensive to calculate.  The
+following defaults are used in versions 0.8.1 and later:
+
+
+   --dchain median:fine:sinc*lanc:8,triangle:2  [0.8.1 and later]
+   --achain triangle:2                          [0.8.1 and later]
+   --mc 50
+   --ips 0
+   --exp-noextend
+   --no-cx
+

+
+In 0.8.0, the following defaults are used:
+
+
+   --dchain fine:sinc*lanc:6,sinc*lanc:6        [0.8.0]
+   --achain sinc*lanc:6                         [0.8.0]
+   --mc 50
+   --ips 0
+   --exp-noextend
+   --no-cx
+

+
+
High quality (--q2)

+
+
--q2 favors image quality over rendering speed, offering greater
+emphasis for high-frequency details than --q0, --qn,
+or --q1.  It depends on the --lpsf and
+--nlpsf options, which can be set indirectly via the
+--device option.  (More information about these options can be
+found on the PSF and device pages.)  --q2
+sets the following defaults:
+
+
+   --dchain sinc*lanc:8
+   --achain sinc*lanc:8
+   --no-mc
+   --ips 4
+   --exp-noextend
+   --no-cx
+

+
+
Range extension (--qr)

+
+
--qr is similar to --q2, but offers improved
+rendering when input images have been taken with unequal exposures.  In other
+cases, it might exacerbate noise in light and dark regions, and so should not
+be used.  This option sets the following defaults:
+
+
+   --dchain sinc*lanc:8
+   --achain sinc*lanc:8
+   --no-mc
+   --ips 6
+   --exp-extend
+   --cx 0.7

ALE Devices

+
+
Device specification is optional.  Specifying a device allows automatic
+determination of point-spread functions,
+refinement of the correspondence between incident light and pixel values (e.g.
+power law), and refinement of certainty calculation.  
+
+
+--device <d>      Set the capture device to <d>.
+

+
+
Available devices are as follows:

+
+
+
canon_300d_raw_linearCanon 300D (Digital Rebel) raw, linear data.
+
canon_300d_raw_linear+50mm_1.4Canon 300D with EF 50mm f/1.4 lens, unspecified aperture.
+
canon_300d_raw_linear+50mm_1.4@1.4Canon 300D with EF 50mm f/1.4 lens, aperture 1.4.
+
canon_300d_raw_linear+50mm_1.8Canon 300D with EF 50mm f/1.8 lens, unspecified aperture.
+
canon_300d_raw_linear+85mm_1.8Canon 300D with EF 85mm f/1.8 lens, unspecified aperture.
+
ov7620_raw_linearOmniView OV7620 in raw RGB, linear mode.
+
xvp610_640x480IBM PC Camera Pro (XVP610) in 640x480 mode.
+
xvp610_320x240IBM PC Camera Pro (XVP610) in 320x240 mode.
+

+
+
These device options are described in more detail below.
+
+
Canon 300D (Digital Rebel)

+
+
Direct support for CRW files depends on the ImageMagick configuration, and
+may not be available on all platforms.  Dave Coffin's dcraw program, invoked with
+arguments -d -4, will produce a raw, linear PPM file suitable for use with this
+device configuration.  JPEG files produced by the 300D cannot be directly used
+as inputs for this configuration, since they are gamma-corrected rather than
+linear.

+
+
OV7620

+
+
Standard OV7620 drivers may not include options for setting raw RGB or linear
+modes.  Linux users may apply a driver patch to access
+these modes.  Setting the module option rgb_raw=2 places the camera
+into the desired mode.

+
+
XVP610

+
+
Users of XVP610 cameras and Linux may wish to apply a driver patch.  This version of ALE expects that this patch has been applied.

ALE Exclusion Regions

+
+
ALE offers exclusion regions as a way to disallow certain areas from being
+used in alignment and (optionally) rendering.  Spatial coordinates are
+expressed in the rendering coordinate system (prior to scaling).  In cases
+where the default transformation is used with the original frame, this is
+identical to the unscaled original frame coordinate system, taking the
+upper-left corner to be (0, 0).  Frame numbering begins with 0, which represents
+the original frame.
+
+
Rectangular Exclusion

+
+
All specified volumes are excluded from alignment (except where they affect
+the alignment reference image), and are excluded from rendering by default.
+(See the rendering chains page for
+information on how to ignore exclusion regions.)  Exclusion region syntax is
+as follows:
+
+
+--ex <args>       Exclude a specified volume.
+                     <args> are space-delimited horizontal,
+                     vertical, and frame limits:
+                         <xmin> <xmax> <ymin> <ymax> <fmin> <fmax>
+

+
+
Cropping

+
+Cropping excludes the spatial complement of an area over a specified set of
+frames.
+
+
+--crop <args>     Exclude the spatial complement of an area over a
+                  specified set of frames.  <args> are:

+
ALE File Output

+
+
File output options determine the format in which rendered images are written,
+and how frequently they are written.  Depending on the compilation options used,
+available file output options vary.
+
+
Output Color Depth

+
+
Output color depth of 8 or 16 bits of precision per color channel can be specified,
+for 24-bit or 48-bit color, respectively.  
+
+
+--8bpc            Write 8 bit per channel output [default]
+--16bpc           Write 16 bit per channel output
+

+
+
Extension-based file type determination

+
+
If ALE has been built with ImageMagick support, then the output file type can
+be determined automatically by file extension.  This is the default behavior
+for ImageMagick builds.  The --auto flag explicitly specifies that
+the default behavior should be used; it generates an error on builds compiled
+without ImageMagick support.  
+
+
+--auto            Determine file type automatically
+

+
+
PPM Output

+
+
All builds of ALE support PPM output.  PPM can be written in plain (ASCII) or
+raw (binary) format.  If ALE has been built without ImageMagick support, or if
+the file type cannot be automatically determined by file extension, then raw
+PPM output is used by default.
+
+
+--raw             Write raw PPM output
+--plain           Write plain PPM output
+

+
+
Incremental Output

+
+
By default, ALE writes intermediate results periodically throughout the rendering
+process.  This behavior can be disabled, however, so that output is written only
+after rendering is complete.
+
+
+--inc             Produce incremental output.  [default]
+--no-inc          Don't produce incremental output.
+

+
+
Undefined Values [0.8.3 and later]

+
+
By default, ALE colors undefined values black.  To assign nearest-neighbor colors
+to undefined pixels, the --def-nn option can be used.  This option is only
+available in versions 0.8.3 and later.
+
+
+--def-nn <R>      Use nearest-neighbor defined values within             [0.8.3 and later]
+                  radius <R>, zero outside.  Default radius is 0.

ALE 0.8.x User Manual

+
+
Purpose

+
+
This page summarizes program operation and command-line usage for ALE
+versions 0.8.0 through 0.8.4.  Features specific to a particular version
+are annotated (e.g.  [ALE 0.8.1 and later]).
+
+
Manual pages linked from this section describe default
+settings, file output, alignment, rendering, exclusion regions, control points, user interfaces, devices, and 3D scene reconstruction.
+
+
For more information on ALE, see the ALE Home Page.
+
+
Parameter Meta-syntax

+
+
+
+
+
+
+
+
+
+
+
+
+
 <foo>A required parameter called foo.
[<foo>]An optional parameter called foo.
+
[<foo>]*Zero or more parameters foo.
+

+
+
Command-line syntax for Image Processing

+
+
The following command-line invocation can be used to process a series of
+frames into an output file:
+
+
ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file>

+
+
Option Arguments

+
+
Certain basic modes of operation, emphasizing image quality, speed, or other
+rendering characteristics, are now established in the form of default settings.
+
+
Other options are outlined in the manual pages describing file output, rendering, alignment, exclusion
+regions, devices, user interfaces,
+and 3D scene reconstruction.
+
+
Image Files

+
+
ALE can be configured at compile time to use one of two different file
+handlers.  Execute 'ale --version' to determine which file handler is being
+used.  The table below outlines the supported formats for each file handler.

+
+
+

+
+
+
+
+
+
+
+
Version MessageFile Types Supported

+
File handler:     ImageMagick

+		
+Input and output files can be any of the formats supported by
+ImageMagick.
+

+
File handler:     PPM

+		
+Input files must be PPM, and output files are written as PPM.
+

+

+
+
Note that many external programs, including ImageMagick's command line utilities, can be used to
+convert between PPM and other formats.

+
+
See the README included in the source distribution of ALE for more information about
+compile-time configuration of file handlers.

+
+
Command-line syntax for Version Information

+
+
The following command-line invocation can be used to print version
+information and build options:
+
+
ale --version

+
+The following is sample output from this invocation:
+
+
+ALE Version:      0.8.4
+File handler:     ImageMagick
+Color data:       SINGLE
+Coordinate data:  SINGLE

EPPM Files

+
+
EPPM is an extension to the PPM file format that allows specification of
+metadata.  The header of an EPPM file conforms to the following template:
+
+
+P6#E
+# Tag1: Value
+# Tag2: Value
+# Tag3: Value
+# .
+# .
+# .
+Width Height Maxval
+Data
+

+
+
Tags recognized by ALE are outlined below.
+
+
Black level

+
+
The black level tag specifies a value that should be subtracted from
+all pixels in order to achieve linearity.  A modified version of dcraw (darcs repository) can be used to generate files
+containing this tag.
+
+
+# Black-level: <value>
+

+
+
Exposure tags

+
+
Exposure tags can be used for determining tonal registration through
+specification of shutter speed, aperture, and ISO sensitivity (or gain).
+
+
+# Shutter: <value>
+# Shutter: 1/<value>
+# Aperture: <f-number>
+# ISO: <value>
+# Gain: <value>
+

ALE Rendering Chains

+
+
The ALE incremental renderer is configured using rendering chains.  Rendering chains are
+constructed hierarchically from: invariants, SSFEs (scaled sampling filters
+with exclusion), SSFs (scaled sampling filters), and sampling filters.  Each of
+these components is described in a section below.  Defaults are outlined in the
+final section.
+
+
Chains

+
+
The chain is the top level of the rendering chain hierarchy, and is composed of a
+sequence of invariants.  Syntactically, a chain is specified as a number of
+invariants separated by commas:
+
+

+invariant1,invariant2,invariant3,...,invariantn
+

+
+
Each rendered pixel is assigned a value at the first invariant whose weight
+exceeds the weight threshold, or otherwise at the last invariant in the sequence.
+
+
Chain Options

+
+
+--wt <w>          Set weight threshold for defined pixels [default is 0.8 in v0.8.0; 0.1 in v0.8.1 and later]
+--dchain <g>      Use chain <g> to render the default output.
+--ochain <g> <o>  Use chain <g> to render output file <o>.
+--achain <g>      Use chain <g> to render the alignment reference image.
+--3d-chain <g>    Use chain  by default to render 3d output.  [0.8.4 and later]
+
+

+
+
Chain Examples

+
+
+             triangle:2                           ALE 0.6.0 merging (roughly)
+             fine:box:1                           Drizzling (roughly)
+             fine:sinc*lanc:8                     High-frequency preservation
+             last:nex:sinc*lanc:8                 Useful for video stabilization
+             fine:box:1,triangle:2                Multi-resolution rendering
+             fine:sinc*lanc:8,sinc*lanc:8         Multi-resolution rendering
+

+
+
Invariants

+
+
Invariants determine whether the rendered pixel value should be taken from a
+single frame, or from an average of all frames.  If from a single frame, it can
+be the first, last, minimal, or maximal pixel value.  Averages include mean
+and, in versions 0.8.1 and later, the median.  By default, the mean is used.
+(Note that using the median value may require allocation of a quantity of
+memory linear in the number of frames.)  The syntax is as follows:
+
+

+
+
+
Syntax
   
Description
avg:<SSFE>Mean value
+
median:<SSFE>Median value  [0.8.1 and later]
+
max:<SSFE>Maximum value
+
min:<SSFE>Minimum value
+
first:<SSFE>First value
+
last:<SSFE>Last value
+
<SSFE>Same as avg:<SSFE>
+

+

+
+
Scaled Sampling Filter with Exclusion (SSFE)

+
+
SSFEs qualify SSFs, indicating whether exclusion regions should be honored.
+
+

+
+
+
Syntax
   
Description
ex:<SSF>Honor exclusion regions
+
nex:<SSF>Don't honor exclusion regions
+
<SSF>Same as ex:<SSF>
+

+

+
+
Scaled Sampling Filter (SSF)

+
+
SSFs indicate whether filtering should occur at the resolution of the output
+image, or at the minimum of input and output image resolutions.  The former prevents loss
+of details; the latter prevents aliasing.
+
+

+
+
+
Syntax
   
Description
fine:<SF>Filter at full output image resolution
+
coarse:<SF>Filter at minimum resolution
+
<SF>Same as coarse:<SF>
+

+

+
+
SSF Options

+
+--afilter <s>     Use SSF <s> to interpolate points in alignment.
+

+
+
Sampling Filter (SF)

+
+
SFs are used to limit bandwidth.  Primitive functions and pointwise multiplication of these
+functions (windowing) are available.
+
+

+
+
+
+
Syntax
   
Description
sincSinc filter: (sin πx) / (πx)
lanc:<x>Lanczos, diameter x.
+
triangle:<x>Triangle, diameter x.
+
box:<x>Box, diameter x.
+
zeroZero function
+
<f>*<f>Pointwise multiplication (windowing)
+

+

+
+
Defaults

+
+
ALE defaults are as follows:

+
+
+                     dchain         Varies by default setting
+                     achain         Varies by default setting
+                     afilter        internal (approximates triangle:2)

+
ALE Rendering

+
+
Rendering determines how an output image is constructed from a series of
+aligned input frames, and occurs in two stages: incremental rendering and
+Irani-Peleg rendering.  Additional rendering options include exposure
+registration, certainty-weighted rendering, spatial extension, range extension,
+scaling, and bayer pattern specification.  Experimental options for video
+stream processing are also available.
+
+
Incremental Rendering

+
+
The incremental renderer uses configurable rendering
+chains to determine the output image.  It can increase resolution and
+reduce aliasing, but it cannot reduce blur.
+
+
Irani-Peleg Rendering

+
+
The Irani-Peleg renderer uses configurable point-spread
+functions to model blur, which is then reduced by an iterative
+backprojection technique.  (For iteration defaults, see the  default settings page.)  In versions 0.8.1 and
+later, using the median correction value can be specified.  By default,
+the mean correction value is used.
+
+
+--ips <i>         Run <i> iterations.
+--ip-mean         Use the mean correction [default]   [0.8.1 and later]
+--ip-median       Use the median correction           [0.8.1 and later]
+

+
+
Exposure Registration

+
+
By default, ALE adjusts an exposure model to minimize differences in tone
+between frames.  The option --exp-noregister indicates that
+exposure should be assumed uniform across all frames.  In this case, no
+adjustment is performed.  The option --exp-meta-only indicates
+that only exposure information included in the image files should be used for
+registration.  Currently, EPPM is the only type of exposure
+metadata supported by this option.

+
+
+--exp-register    Register exposure between frames.  [default]
+--exp-noregister  Assume uniform exposure across all frames.
+--exp-meta-only   Use only image metadata for registering exposure.
+

+
+
Color Adjustment [0.8.1 and later]

+
+
To adjust the color of the output image (e.g., for white balance) in
+versions 0.8.1 and later, the --exp-mult= option can be used.

+
+
+--exp-mult=c,r,b   Adjust all channels by <c>, red by <r>, and blue by <b>.  [0.8.1 and later]
+

+
+
Certainty-weighted Rendering

+
+
The exposure model in ALE includes an associated certainty function, which
+quantifies the reliability of sensor measurements.  By default, this function
+is raised to the zeroth power, to obtain uniform certainty for all measurements.
+To specify a different certainty exponent, the option --cx can be
+used.  This option is best used in combination with --exp-extend
+(see below) and --ips.  For defaults, see the 
+default settings page.
+
+
+--cx <x>          Render with certainty exponent <x>
+--no-cx           Render with uniform certainty.
+

+
+
Scale factor

+
+
Rendering with a larger scale factor results in image output of the specified
+larger scale.  Larger scales can improve alignment precision and output image
+quality, but can also increase alignment and rendering times.
+
+
+--scale=x         Scale images by the factor x, where x > 0.     (1 is default)
+

+
+
Image extents

+
+
The --extend option records pixel data that falls outside of the region of the
+first frame in the sequence.  This can be useful for providing additional
+alignment constraints or creating panoramic image mosaics.  (For mosaics, see
+also the description of the --follow option in the alignment section.)
+
+
+--extend          Increase image extents to accommodate all pixel data.
+--no-extend       Don't increase extents; crop to original frame. [default]
+

+
+
Exposure extents

+
+
By default, ALE restricts the output range to that of the original frame.
+To adjust the output range to accommodate the ranges of all input frames,
+specify --exp-extend.  For defaults, see the 
+default settings page.
+
+
+--exp-extend      Extend range to include all calculated values.
+--exp-noextend    Restrict to the original frame's range.
+

+
+
Bayer pattern specification

+
+
Many cameras sample only one color channel per output pixel.  To ignore the
+other channels, a bayer pattern can be specified.
+
+
+--bayer <b>       Set the bayer pattern to <b>, one of:
+                    (clockwise from top left pixel)
+                      rgbg      Red-green-blue-green
+                      gbgr      Green-blue-green-red
+                      grgb      Green-red-green-blue
+                      bgrg      Blue-green-red-green
+                      none      RGB-RGB-RGB-RGB
+                  Default is none or device-specific.
+

+
+
Video stream processing (Experimental)

+
+
If a sequence of frames represents a video stream, then, in addition to
+producing a single output image, ALE can also produce one or more sequences of
+processed frames, corresponding to one or more occurrences of the
+--visp option.  This option has its own associated scaling option,
+as well as an option to show excluded regions as dimmed wherever possible.

