在快匹配运动估计算法中,它的计算复杂度可以描述成:运算量=搜索点×块匹配准则.该表达式可以这样解释,在快匹配准则确定的情况下,如果一个匹配点的单位运算量确定了,这时动动估计的动算量就有直接取于搜索的点数,也就是取决于运动估计的搜索算法，实现了三步搜索法(Match the fast motion estimation algorithm, its computational complexity can be described as: Operational × volume = search block-matching criteria points. The expression can be interpreted in such a way, the fast matching criterion to determine the circumstances, if a match point of the unit operator determine the amount, and then moving moving moving estimate of the volume operator has direct access to the points in the search, that is, depends on the motion estimation search algorithm, to achieve a three-step search method)
