The Paper 2 algorithm is complete. It seems good. If I compare Paper 2 (which uses bilateral motion estimation) v/s motion vectors exported by mEstimate filter: $ tiny_psnr 60_source_2.yuv 60_mest-esa+obmc.yuv stddev: 1.43 PSNR: 45.02 MAXDIFF: 174 bytes:476928000/474163200 $ tiny_psnr 60_source_2.yuv 60_paper2_aobmc+cls.yuv stddev: 1.25 PSNR: 46.18 MAXDIFF: 187 bytes:476928000/474163200 Frame comparison: http://www.mediafire.com/?qe7sc4o0s4hgug5 Compared to simple OBMC which over-smooth edges, Objects clustering and Adaptive OBMC makes the edges crisp but also introduce blocking artifacts where MVs are bad (with default search window = 7). But I think it’s ESA’s fault. The paper doesn’t specify which motion estimation method they used; I have been using ESA. I think quality can be further improved with EPZS, which I'm going to implement. I also tried to tweak VS-BMC (Variable size block motion compensation) which reduced the blocking artifacts in VS-BMC area. Had to do experiments a lot, more to be done. mEstimate filter (ESA) + Simple OBMC: http://www.mediafire.com/?3b8j1zj1lsuw979 Paper 2 (full): http://www.mediafire.com/?npbw1iv6tmxwvyu Regards, DSM_ _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
