Efficient heuristic based motion estimation method for video compression

摘要

A heuristic based motion estimation system and method for video compression may include: defining the target block 70; defining a simplified signature block 72; searching the reference frame using the simplified signature block 74; searching for the best match in the area centered around the location of the target block in the reference frame using the simplified signature 76; computing the sum of the absolute pixel-by-pixel difference using motion vectors of the target block's neighbors and a zero motion vector 78; selecting a new block with a motion vector with the minimum sum of the absolute pixel-by-pixel difference 80; and searching adjacent neighbors of the new block for minimum absolute difference match 82.
