Abstract: This thesis describes a study on a novel intermediate representation to bridge the gap between low-level features and semantic meanings in soccer video analysis. Based on our study, we conclude that shot is not suitable as a mid-level representation for soccer video parsing. We classify a soccer video into seven categories, and assign each category a word, called semantic descriptor, to indicate its semantic meaning. Therefore, a soccer video can be represented by a semantic descriptor sequence. Two different approaches, segment-based and frame-based approaches, were designed to realize this representation A total of 450 minutes of soccer video from FIFA2002 were used to test the two approaches. The average accuracy is 81.0% for the frame-based method and 76.1% from the segment-based.
