Looks like I need to improve the commit message, will update in the V2. :) In fact, when I try to use nlmeans for denoising a 1080P size pictures, I found nlmeans is really SO slow, then I profiling the code, found nlmeans_slice is the bottleneck, this is the to remove the pdiff_lut_scale when search the exp() table in nlmeans_slice function. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