+
+
+--visp <args>     Process a video sequence.
+                     <args> are:
+                         <chain> <stabilization-type> <prefix> <suffix>
+                     <chain> is an incremental rendering chain.
+                     <stabilization-type> is one of:
+                         ma:<x>     Moving average over 2*<x> + 1 frames
+                         sf:<x>     Stabilize to single frame number <x>
+                         identity   Same as ma:0
+                     <prefix> is an output file prefix
+                     <suffix> is an output file suffix
+--visp-scale=<x>  Use scale <x> for VISP output.  (default is 1.0)
+--exshow          For single-invariant chains, show --ex regions dimmed.
+

+
+
Video stream processing example

+
+
To mimic the behavior of repeated applications of the 0.6.0
+--replace option over a sequence of frames, the following
+--visp option could be used.
+
+
+--visp last:nex:triangle:2 sf:0 frame .jpg
+

+
+
For better filtering, the following option could be used instead:
+
+
+--visp last:nex:sinc*lanc:6 sf:0 frame .jpg

ALE Point Spread Functions

+
+
The ALE Irani-Peleg renderer uses a point-spread function to model the optical
+and electronic properties of the capture device used.  The PSF can be specified
+in terms of one linear and one non-linear component.
+
+
PSF specification

+
+
The PSF can be explicitly specified by using one or both of the psf options.
+
+
+--lpsf <p>        Set linear colorspace point-spread function to <p>
+--nlpsf <p>       Set non-linear colorspace point-spread function to <p>
+

+
+Available explicit point-spread functions are as follows:
+
+
+box=<d>           Set the PSF to a box filter with diameter <d>.
+circle=<d>        Set the PSF to a circular filter with diameter <d>.
+stdin             Specify a custom filter at runtime.
+stdin_vg          stdin with vertically-oriented gaps after every 8th pixel.
+<p>+<p>           Summation of two functions
+<p>^<p>           Convolution of two functions.
+<n>*<p>           Multiplication by a scalar <n>.
+

+
+If a device is known to ALE, then its PSF can be implicitly set with the
+--device option.  (See the device page
+for more information.)  If a device is not specified, then the default linear
+PSF component is box=1.  The non-linear PSF component is disabled
+by default.
+
+
Determining the PSF

+
+
The PSF can be approximated based on images of known scenes.  The ALE source
+distribution includes an experimental script that numerically approximates the
+PSF in this way (d2/render/psf/ale-psf-calibrate).  Other, more
+efficient methods for approximating the PSF are likely possible, however.

ALE User Interfaces

+
+
ALE currently supports two user interface types.  The traditional interface
+is the stream interface, which produces only printing characters and
+whitespace.  If ALE is compiled with IOCTL support, additional information can
+be provided through the tty interface, which is default.
+
+
+--ui=<type>       Set user interface to <type>, one of:
+                     stream
+                     tty [default]

+V	0.9.0.3 2009-Mar-31
+
+o	Revise --version to include ImageMagick library information.
+
+o	Add ditz issue database and package document BUG-REPORTING.
+
+o	Refine warnings for 8-bit output when --16bpc (incl. default).
+
+o	Fix --16bpc default behavior.
+
+o	Fixed serious memory leak in alignment code, and less serious leaks.
+
+V	0.9.0.2 2008-Nov-05
+
+o	Fix 'exec -a' bashism in ale script, after this was reported by
+	Mihai Varzaru as being broken in Ubuntu 8.10.
+
+o	Update documentation makefile for better links compatibility.
+
+V	0.9.0.1 2008-Jun-13
+
+o	Use a pager (e.g., less) when displaying help.
+
+o	Add a man page, at the recommendation of Debian developer Ruben Molina.
+	The man page structure roughly follows that of Debian Iceweasel, GNU tar,
+	and the earlier ALE manual page for Debian by Nick Rusnov and Ruben
+	Molina.
+
+o	Add new algorithms for pixel assignment in multi-alignment, including
+	filling, least-size local selection, and global-best selection.
+
+o	Fix various multi-alignment bugs, including a bug causing increased
+	computational complexity for rendering, as well as offset and scaling
+	bugs.
+
+o	Modify --lod-max to --lod-preferred, add a dimension restriction
+	--min-dimension on level-of-detail, and make --lod-preferred=-3
+	and --min-dimension=10 default.
+
+o	Revise DejaGNU test suite for current option syntax, so that "make
+	check" now runs all tests.
+
+o	Do not attempt to handle --trans-{save,load} arguments as images in
+	the ale wrapper script.
+
+o	Add include  to ui/ui.h in an attempt to resolve Debian bug
+	#482765, reported by Marc Brockschmidt and noted by Ruben Molina.
+
+o	Include more information about scale cluster structures in the
+	logging ui.
+
+o	Add tonal registration by element to multi-alignment code.
+
+o	Add a minimum average certainty for registration of multi-alignment
+	elements.
+
+o	Modify ale script to tally thread statistics when the environment
+	variable ALE_COUNT_THREADS is set non-zero.
+
+V	0.9.0 2008-Apr-14
+
+o	Add skeletal web documentation to the documentation tree, in doc/web,
+	and revise this to consolidate more information on the front page.
+
+o	Implement an alignment technique allowing multiple alignments for a
+	single frame.  Handling parts of a frame separately to resolve
+	alignment issues (but using match thresholding to discard regions
+	instead of using multiple alignments) was suggested by Rob Stewart.
+
+o	Add --resident parameter, allowing explicit allocation of backing store
+	for (e.g., large) image data structures.
+
+o	Check for NaN in linearization and unlinearization in exposure_default,
+	as a possible fix for a segmentation fault reported by Bret Towe.
+
+V	0.8.11 2007-Nov-03
+
+o	Revise certain code for improved execution speed, including
+	disabling certain assertions and reducing calls to pow().
+
+o	Replace geometric-mean filtering of weight values with minimum-value
+	filtering, reducing calls to pow().
+
+o	Add fixed-point data types selectable at configuration time for
+	coordinate and color data, hence improving speed on certain embedded
+	platforms.  Use on phones was suggested by Wen Guihua.
+
+o	Revise incremental rendering code to store color values unnormalized by
+	weights.
+
+o	Revise multi-alignment options for the currently-considered
+	implementation.
+
+o	Eliminate NaN propagation that could lead to alignment failure in
+	certain cases, perhaps causing an alignment bug reported in earlier
+	versions by Gregory Maxwell.
+
+V	0.8.10.1 2007-Oct-04
+
+o	Change 'char *' referencing string literals to 'const char *'.
+
+o	Set perturbation multipliers to 1 in cases of a non-finite value.
+
+V	0.8.10 2007-Oct-02
+
+o	Add threading for d2::image::*scale_by_half() functions.
+
+o	Always rescale transformations for full detail after alignment is
+	complete.
+
+o	Make --lod-max=-4 default.
+
+o	Make default --dchain auto:triangle:2,fine:box:1,triangle:2, which
+	should produce better output during re-filtering than the previous
+	default.
+
+o	Revise re-filtering operation to use as a filter scale the distance
+	between nearest defined points in opposite axis-centered cones about
+	the point to be filtered.
+
+o	Update scale cluster structures and interpolation routines used in
+	alignment for calculating and storing certainty and weights; in 
+	particular, certainty of the input frame is now pre-calculated 
+	for multiple levels of detail.
+
+o	Add currently-unused skeletal code for non-linear level of detail
+	calculations.
+
+o	Revise Monte-carlo value to use a single static default, removing
+	dynamic behavior and certain associated support code, and applying the
+	sampling rate in a uniform manner to all levels of detail and all tonal
+	and spatial registration algorithms.
+
+o	Fix error in level-of-detail accounting in alignment code.
+
+o	Replace references to math.h with references to ale_math.h.
+
+V	0.8.9.1 2007-Aug-31
+
+o	Attempt to resolve certain 'always true' warnings reported by
+	Marius Schamschula on Mac OS 10.3.9 (PPC).
+
+o	Add macros for isinf() and isnan() in an attempt to resolve build 
+	failures reported by Marius Schamschula on Mac OS 10.3.9 (PPC).
+
+o	Resolve certain build errors occuring when configuring
+	--disable-threads, or when threads are unavailable.
+
+o	Remove instrumentation writing to 'lsimulated.png'.
+
+V	0.8.9 2007-Aug-25
+
+o	Set new defaults for --ips, --dchain, and --3d-dchain, and remove --q*
+
+o	Add rendering chain scaled sampling filter type auto:, implementing
+	re-filtering, with rough automatic filter size determination.
+
+o	Add an abstract domain decomposition threading class.
+
+o	Revise Irani-Peleg code for reduced memory and cpu use.
+
+o	Attempt to fix exclusion region handling after a bug report by 
+	Gregory Maxwell; other issues may remain.
+
+o	Fix handling of --ip-{mean,median}, resolving a bug noted by Gregory
+	Maxwell.
+
+o	Add wrapper script 'ale' for handling raw files and extracting Exif metadata.
+
+o	Allow any match when the threshold specified is neither positive nor zero.
+
+o	Update license to GPLv3.
+
+o	Various rendering bugfixes.
+
+V	0.8.8.1 2007-May-18

+o	Disable d2::gauss::cutoff definition after a build failure reported by
+	Marius Schamschula on an Intel Mac running 10.4.9 (gcc 4.0.0?).

+
+o	Include an incomplete implementation for multiple alignment region handling.
+
+o	Make --16bpc default.
+
+o	Add extents calculation to d2::render::ipc to limit the area examined during 
+	exposure re-estimation.
+
+o	Provide a new cache of fixed size for input images, defaulting to 256MB, 
+	adjustable via the --cache option.
+
+o	Add error statistics for calculating center of rotation and perturbation size
+	for alignment.
+
+o	Add loop avoidance for dynamic monte carlo alignment.
+
+o	Reduce --mcd-removal default to 10.
+
+o	Use synchronized instead of unsynchronized dynamic monte carlo removal checks.
+
+o	Disable --follow in the non-default case when perturbation size is zero.
+
+o	Make --no-inc default.
+
+o	Add 'defaults' global search option, and make this option default.
+
+o	Modify --gs-mo to allow specification as a percentage, and make 67%
+	default.
+
+o	Add user interface options --ui=log and --ui=quiet, with greater and

+
+o	Modify black level handling to always use linear values.
+
+o	Increase default barrel distortion multiplier and rate maximum to 2.0
+	and 8.0, respectively.

