Abstract

A convenient video browsing system for popular sports such as baseball, tennis and billiards is proposed in this work. A sports video is automatically segmented into video clips and annotated with semantic concepts in terms of event type. For sports with specific game structure, e.g. baseball and tennis, we further analyze the entire video of the match with the aid of caption information, webcast information, and the domain knowledge of the corresponding sport. Each segmented video clip with semantic annotation is then mapped to a certain part of the game structure. Finally, the proposed system, name as Sports Wizard, provides a favorable way for the user to browse sports videos based on semantic concepts or game structure.
