基于运动矢量时-空特性的快速运动估计算法研究
Fast motion estimation based on the special and temporal characteristic
摘要
Abstract
The spacial and temporal character of motion vector were analysed and according to the spacial and temporal characteristic of motion vector, the different proposed search schemes were adopted for motion estimation; The experi-mental results shows the proposed algorithm reduce the prediction error and has a significant computational speedup compared with other algorithms, but offers a similar, even better performance.关键词
