Automatic detection of replay segments in broadcast sports programs by detection of logos in scene transitions

In broadcast sports, replays provide viewers another look at interesting events. We propose an automatic algorithm for replay segment detection by detecting frames containing logos in the special scene transitions that sandwich replays. Detected replays are utilized in efficient navigation, indexing, and summarization of sports programs. The proposed algorithm first automatically determines the logo template from frames surrounding slow motion segments, where slow motion segments are automatically detected using [4]. Then, it locates all the similar frames in the video using the logo template. Finally the algorithm identifies the replay segments by grouping the detected logo frames and slow-motion segments. Our algorithm accurately detects replays, with or without slow motion.
