| 摘 要： | 通过分析MPEG视频流中I帧的8×8DCT编码块的DC系数的统计特征,用每个88 DCT编码块的DC系数计算I帧图象的亮度、行列直方图,比较I帧之间直方图的差异,直接从原始的MPEG视频流中侦测镜头切换点.

| Abstract: | By analysing statistical features of DC coefficient,computing intensity,row,and column histograms that are computed using DC coefficient of each 88 DCT encoded block in I frame,comparing the intensity,row,and column histograms of I frames,the transition point between two shots can be directly detected from raw MPEG video stream. |
