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