In real-time video encoding, motion estimation algorithms are required for compression of moving pictures. So development of a fast motion estimation algorithm is the basic need to improve the efficiency of motion estimation in the process of video encoding. A novel Diamond based X-pattern Search (DXS) algorithm has been proposed in this paper. It is based on the center-biased characteristics of the motion vector distribution in videos. Simulation results demonstrate that the proposed algorithm reduces average search points by 6% to 59% according to different motion types with reduced computation time and maintain almost the same visual quality compared to other well known block matching algorithms.
