摘　　要：提出了一种基于灰度直方图的场景转换检测算法,可以由灰度直方图的变化判断是否发生了场景转换。灰度直方图算法有效避免了直方图法的漏检问题和灰度图法的误检问题,同时采用双阈值法提高了检测效率。实验表明,该方法简单有效,且识别准确率较高。In this paper, an algorithm for detecting scene change is proposed. Through the comparison of video grayhistogram, the changes in gray-histogram can he found to determine whether the scene changed. The method can effectively avoid the problems of undeteeting and false drop, and it uses the dual-threshold method to improve the detection efficiency. The experimental results show that this method is simple and effective, and has high accuracy.
