Robust Commercial Retrieval in Video Streams
TV commercial video is a kind of informative medium. To fast and robustly index and retrieve commercial videos is of interest to commercial monitor, copyright protection, and commercial management, we propose a coarse-to-fine scheme to robustly retrieve commercial videos. Different from previous work using clip or key frames-based matching, our scheme has incorporated the commercial production knowledge to search the candidate commercial positions. Color and ordinal features are extracted for locating the exact commercial positions with dynamic time warping distance. Comparison experiments were carried out over TRECVID 2006 news videos and some videos from Chinese channels. Our scheme has achieved promising simulation results.
