Temporal Segmentation of MPEG Video Sequences

The video segmentation is a fundamental tool for the video semantic content evaluation. In multimedia application, videos are often in MPEG-1 format. In this paper, an algorithm for the automatic shot segmentation of MPEG-1 sequences is presented. The adopted method is based on heuristic considerations concerning the characteristics of MPEG-1 video streams. In particular, the pattern structure and the I-, B- and P-frame sizes are taken in account. The proposed algorithm has been applied to MPEG-1 sequences and some results are reported.
