MPEG-4 is a most important international standard for multimedia data compression coding nowadays. The paper describes the topic motion estimation algorithms in MPEG-4, focusing on a motion estimation method based on optical flow field algorithm, and provides detailed theoretical derivation. Through performing approximate evaluation for velocity field of motion images by optical flow field, the time correlation between adjacent frames is rather removed and the fast processing speed is achieved. In addition, the simulation test also proves the feasibility and validity of this method.
