Abstract

Video processing has found many applications in sports such as slow motion replay, pattern analysis, statistics collection, video archiving, etc. This paper presents an automatic archiving system for tennis games. It extracts ball trajectory using calibrated cameras. The trajectory is then used to classify tennis video clips into 58 tactic patterns. Semantic annotation is then attached to each clip so future query can be made easily. The annotated video clips can be used for training, sports analysis, broadcasting, etc. It can also be used for online browsing and streaming.
