Replay detection in broadcasting sports video

An effective replay detection method for broadcasting sports videos is proposed in this paper. The algorithm is composed of logos detection and replay recognition. Firstly, a logo-template is automatically extracted from logo-transition at the beginning of a video. It is further used to detect the other logos in the same video. Then, with taking logos as boundaries, the video can be divided into replay and non-replay segments. To identify replay segments, an SVM classifier with mid-level features is utilized. Experiments demonstrate the effectiveness of this method.
