摘要

在视频处理中，对视频压缩有着巨大的需求。视频压缩的基础需要一种称为运动估计的技术。当前块在参考系中的运动估计算法有很多。本文提出了一种用于运动估计的块匹配算法，称为简化三步对数搜索(RTSLS)，该算法在计算效率上比许多现有技术都要高。仿真结果表明，该方法优于三步搜索(TSS)和新三步搜索(NTSS)，并且比TSS减少了近50%的检查点。

Reduced three steps logarithmic search for motion estimation

In video processing there is a huge demand of video compression. The basic of video compression requires a technique known as motion estimation (ME). There are many algorithms to find the motion estimation of current block in reference frame. In this paper we have proposed an algorithm of Block Matching for motion estimation named as Reduced Three Steps Logarithmic Search (RTSLS) which is computationally more efficient than many of the existing techniques. Simulation result shows that it performs better than that of Three Steps Search (TSS), New Three Step Search (NTSS) and reduces the checking points by almost 50% than that of TSS.
