Abstract

Temporal segmentation of video in the compressed domain is becoming increasingly popular due to its computational advantages over video decompression followed by pixel-domain segmentation. This paper discusses the advantages of compressed-domain processing, and proposes a computationally-efficient method of detecting scene changes without reconstructing the video. The target application provides requirements that allow the algorithm to avoid complicated processing that searches for unnatural scenes changes such as dissolves, fades, and wipes that are common studio effects. The paper provides experimental results to demonstrate operation of the algorithm on real data.
