摘　　要：提出一种基于对象的快速自适应的混合运动估计方法,利用同一对象的运动矢量之间的相关性,根据搜索过程中块匹配的程度,减小或增大搜索范围。实验表明,该算法既降低计算量,又保持了较好的图像质量。In the article,we propose an object based fast,self-adaptive,mixed search motion estimation algorithm.Due to relativity between motion vectors,according to the degree of block matching,the search range can be reduced or increase d.The experiment results reveal that the algorithm is better,and it is computationlly efficient and keeps better image quality as well.

关 键 词：运动估计 对象 快速自适应 混合搜索 图像编码