+o	Add UI update thread, in cases where threads are available.
+
+o	Allow file-scoped --gs and --gs-mo options.
+
+o	Ignore fex regions for nex SSFEs, resolving a bug noted by Gregory
+	Maxwell.
+
+o	Add --black option for specifying black level as a fraction of
+	saturation.
+
+o	Add --ev option for specifying ISO100-equivalent EV.
+
+o	Add breakdown of profiling information by perturbation size for local
+	alignment.
+
+V	0.8.7 2007-Mar-04
+
+o	Add a weight-limiting option to the Irani-Peleg renderer.
+
+o	Add incremental renderer mean invariant avgf:: weight-limited to
+	initial values.
+
+o	Modify d2::image::defined_scale_by_half() to use a geometric mean, so
+	that alignment at reduced level of detail will still work at larger
+	reductions when using non-zero certainty.
+
+V	0.8.6 2007-Feb-17
+
+o	In d2::align, use rotation about the frame center as an alternative
+	in cases where the sampling centroid is undefined.
+
+o	Modify d2::point::{neg,pos}inf() assertions to allow for isinf() 
+	implementations returning any non-zero value for any infinity.
+
+o	Re-adjust exposure in Irani-Peleg even when no non-linear stage is 
+	present.
+
+o	Adjust the default pixel definition threshold to account for the
+	certainty floor.
+
+o	Use a rudimentary, single-pass estimate-based certainty approach for
+	incremental rendering.
+
+o	When --cx is positive, use only certainty calculated from the simulated
+	scene for estimating tonal registration in Irani-Peleg passes.
+
+o	Remove --qr default setting, as certainty and range-extension now have
+	established general defaults.
+
+o	Change --cx to 1 by default.  Change --exp-extend to be disabled by
+	default.  Remove these flags from default settings.
+
+o	Update driver names to omit file type qualifiers, according to the
+	convention used in HJ Hornbeck's Nikon D50 device configuration patch.
+
+o	Add Nikon D50 device configuration.  (HJ Hornbeck)
+
+o	Update default settings according to time and image quality test
+	results.  fine:triangle:2, gauss:0.75, and combinations of these
+	filters were suggested by HJ Hornbeck.
+
+o	Revise incremental renderer to store unnormalized values, for better
+	handling of small weights, and eliminate the minimum contribution weight.
+
+o	Add inlining and pre-calculation to Irani-Peleg.  (HJ Hornbeck)
+
+o	Add gaussian sampling filter.  (HJ Hornbeck)
+
+V	0.8.5 2007-Jan-19
+
+o	Remove binaries and documentation sections from the readme, and
+	prune non-package documentation for source distributions.
+
+o	Make the --follow alignment option default.
+
+o	Add help text for argument scope.
+
+o	Modify rotational alignment search to rotate about the centroid
+	of the sample region.
+
+o	Revert 3D code to experimental status due to poor handling of
+	real image sets.
+
+o	Modify 3D code for slightly better handling of real image sets.
+
+V	0.8.5-pre3 2006-Nov-03
+
+/alignment
+o	Fix a potential nondeterminism bug due to undefined seed bits in the
+	random number generator.  (Fixes certain alignment failures.)
+
+/
+o	Modify default settings using Irani-Peleg rendering to use the
+	triangle:2 incremental rendering chain.
+
+o	Add dynamic monte carlo alignment, and make this default.
+
+o	Correct --exp-mult arg count.  (Gregory Maxwell)
+
+o	Allow file-scoped use of --perturb-upper.
+
+V	0.8.5-pre2 2006-Oct-25
+
+o	Modify d2::image::scale() to correctly handle offsets for
+	scale factors other than negative powers of two.
+
+o	Reformat most help text to fit a 79 column screen.
+
+o	Add option --profile to measure elapsed real time for 2D alignment
+	and rendering operations.
+
+o	Add support for POSIX threads to 2D alignment and rendering code.
+	(Adding multithreading support was first suggested by Jody (Joe)
+	Harris.  Testing of multithreaded code on multiprocessor hardware was
+	done by Gregory Maxwell.)
+
+V	0.8.5-pre1 2006-Oct-16
+
+o	Incorporate all existing ALE documentation within the source
+	tree, and license under GPL.  Begin migration of documentation,
+	including package documentation files, to a more flexible format.
+
+o	Modify ui_tty for correct operation under Hurd and DragonFly
+	consoles.  
+
+o	Revise README for autotools build and installation.
+
+o	Add file 'TODO', containing a to-do list for future releases.
+
+o	Add AUTHORS file, in accordance with the autotools packaging
+	standards.
+
+o	Revise Changelog name to autotools-approved ChangeLog
+
+o	Add NEWS file containing mailing list and Freshmeat announcement text
+	for versions through 0.8.4.  This file is required by autotools.
+
+o	Add options --f{ex,crop} for frame-coordinate exclusion regions.
+
+o	Add autotools-based configuration, build, and installation facilities,
+	replacing the earlier Makefile-based configuration and build process.
+
+o	Modify --mc to be a file-scoped option.
+
+o	Modify command-line interface to accept certain scope operators, and
+	to increase uniformity of syntax.
+
+o	Move input interface details, including option handling, messages,
+	and help information, to the ui/ subdirectory.
+
+o	In d3::scene, always use filler spaces when --pc all is specified.
+
+V	0.8.4 2006-May-14
+
+o	Fix build error noted by Gregory Maxwell and re-tag version.
+
+o	Add fine-grain UI updates for 3D operations when using ui=tty.  Reduce
+	tty UI status update frequency to at most once per second.
+
+o	Modify --3dpx to affect scene geometry rather than rendered
+	pixels.  In certain cases, this change should allow removal of objects
+	close to the camera, hence revealing objects further away.
+
+o	Add to the Makefile a HASH_MAP option that can be used to assign the
+	3D spatial info structure a hash map type instead of the standard STL
+	map type.  As this is likely to break things, it is currently
+	undocumented.  HASH_MAP=GNU seems to compile with g++ 4.0.x but
+	has not otherwise been tested.
+
+o	Add support for synthetic focus via the --focus option, including
+	focus with horizontal and vertical tilt.  Adding simulated focus
+	effects, including tilted and swung focal planes, was suggested by
+	Gregory Maxwell.
+
+o	Add support for filtering 3D output with --3d-filter.  This
+	is now the default behavior.  Add an option --3d-chain for selecting
+	the filter chain used for 3D output.  (See --hl and --hq for details.)
+
+o	Fix dimension comparison bug in d3::space::traverse::get_next_split().
+
+o	Implement an experimental approach to 3D subspace candidate selection;
+	this seems to perform poorly in most cases due to parallax effects.
+	See the source code for details.  (Option --subspace-traverse)
+
+o	Add adaptive weight decomposition to 3D occupancy algorithms.
+
+o	Move low-level code concerning scale and level-of-detail from
+	d3::scene to d3::pt.
+
+o	Move code concerning the nature of space from d3::scene to 
+	d3::space.
+
+o	Interpolate to generate smooth 3D depth output.
+
+o	Remove older 3D rendering code. 
+
+o	Add decimation options --di-upper, --di-lower, and --do-try for
+	reducing the complexity of 3D scene geometry, hence reducing the
+	number of operations required for occupancy updating.
+
+o	Add a script 'transform' for applying an inverse projective
+	transformation.  Recalculation of transformations was suggested by Rob
+	Stewart (ALE mailing list message, 2005-Dec-28).
+
+o	Add dates to the Changelog, using dates in comments in the download
+	page on the website for versions prior to 0.8.0, and using dates from
+	the darcs repository for versions 0.8.0 and later.
+
+
+V	0.8.3 2005-Dec-23
+
+o	Add option --3dpx to specify 3D regions to exclude during final
+	rendering, using a single depth for each pixel in each frame of
+	rendered output.  (Evaluates at the depth used in depth-rendering.)
+
+o	Add option --pc to specify which pairwise comparisons should be
+	performed.
+
+o	Add --et option to specify encounter thresholds.
+
+o	Clean up d3::scene to remove triangle-mesh code.
+
+o	Add an option --def-nn to allow definition of pixels in output images
+	to take values from neighboring pixels within a certain radius, in
+	cases where they would not otherwise be defined.
+
+o	Modify representation of 3D subspaces so that refined subspaces
+	are roughly cubical, and to allow refinements at multiple
+	resolutions.
+
+o	Fix bugs in 3D color and occupancy updating caused by bounding
+	box miscalculation.
+
+o	Add option --pa to set the number of point candidates accepted
+	for each pair of cameras (pairwise ambiguity).  The default
+	of 3 preserves existing default behavior.
+
+o	Add option --oui for determining occupancy update iterations.
+	The new default is 10, halving the previous default of 20.
+
+o	Add option --tcem for scoring point candidates by third-camera
+	views.  The default of 0 preserves existing default behavior.
+
+
+V	0.8.2 2005-Nov-22
+
+o	Add magical file 'dump:' for listing color values numerically
+	to stderr.
+
+o	Transition from a subdivisible triangle model to a subdivisible	
+	space model, using a rudimentary implementation of Hans Moravec's 
+	notion of occupancy.
+
+o	Add support for view and depth output from arbitrary cameras.
+
+o	Add clipping plane options for 3D modeling.
+
+o	Fix various bugs in control-point alignment reported by Gregory
+	Maxwell.
+
+
+V	0.8.1 2005-May-6
+
+o	Modify --q1 to use median-value incremental rendering.
+
+o	Add support for median-value incremental and Irani-Peleg rendering.
+	Using a statistic other than the mean was suggested by Scott Scriven
+	as a means of eliminating non-uniform artifacts.  Using the median
+	seems to improve performance on Scott Scriven's example sequences, as
+	well as on the scaled output of fine:sinc*lanc for sparse inputs.
+
+o	Move ale-psf-calibrate to a new scripts directory.
+
+o	Add support for using control points in 2D and 3D alignment, as well
+	as in 3D model construction.  New options include '--gs points',
+	'--cpf-load=', '--cpp-upper=', '--cpp-lower=', '--va-upper=', and
+	'--st'.
+
+o	Fix enumerator compile bugs noted by Gregory Maxwell and Tom Holroyd
+	to cause compilation failure under GCC 3.4.
+
+o	Add average magnitude comments to transformation data file output.
+
+o	Add a color adjustment option --exp-mult=.
+
+o	For 3D scene reconstruction, use a new unified surface model in place
+	of the depth-based multi-model approach used in 0.8.0.  The new model
+	is adjusted on the basis of edge, angle, and color measures.
+
+
+V	0.8.0 2005-Jan-12
+
+o	Add a flag --exp-meta-only which causes tonal registration to be
+	performed only on the basis of exposure metadata (e.g., data encoded
+	as EPPM extended attributes).  This approach was suggested by Gregory
+	Maxwell.
+
+o	Set image offsets in d2/render/combine.h.  This allows Irani-Peleg
+	rendering to work with --crop when the default rendering chain
+	includes more than one rendering invariant.
+
+o	Perform Irani-Peleg updating separately by channel instead of
+	using vector operations.  This allows divide-by-zero and other
+	conditions to be localized to particular channels.
+
+o	Modify the Irani-Peleg renderer to use estimate-based certainty.  This
+	seems to improve noise characteristics significantly.
+
+o	Write the results of tonal registration as a comment in the 
+	transformation data file.
+
+o	Add support for PPM with extended attributes (EPPM).  Attributes
+	handled specially include black level, shutter speed, aperture, and
+	ISO (or gain).
+
+o	Add experimental cost calculation routines to d3/scene.h.
+
+o	Modify euclidean alignment so that perturb-upper and perturb-lower
+	apply to rotational arclength.
+
+o	Fix an index variable bug in d2::image_bayer_ale_real::trigger().
+
+o	Modify d2::exposure one-sided certainty so that the 'one-sided'
+	condition only applies to bright (>50%) areas.  Applying it to dark
+	areas has no clear benefit, and an experiment by Gregory Maxwell
+	demonstrates that doing so can exacerbate noise.
+
+o	Modify d2::align to use unscaled input images when the scale factor
+	is larger than 1.0, or when a scaled_filter interpolant is being used.
+
+o	Modify d2::image::scale() to allow scale factors in the interval 
+	(0, 1), and modify the command-line interface and help text to reflect
+	this change.  --scale= now accepts all finite positive values.
+
+o	Add user interface options --ui=stream and --ui=tty.  The latter
+	includes more detailed status output when terminal width information
+	can be obtained (esp. when IOCTL=1 is set at compile time), and is the
+	new default.
+
+o	Move certain user interface elements to the source subdirectory ui/.
+
+o	Modify d2::render::ipc::_ip_frame_correct() so that exposure
+	re-estimation uses a ratio of weighted sums instead of a weighted
+	average of ratios.
+
+o	Modify d2::align::set_exposure_ratio() so that alignment 
+	weights and certainty values are taken into consideration.  
+
+o	Add a --cw option to weight alignment error by certainty values,
+	as suggested by Gregory Maxwell.  This allows the contributions of
+	pixels at maxval to be diminished, which can increase alignment
+	success in certain cases.
+
+o	Replace functions d2::incremental::{increase,decrease}_extents()
+	with new functions that take exclusion regions into account.  The new
+	functions should also fix a boundary-calculation bug reported by
+	Gregory Maxwell.
+
+o	Modify d2/render/ipc.h to handle exclusion regions more effectively.
+
+o	Add --crop argument, which excludes the spatial complement of a
+	specified area over a specified set of frames.  Gregory Maxwell notes
+	several advantages of internal over external crops, including
+	preserving knowledge of position in the uncropped frame, which among
+	other benefits allows natural handling of Bayer patterns.
+
+o	Modify rx_parameters in d2/render.h to use the ale_pos data type
+	instead of int.  This should allow exclusion regions to be calculated
+	more accurately.
+
+
+V	0.7.3 2004-Dec-1
+
+o	Add incremental 3D reconstruction output.
+
+o	Remove the reference to a non-existent web page in
+	unsupported::fornow().
+
+o	Allow device-specific bayer patterns to be overridden by the --bayer
+	option.
+
+o	Add an option for explicitly setting the camera view angle.  Make the 
+	default view angle 43.7 degrees.
+
+o	Implement optimizations that reduce the memory footprint when 3D
+	options are used.
+
+o	Modify the 3D cost reduction algorithm.  The new algorithm seems to
+	offer better results than the old in cases tested thus far, and does
+	not require that spatial extension be enabled.
+
+o	Add support for the Canon 300D with a 50mm f/1.4 lens (specifying view
+	angle), as well as experimental support for the 50mm f/1.4 lens at 1.4
+	(specifying a linear PSF).  Also add support for 50mm f/1.8 and 85mm
+	f/1.8 lenses, specifying view angles as specified in the chart at
+	http://www.acapixus.dk/photography/angle_of_view.htm
+
+o	Don't output final data when --psf-match is specified.  Doing so
+	would be useless anyway, and apparently causes a segfault.
+
+o	For cases where --psf-match is specified, modify the exposure settings
+	for the final input image (i.e., reference image) so that default
+	exposure is used, and modify the bayer pattern settings so that no
+	bayer pattern is used.  (The first of these modifications requires
+	changes in the way that the array of input exposures is stored.)
+
+o	Optionally (when OPTIMIZATIONS == 1) use the output of the default
+	rendering chain directly as the Irani-Peleg initial approximation,
+	instead of copying it.
+
+o	Add support for PSF convolution and scalar multiplication.
+
+o	Move all PSF parsing logic to a new file: d2/render/psf/psf_parse.h
+
+o	Modify help argument processing so that several help arguments can be
+	specified at a time.  Change the usage text to reflect this.
+
+o	Fix concatenated help output; outputs from all help options are now
+	represented.  (3D help had been omitted in 0.7.2.)
+
+o	Add a check to ensure that at most one --q* option is specified.
+	The issue of multiple --q* options being specified was raised on the
+	ALE mailing list by Viktors Rotanovs.  As there is currently no
+	support for this, generating an error message is appropriate.
+
+
+V	0.7.2 2004-Oct-26
+
+o	Add cost-minimizing code to reconstruct 3D scenes from 2D inputs.
+	(This code is currently very experimental.)
+
+o	Add rudimentary device support for raw, linear files from the Canon
+	EOS 300D (Digital Rebel) SLR.  CRW files may not be directly usable
+	under all configurations; in cases where they are not, Dave Coffin's
+	dcraw program, with arguments -d -4, will produce a raw, linear PPM
+	file.  See http://www.cybercom.net/~dcoffin/dcraw/
+
+o	Add a new option --gs-mo to establish a minimum overlap area for
+	global searches.  This may allow more of Derrick Brashear's historical
+	USGS contour map image sets to align successfully.  (from
+	0.7.1-patch2)
+
+o	Allow the scale factor to be explicitly set to one. (from
+	0.7.1-patch2)
+
+o	Print version information to stdout instead of stderr. (from
+	0.7.1-patch2)
+
+o	Add a rudimentary test suite. (from 0.7.1-patch2)
+
+o	Add support for --perturb-{upper,lower}=x%, where the value x% is
+	specified as a percentage of the smallest image dimension.  Use of
+	percentages to specify bounds was suggested by Jeff Epler. (from 
+	0.7.1-patch1)
+
+o	In render::is_excluded(), add the offset before checking exclusion
+	regions. (from 0.7.1-patch1)
+
+o	Add code to shrink the accumulated image in d2/render/incremental.h,
+	so that superfluously large undefined areas are never present.  This
+	may improve operation of '--gs inner' in some cases. (from
+	0.7.1-patch1)
+
+o	In d2::align::_align(), rescale default_initial_alignment in parallel
+	with the current transformation, so that it can be used again, if
+	necessary. (from 0.7.1-patch1)
+
+o	Add experimental options --perturb-source and --perturb-output, which
+	allow some refinement of the manner in which perturbation occurs.
+	(from 0.7.1-patch1)
+
+
+V	0.7.1 2004-Aug-27
+
+o	Fix --visp segfault when not using last: filters.
+
+o	Add help mode --hA to display all help pages.
+
+o	Add circular point-spread function option "circle=".
+
+o	Add support for the ov7620 sensor (raw, linear modes only).  (Updated
+	from 0.7.0-patch1 to specify a linear PSF.)
+
+o	Add global search option --gs to fix an alignment problem reported by
+	Bert Douglas.  (Also included in 0.7.0-patch1.)
+
+o	Change transformation::eu_{get,set,modify}() so that externally
+	visible values are interpreted in the context of transformations
+	between scaled images, while internal values represent transformations
+	between unscaled images.  (Bugfix for 0.7.0.  Also included in
+	0.7.0-patch1.)
+
+o	d2/tfile.h: Ensure that eu[] parameters are properly scaled when read
+	and written.  (Bugfix for 0.7.0. Also included in 0.7.0-patch1.)
+
+o	Fix order-of-operations bug in d2::image::scale_by_half().  (Bugfix
+	for 0.7.0 and earlier versions.  Also included in 0.7.0-patch1.)
+
+o	Scale alignment weights for reduced level-of-detail in d2::align().
+	(Also included in 0.7.0-patch1.)
+
+o	For reduced level-of-detail alignment reference images, filter
+	using alignment weights.  (Also included in 0.7.0-patch1.)
+
+o	Add speed optimizations for filtering in the Euclidean case, but
+	leave these disabled, since they are not safe.  (Also included
+	in 0.7.0-patch1.)
+
+
+V	0.7.0 2004-Aug-06
+
+o	Add support for algorithmic alignment weights.  This requires 
+	POSIX fork() and execlp(), so add a Makefile variable for POSIX.
+
+o	Add support for frequency-based alignment weights.  Angelo Pesce
+	had initially suggested the related (or more general) idea of
+	edge-based alignment.  Frequencies were chosen because of their
+	conceptual simplicity.  This option requires that FFTW be linked.
+
+o	Add support for specifying per-pixel and per-channel alignment weights
+	by providing an additional weight-map image, as suggested by Bert
+	Douglas.
+
+o	Remove support for USM.
+
+o	Add multiple default settings: q0, q1, q2, qn, qr.
+
+o	Partition help into sections, and add a section for transformation
+	data file help.
+
+o	Add a device type for the XVP610 camera in 640x480 mode.
+
+o	Modify the divisor in d2/render/ipc.h to ensure convergence when
+	using multiple varieties.
+
+o	Add experimental handling for Bayer patterns.
+
+o	Add experimental video stabilization options.
+
+o	Add options to control output range.  By default, use the range of the
+	original frame.
+
+o	For incremental rendering, add general filtering options.  Drizzling
+	options are no longer supported as such, but the help output offers
+	examples of how to emulate old drizzling/merging techniques (roughly).
+
+o	Add options --fail-default and --fail-optimal to select the desired
+	failure mode.  --fail-default uses the default alignment in the case
+	of failure.
+	
+o	Add option --ex, to support exclusion volumes.  Region exclusion was
+	first suggested to the author by Dewayne VanHoozer as a means of
+	solving the 'closed eye problem' in group photography.
+
+o	Add a barrel distortion adjustment multiplier and rate options.
+
+o	In d2/transformation.h, add parameters for barrel distortion correction.
+	In d2/tfile.h, add new barrel distortion command 'B'.  The approach
+	taken is based on that of Helmut Dersch's PanoTools.  (i.e., a
+	polynomial in radial distance is used.)
+
+o	Increment the latest supported transformation file syntax to version
+	3.  This version supports transformation of the original frame, as
+	well as other new features described above.
+
+o	Move d2/gpt.h to d2/transformation.h.
+
+o	In d2::align, add support for original frame transformations.
+
+o	In d2::align::diff() and d2::align::set_exposure_ratio(), treat cases
+	with and without extension identically.
+
+o	Report unrecognized transformation file commands as errors instead of
+	warnings.
+
+o	In the transformation data file handler, report incompatible
+	transformation types as an error instead of as a warning.
+
+
+V	0.6.0 2004-Feb-10
+
+o	Add a generalized, but rudimentary, implementation of Steve Mann's
+	notion of 'certainty'.  For more details, see
+	http://wearcam.org/comparametrics.pdf
+
+o	Make stdin filter height and width independent of each other.
+
+o	In the Irani-Peleg renderer, skip frames that fail to reach the match
+	threshold.
+
+o	Convert some operations on pixels and points into vector syntax 
+	through C++ operator overloading.
+
+o	Add command-line options to select plain or raw PNM/PPM formats.  Remove
+	makefile variable PLAIN.
+
+o	Add command-line options to select 8/16 bits per channel.  Remove
+	makefile variable BITS.
+
+o	Revise the device configuration xvp610_320x240 to use a new
+	filter, reflecting driver updates (see the relevant web page
+	http://auricle.dyndns.org/xvp610/ ) and support for non-linear
+	colorspace point-spread functions.
+
+o	In the Irani-Peleg renderer, use a discrete Fourier transform to
+	ensure that each (point-spread function, backprojection kernel) pair
+	satisfies condition (9) from theorem 4.1 in the source paper.
+
+o	Add a point-spread function rasterizer.  
+
+o	Extend the --replace option to support drizzling.
+
+o	Add support for exposure registration (i.e., matching of exposure
+	between different frames).
+
+o	Change -Os to -O2 in the Makefile, since -Os no longer achieves speedup
+	in the most critical codepaths.
+
+o	Add command-line support for summation of point-spread functions.
+
+o	Add a polymorphic point-spread function type psf and convert all
+	external interfaces of ipc.h and usm.h (formerly hf-enhance.h) to use
+	this type.  
+
+o	Fix memory leak in d2/render/combine.h:get_image().  (This fix is also
+	included in a patch for 0.5.1.)
+
+o	Modify the USM renderer to write output when incremental output is
+	enabled.
+
+o	In the USM renderer, now only defined pixel values contribute to the
+	mask.  Also, undefined values are no longer masked.
+
+o	Update e-mail address information.
+
+o	Modify the Irani-Peleg calibration script into a general point-spread
+	function calibration script, using a new built-in point-spread function
+	evaluation module to rate candidates.
+
+o	Irani-Peleg and USM (High-frequency enhancement) renderers now
+	use the same point-spread function configurations.  New options --ips,
+	--usm, --lpsf, --nlpsf, and --device subsume and extend the
+	functionality provided by options --ip, --ipc, and --hf-enhance.
+
+o	Add support for convolutions in non-linear colorspace.  This feature
+	is enabled and configured by the command-line option --nlpsf.  (See
+	also the item above.)
+
+o	Linearize channel values within internal data structures so that most 
+	ALE operations are performed on linear data.  Steve Mann discusses the
+	use of linear representations in image processing, e.g. in his paper
+	http://wearcam.org/comparametrics.pdf .  We assume a simple power-law
+	response by default.
+
+o	Modify the image class to use a floating-point data type for 
+	storing pixels.
+
+o	Modify the README to remove information covered in the User Manual.
+
+o	Revise identifiers and comments in d2/render/ipc.h to better reflect
+	the terminology used in the source paper by Irani and Peleg.
+
+o	Consoldiate code for computing the position and dimensions of a pixel in a
+	new coordinate system, and use this new abstraction to reduce the code
+	size of d2/render/ipc.h and d2/render/drizzle.h (Irani-Peleg and
+	drizzling code, respectively).
+
+o	Change several instances of 'double', 'float', and 'my_real' to
+	specialized floating-point types 'ale_real', 'ale_pos', 'ale_sreal',
+	and 'ale_accum'.
+
+o	Fix offset calculation in d2/render/ipc.h.  This is necessary for
+	Irani-Peleg rendering of image mosaics extending upwards or to the
+	left of the original frame.  (This fix is also included in a patch for
+	0.5.1.)
+
+o	Move classes treating snapshots as two-dimensional data to directory
+	'd2' and create an associated C++ namespace.  We can't use '2d' to
+	label the namespace, because the C++ grammar won't allow it.
+
+
+V	0.5.1 2003-Nov-19
+
+o	Several of the changes below are based on a suggestion by Bert
+	Douglas regarding support for 16-bit-per-channel color.  See the README
+	for more information about relevant compilation options.
+
+o	Add information to the README regarding new compilation options.
+
+o	Modify the makefile to accept a variable BITS, and differentiate between
+	values BITS=8 and BITS=16.  The latter option causes the macro BITS_16
+	to be defined during compilation.
+	
+o	Modify image_rw.h to handle 16-bit data when BITS_16 is defined.  Also,
+	differentiate between 8-bit and 16-bit ImageMagick builds by checking
+	MaxRGB.
+
+o	In ppm.h, add carriage returns to the set of recognized whitespace
+	characters.
+
+o	Modify ppm.h to read 16-bit binary PPM files (added to the PPM format
+	spec in April 2000).  
+
+o	Modify ppm.h to read plain (ASCII) as well as raw (binary) PPM files.  
+
+o	Add a Makefile option for writing plain (ASCII) PPM files instead of
+	raw (binary).  This option causes the macro PPM_PLAIN to be defined
+	during compilation.
+	
+o	Modify ppm.h to write plain (ASCII) PPM files when PPM_PLAIN is defined.
+
+o	Modify ppm.h to output 16-bit PPM files when BITS_16 is defined.
+
+o	Modify ppm.h to scale input intensity values based on the internal
+	representation depth (8 or 16 bits per channel).
+
+o	Add a file 'channel.h' to describe the color channel data type and
+	valid range, both being dependent on whether BITS_16 is defined.  Use
+	these generic values, where appropriate, throughout the ALE codebase.
+
+
+V	0.5.0 2003-Nov-02
+
+o	Remove certain cloning operations from align.h, but since cursory tests
+	indicate that scaling with --scale is much more expensive than cloning,
+	allow cloning to occur when scaling occurs.
+
+o	Add more comment documentation to header files.
+
+o	Emit a more informative error message when the PPM file handler
+	encounters a file that is not a well-formed PPM binary file.
+
+o	Move rendering implementations to subdirectory 'render/'.
+
+o	Modify semantics of alignment following by applying to file-loaded
+	initial transformations a delta transformation D = AB^-1, where B is
+	the previous frame's (unmodified) initial transformation, A is the
+	previous frame's final transformation, and ^-1 is the inverse operator.
+	Using --follow with --trans-load can now improve alignment success when
+	working with panoramic image mosaics.
+
+o	We're not using simulated annealing, so remove comments that claim
+	otherwise.
+
+o	Remove certain unsafe assumptions from ipc/* (now render/ipc/*); this
+	change includes a modification to ipc.h (now render/ipc.h).  Limits of
+	the rectangle used as an argument to the ::response() function
+	are now explicitly given rather than implied.
+
+o	Change documentation for --replace.
+
+
+V	0.4.8 2003-Aug-01
+
+o	Modify Irani-Peleg renderer to produce incremental output.
+
+o	Modify Monte Carlo alignment so that the same set of accumulated image
+	pixels is examined when comparing two transformations.
+
+o	Add an option for additional upper-bound constraint of rotational
+	perturbation.  Jeff Epler had noted that the
+	perturb-upper/perturb-lower options alone may not be suited to working
+	with sets of higher-resolution images.  
+
+o	Resolve a bug introduced in version 0.1.1 which had limited rotational
+	perturbation to 2 degrees.
+
+o	Add an option to adjust the maximum level of detail used.  The default
+	maximum is 2/perturb, which matches the default for previous versions
+	of ALE.
+
+o	Modify names of temporary files used in the calibration script.
+
+
+V	0.4.7 2003-Jul-27
+
+o	Add a replacement option suggested by Jeff Treece.  This option can
+	be used to facilitate video stabilization.
+
+o	Irani-Peleg: add support for configurable modules, including 
+	a module that reads its configuration data from standard input
+	and a module calibrated for an IBM (Xirlink) XVP610 in 320x240
+	mode.  A rudimentary script for calibrating devices with unknown
+	projection functions has been included as ipc/ale-calibrate.
+
+o	Irani-Peleg: don't truncate correction values in backprojection.
+
+o	Irani-Peleg: don't multiply the weight function by a scale correction
+	factor in backprojection.
+
+o	Rename render::operator()() to render::sync().  Update subclasses
+	accordingly.
+
+
+V	0.4.6 2003-Jul-01
+
+o	Allow --ip and --hf-enhance to be used together.  [Modify
+	ip::operator() and hf_filter::operator() so that multiple
+	post-processing filters can be used.]
+
+o	Initialize the drizzled image to be uniformly black.  This fixes
+	a bug introduced in 0.4.2.
+
+o	Allocate the correct size image for drizzling.  This fixes a bug
+	introduced in 0.4.5.
+
+
+V	0.4.5 2003-Jun-23
+
+o	Ensure correct transformation scaling and difference calculation after
+	alignment is complete, even if alignment terminates with a reduced
+	level of detail (i.e. perturb-lower > 2).
+
+o	Separate the scale() function into two cases: scale() is reserved for
+	scale factors greater than or equal to one, as in user-specified
+	scaling; and scale_by_half() is used for the scale factor 0.5, needed
+	to provide multiple levels of detail in alignment.  Modify the
+	scale_by_half() case to reflect source pixel values more fairly.  (This
+	change affects alignment behavior at reduced levels of detail.)
+
+o	Reduce whitespace in usage() message.
+
+o	Modify align::diff() to use correctly scaled image offset values.
+	(Bugfix for alignment with --extend.)
+
+o	Modify align.h so that the image definition array is correctly scaled
+	for all levels of detail.  (Bugfix for alignment with --extend.)
+
+o	Modify image.h to correctly handle image offset values.  (Bugfix
+	for --extend operation.)
+
+o	Remove call to stat() in image_rw.h.  This improves OS independence,
+	and apparently also allows URL-specification of images when compiled
+	with ImageMagick support.
+
+o	Modify image file handler interface so that input files are not scaled.
+	Perform scaling, when necessary, outside of the file handler.  Since
+	unscaled data is needed by the drizzling and Irani-Peleg code, this
+	fixes bugs in those modules.  
+
+
+V	0.4.4 2003-Jun-06
+
+o	Modify the Monte Carlo pixel selection algorithm so that the expected
+	number of sampled pixels more closely matches the specified number in
+	typical cases.
+
+o	Specify the binary mode flag to fopen() calls in the PPM file handler.
+	This change resolves a bug discovered by Benjamin Hill.
+
+
+V	0.4.3 2003-May-30
+
+o	Add support for Monte Carlo alignment of images, in which only a
+	random subset of pixels is sampled.
+
+o	Add an option to disable incremental image output.
+
+
+V	0.4.2 2003-May-23
+
+o	Implement an image reconstruction option based on the work of Irani and
+	Peleg.
+
+o	Clean up source; move rendering and alignment functions into separate
+	files.
+
+o	Change valid drizzling diameter interval to (0,1].
+
+o	Modify PPM file reader to correctly handle comments in PPM files; this
+	resolves a bug pointed out by Benjamin Hill.
+
+o	Add missing typecast to resolve compile warning under GCC 3.2.
+
+o	Make changes to gpt.h that may reduce the Euclidean alignment time.
+
+o	Move ale.c to ale.cc to follow one of the many C++ naming conventions.
+
+
+V	0.4.1 2003-Apr-28
+
+o	Change language to C++.
+
+o	Code cleanup in ale.c, image.h, and gpt.h.
+
+o	Separate into a number of subsections the option descriptions in the
+	README 
+
+o	Add URL information to README
+
+o	Add an experimental drizzling implementation.  Research on drizzling
+	by Richard Hook and Andrew Fruchter was brought to the attention of 
+	the author by Dan Kaminsky.
+
+o	Add an option to use the previous frame's final transformation as the
+	default alignment.
+
+o	Change pixel weight data type so that more than 255 images can
+	be merged.
+
+o	Add support for increased spatial extents.  Research on increased
+	spatial extents by Steve Mann was brought to the attention of the
+	author by Dan Egnor.
+
+o	Modify the transformation algorithm to use transformations from the
+	domain of the input image to the range of the target image.  This
+	change is reflected in transformation files.  Maintain support for
+	old transformation file versions, however.
+
+o	Add version information to transformation files and update the version
+	from 0 to 2.
+
+
+V	0.4.0p1 2003-Apr-04
+
+o	Merge a bugfix from Debian ALE package version 0.4.0-1.  Without this
+	fix, an assertion failure can occur when ImageMagick support is
+	enabled.  Original fix implemented by Nick Rusnov.  
+
+
+V	0.4.0 2003-Mar-30
+
+o	Add support for general scaling parameters (i.e. all scale 
+	factors >= 1.0).  --scale2, --scale4, and --scale8 are now deprecated, 
+	and replaced with a more general --scale=x argument.
+
+o	Support enhancement of high frequencies even when the scale factor is 
+	1.0.
+
+o	Modify the high-frequency filter algorithm to support filtering near
+	the border of an image.
+
+o	Modify the high-frequency filter function so that the response is now
+	(4/n)^2 times what it used to be, where n is the scale factor.  
+
+
+V	0.3.2 2003-Mar-26
+
+o	Don't filter high frequencies if we're not enhancing them.  This 
+	improves efficiency, but should not affect output.
+
+
+
+V	0.3.1 2003-Mar-25
+
+o	Output average match statistic.
+
+o	Update informational output to transformation files to include original 
+	frame.
+
+o	Add support for post-enhancement of high-frequency details.
+
+
+V	0.3.0 2003-Jan-17
+
+o	Add support for loading and saving transformation data.
+
+o	Add an option to set the upper bound on correction steps.
+
+o	Modify Makefile to compile with size optimization, since this 
+	appears to improve speed characteristics in some cases.
+
+/alignment
+o	Move transformation data structure and related functions to 
+	a separate header file.
+
+
+V	0.2.0 2003-Jan-01
+
+o	Add support for general projective transformations, and change/add
+	options as follows:
+
+		'--translation'	used to be	'--no-rotate'
+		'--euclidean'	used to be 	'--rotate'
+		'--projective'	is a new option
+
+
+V	0.1.2 2002-Dec-13
+
+o	Add optional support for .jpg, .png, .tiff, and other file formats
+	through ImageMagick.  Translation using ImageMagick was suggested by
+	Nick Rusnov.
+
+/image-files
+o	Don't segfault if a file can't be opened.
+
+
+V	0.1.1 2002-Dec-09
+
+o	Use reduced levels of detail in coarser alignment steps to increase
+	speed.
+
+o	Change perturbation step lower-bound check from less-than ('<') to 
+	less-than-or-equal-to ('<=').  Change default lower bound
+	to .125 from .1 (the behavior is the same, but the value
+	makes more sense).
+
+o	Change perturbation initial value to 32 pixels from
+	16 pixels, since coarse alignment is now less expensive.
+
+o	Modify scale function so that the borders aren't 
+	corrupted (too badly).
+
+
+V	0.1.0 2002-Nov-26
+
+o	Add support for correction of rotation about the lens axis.
+
+o	Add an optional match criterion for merging.
+
+o	Add an option to adjust minimum step-size.
+
+o	Add flags to specify which channels to use for alignment.  Use
+	a summation of all channels by default.
+
+o	Add an option to modify the error metric exponent, and change
+	the default value from 1 to 2. 
+
+o	Display information about how well a new image matches
+	the accumulated image.
+
+o	Add a rule for ale.exe to the Makefile.  
+
+
+V	0.0.0 2002-Oct-11
+
+/initial-release
+o	Initial release.

