Key frame extraction algorithm under compressed domain based on two detection curvature
基于两次检测曲线的压缩视频关键帧提取*

The traditional key frame extraction algorithms under compressed domain have the problems that the selected feature is single,the accuracy of the extracted key frames is low,and the efficiency of the algorithms' performance is not high.This paper proposed a key frame extraction algorithm under the compressed domain based on curvature detection.The proposed algorithm denoted the significant changes of the curve using high curvature points on the curve.Then,it constructed the feature similarity curve by using...
