good vectors? how can i improve them? since it search for every possible place, it should give best match. can you give more details, why surrounding vectors need to be considered? also i tried to compare it with export_mvs, they seems quite similar. the export_mvs ones, sometimes use multiple

Re: [FFmpeg-devel] [Patch][GSoC] Motion Estimation filter

hi here's the new patch. changes: fixed bugs, added documentation added a step option, by default, while searching for macro-block, it moves by 1 px in search area. this can be increased now. uses absolute values instead of squares. vector starts from center of macro-block, before it was at

[FFmpeg-devel] [Patch][GSoC] Motion Estimation filter

Qualification task for Motion interpolation project. here is basic motion estimation filter which uses block matching technique, does full search in (default) 7 px region by 1px step. Thanks, DSM_ 0001-added-motion-estimattion-filter.patch Description: Binary data
