Block motion estimation using full search is computationally intensive, many fast algorithm have proposed to reduce the computation at the expense of less accuracy of motion estimation. in this paper, we present a new fast and efficient search algorithm for block motion estimation. the proposed algorithm is based on the ideas of predicted starting search point, subsampled block distortion measure, center - biased distribution of motion vector, multiple - candidate diamond search. from the experimental results, the proposed algorithm is superior to many other well - known fast algorithms in both quality performance and computational complexity
演算法採用多步搜索方法，利用相鄰塊之間的運動相關性，選擇反映當前塊運動趨勢的預測點作為初始搜索點用子采樣塊匹配失真度量來減少計算量利用運動矢量的中心傾向的分佈特性，用多侯選點鉆石形狀搜索方法來提高運動估計的速度和準確性。
