Abstract
A computationally efficient method and apparatus for motion estimation by producing accurate motion vectors with minimal computational effort. A preferred embodiment of the present invention first identifies an approximate match between a reference frame and a current frame of video data. Once an approximate match is found, the method performs at least two searches at a finer pixel level, until a motion estimate is reached.