+
+0.8.5 (Prerelease)
+
+
+Documentation
+
+
  • Migrate documentation to a modified DocBook format.
+
+
  • Revise README for autotools build and installation.
+
+
  • Add file 'TODO', containing a tentative list of future versions
+         and features.
+
+
  • Add AUTHORS file, in accordance with the autotools packaging
+	standards.
+
+
  • Revise Changelog name to autotools-recognized ChangeLog
+
+
  •  Add NEWS file containing summary announcement text, including mailing
+	  list and Freshmeat announcements for versions through 0.8.4.  This
+	  file is required by autotools when not running in --foreign mode.
+

+
+
+
+
+Configuration
+
+
  • Add autotools-based configuration, build, and installation facilities,
+	replacing the earlier Makefile-based configuration and build process.
+

+
+
+
+Command-line interface
+
+
  • Modify command-line interface to accept certain scope operators, and
+	to increase uniformity of syntax.
+

+
+
+
+Image constraints
+
+
  • Add options --f{ex,crop} for frame-coordinate exclusion regions.
+

+
+
+
+3D Rendering
+
+
  • In d3::scene, always use filler spaces when --pc all is specified.
+

+
+
+
+Source code organization
+
+
  • Move input interface details, including option handling, messages,
+	and help information, to the ui/ subdirectory.
+

+
+
+
+
+
+
+0.8.4 2006-May-14
+
+
+
+
+
+Packaging
+
+
  • Fix build error noted by Gregory Maxwell and re-tag version.
+

+
+
+
+Documentation
+
  • Add dates to the Changelog, using dates in comments in the download
+	page on the website for versions prior to 0.8.0, and using dates from
+	the darcs repository for versions 0.8.0 and later.
+

+
+
+
+Command-line interface
+
+
  • Add fine-grain UI updates for 3D operations when using ui=tty.  Reduce
+	tty UI status update frequency to at most once per second.
+

+
+
+
+
+3D Rendering
+
  • Add support for synthetic focus via the --focus option, including
+	focus with horizontal and vertical tilt.  Adding simulated focus
+	effects, including tilted and swung focal planes, was suggested by
+	Gregory Maxwell.
+
  • Add support for filtering 3D output with --3d-filter.  This
+	is now the default behavior.  Add an option --3d-chain for selecting
+	the filter chain used for 3D output.  (See --hl and --hq for details.)
+
  • Interpolate to generate smooth 3D depth output.
+
+

+
+
+
+3D Models
+
  • Modify --3dpx to affect scene geometry rather than rendered
+	pixels.  In certain cases, this change should allow removal of objects
+	close to the camera, hence revealing objects further away.
+
  • Add decimation options --di-upper, --di-lower, and --do-try for
+	reducing the complexity of 3D scene geometry, hence reducing the
+	number of operations required for occupancy updating.
+
  • Fix dimension comparison bug in d3::space::traverse::get_next_split().
+
  • Implement an experimental approach to 3D subspace candidate selection;
+	this seems to perform poorly in most cases due to parallax effects.
+	See the source code for details.  (Option --subspace-traverse)
+
  • Add adaptive weight decomposition to 3D occupancy algorithms.
+
  • Move low-level code concerning scale and level-of-detail from
+	d3::scene to d3::pt.
+
  • Move code concerning the nature of space from d3::scene to 
+	d3::space.
+
  • Remove older 3D rendering code. 
+

+
+
+
+
+Scripts
+
  • Add a script 'transform' for applying an inverse projective
+	transformation.  Recalculation of transformations was suggested by Rob
+	Stewart (ALE mailing list message, 2005-Dec-28).
+

+
+
+
+Undocumented options
+
  • Add to the Makefile a HASH_MAP option that can be used to assign the
+	3D spatial info structure a hash map type instead of the standard STL
+	map type.  As this is likely to break things, it is currently
+	undocumented.  HASH_MAP=GNU seems to compile with g++ 4.0.x but
+	has not otherwise been tested.
+

+
+
+
+
+
+
+
+0.8.3 2005-Dec-23
+
+
+
+Rendering
+
+
  • Add an option --def-nn to allow definition of pixels in output images
+	to take values from neighboring pixels within a certain radius, in
+	cases where they would not otherwise be defined.
+

