摘要 提出了一种适用于H .2 6 4的快速运动估计方法 :使用一维映射作为块排除准则 ,并充分利用H .2 6 4中的运动估计模式间的匹配冗余 ,使得 7种运动估计模式并行执行。试验结果表明 ,在估计精度几乎无损的情况下 ,本文算法比传统的全局搜索速度快 A fast algorithm (PFS) applicable to H.264 is proposed: utilizing one dimension projection to eliminate unwanted positions. The algorithm can make 7 modes of motion estimation perform almost simultaneously. The simulation results show that the proposed algorithm is up to 6 times faster than the exhaustive search algorithm, with almost identical performance.
