英文摘要Replays are key cues for events detection in sport videos since they are the immediate consequence of highlights or important events happened in sports. in many sports videos, replays are usually sandwiched with two identical logo transitions, prompt the beginning and end of a replay. a logo transition is a kind of special digital video effects, usually contains 12-35 consecutive frames, describe a flying or variable object. in this paper, a novel automatic logo detection approach is proposed. it contains two main stages: a logo transition template is automatically learned by dynamic programming and unsupervised clustering, a key frame is also extracted; then the extracted key frame and the learned logo template are used jointly to detect logos in sports videos. the optical flow features are used to depict the motion characteristics of the logo transitions. experiments on different types of sports videos show that the proposed approach can reliably detect logos in sports videos efficiently.