+
+
+
+
+3D Models
+
+
+Stereoscopy
+
+
  • Add option --pc to specify which pairwise comparisons should be
+	performed.
+
  • Add option --pa to set the number of point candidates accepted
+	for each pair of cameras (pairwise ambiguity).  The default
+	of 3 preserves existing default behavior.
+
  • Add option --tcem for scoring point candidates by third-camera
+	views.  The default of 0 preserves existing default behavior.
+

+
+
+
+Geometry
+
+
  • Add option --3dpx to specify 3D regions to exclude during final
+	rendering, using a single depth for each pixel in each frame of
+	rendered output.  (Evaluates at the depth used in depth-rendering.)
+
+
  • Add --et option to specify encounter thresholds.
+
+
  • Modify representation of 3D subspaces so that refined subspaces
+	are roughly cubical, and to allow refinements at multiple
+	resolutions.
+
+
  • Clean up d3::scene to remove triangle-mesh code.
+

+
+
+
+Occupancy
+
+
  • Fix bugs in 3D color and occupancy updating caused by bounding
+	box miscalculation.
+
+
  • Add option --oui for determining occupancy update iterations.
+	The new default is 10, halving the previous default of 20.
+
+

+
+
+
+
+
+
+0.8.2 2005-Nov-22
+
+
+
+Image files
+
+
  • Add magical file 'dump:' for listing color values numerically
+	to stderr.
+

+
+
+
+
+3D Models
+
+
  • Transition from a subdivisible triangle model to a subdivisible	
+	space model, using a rudimentary implementation of Hans Moravec's 
+	notion of occupancy.
+
+
  • Add support for view and depth output from arbitrary cameras.
+
+
  • Add clipping plane options for 3D modeling.
+

+
+
+
+
+Control points
+
+
  • Fix various bugs in control-point alignment reported by Gregory
+	Maxwell.
+

+
+
+
+
+
+
+0.8.1 2005-May-6
+
+
+
+Build
+
+
  • Fix enumerator compile bugs noted by Gregory Maxwell and Tom Holroyd
+	to cause compilation failure under GCC 3.4.
+

+
+
+
+
+Defaults
+
+
  • Modify --q1 to use median-value incremental rendering.
+

+
+
+
+
+Rendering
+
+
  • Add support for median-value incremental and Irani-Peleg rendering.
+	Using a statistic other than the mean was suggested by Scott Scriven
+	as a means of eliminating non-uniform artifacts.  Using the median
+	seems to improve performance on Scott Scriven's example sequences, as
+	well as on the scaled output of fine:sinc*lanc for sparse inputs.
+

+
+
+
+
+Exposure
+
  • Add a color adjustment option --exp-mult=.
+

+
+
+
+Control points
+
+
  • Add support for using control points in 2D and 3D alignment, as well
+	as in 3D model construction.  New options include '--gs points',
+	'--cpf-load=', '--cpp-upper=', '--cpp-lower=', '--va-upper=', and
+	'--st'.
+

+
+
+
+
+
+Transformation data files
+
+
  • Add average magnitude comments to transformation data file output.
+

+
+
+
+
+3D Models
+
  • For 3D scene reconstruction, use a new unified surface model in place
+	of the depth-based multi-model approach used in 0.8.0.  The new model
+	is adjusted on the basis of edge, angle, and color measures.
+

+
+
+
+Scripts
+
+
  • Move ale-psf-calibrate to a new scripts directory.
+

+
+
+
+
+
+
+0.8.0 2005-Jan-12
+
+
+
+
+Command-line interface
+
  • Add user interface options --ui=stream and --ui=tty.  The latter
+	includes more detailed status output when terminal width information
+	can be obtained (esp. when IOCTL=1 is set at compile time), and is the
+	new default.
+

+
+
+
+Exclusion regions
+
  • Add --crop argument, which excludes the spatial complement of a
+	specified area over a specified set of frames.  Gregory Maxwell notes
+	several advantages of internal over external crops, including
+	preserving knowledge of position in the uncropped frame, which among
+	other benefits allows natural handling of Bayer patterns.
+
  • Modify rx_parameters in d2/render.h to use the ale_pos data type
+	instead of int.  This should allow exclusion regions to be calculated
+	more accurately.
+
+

+
+
+
+Image files
+
  • Add support for PPM with extended attributes (EPPM).  Attributes
+	handled specially include black level, shutter speed, aperture, and
+	ISO (or gain).
+

+
+
+
+Exposure
+
  • Add a flag --exp-meta-only which causes tonal registration to be
+	performed only on the basis of exposure metadata (e.g., data encoded
+	as EPPM extended attributes).  This approach was suggested by Gregory
+	Maxwell.
+
  • Fix an index variable bug in d2::image_bayer_ale_real::trigger().
+
  • Modify d2::exposure one-sided certainty so that the 'one-sided'
+	condition only applies to bright (>50%) areas.  Applying it to dark
+	areas has no clear benefit, and an experiment by Gregory Maxwell
+	demonstrates that doing so can exacerbate noise.
+
+

+
+
+
+Alignment
+
  • Modify euclidean alignment so that perturb-upper and perturb-lower
+	apply to rotational arclength.
+
  • Modify d2::align to use unscaled input images when the scale factor
+	is larger than 1.0, or when a scaled_filter interpolant is being used.
+
  • Modify d2::align::set_exposure_ratio() so that alignment 
+	weights and certainty values are taken into consideration.  
+
  • Add a --cw option to weight alignment error by certainty values,
+	as suggested by Gregory Maxwell.  This allows the contributions of
+	pixels at maxval to be diminished, which can increase alignment
+	success in certain cases.
+

+
+
+
+Rendering
+
+
+Scale
+
+
  • Modify d2::image::scale() to allow scale factors in the interval 
+	(0, 1), and modify the command-line interface and help text to reflect
+	this change.  --scale= now accepts all finite positive values.
+
+

+
+
+
+Incremental
+
  • Replace functions d2::incremental::{increase,decrease}_extents()
+	with new functions that take exclusion regions into account.  The new
+	functions should also fix a boundary-calculation bug reported by
+	Gregory Maxwell.
+
+

+
+
+
+Irani-Peleg
+
  • Set image offsets in d2/render/combine.h.  This allows Irani-Peleg
+	rendering to work with --crop when the default rendering chain
+	includes more than one rendering invariant.
+
  • Perform Irani-Peleg updating separately by channel instead of
+	using vector operations.  This allows divide-by-zero and other
+	conditions to be localized to particular channels.
+
  • Modify the Irani-Peleg renderer to use estimate-based certainty.  This
+	seems to improve noise characteristics significantly.
+
  • Modify d2::render::ipc::_ip_frame_correct() so that exposure
+	re-estimation uses a ratio of weighted sums instead of a weighted
+	average of ratios.
+
  • Modify d2/render/ipc.h to handle exclusion regions more effectively.
+

+
+
+
+
+
+Transformation data files
+
  • Write the results of tonal registration as a comment in the 
+	transformation data file.
+

+
+
+
+3D Models
+
  • Add experimental cost calculation routines to d3/scene.h.
+

+
+
+
+Source code organization
+
  • Move certain user interface elements to the source subdirectory ui/.
+

+
+
+
+
+
+0.7.3 2004-Dec-1
+
+
+
+3D Models
+o	Add incremental 3D reconstruction output.
+
+
+
+Command-line interface
+o	Remove the reference to a non-existent web page in
+	unsupported::fornow().
+
+
+
+Rendering
+Should the --bayer option be moved to another section?
+o	Allow device-specific bayer patterns to be overridden by the --bayer
+	option.
+
+
+
+3D Models
+o	Add an option for explicitly setting the camera view angle.  Make the 
+	default view angle 43.7 degrees.
+
+
+o	Implement optimizations that reduce the memory footprint when 3D
+	options are used.
+
+o	Modify the 3D cost reduction algorithm.  The new algorithm seems to
+	offer better results than the old in cases tested thus far, and does
+	not require that spatial extension be enabled.
+
+o	Add support for the Canon 300D with a 50mm f/1.4 lens (specifying view
+	angle), as well as experimental support for the 50mm f/1.4 lens at 1.4
+	(specifying a linear PSF).  Also add support for 50mm f/1.8 and 85mm
+	f/1.8 lenses, specifying view angles as specified in the chart at
+	http://www.acapixus.dk/photography/angle_of_view.htm
+
+o	Don't output final data when --psf-match is specified.  Doing so
+	would be useless anyway, and apparently causes a segfault.
+
+o	For cases where --psf-match is specified, modify the exposure settings
+	for the final input image (i.e., reference image) so that default
+	exposure is used, and modify the bayer pattern settings so that no
+	bayer pattern is used.  (The first of these modifications requires
+	changes in the way that the array of input exposures is stored.)
+
+o	Optionally (when OPTIMIZATIONS == 1) use the output of the default
+	rendering chain directly as the Irani-Peleg initial approximation,
+	instead of copying it.
+
+o	Add support for PSF convolution and scalar multiplication.
+
+o	Move all PSF parsing logic to a new file: d2/render/psf/psf_parse.h
+
+o	Modify help argument processing so that several help arguments can be
+	specified at a time.  Change the usage text to reflect this.
+
+o	Fix concatenated help output; outputs from all help options are now
+	represented.  (3D help had been omitted in 0.7.2.)
+
+o	Add a check to ensure that at most one --q* option is specified.
+	The issue of multiple --q* options being specified was raised on the
+	ALE mailing list by Viktors Rotanovs.  As there is currently no
+	support for this, generating an error message is appropriate.

Patch to fix build failures under GCC 3.4 noted by Gregory Maxwell and Tom
+Holroyd

+
+
+
+
+
+
+This release adds a more informative TTY user interface, increases Euclidean
+alignment precision for large images, and reduces certainty-related noise
+amplification in the Irani-Peleg renderer.
+
+
+
+
  • Add a more informative TTY user interface
+
  • Increase Euclidean alignment precision for large images
+
  • Reduce certainty-related noise amplification in the Irani-Peleg renderer
+

+
+
+
+
+
+
+
+

  • Add new PSF options for convolution and scalar multiplication
+
  • Revise the 3D scene reconstruction algorithm
+

+
+
+
+ALE is an image-processing program used for tasks such as
+super-resolution, deblurring, noise reduction, and anti-aliasing. Its
+principle of operation is synthetic capture, combining multiple inputs
+representing the same scene.
+
+
+
+
+
+
+
+This release fixes exclusion region and alignment bugs, adds device support for
+the Canon 300D SLR, and incorporates an experimental framework for
+reconstruction of 3D scenes.
+
+
+
+
  • Incorporate changes from 0.7.1 patches
+
  • Add a device configuration for the Canon EOS 300D (Digital Rebel)
+
  • Incorporate an approach to 3D reconstruction.  (Does not work yet.)
+

+
+
+
+
+
+
+
+
  • Adds an option for establishing a minimum overlap area for global searches
+
  • Adds a rudimentary test suite.
+

+
+
+
+
+
+
+
+
  • Allows each perturbation bound to be specified as a percentage of the
+  smallest image dimension (useful for large images?).
+
  • Fixes bugs in exclusion region handlers.
+
  • Fixes bugs in alignment failure handlers.
+
  • Avoids superfluously large undefined regions.
+
  • Adds experimental options for refining perturbation.
+

+
+
+
+
+
+
+
+This release fixes alignment bugs, adds a global search option, and adds
+support for the OmniView OV7620 sensor.
+
+
+
+
  • Add linear PSF for OV7620
+
  • Add option to concatenate help pages
+
  • Fix VISP segfault
+
  • Incorporate changes from 0.7.0-patch1
+

+
+
+
+The default PSF for the OV7620 can be a bit noisy.  As an alternative,
+box=1.3+box=1.8 also works well in some cases, and is less noisy.
+
+
+
+
+
+
+
+
  • Fixes alignment bugs.
+
  • Adds a global search option.
+
  • Adds support for ov7620 in raw, linear mode.
+

+
+
+
+The ov7620 device option expects that the 7620 be in raw, linear mode, and that
+clamping be turned on.  These features may not be accessible using standard
+drivers.
+
+
+
+
+
+
+
+This release updates the renderer to support a variety of filters, including
+sinc and Lanczos, and adds new options for excluding image regions and
+processing video frames.
+
+
+
+
+
+
+
+Merging and drizzling renderers now operate in linear colorspace, and the
+Irani-Peleg renderer has been extended to handle convolutions in both linear
+colorspace (e.g. lens blur) and non-linear colorspace (e.g. some types of
+in-camera sharpening). New options in this release include certainty weighting
+and exposure registration. 
+
+
+
+
+
+
+
+Changes in this release include optional support for 16-bit color channels and
+built-in support for all PPM file types. Also, a user manual and an updated
+technical description are now available. 
+
+
+
+[This release was, and remains (as of Sep 2006), the most advanced version
+storing pixels as integer values (rather than as floating-point values).  As
+integer values may be more suitable for certain applications, integer-valued
+functions may be re-introduced, possibly as library code, in the future.
+19-Sep-2006]
+
+
+
+ALE is a program that can render high-fidelity images of real
+scenes by aligning and combining many similar images from a camera or
+scanner. The correct similarity between images is roughly that achieved by
+a somewhat unsteady hand holding a camera. 
+
+
+
+
+
+
+
+Alignment following has been modified to support multiple-pass alignment of
+panoramic image mosaics. Other changes in this release include code cleanup and
+documentation updates.
+
+
+
+
+
+
+The Monte Carlo alignment algorithm has been modified, and may now offer better
+alignment for small sample sizes. Also, the Irani-Peleg renderer now writes
+output after each iteration when incremental output is enabled. Other changes
+include a bugfix in Euclidean alignment, a new option for configuring the level
+of detail, and a new independent constraint for rotational perturbation.
+
+
+
+
+
+
+
+Support for device-specific projection functions and various bugfixes have been
+added to the Irani-Peleg renderer. Also, a new option has been added that may
+be useful for video stabilization applications.
+
+
+
+
+
+
+This release fixes bugs in drizzling and post-processing. The following
+combinations should now work as expected: drizzling in combination with scaling
+and Irani-Peleg image reconstruction in combination with high-frequency
+enhancement.
+
+
+
+
+
+
+
+This release resolves a number of minor alignment bugs. 
+
+
+
+
+
+
+
+The PPM file handler has been updated to open files in binary mode, resolving a
+serious bug under Windows. Also, the percentage of pixels used in Monte Carlo
+alignment now more closely matches user specifications in typical cases.
+
+
+
+
+
+
+
+A Monte Carlo alignment option has been added, which may reduce alignment time.
+An option to disable incremental file output has also been added.  
+
+
+
+
+
+
+
+An iterative image reconstruction renderer has been added, and the PPM file
+handler has been updated to correctly handle PPM header comments.
+
+
+
+
+
+
+
+Increased spatial extents, drizzling, and new alignment options have been added
+in this release.
+
+
+
+
+
+
+
+A bugfix from the Debian ALE package version 0.4.0-1 has been merged. Without
+this fix, an assertion failure can occur when ImageMagick support is enabled.
+
+
+
  • The original Debian fix was implemented by Debian package maintainer Nick
+  Rusnov.
+

+
+
+
+
+
+
+
+A general scaling option has been added, and the high-frequency enhancement
+filter now works near image boundaries.
+
+
+
+
+
+
+
+A match summary was added to the program's output, comments in transformation
+file output were made more helpful, and an experimental high-frequency
+enhancement option was added.
+
+
+
+
+
+
+(This release appears to have been superseded by 0.3.2.)
+
+
+
+
+
+
+
+New options in this release facilitate writing final alignment transformations
+to a file, reading initial alignment transformations from a file, and setting
+an upper boundary on the correction step size used in alignment. 
+
+
+
+
+
+
+
+General projective transformations can now be used in image alignment.
+
+
+
+
+
+
+
+A new file handler has been added to read and write JPEG, PNG, and other image
+formats using the ImageMagick C API. The default PPM-only file handler now
+deals with certain file errors more gracefully.
+
+
+
  • Translation of file formats using ImageMagick was suggested by Nick Rusnov.
+

+
+
+
+
+
+
+In this version, a scaling bug that caused corruption of boundary pixels has
+been fixed. Also, the alignment algorithm has been modified to use reduced
+detail for coarse alignment steps.
+
+
+
+
+
+
+
+The image alignment algorithm has been updated.
+
+
+
+
+
+
+
Initial release

+
+
+ALE aligns and merges several similar images from a digitizing device (such as
+a digital camera or scanner) into a single image. This may have the effect of
+producing a relatively alias-free image (sometimes called "anti-aliasing").

  • 
+

+
+
+
+Build prerequisites
+
+GCC C++ compiler
+
+
 GCC version 3.2.3 with C++ support is known to build ALE successfully.  Older
+versions of GCC may fail to compile some versions of ALE.

+
+
+
+Prerequisites for building on Windows
+
+
 Successfully running the configuration script on Windows (e.g., for native
+builds) may require installation of Cygwin.  For more information on Cygwin,
+see:

+
+
  • 
+

+
+
Alternatively, this package can be cross-compiled for Windows on a non-Windows
+architecture, provided that the appropriate cross-compilers and libraries are
+available.

+
+
+
+
+
+Extraction
+
+
Download the source archive file from the URL indicated in the section
+'URLs', and invoke:

+
+tar xzf 
+cd 
+
+
+
Invoking 'ls configure' afterward should reveal an executable script
+'configure'.  This script is used to determine the capabilities of the system
+that will run the software.

