Summarization of MPEG Compressed Video Sequences
Abstract:Video summarization is a fundamental process in video content management systems and aims providing video abstract for navigation and browsing the original video. In this paper, we describe a novel video summarization technique that works in the compressed domain, in particular MPEG videos. Our system first divides a video sequence into shots by detecting abrupt and gradual scene changes using DC histogram differences, then extracts key frames to generate a video summary using hierarchical agglomerative clustering. A set of predefined specifications are set to filter out some clusters and to determine a representative key frame from each shot.
