一种针对MPEG-4 AVC/JVT/H.264的快速多帧运动估计算法

在H．264标准中，运动估计的编码运算量非常复杂。通过重新使用上一参考帧中的运动矢量信息，论文提出了一种效率较高的搜索算法，即无需在全部的参考帧中搜索，只使用存储的运动矢量来组成当前的运动矢量。这种算法还可以结合其他快速的搜寻算法以进一步减少运动估计的运算复杂度。

Rapid Multi- frame Motion Estimation Algorithms for MPEG- 4 AVC/JVT/H.264

In H.264 standard,a lot of computational complexity will be consumed in the encoder for motion estimation.Efficient searching algorithms are proposed by reuse of the motion vector information from the last reference frame.The proposed algorithms use the stored motion vectors to compose the current motion vector without performing the full search in each reference frame.Any fast search algorithm can be utilized to further largely reduce the computational load for the motion estimation from previous one frame.