+
+
+
+Running configure
+
+
This package uses a configuration script, 'configure', generated by the GNU
+project build tools ("autotools").  For most cases, it should be sufficient to
+invoke:

+
+./configure
+make
+make install
+
+
+
In cases where the defaults are not adequate, configuration options can be
+passed to the configuration script.

+
+
+Configuration options
+
+
Configuration options can be passed to the 'configure' script prior to build
+and installation, as:

+
+./configure --config-option1 --config-option2 ...
+make
+make install
+
+
+
Options specific to this package are described in the following subsections.
+General configuration options are described in the file 'INSTALL' included in
+the source package.

+
+ImageMagick Support
+
+
Enabling ImageMagick support allows ALE to make use of the file-handling
+capabilities of ImageMagick (  ).  This
+includes reading and writing a variety of file formats, including, among many
+others, PNG and JPEG (two formats commonly used in web publishing) as well as
+common interchange formats such as PPM and TIFF.  ImageMagick 6.0.6 is known to
+work with this version of ALE; certain older versions of ImageMagick may cause
+compile, link, or runtime errors.  By default, support is automatically
+detected.

+
+--with-imagemagick=auto  Auto-detect ImageMagick support [default]
+--with-imagemagick=yes   Enable ImageMagick support
+--with-imagemagick=no    Disable ImageMagick support
+
+
+
+Color Data Precision
+
+
ALE's internal data structures store each color channel within a pixel as
+floating-point data; similarly, arithmetic operations on color channels are
+performed in floating point.  The available data-type configurations are
+listed below, with typical data sizes indicated in parentheses.  

+
+--with-colors=single   Use C++ 'float' data type (32-bit)  [default]
+--with-colors=double   Use C++ 'double' data type (64-bit)
+
+
+
+
+Coordinate Data Precision
+
+
+
In general, coordinate transformations used by ALE produce results outside of
+the set of integers; hence, coordinates are treated as floating-point data.
+The two available data-type configurations are listed below, with typical data
+sizes indicated in parentheses.

+
+--with-coords=single   Use C++ 'float' data type (32-bit)  [default]
+--with-coords=double   Use C++ 'double' data type (64-bit)
+
+
+
+
+Thread support
+
+
+

+Threads can improve performance on multiprocessor machines.  POSIX threads are
+currently supported.
+

+
+--enable-threads=auto  Auto-detect thread support.  [default]
+--enable-threads=yes   Enable thread support.
+--enable-threads=no    Disable thread support.
+
+
+
+
+FFTW Support
+
+
+

+This feature is required in order to use the --fl option; it also determines
+the approach to calculation of discrete Fourier transforms used by the
+Irani-Peleg renderer.  For more information on FFTW, see http://fftw.org/.
+

+
+--with-fftw3=auto      Auto-detect FFTW3.  [default]
+--with-fftw3=yes       Use FFTW3 discrete Fourier transform.
+--with-fftw3=no        Use built-in discrete Fourier transform.
+
+
+
+
+
+Enable --wmx
+
+
+

+This build option is required in order to use the --wmx option.  If
+--enable-wmx is specified, it is expected that fork() and execlp() calls
+are available.
+

+
+--enable-wmx=auto      Automatically detect whether to enable --wmx
+--enable-wmx=yes       Enable --wmx
+--enable-wmx=no        Do not enable --wmx
+
+
+
+
+Getsize
+
+
This build option is required to obtain additional output from --ui=tty.  If
+TIOCGWINSZ is not defined in <sys/ioctl.h>, however, additional output will not
+be provided even if --enable-getsize is specified at build time.
+

+
+--enable-getsize=auto   Check for TIOCGWINSZ at build time.  [default]
+--enable-getsize=yes    Configure to attempt to use TIOCGWINSZ
+--enable-getsize=no     Do not attempt to use TIOCGWINSZ
+
+
+
+
+
+Assertions
+
+
+

+Finding bugs within ALE, or within custom modifications to ALE, can be
+simplified by enabling run-time assertions.  These checks enforce conditions
+believed to be necessary or desirable for correct program operation.  If a
+condition is not satisfied, ALE will abort and display a message indicating the
+failed assertion.
+

+
+--enable-assertions    Enable assertions.  [default]
+--disable-assertions   Disable assertions.
+
+
+
+
+
+Cross-compilation
+
+
For cross-compilation, it may be necessary to specify both host and build
+machine types, using the configure --host and --build options.  For more
+information on these options, see the file 'INSTALL' in the source package.

+
+
+Further details
+
+
General operation of the configure script is described in more detail in the
+file 'INSTALL' in the source package.

+
+
+
+  To-do list
+  This article contains a tentative list of future versions and features.
+
+
+

+
+	0.9.0
+
+
+
+
+
+
+Argument scope
+
  • Fix bugs in argument scope handling.
    • 
+

+
+
+
+Multiple-pass registration
+
    
+
  • Revise alignment algorithm to allow multiple passes for less sensitivity to noise and better estimation of tonal certainty.
    • 
+

+
+
+3D scenes and depth recovery
+
    
+
  • Revise 3D scene reconstruction algorithm to perform acceptably on a wider variety of scenes.
    • 
+

+
+
+PSF windowing and infinite-support PSFs for Irani-Peleg rendering
+
    
+
  • Add syntax for PSF windowing and new PSF types with infinite support, including the gaussian kernel, suggested by HJ Hornbeck.
+
    • 
+

+
+
+Variable lighting
+
    
+
  • Add a facility for handling variation in lighting between input frames.
    • 
+

+
+
+Interchange formats
+
    
+
  • Add support for a commonly-used interchange format, such as autopano pto,
+suggested by Peter Miller.
    • 
+

+
+
+
+Raw file handling
+
    
+
  • Use Dave Coffin's dcraw program to extract information from raw files,
+including pixel data, as well as black level and other meta-data, as suggested
+by Gregory Maxwell.
    • 
+

+
+

+
+	Abstract and partial transformations
+
+
    
+
  • Add a generic 2D transformation class, supporting partial transformations.
+  
    •  'partial transformation', as used here, means that it is expected that some
+    points will fail to map.
+  
    
+
  •  Add a partial 2D transformation class with constructor taking as arguments
+  a pair of 3D projective transformations and a 3D model.
+

+

+
+

+
+	File scoping
+
+
  •  Add new file-scoped options
+  
    •  Irani-Peleg
+  
    •  black level
+  
    •  alignment type
+  
    •  focus details
+  
    
+

+

+

+
+	Irani-Peleg for 3D models
+
+
  •  Modify existing Irani-Peleg code to use generic (partial) 2D transformations.
+  
    •  in combination with the above, this should allow the algorithm to operate
+    on 3D models.
+  
    
+  

+

+

+
+	Focus bracketing for depth-of-field expansion
+
+
  •  Add facilities for handling depth-of-field and focus bracketing in input
+  image sets, as suggested by Viktors Rotanovs and Gregory Maxwell.  This
+  change will likely involve:
+  
    •  using the 3D model for depth data, as suggested by Gregory Maxwell
+  
    •  using user-provided (file-scoped) focus details to determine depth of field
+  
    •  using variable PSF in the Irani-Peleg algorithm, as suggested by Gregory
+    Maxwell
+  
    •  developing an approach to handle the incremental (non-Irani-Peleg) case.
+  
    
+  

+

+

+
+Output image characteristics
+
+
  • Allow specification of output image characteristics, including exposure
+(e.g., gamma) and channel offsets within a pixel.
+  

+

+

+
+Output devices
+
+
  • Add support for specifying output devices, such as LCD monitors, to
+allow shorthand customization of exposure (e.g., gamma) and other
+characteristics, such as channel offset in the case of LCD screens for sub-pixel
+anti-aliasing.
+  

+

+

+
+Weight and certainty upper bounds
+
+
  • Add support for specifying weight and certainty upper bounds for
+rendering, either as an absolute constraint or relative to average
+weights, so that the overall contributions to an output pixel (or channel) are
+constrained by weight.  
+
+  

+

+
+

+
+Time locality
+
+
  • In combination with weight and certainty upper bounds, time locality could be
+used to determine which frames are used to generate an output pixel.  As a
+special case of this, video stream processing could favor frames
+having the smallest time difference from the target frame.
+  

+

+

+
+
+
+

+
+	1.0.0 (Stable)
+
+
+
+

+
+	Performance
+
+
  •  Refine rendering and alignment code for better performance.
+  

+

+

+Synchronized frame set syntax
+
  • Add syntax to identify synchronized frame sets.

+

+

+
+	Internationalization
+
+
  •  Enhance the command-line interface in preparation for i18n.  (?)
+  
    •  e.g., syntax for identifying synchronized frame sets
+  
    
+
  •  Internationalize the command-line interface and help text to accommodate
+  translations.
+  

+

+

+
+	Technical Manual Updates
+
+
  •  Update the Technical Manual for information regarding 3D operation.
+

+

+

+
+
+
+

+
+	Unsorted
+
+
+
+
+

+
+	Documentation
+
+
  •  Generate correctly indented book-level tables of contents when rendering
+the complete set of manuals.
+  
  • Add a tutorial, and credit Metin Toyran for suggesting a step-by-step
+    guide.
+  
  •  Remedy meaningless page numbers for book title pages in the set
+  ToC.
+  
  • Complete migration of existing documentation from the localhost sub-directory,
+    removing superfluous license terms in the footers.
+  
  • Centralize licensing and authorship information (e.g., there should be only
+    one COPYING file and only one AUTHORS file).
+  
  • Include license and copyright terms for the doc tree Makefile
+    as copyright notices in the AUTHORS and/or COPYING files (or equivalent).
+  
  • Complete the documentation.
+  
  • Revise the user manual for new features and syntax.
+    
      
+    
    • Document new scoping operators {}, [], and [<>].
+    
    • Document other changes in UI, including regularization of syntax.
+      
        
+      
      • in particular, commas can no longer appear in single-argument options
+        when using assignment-delimited syntax; use space-delimited syntax
+        instead.  This behavior is inconsistent with 0.8.4.
+      
        • 
+      
      
+    
      • 
+    
    
+

+

+

+
+	Integer-value routines
+
+
  •  Add facilities for manipulating images storing color as integer-valued data,
+  possibly as library routines.
+

+

+

+
+	Library
+
+
  •  Move image-processing routines into a library that can be used by other 
+  programs.
+

+

+

+
+	Language Bindings
+
+
  •  Add bindings for other programming languages.
+

+

+

+
+  Packaging
+
+  

+  
+    Complete Package
+  
+
  •  Investigate options for distributing a 'complete' package including full
+  revision history, pre-built documentation (if the ordinary distribution does
+  not include this), and, possibly, example image sets.  Direct download,
+  bittorrent and CD are the most prominent candidates for distribution.
+  
      
+  
    •  In the case of CD distribution, information should probably be added to the
+    manuals regarding how to update CD-provided program source.
+  
      • 
+  
    
+  
    • 
+  

+
+  

+  
+    Windows Package
+  
+
    
+
  •  Investigate options for creating and distributing a combined source and

+		
+Input and output files can be any of the formats supported by
+ImageMagick.
+

+
File handler:     PPM

+		
+Input files must be PPM, and output files are written as PPM.
+

+

+
+Note that many external programs, including ImageMagick's command line utilities, can be used to
+convert between PPM and other formats.
+
+See the README included in the source distribution of ALE for more information about
+compile-time configuration of file handlers.
+
+

+3D Scene Reconstruction (Experimental)
+
+
In general, 3D modeling of scenes may allow handling of cases that per-frame
+projective transformations do not allow, such as registering frames having
+different viewpoints over a non-flat or specular scene, or recovery of depth
+from frames having different viewpoints.  ALE's implementation of 3D scene
+reconstruction is considered experimental in versions prior to 0.8.3.

+
+Models
+
+
The method of modeling used in 0.8.2 and later is spatial subdivision based on
+regions of interest, followed by iterative update of the estimated occupancy
+and color of each region of interest.  (For a general discussion of occupancy,
+see Hans Moravec's work on depth recovery.)  In 0.8.1, the method of modeling
+is decomposition and deformation of a surface.  In earlier versions, a
+per-frame, per-pixel model of depth is used.

+
+Recovered Color and Depth Output
+
+
The color and depth output options provide a reconstruction of the scene as
+viewed from a particular frame's vantage point, or from an arbitrary camera
+view [0.8.2 and later].  In 0.8.2 and later, normalization of output values by
+accumulated occupancy can optionally be disabled for unfiltered views.  Version
+0.8.3 adds support for options --et and --3dpx, which can be useful for 3D
+cropping applications.  --et specifies the minimum accumulated weight required
+for a pixel to be defined, allowing refinements of crops based on clip planes
+(--rc and --fc) established prior to scene
+reconstruction, whereas --3dpx specifies a region of space to be removed 
+after scene reconstruction.  0.8.3 uses depth image pixels to determine such spatial regions,
+leaving the pixels undefined, whereas 0.8.4 removes scene geometry prior to
+rendering, allowing rendering of background objects after the foreground has been removed.

+
+
+--3dv <n> <o>     Render, to file <o>, colors as viewed from frame <n>.
+--3dd <n> <o>     Render, to file <o>, depths as viewed from frame <n>.
+--3dvp <args> <o> Render, to file <o>, colors viewed with projective <args>.  [0.8.2 and later]
+--3ddp <args> <o> Render, to file <o>, depths viewed with projective <args>.  [0.8.2 and later]
+                    <args> are W H V x y z P Y R:
+                         W    image width.
+                         H    image height.
+                         V    camera view angle.
+                         x    translation x component.
+                         y    translation y component.
+                         z    translation z component.
+                         P    rotation around x-axis.
+                         Y    rotation around y-axis.
+                         R    rotation around z-axis.
+--occ-norm        Normalize output with accumulated occupancy.          [default]     [0.8.2 and later]
+--occ-nonorm      Don't normalize output with accumulated occupancy.                  [0.8.2 and later]
+--et <x>          Set encounter threshold <x> for defined pixels.  [default is 0]     [0.8.3 and later]
+--3dpx <args>     Exclude a specified spatial volume following full-scene             [0.8.3]
+                  reconstruction, assuming a single depth at each point
+                  in the output.  <args> are:
+                         <xmin> <xmax> <ymin> <ymax> <zmin> <zmax>
+--3dpx <args>     Exclude a specified spatial volume following full-scene             [0.8.4 and later]
+                  reconstruction.  <args> are:
+                         <xmin> <xmax> <ymin> <ymax> <zmin> <zmax>
+

+
+Filtering [0.8.4 and later]
+
+
Version 0.8.4 adds support for filtering color values from the inputs to
+produce final color renderings.  This is now the default.  Determining surface
+depth and gradient for filtering the inputs draws from a set of depth pixels
+within a disc whose radius can be specified with the --3d-dmr and --3d-fmr
+options.

+
+
Filtering color from views distributed on a disc (about the camera origin) of
+specified aperture allows simulation of focus effects; such effects can be
+controlled with the --focus option.

+
+
+--3d-filter       Use filtering for 3D color output.                    [default]
+--3d-nofilter     Don't use filtering for 3D color output.
+--3d-dmr <x>      Set radius for filtering median depth to <x>        [default 0]
+--3d-fmr <x>      Set radius for filtering median diff to <x>         [default 0]
+--focus <ft> <op> Create focus region with type <ft> and options <op>:
+                     Focus type:
+                        d <d>           focus at distance <d>
+                        p <x> <y>       focus at point (x, y)
+                     Space-separated options may include zero or more of:

+
+Camera parameter adjustment
+
+
In versions 0.8.1 and later, camera parameters can be adjusted according to
+control points to decrease the error between points in different frames.
+Perturbation bounds for adjustment can be specified, including an additional
+upper bound on view angle perturbation, and a stereo threshold can be set for
+discarding control points after adjustment is complete.  An initial camera view
+angle can also be specified.  Versions 0.8.2 and later allow calculation of
+error by median rather than mean, and also allow disabling of adjustment of
+orientation and/or position.

+
+
+--view-angle <x>  Set the initial diagonal view angle to <x> degrees.
+                     (Default is 43.7 degrees or device-specific.)

+

+
+Transformation data files [0.8.2 and later]
+
+
Transformation data file options allow reading and writing of camera position,
+orientation, and view angle information.

+
+
+--3d-trans-load=x Load initial transformation settings from file x                       [0.8.2 and later]
+--3d-trans-save=x Save final transformation data in file x                               [0.8.2 and later]
+

+
+Transformation data file format [0.8.2 and later]
+
+
The transformation data file uses the following format, starting with a version
+command, and then describing view angle and euclidean transformation of each
+frame in turn:

+
+
+W 0
+V <view angle>
+E <width> <height> <X> <Y> <Z> <P> <Y> <R>
+V <view angle>
+E <width> <height> <X> <Y> <Z> <P> <Y> <R>
+.

+V <view angle>
+E <width> <height> <X> <Y> <Z> <P> <Y> <R>
+

+
+Model costs [0.8.1 only]
+
+
After the cameras are adjusted, a 2D surface is decomposed and deformed to
+reduce local cost measures, calculated from angles between neighboring
+triangles, edge lengths, and differences in color between different views.
+Multipliers for edge length and angle costs can be specified on the
+command line.

