摘要
块匹配法算法是数字电视 (DigitalTelevision ,简称DTV)最常用的运动估值算法。运动估值算法的研究方向是最快、最准确地找到运动物体的运动矢量 ,达到既提高编码效率 ,又能满足电视的实时性要求。通过计算机模拟对块匹配法的几种搜索法进行了比较研究 。
Block matching Algorithm is the most common used digital television (DTV) moving evaluation Algorithm. How to find the moving vector of moving object. Quickly and accurately, which can both enhance improve encoding efficiency and satisfy the requirement of TV's real time is the study tendency direction of moving evaluation Algorithm. Several block matching. Algorithm is compared by compute simulation in the paper. Some useful conclusion has been drawn out.
