996c81ef01 Specialize the FilterValid routine to not consider the pixels as pixels but rather as values. This seems somewhat inelegant but it's fine in terms of a quick fix. 2013-10-12 16:32:09 -04:00

68f2f4a8b3 If the intensity is greater than one, then we're treating it as a float value, so when packing it into a pixel, just pack the value instead of scaling it to 255... 2013-10-11 21:38:28 -04:00

855683983c SSIM measurement is usually the smallest SSIm index, so report that instead of MSSIM, but if the user wants SSIM we can do that, too. 2013-10-11 13:06:29 -04:00
