摘　　要：改进了分层变尺寸块匹配运动预测时域滤波算法,将其逐点进行的分数像素寻址与滤波改为了按匹配块进行寻址与滤波,这样就将对每一个像素执行一次的操作简化为对不同大小的匹配块统一进行一次操作,大大节约了运算开销,实验结果表明新算法相比原算法运算速度提高了5倍左右。The algorithm of hierarchical variable size block matching motion compensation temporal filtering was improved. Its one-byone sub - pixel addressing and filtering was replaced by the matching block addressing and filtering. So the operation on each individual pixel was predigested to a uniform operation on various sizes of block and saved a lot of operation spending. The experiment results show the speed of the new algorithm is about five times larger than the original.
