three-step search method 三步搜索法
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。
Using the criterion of "minimum bending strain energy", the optimum hoisting points of the column are determined with the method of "three step cycling coordinate search".
以“弯曲应变能最小”为优化准则、采用“三步循环坐标搜索法”求解最优吊点坐标。
Motion compensated gain and entropy of motion vector can be improved evidently, but the number of search is less then that of three step method.
达到比三步法还要少的搜索次数，运动补偿增益和运动矢量熵均比三步法有明显改善。
