摘要
本文通过对直方图法镜头检测的算法分析,给出了一种基于直方图的切变镜头自动检测算法.该算法通过比较视频相邻帧的直方图自动分割视频的切变镜头.实验结果表明,该算法对切变镜头的分割达到了较高的查全率和查准率,算法运算量小,处理速度快.
By comparing Experimental small number An algorithm based on histogram for video cuts detection is presented in this paper. histograms between adjoining video frames, cut shots are segmented automatically. results demonstrate that this algorithm runs fast with high accuracy coupled with a of false positives.
