Abstract

This paper presents a novel scene change detection method in H.264/AVC compression domain. We note that, comparing to previous MPEG compression methods, some unique compression schemes such as intra prediction, CAVLC etc. are adopted for H.264/AVC. Therefore, previous scene change detection methods for MPEG-1 or MPEG-2 are not directly applicable to the compressed bit stream of H.264/AVC. To solve this problem, we propose a novel scene change detection algorithm for H.264/AVC, which exploits intra prediction modes of macro block. Since our method requires a simple decoding of the prediction mode, it is quite fast. Also, the precision and recall for various video sequences and bit-rates turn out to be promising.
