Abstract
The present invention discloses a system and method for performing motion estimation associated with an encoder, e.g., a H.264/MPEG-4 AVC compliant encoder. For example, the method selects a motion vector centering for a current block in a search area of at least one reference picture. The method calculates a matching cost for each of a plurality of candidate motion vectors derived from the search area, and outputs at least one of the plurality of candidate motion vectors based on the matching cost associated with each of the plurality of candidate motion vectors to a main coding loop.
