| 摘 要： | 研究并设计了一种以互相关分析为基础的视频镜头边界检测系统,该系统以分析前后相邻帧中若干条线段的灰度分布曲线相似度为基础,并结合了图像灰度直方图的相似度分析,比较有效地解决了镜头中有闪光灯出现和镜头快速移动时易出现的误检等问题,同时,克服了新闻节目中主持人画面渐变切换引起的漏检问题.该系统计算量小,可满足实时性分析的要求.

| Abstract: | A system of shot boundary detection based on the correlation-analyzing algorithm is designed in this paper. The system which is based on analyzing the resemblance extent of gray distributing curve of two pictures border upon in video stream combines the correlation analysis of histogram of pictures and has solved the problem of wrong identification caused by common arithmetic when there is flashlight and motion of the shot. In addition, it has solved the problem of failure detection caused by gradual change of compere pictures in news programs. The system has low computation cost and meets the demands of real time analysis. |
