Fast scene change detection for personal video recorder
Jung-Rim Kim, Sungjoo Suh, Sanghoon Sull · IEEE Transactions on Consumer Electronics · 2003
We propose an efficient scene change detection method for personal video recorder to provide users with several convenient functionalities such as the browsing, fast forward and skip-play of recorded videos. Since most of the current available PVRs have low-powered CPUs, the scene change detector should not be computationally expensive. We implement the scene change detection algorithm using reduced images of only intra pictures in MPEG-2 compressed domain. The experimental results with a commercial PVR demonstrate the efficiency of the proposed method.
