摘要
针对多媒体处理时运动估计引起的巨大计算量的问题,提出了一种简化的运动估计方法,当更新搜索窗口的数据时,仅更新搜索窗口移动后发生变化的一列宏块数据,从而减少更新量,提高多媒体处理的运算性能。
In order to save the huge computational costs caused by motion estimation in multimedia processing,a reduced motion estimation method is proposed.Updating the data in current searching window,only the row of macroblock which has changed should be updated.So,the computational cost reducing significantly.The performance of multimedia processing is hence improved.
