一种快速的自适应镜头边界检测方法

Rapid method for adaptive shot boundary detection

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。

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.
