本文提出了一种运动估值算法一预测搜索算法(PSA)。该算法由于利用了运动矢量的空间、时间相关性,可以明显减小搜索范围,提高搜索效率,并能给出正确的运动矢量。文中还对预测搜索算法和全搜索算法(FSM)进行了比较。
This paper presents a motion estimation algorithm - a predictive search algorithm (PSA). Due to the use of spatial and temporal correlation of motion vectors, the algorithm can significantly reduce the search range, improve the search efficiency and give the correct motion vector. The paper also compares the predictive search algorithm with the full search algorithm (FSM).
