摘要
介绍了一种自适应块匹配新算法,这种算法充分考虑了活动视频序列中运动物体与变化区域的具体情况,结合块的划分与匹配估算,得到了一个合理的迭代运算流程,其特点是在单机环境下同时进行一批块的匹配与处理。最后采用这个算法对部分活动视频序列进行了仿真计算,取得了部分结果,经分析表明,这种算法对于运动复杂度较大的视频活动信号具有更好的性能。
A new algorithm of adaptive block matching is introduced.In this new algorithm the detail cases of moving objects and changed frames are considered more fully.Combined with the blocks distributing and matching methods,a rational iteration computing flow has been obtained.Its new point is that matching and processing of several blocks are doing at same time in single PC.Finally,a several simulated computations for some active video serials are made using this new algorithm and some results are obtained. The analysis of these results shows that the algorithm has more high properties in high moving complexity video signals.
