ABSTRACT:
A method and apparatus for determining the quality of a block match for a candidate motion vector in a video encoder system using motion vectors representing the difference in coordinates of a macroblock of data in a current frame of video data and coordinates of a related macroblock of data in a reference frame of video data. The method can include defining a search pattern, searching a region based on the search pattern for a candidate motion vector for evaluation, calculating a difference metric, calculating a bias based on the difference between a predictor motion vector and a candidate motion vector, determining a modified difference metric by adding the difference metric to the bias, and defining a final motion vector based on the modified difference metric.
