Maintain support for old transformation file versions, however. 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 Add version information to transformation files and update the version from 0 to 2. add version information to transformation files and update the version from 0 to 2 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. 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 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. 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 Support enhancement of high frequencies even when the scale factor is 1.0. support enhancement of high frequencies even when the scale factor is 1 0 Modify the high-frequency filter algorithm to support filtering near the border of an image. modify the high frequency filter algorithm to support filtering near the border of an image 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. 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 Don't filter high frequencies if we're not enhancing them. This improves efficiency, but should not affect output. don t filter high frequencies if we re not enhancing them this improves efficiency but should not affect output Output average match statistic. output average match statistic Update informational output to transformation files to include original frame. update informational output to transformation files to include original frame Add support for post-enhancement of high-frequency details. add support for post enhancement of high frequency details Add support for loading and saving transformation data. add support for loading and saving transformation data Add an option to set the upper bound on correction steps. add an option to set the upper bound on correction steps Modify Makefile to compile with size optimization, since this appears to improve speed characteristics in some cases. modify makefile to compile with size optimization since this appears to improve speed characteristics in some cases Move transformation data structure and related functions to a separate header file. move transformation data structure and related functions to a separate header file 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 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 Add optional support for .jpg, .png, .tiff, and other file formats through ImageMagick. Translation using ImageMagick was suggested by Nick Rusnov. add optional support for jpg png tiff and other file formats through imagemagick translation using imagemagick was suggested by nick rusnov Don't segfault if a file can't be opened. don t segfault if a file can t be opened Use reduced levels of detail in coarser alignment steps to increase speed. use reduced levels of detail in coarser alignment steps to increase speed 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). change perturbation step lower bound check from less than lt to less than or equal to lt change default lower bound to 125 from 1 the behavior is the same but the value makes more sense Change perturbation initial value to 32 pixels from 16 pixels, since coarse alignment is now less expensive. change perturbation initial value to 32 pixels from 16 pixels since coarse alignment is now less expensive Modify scale function so that the borders aren't corrupted (too badly). modify scale function so that the borders aren t corrupted too badly Add support for correction of rotation about the lens axis. add support for correction of rotation about the lens axis Add an optional match criterion for merging. add an optional match criterion for merging Add an option to adjust minimum step-size. add an option to adjust minimum step size Add flags to specify which channels to use for alignment. Use a summation of all channels by default. add flags to specify which channels to use for alignment use a summation of all channels by default Add an option to modify the error metric exponent, and change the default value from 1 to 2. add an option to modify the error metric exponent and change the default value from 1 to 2 Display information about how well a new image matches the accumulated image. display information about how well a new image matches the accumulated image Add a rule for ale.exe to the Makefile. add a rule for ale exe to the makefile Initial release. initial release
