摘　　要：首先介绍了现有典型切变检测算法,然后提出一种改进的镜头切变检测算法,在字符串匹配算法的基础上用直方图法来进行二次检测.实验显示,这种方法解决了单独用字符串匹配算法造成的误检问题,取得了较好的镜头切变检测效果.In this paper, some typical switching detection algorithms are introduced and then an improved algorithm for detecting video switching is proposed by combining string matching and histogram-based method. The experiments show that this method can solve the problem of the false detection rate caused by using only string matching method, thereby achieving better results of lens switching detection.
