Through testing many different Block Matching Algorithms in the motion estimation, the New Three Step Search Algorithm is chosen, which can fulfill the requirement of the system.

在运动估计中通过对多种块匹配算法进行实验，选择了一种可以满足系统要求的算法——新的三步搜索法。

Many fast block-based motion estimation algorithms have been proposed to reduce the computational complexity, for examples, three-step search, four-step search, new three-step search, etc.

于是人们提出了许多快速搜索算法，包括三步法、新三步法和四步法等，这些算法在满足一定精度的条件下可以大大减少运算量。

The three-step search method is a commonly used fast motion estimation algorithm, but its initial step length is too big, thus the estimation effect of slow motion sequence is not so satisfactory.

三步搜索法是一种常用的快速运动估计算法，但由于它的初始步长太大而导致对缓慢运动序列的估计效果不能令人满意。