+
+
+--ecm <x>         Set edge length cost multiplier <x>.         [default is 0.001]  [0.8.1 only]
+--acm <x>         Set angle cost multiplier <x>.               [default is 0.001]  [0.8.1 only]
+

+
+Model rules [0.8.2 and later]
+
+
In versions 0.8.2 and later, clip planes can be specified, and a color falloff
+exponent for pairwise occupancy estimation can be specified.  Larger exponents
+are more forgiving of color differences between pixels in different frames.
+In versions 0.8.3 and later, error contributions from cameras outside of the
+generating pair can be assigned non-zero multipliers (--tcem), the
+number of occupancy and color update iterations can be specified
+(--oui), the number of points in space generated for each pixel
+pair can be specified (--pa), and the type of frame pairings can
+be specified (--pc).

+Alignment
+
+
Alignment compares each supplemental frame in the sequence with an intermediate
+incremental rendering known as the alignment reference image.  Based on this
+comparison, a transformation is assigned to the supplemental frame.  Many
+different transformations can be assigned before alignment of the frame is
+complete.

+
+
This manual page offers an overview of alignment options; see also .

+
+Transformations
+
+
The variables used to adjust alignment are called transformations; they map
+points from the source image coordinate system to a target coordinate system
+(the rendering coordinate system).

+
+
ALE supports three transformation classes -- translational, euclidean, and
+projective -- as well as barrel/pincushion distortion correction.  The
+translational class applies only translations to the inputs, changing only the
+positions of images; the Euclidean class applies translations and rotations;
+and the projective class applies general projective transformations.
+Additionally, barrel/pincushion distortion correction can be applied to each
+frame.  The Euclidean class is most appropriate for use with scanners, or as a
+first pass for projective transformations.  The projective class and
+barrel/pincushion distortion correction are most appropriate for use with
+cameras.  Except when capturing flat scenes, ALE does not correct perspective
+changes, so movement of cameras should ideally be constrained so that no large
+translations occur.

+
+Transformation Class Options
+
+--translation     Only adjust the position of images
+--euclidean       Adjust the position and orientation of images [default]
+--projective      Use projective transformations.  Best quality, but slow.
+
+
+
For more information on barrel distortion correction, see .

+
+Transformation data file options
+
+
Transformations used in alignment can be loaded from, or saved to, a
+transformation data file..  This can be useful when performing alignment in
+several passes, or when refining rendering options.  A transformation data file
+is required for barrel/pincushion distortion correction.  For more information, 
+see .

+
+--trans-load=x    Load initial transformation settings from file x
+--trans-save=x    Save final transformation data in file x
+
+
+Alignment following
+
+
The --follow option hints that frames tend to be more closely aligned with
+adjacent frames in the sequence than with the original frame.  --identity 
+indicates that frames tend to closely align with the original frame.  These hints can be
+useful even when initial alignment information is loaded from a file.

+
+--follow          Frames align closely with their predecessor.  [default]
+--identity        Frames align closely with the original frame.
+
+
+Match statistics
+
+
The match statistic indicates how well a transformed frame aligns with the
+alignment reference image; it is used to select or reject transformations
+during alignment.  After alignment of a particular frame is complete, ALE
+displays the corresponding final match statistic.  If the value is close to
+100%, then the frames are well aligned; very low values can indicate
+misalignment; but even frames that are very well aligned typically do not
+achieve 100% alignment.  For improving image quality, ALE works most
+effectively when match values are lower than 100%.

+
+Match threshold
+
+
A match threshold can be specified; no images with final match statistics
+falling below this threshold will contribute to the final output.

+
+--threshold=x     Min. match threshold; a perfect match is 100.  (0 is default)
+
+
+Alignment failure
+
+
When an image fails to meet the match threshold, a transformation is still
+assigned to the frame (e.g., for writing to a transformation data file).  The assigned
+transformation can be either the optimal alignment found (this is default) or
+the default transformation.

+
+--fail-optimal    Frames beneath threshold are aligned optimally.  [default]
+--fail-default    Frames beneath threshold keep their default alignment.
+
+
+Alignment error metric exponent
+
+
The function calculated at each pixel to determine the match statistic is of
+the form (a-b)x.  The exponent value x
+is 2 by default.  Larger numbers give greater influence to smaller image
+features.

+
+--metric=x        Set the alignment error metric exponent.       (2 is default)
+
+
+Alignment Channel Options
+
+
In calculating the per-pixel error metric, there are three ways in which ALE
+can handle color channels.  By default, ALE adds the channels before
+calculating the match, but it can also be configured to rely solely on the
+green color channel, or to use all three channels separately.

+
+--align-all       Align images using all color channels
+--align-green     Align images using the green channel
+--align-sum       Align images using a sum of channels [default]
+
+
+Monte Carlo Alignment
+
+
As aligning large images can take a long time if all pixels are examined, it
+is often desirable to examine a smaller subset of pixels.  The Monte Carlo
+alignment option samples a subset of pixels, specified as a percentage of the
+total pixel count, with smaller numbers providing faster, but less precise,
+alignment.  For defaults, see .

+
+--mc <x>          Align using, on average, x% of available pixels (0 < x < 100)
+--no-mc           Align using all pixels.
+
+
+Alignment weight map
+
+
Typically, measured differences at each pixel in the alignment reference
+image contribute equally to the match statistic.  To weight pixels differently,
+a weight map can be used.  The scale of the map should correspond with that of
+the alignment reference image, and if the upper-left corner of the map does not
+coincide with the upper-left corner of the first frame in the sequence, then a
+non-zero offset should be specified to indicate the difference.  See also .

+
+--wm <f> <x> <y>  Use weight map image <f> at offset (<x>, <y>)
+
+
+Frequency weighting
+
+
If ALE is compiled with FFTW support, then a high-pass-filtered version of
+the alignment reference image can be used to weight reference image pixels'
+contributions to the match statistic.  Frequency limiting can occur as a
+fraction of the highest horizontal frequency, the highest vertical frequency,
+or the highest average frequency.  Limit values should range between 0 (pass
+all) and 1 (pass none).  If any limit is assigned a value of 1, no alignment
+will occur, since all frequencies will have been excluded.  An output file can
+optionally be specified for high-pass filtered data.

+
+--fl <h> <v> <a>  High-pass filters: horizontal <h>, vertical <v>, average <a>.
+--flshow <o>      Write high-pass filtered data to file <o>.
+
+
+Certainty weighting
+
+
Certainty weighting causes contributions to alignment error to be weighted
+by certainty values.

+
+--cw              Weight alignment error by certainty.
+--no-cw           Don't weight alignment error by certainty. [default]
+
+
+Algorithmic weighting
+
+
This option writes the current alignment reference image and definition map
+to specified files, executes a specified program with these arguments, and then
+reads back alignment weights.  This option requires POSIX libraries, and
+requires that ALE have been built with POSIX support enabled.

+
+--wmx <e> <r> <d> Write reference <r>, definition <d>, execute `<e> <f> <d>`,
+                  read weights <r> back.
+
+
+Perturbation
+
+
The perturbation size determines the magnitude by which alignment parameters
+are changed.  The size is initially set to be large, allowing large changes in
+alignment to be evaluated, and is reduced as the locally optimal alignment is
+found for each size.  When this size drops below a specified lower bound, the
+frame is considered to be aligned.

+
+Perturbation bounds
+
+
These options determine the upper and lower bounds for perturbation size.  The
+perturb-upper and perturb-lower bounds apply to rotation (in arclength),
+translation (in pixels), and the movement of the boundaries of a projected
+frame (in pixels).  By appending the '%' character, values may optionally be
+specified as a percentage of the number of pixels in the smallest image
+dimension.  The rot-upper bound disables rotational perturbation above a
+certain perturbation size (in degrees).  To disable alignment, set
+perturb-upper to zero.

+
+--perturb-upper=x Perturbation upper bound pixels/arclength    (14% is default)
+                     ('x%' uses a fraction of the smallest image dimension.)
+--perturb-lower=x Perturbation lower bound pixels/arclength   (.125 is default)
+                     ('x%' uses a fraction of the smallest image dimension.)
+--rot-upper=x     Rotation-specific upper bound in degrees    (32.0 is default)
+
+
+Barrel/pincushion distortion adjustment multiplier and rate
+
+
When using barrel/pincushion distortion parameters, any frame-to-frame
+adjustments to these parameters are made in a manner dependent on the
+perturbation size.  A multiplier, the barrel distortion adjustment multiplier,
+is used to determine the perturbation of these parameters, based on the generic
+perturbation size.  Additionally, the frame-to-frame rate of change of each
+barrel distortion parameter can be limited to a specified maximum.  To disable
+frame-to-frame adjustment of barrel/pincushion distortion parameters, set
+bda-mult to zero.  Setting bda-rate to zero disables rate limitation.

+
+--bda-mult=x      Barrel distortion adjustment multiplier   (0.0001 is default)
+--bda-rate=x      Barrel distortion rate of change maximum  (0.0004 is default)
+
+
+Level of detail
+
+
Alignment at large perturbation sizes is usually carried out on
+reduced-detail images.  To disable this, set lod-max to
+log2(perturb-upper).

+
+--lod-max=x       LOD scale factor is max(1, (2^floor(x))/perturb)  (1 is def.)
+
+
+Perturbation Types (experimental)
+
+
Perturbations are normally performed in output image coordinates.  To perform
+perturbations in source image coordinates, specify --perturb-source.

+
+--perturb-output  Apply perturbations in output image coordinates. [default]
+--perturb-source  Apply perturbations in source image coordinates.
+
+
+Global Searching
+
+
In cases where important image features do not have sufficient overlap using
+default alignment parameters (determined by --identity and
+--follow), a number of translations can be applied to the default
+parameters in order to find a new alignment starting point.  Since this process
+searches the entire region of the alignment reference image, it is called a
+global (as opposed to local) search.  To avoid misalignment, a minimum overlap
+area can be specified.  In versions 0.8.1 and later, the search type 'points'
+searches for a control point metric minimum.

+
+--gs <type>       Set global search to <type>, one of:
+                     local     Local alignment only [default]
+                     inner     Alignment reference image inner region
+                     outer     Alignment reference image outer region
+                     all       Union of inner and outer
+                     central   inner if below threshold or better; else, outer.
+		     points    Align by control points.  Ignores gs-mo.   [0.8.1 and later]
+
+--gs-mo <x>       Set <x> pixel min. overlap for global search. (16 is default)

+Rendering Chains
+
The ALE incremental renderer is configured using rendering chains.  Rendering chains are
+constructed hierarchically from: invariants, SSFEs (scaled sampling filters
+with exclusion), SSFs (scaled sampling filters), and sampling filters.  Each of
+these components is described in a section below.  Defaults are outlined in the
+final section.

+
+Chains
+
+
The chain is the top level of the rendering chain hierarchy, and is composed of a
+sequence of invariants.  Syntactically, a chain is specified as a number of
+invariants separated by commas:

+
+
invariant1,invariant2,invariant3,...,invariantn

+
+
Each rendered pixel is assigned a value at the first invariant whose weight
+exceeds the weight threshold, or otherwise at the last invariant in the sequence.

+
+Chain Options
+
+
+--wt <w>          Set weight threshold for defined pixels [default is 0.8 in v0.8.0; 0.1 in v0.8.1 and later]
+--dchain <g>      Use chain <g> to render the default output.
+--ochain <g> <o>  Use chain <g> to render output file <o>.
+--achain <g>      Use chain <g> to render the alignment reference image.
+--3d-chain <g>    Use chain <g> by default to render 3d output.  [0.8.4 and later]
+
+

+
+Chain Examples
+
+
+             triangle:2                           ALE 0.6.0 merging (roughly)
+             fine:box:1                           Drizzling (roughly)
+             fine:sinc*lanc:8                     High-frequency preservation
+             last:nex:sinc*lanc:8                 Useful for video stabilization
+             fine:box:1,triangle:2                Multi-resolution rendering
+             fine:sinc*lanc:8,sinc*lanc:8         Multi-resolution rendering
+

+
+Invariants
+
+
Invariants determine whether the rendered pixel value should be taken from a
+single frame, or from an average of all frames.  If from a single frame, it can
+be the first, last, minimal, or maximal pixel value.  Averages include mean
+and, in versions 0.8.1 and later, the median.  By default, the mean is used.
+(Note that using the median value may require allocation of a quantity of
+memory linear in the number of frames.)  The syntax is as follows:

+
+
+
+
+
+
+
+
+
+
+
+
Invariant types
SyntaxDescription
avg:<SSFE>Mean value
median:<SSFE>Median value
max:<SSFE>Maximum value
min:<SSFE>Minimum value
first:<SSFE>First value
last:<SSFE>Last value
<SSFE>Same as avg:<SSFE>

+
+Scaled Sampling Filter with Exclusion (SSFE)
+
+
SSFEs qualify SSFs, indicating whether exclusion regions should be honored.

+
+
+
+
+
+
+
+
Scaled sampling filter with exclusion (SSFE) types
SyntaxDescription
ex:<SSF>Honor exclusion regions
nex:<SSF>Don't honor exclusion regions
<SSF>Same as ex:<SSF>

+
+Scaled Sampling Filter (SSF)
+
+
SSFs indicate whether filtering should occur at the resolution of the output
+image, or at the minimum of input and output image resolutions.  The former prevents loss
+of details; the latter prevents aliasing.

+
+
+
+
+
+
+
+
Scaled sampling filter (SSF) types
SyntaxDescription
fine:<SF>Filter at full output image resolution
coarse:<SF>Filter at minimum resolution
<SF>Same as coarse:<SF>

+
+SSF Options
+
+--afilter <s>     Use SSF <s> to interpolate points in alignment.
+

+
+Sampling Filter (SF)
+
+
SFs are used to limit bandwidth.  Primitive functions and pointwise multiplication of these
+functions (windowing) are available.

+
+
+
+
+
+
+
+
+
+
+
Sampling filter (SF) types
SyntaxDescription
sincsinc filter
lanc:<x>Lanczos, diameter x.
triangle:<x>Triangle, diameter x.
box:<x>Box, diameter x.
zeroZero function
<f>*<f>Pointwise multiplication (windowing)

+
+Defaults
+
+
ALE defaults are as follows:

+
+
                     dchain         Varies by default setting
+                     achain         Varies by default setting

+Control Points
+
+
Control points are used for 2D and 3D alignment, and to constrain 3D scene

Control points can be one of three types:

+
+Type A control points
+
+
Type A control points specify a sequence of 2D points, one for each frame,
+where each point is specified as a pair of floating point numbers.  If there is
+no data for a frame, then "nan" should be specified.  E.g.:

+
+
A 20  30  nan nan 10  10  10  15
+A 23  22  25  25  nan nan nan nan
+

+
+Type B control points
+
+
Type B control points specify a 3D coordinate.  E.g.:

+
+
B 10 30 -400
+B 10 15 -425
+

+
+Type C control points
+
+
Type C control points specify both 2D and 3D data.  There is a single 3D point
+specified, as well as one 2D point for each frame.  The 3D point appears at the
+end of the line.  E.g.:

+
+
C 20  30  nan nan 10  10  10  15  10 30 -400
+C 23  22  25  25  nan nan nan nan 10 15 -425

+
+  Default Settings
+
+
ALE offers five different default settings, each of which emphasizes
+image quality, speed, or some other rendering characteristic, as follows:

+
+--q0              Low quality, high speed. [default]
+--qn              Low noise, moderate speed.
+--q1              Moderate quality and speed.
+--q2              High quality, low speed.
+--qr              Range-extended high quality.
+
+
+
These settings specify defaults for other options: --dchain,
+--achain, --3d-chain, --ips, --exp-extend, and
+--cx.  For more information about these options, see  and .  Details regarding
+these defaults are provided in the following sections.

+
+High speed (--q0)
+
+
--q0 emphasizes speed over image quality.  This option is default, and
+sets other options' defaults as follows:

+
+--dchain fine:box:1,triangle:2
+--achain triangle:2
+--ips 0
+--exp-noextend
+--no-cx
+--3d-chain fine:box:1,triangle:2
+
+
+
+Low noise (--qn)
+
+
--qn emphasizes low noise over resolution and rendering speed, and
+sets the following defaults:

+
+--dchain sinc*lanc:6
+--achain sinc*lanc:6
+--ips 0
+--exp-noextend
+--no-cx
+--3d-chain sinc*lanc:6
+
+
+
+
+Balanced quality and speed (--q1)
+
+
--q1 balances image quality and rendering speed, offering higher
+resolution than --qn.  As this option uses median values, its memory use
+is linear in the number of input images (rather than constant).

+
+--dchain median:fine:sinc*lanc:8,triangle:2
+--achain triangle:2
+--ips 0
+--exp-noextend
+--no-cx
+--3d-chain median:fine:sinc*lanc:8,triangle:2
+
+
+
+
+High quality (--q2)
+
+
--q2 favors image quality over rendering speed, offering greater
+emphasis for high-frequency details than --q0, --qn,
+or --q1.  It depends on the --lpsf and
+--nlpsf options, which can be set indirectly via the
+--device option.  (More information about these options can be
+found in  and .)  --q2
+sets the following defaults:

+
+--dchain triangle:2
+--achain triangle:2
+--ips 4
+--exp-noextend
+--no-cx
+--3d-chain median:fine:sinc*lanc:8,triangle:2
+
+
+
+
+Range extension (--qr)
+
+
--qr is similar to --q2, but offers improved
+rendering when input images have been taken with unequal exposures.  In other
+cases, it may exacerbate noise in light and dark regions.  This option sets the
+following defaults:

+
+--dchain triangle:2
+--achain triangle:2
+--ips 6
+--exp-extend
+--cx 0.7
+--3d-chain median:fine:sinc*lanc:8,triangle:2

+Devices
+
+
Device specification is optional.  Specifying a device allows automatic
+determination of point-spread functions,
+refinement of the correspondence between incident light and pixel values (e.g.
+power law), and refinement of certainty calculation.

