.A fast quarter-pixel motion estimation algorithm for H.264/AVC[J].Optoelectronics Letters,2008,4(1):66-68 A fast quarter-pixel motion estimation algorithm for H.264/AVC CHEN Gang JIA Zhen-hong CHEN He School of lnformation Science and Engineering, Xinjiang University, Urumqi 830046, China Abstract:       A fast quarter-pixel motion estimation algorithm is proposed in this paper. The proposed algorithm based on mathematical models of the motion compensated prediction errors. Unlike conventional quarter-pixel accurate motion estimation algorithm,proposed algorithm can avoid fractional-pixel interpolation and subsequent fractional-pixel search after integer-precision motion estimation. Experiments show that the proposed algorithm greatly reduces the computational complexity of quarterpixel motion estimation, while keeping the nearly equal quality of the image.
