Tennis video enrichment with content layer separation and real-time rendering in sprite plane

Sport video enrichment can provide viewers more interaction and user experiences. In this paper, with tennis sport video as an example, two techniques are proposed for video enrichment: content layer separation and real-time rendering. The video content is decomposed into different layers, like field, players and ball, and the enriched video is rendered by re-integrated these layers information. They are both executed in sprite plane to avoid complex 3D model construction and rendering. Experiments shows that it can generate nature and seamless edited video by viewerspsila requests, and the real-time processing speed of 30 720times480 frames per second can be achieved on a 3 GHz CPU.