+
+
--device <d>      Set the capture device to <d>.

+
+
These device options are described in more detail below.

+
+Canon 300D (Digital Rebel)
+
+
Direct support for CRW files depends on the ImageMagick configuration, and
+may not be available on all platforms.  Dave Coffin's dcraw program, invoked with
+arguments -d -4, will produce a raw, linear PPM file suitable for use with this
+device configuration.  JPEG files produced by the 300D cannot be directly used
+as inputs for this configuration, since they are gamma-corrected rather than
+linear.

+
+OV7620
+
+
Standard OV7620 drivers may not include options for setting raw RGB or linear
+modes.  Linux users may apply a driver patch to access
+these modes.  Setting the module option rgb_raw=2 places the camera
+into the desired mode.

+
+XVP610
+
+
Users of XVP610 cameras and Linux may wish to apply a driver patch.  This version of ALE expects that this patch has been applied.

+Extended PPM (EPPM) Files
+
+
EPPM is an extension to the PPM file format that allows specification of
+metadata.  The header of an EPPM file conforms to the following template:

+
+

+# Tag1: Value
+# Tag2: Value
+# Tag3: Value
+# .
+# .
+# .
+Width Height Maxval

+

+
+
Tags recognized by ALE are outlined below.

+
+Black level
+
+
The black level tag specifies a value that should be subtracted from
+all pixels in order to achieve linearity.  A modified version of dcraw (darcs repository) can be used to generate files
+containing this tag.

+
+
# Black-level: <value>
+

+
+Exposure tags
+
+
Exposure tags can be used for determining tonal registration through
+specification of shutter speed, aperture, and ISO sensitivity (or gain).

+
+
# Shutter: <value>
+# Shutter: 1/<value>
+# Aperture: <f-number>
+# ISO: <value>

+Exclusion Regions
+
+
ALE offers exclusion regions as a way to disallow certain areas from being
+used in alignment and (optionally) rendering.  Spatial coordinates are
+expressed in the rendering coordinate system (prior to scaling).  In cases
+where the default transformation is used with the original frame, this is
+identical to the unscaled original frame coordinate system, taking the
+upper-left corner to be (0, 0).  Frame numbering begins with 0, which represents
+the original frame.

+
+Rectangular Exclusion
+
+
All specified volumes are excluded from alignment (except where they affect
+the alignment reference image), and are excluded from rendering by default.
+(See  for information on how to ignore exclusion
+regions.)  Exclusion region syntax is as follows:

+
+--ex <args>       Exclude a specified volume.
+                     <args> are space-delimited horizontal,

+
+File Output
+
+
File output options determine the format in which rendered images are written,
+and how frequently they are written.  Depending on the compilation options used,
+available file output options vary.

+
+Output Color Depth
+
+
Output color depth of 8 or 16 bits of precision per color channel can be specified,
+for 24-bit or 48-bit color, respectively. 
 
+
+--8bpc            Write 8 bit per channel output [default]
+--16bpc           Write 16 bit per channel output
+
+
+
+Extension-based file type determination
+
+
If ALE has been built with ImageMagick support, then the output file type can
+be determined automatically by file extension.  This is the default behavior
+for ImageMagick builds.  The --auto flag explicitly specifies that
+the default behavior should be used; it generates an error on builds compiled
+without ImageMagick support. 
 
+
+--auto            Determine file type automatically
+
+
+
+PPM Output
+
+
All builds of ALE support PPM output.  PPM can be written in plain (ASCII) or
+raw (binary) format.  If ALE has been built without ImageMagick support, or if
+the file type cannot be automatically determined by file extension, then raw
+PPM output is used by default.

+
+--raw             Write raw PPM output
+--plain           Write plain PPM output
+
+
+
+Incremental Output
+
+
By default, ALE writes intermediate results periodically throughout the rendering
+process.  This behavior can be disabled, however, so that output is written only
+after rendering is complete.

+
+--inc             Produce incremental output.  [default]
+--no-inc          Don't produce incremental output.
+
+
+
+Undefined Values
+
+
By default, ALE colors undefined values black.  To assign nearest-neighbor colors
+to undefined pixels, the --def-nn option can be used.
+

+
+--def-nn <R>      Use nearest-neighbor defined values within 
+                  radius <R>, zero outside.  Default radius is 0.

+Image Files
+
+ALE can be configured at compile time to use one of two different file
+handlers.  Execute 'ale --version' to determine which file handler is being
+used.  The table below outlines the supported formats for each file handler.
+
+
+
+
+
+
+
+
+
+
+
Supported image file formats
Version MessageFile Types Supported

+File handler:     ImageMagick
+
+Input and output files can be any of the formats supported by
+ImageMagick.
+
+

+File handler:     PPM
+
+Input files must be PPM, and output files are written as PPM.
+

+
+Note that many external programs, including ImageMagick's command line utilities, can be used to
+convert between PPM and other formats.
+
+See the README included in the source distribution for more information about
+compile-time configuration of file handlers.
+
+
Usage of extended PPM syntax for specifying image metadata is outlined in .

+
+
+
+

+

+Command-line syntax for Version Information
+
+The following command-line invocation can be used to print version
+information and build options:
+
+ale --version
+
+The following is sample output from this invocation:
+
+ALE Version:      
+File handler:     ImageMagick

+Point Spread Functions
+
The ALE Irani-Peleg renderer uses a point-spread function to model the optical
+and electronic properties of the capture device used.  The PSF can be specified
+in terms of one linear and one non-linear component.

+
+PSF specification
+
+
The PSF can be explicitly specified by using one or both of the psf options.

+
+--lpsf <p>        Set linear colorspace point-spread function to <p>
+--nlpsf <p>       Set non-linear colorspace point-spread function to <p>
+
+
+
Available explicit point-spread functions are as follows:

+
+box=<d>           Set the PSF to a box filter with diameter <d>.
+circle=<d>        Set the PSF to a circular filter with diameter <d>.
+stdin             Specify a custom filter at runtime.
+stdin_vg          stdin with vertically-oriented gaps after every 8th pixel.
+<p>+<p>           Summation of two functions
+<p>^<p>           Convolution of two functions.
+<n>*<p>           Multiplication by a scalar <n>.
+
+
+
If a device is known to ALE, then its PSF can be implicitly set with the
+--device option.  (See the device page
+for more information.)  If a device is not specified, then the default linear
+PSF component is box=1.  The non-linear PSF component is disabled
+by default.

+
+Determining the PSF
+
+
The PSF can be approximated based on images of known scenes.  The ALE source
+distribution includes an experimental script that numerically approximates the
+PSF in this way (d2/render/psf/ale-psf-calibrate).  Other, more
+efficient methods for approximating the PSF are likely possible, however.

+
+Rendering
+
Rendering determines how an output image is constructed from a series of
+aligned input frames, and occurs in two stages: incremental rendering and
+Irani-Peleg rendering.  Additional rendering options include exposure
+registration, certainty-weighted rendering, spatial extension, range extension,
+scaling, and Bayer pattern specification.  Experimental options for video
+stream processing are also available.

+
+Incremental Rendering
+
+
The incremental renderer uses configurable rendering chains to determine the
+output image.  It can increase resolution and reduce aliasing, but it cannot
+reduce blur.  For more information on rendering chains, see .

+
+Irani-Peleg Rendering
+
+
The Irani-Peleg renderer uses configurable point-spread functions to model
+blur, which is then reduced by an iterative backprojection technique.  By
+default, mean correction values are used at each iteration step, but median
+correction can also be specified.  For more information about point-spread
+functions, see .  For iteration defaults, see
+.
+
+

+
+--ips <i>         Run <i> iterations.
+--ip-mean         Use the mean correction [default]
+--ip-median       Use the median correction
+
+
+Exposure Registration
+
+
By default, ALE adjusts an exposure model to minimize differences in tone
+between frames.  The option --exp-noregister indicates that exposure
+should be assumed uniform across all frames.  In this case, no adjustment is
+performed.  The option --exp-meta-only indicates that only exposure
+information included in the image files should be used for registration.
+Currently, EPPM is the only type of exposure metadata supported by this option;
+for more information, see .

+
+--exp-register    Register exposure between frames.  [default]
+--exp-noregister  Assume uniform exposure across all frames.
+--exp-meta-only   Use only image metadata for registering exposure.
+
+
+Color Adjustment
+
+
To adjust the color of the output image (e.g., for white balance), the
+--exp-mult= option can be used.

+
+--exp-mult=c,r,b   Adjust all channels by <c>, red by <r>, and blue by <b>.
+
+
+Certainty-weighted Rendering
+
+
The exposure model includes an associated certainty function, which
+quantifies the reliability of sensor measurements.  By default, this function
+is raised to the zeroth power, to obtain uniform certainty for all measurements.
+To specify a different certainty exponent, the option --cx can be
+used.  This option is best used in combination with --exp-extend (see
+below) and --ips.  For defaults, see .

+
+--cx <x>          Render with certainty exponent <x>
+--no-cx           Render with uniform certainty.
+
+
+Scale factor
+
+
Rendering with a larger scale factor results in image output of the specified
+larger scale.  Larger scales can improve alignment precision and output image
+quality, but can also increase alignment and rendering times.

+
+--scale=x         Scale images by the factor x, where x > 0.     (1 is default)
+
+
+Image extents
+
+
The --extend option records pixel data that falls outside of the region of the
+first frame in the sequence.  This can be useful for providing additional
+alignment constraints or creating panoramic image mosaics.  (For mosaics, see
+also the description of the --follow option in .)

+
+--extend          Increase image extents to accommodate all pixel data.
+--no-extend       Don't increase extents; crop to original frame. [default]
+
+
+Exposure extents
+
+
By default, ALE restricts the output range to that of the original frame.
+To adjust the output range to accommodate the ranges of all input frames,
+specify --exp-extend.  For defaults, see 

+
+--exp-extend      Extend range to include all calculated values.
+--exp-noextend    Restrict to the original frame's range.
+
+
+Bayer pattern specification
+
+
Many cameras sample only one color channel per output pixel.  To ignore the
+other channels, a Bayer pattern can be specified.

+
+--bayer <b>       Set the Bayer pattern to <b>, one of:
+                    (clockwise from top left pixel)
+                      rgbg      Red-green-blue-green
+                      gbgr      Green-blue-green-red
+                      grgb      Green-red-green-blue

+
+
+Video stream processing (Experimental)
+
+
If a sequence of frames represents a video stream, then, in addition to
+producing a single output image, ALE can also produce one or more sequences of
+processed frames, corresponding to one or more occurrences of the
+--visp option.  This option has its own associated scaling option,
+as well as an option to show excluded regions as dimmed wherever possible.

+
+--visp <args>     Process a video sequence.
+                     <args> are:
+                         <chain> <stabilization-type> <prefix> <suffix>
+                     <chain> is an incremental rendering chain.
+                     <stabilization-type> is one of:
+                         ma:<x>     Moving average over 2*<x> + 1 frames
+                         sf:<x>     Stabilize to single frame number <x>
+                         identity   Same as ma:0
+                     <prefix> is an output file prefix
+                     <suffix> is an output file suffix
+--visp-scale=<x>  Use scale <x> for VISP output.  (default is 1.0)
+--exshow          For single-invariant chains, show --ex regions dimmed.
+
+
+Video stream processing example
+
+
To mimic the behavior of repeated applications of the 0.6.0
+--replace option over a sequence of frames, the following
+--visp option could be used.

+
+--visp last:nex:triangle:2 sf:0 frame .jpg
+
+
+
For better filtering, the following option could be used instead:

+
+--visp last:nex:sinc*lanc:6 sf:0 frame .jpg

+Transformation Data Files
+
+
Transformation data files are useful when performing alignment in several
+passes or refining rendering options, and are necessary for specifying
+barrel/pincushion distortion parameters.  They also offer a way to manually
+specify alignment when ALE cannot automatically align images.  

+
+Multiple-pass alignment
+
+
To align images in multiple passes, load the saved results of each previous
+pass, as follows:

+
+
$ ale --trans-save=a.t <first pass arguments>
+$ ale --trans-load=a.t --trans-save=b.t <second pass arguments>
+$ ale --trans-load=b.t --trans-save=c.t <third pass arguments>
+.
+.
+.
+

+
+Rendering option refinement
+
+
To refine rendering options using the same alignment, first save the alignment
+for the first option set, and then load the saved alignment information with
+each subsequent option set, setting the perturbation upper bound to zero to
+prevent a new alignment pass from occurring:

+
+
$ ale --trans-save=a.t <first option set>
+$ ale --trans-load=a.t --perturb-upper=0 <second option set>
+$ ale --trans-load=a.t --perturb-upper=0 <third option set>
+.
+.
+.
+

+
+Alignment file syntax (version 2)
+
+
There are two varieties of alignment file syntax that are both read and written
+by ALE 0.7.0.  The most basic of these is version 2.  Version 3 is slightly
+more complex, and is covered in the next section.

+
+
At the highest level, version 2 transformation data files contain the following
+components: (a) a version command, and (b) a sequence of transformation
+commands, one for each supplemental frame.  Each line of text should contain at
+most one command, between which optional comments may be interspersed.  A
+transformation command can be Euclidean, projective, or default.  Euclidean and
+projective commands take several arguments, including the width and height of
+the supplemental frame.  Default commands take no arguments.  Commands are
+outlined in more detail below.

+
+Version command
+
+
The version 2 version command is as follows:

+
+
V 2
+

+
+Euclidean commands
+
+
The structure of a Euclidean command is as follows:

+
+
E <image width> <image height> <x-offset> <y-offset> <rotation-angle>
+

+
+Projective commands
+
+
Projective commands map the four corners of the supplemental frame to four
+points in the rendering coordinate system:

+
+
P <image width> <image height> <top-left-x> <top-left-y> <blx> <bly> <brx> <bry> <trx> <try>
+

+
+Default commands
+
+
Default commands can be explicitly written as follows:

+
+
D
+

+
+
Alternatively, if there are more frames than alignment commands (euclidean,
+projective, or default), then the last supplemental frames in the frame
+sequence will be assigned the default command.

+
+Comments
+
+Comments can be inserted with the following syntax:
+
+
# This comment extends to the end of this line.  I can write anything I want here.
+

+
+Alignment file syntax (version 3)
+
+
Version 3 syntax is required for specifying transformations for the original
+frame, and for specifying barrel/pincushion distortion parameters.  

+
+
In version 3, the first transformation command is associated with the
+original frame, instead of being associated with the first supplemental frame.
+Also, barrel/pincushion distortion commands can precede each projective,
+Euclidean, or default command.

+
+Version command
+
+
The version 3 version command is as follows:

+
+
V 3
+

+
+Barrel/pincushion distortion command
+
+
In version 3, barrel/pincushion distortion commands are supported.  Distortion
+is modeled as a transformation affecting the distance of image features from the
+image center.  The distorted distance is expressed as a polynomial function of
+the undistorted distance.  Zeroth and first order coefficients are fixed or
+automatically determined; additional coefficients can be specified explicitly,
+using the following syntax:

+
+
B <n> <coefficient 2> <coefficient 3> ... <coefficient n+1>
+

+
+
Barrel/pincushion distortion commands should precede the projective, Euclidean,
+or default transformation command for the corresponding frame.

+User Interfaces
+
+
ALE currently supports two user interface types.  The traditional interface
+is the stream interface, which produces only printing characters and
+whitespace.  If ALE is compiled with IOCTL support, additional information can
+be provided through the tty interface, which is default.

+
+
--ui=<type>       Set user interface to <type>, one of:
+                     stream
+                     tty [default]

+
+   Standards compliance:
+
+       -  must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       -  must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';
+   this isn't required, but 'bool' is more common.  */

+# SYNOPSIS
+#
+#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#          LIBS="$PTHREAD_LIBS $LIBS"
+#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#          CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
+dnl
+dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
+dnl 'include' otherwise.
+dnl
+dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
+dnl supports it in the special case that it is the first include directive in
+dnl the given file, or to 'include' otherwise.
+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as
+dnl opposed to the search path specified with '-I' options). Namely, gcc
+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
+dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
+dnl of plain '__STDC__'.

+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything

+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

+# This script attempts to calibrate a filter under ALE for characteristics of a
+# specific device.  It uses the stdin IPC device to configure the filter.

+# The initial filter tested is the box filter, and individual elements
+# of the filter are increased or decreased to determine the effects of
+# such changes.  When the change increases the match with the desired
+# output, it is kept.  Otherwise, the change is backed out.
+#
+# The magnitude of change tested is determined by an increment variable,
+# which starts at a user-defined value and is halved until it is smaller
+# than 0.1 (an arbitrary value which could easily be changed).
+#
+# For every increment value, all elements are tested with positive and negative
+# changes of this magnitude.  If an element fails to offer any error
+# improvement on a given pass, it is skipped on all future passes for the same
+# increment value.
+#
+# Passes at a given increment value continue until all elements are skipped, at
+# which point the magnitude is halved.
