一种快速的自适应镜头边界检测方法

摘要

To reduce amount of video data processing and improve detection efficiency,this paper proposed a rapid method for adaptive shot boundary detection. The method extracted a new video frames sequences from original video frame sequences by frame-skipping method. For the shot boundary detection, used distance values between brightness-differences and their average as detected features in the moving window. The experimental results show that the proposed method can improve detection efficiency significantly and detect shot boundary change effectively.%为减少视频处理数据量及提高检测效率,提出一种快速的自适应镜头检测方法.该方法利用跳帧法从原始视频帧中提取新的视频帧序列,通过计算滑窗内亮度直方图帧差到帧差均值的距离来检测镜头变换.实验结果表明,在显著提高检测效率的同时.该方法能有效检测出镜头变换.
