任意窗运动估值算法

Estimation algorithm using random searching window

提出一种任意搜索窗定位方法，分析和讨论了基于该定位方法下的任意窗全域搜索法（RFS）和三步交叉搜索法（RTCS）。实验结果表明：RFS比FS节约近一半时间，RTCS比TSS运算时间有所节约，几种方法的图像质量相差不大，不同搜索窗下RTCS与FS的图像质量差别亦不大。

In this paper， a method of locating the random search window is proposed． Based on this method， Full Search Method for search window with Random size （RFS） and Three step Cross Search algorithm （RTCS） are analyzed and discussed in detail． The experiment showed that RFS can save approximately half of time used by FS； RTCS also can save a little time used by TSS． There is little difference in the qualities of images produced by these methods．
