H.264 is the latest video standard recommended by the ITU-T Joint Video Coding Experts Group, in which fractional-pel motion compensation is applied in order to achieve more accurate motion description and higher compression efficiency. However, It remarkably increases the complexity in motion estimation process. In this paper, an efficient fast quarter-pel motion estimation algorithm is proposed.
