摘要
提出了一种利用图象固有特征的快速运动估计算法．在大多数情况下，图象中运动的变化在图象内和图象间往往是连续的．以相邻宏块（空间或时间上相邻）相应的矢量作为当前矢量的搜索起始矢量，作分级的按渐开顺序的搜索，从而使计算量几乎与运动矢量的实际范围无关，大大减少了计算量，而得到的图象质量没变．
Some characteristics of moving pictures are considered, in which the motion in a picture or among pictures is continuous in most of the cases. The motion vector of adjacent macroblocks (spatial or temporal) is used as the initial searching vector of the current macroblock, to search a multistage in an involute like scanning. It makes the computing complexity independant on the range of motion vectors.
