N2 - In this work, we proposed a shot-change detection algorithm for intra-frames of H.264/AVC compressed video. The traditional video codec, such as MPEG-1, 2, H.261 or H.263, transforms the macroblocks of intraframes into DCT domain, but H.264/AVC video codec requires the intra prediction process prior to DCT processing, therefore DCT coefficients of H.264/AVC represent differently from those of the traditional codec. The past algorithms of shot change detection using DCT coefficients are not suitable for H.264/AVC any more. In this paper, we compare the statistical distribution of intra prediction modes with an adaptive threshold to detect the shot change. Our algorithm also combines the luma with the chroma feature to detect shot change for color video. The experimental result shows our algorithm can achieve accurate detection rate in rapid speed.
