The prediction error can be decreased, incorporating with high accuracy estimation and compensation, and the quality of compressed video can be improved. A fast algorithm of fractional pixel accuracy video motion estimation was proposed in this paper. After half-pel accuracy motion estimation, high accuracy motion estimation can be calculated directly with the intermediate results. According to this fast algorithm, arbitrary fractional pixel accuracy motion estimation can be obtained.
