Shot type classification by dominant color for sports video segmentation and summarization

This paper introduces a novel generic framework for sports video processing by using the common feature of most sports: the dominant color of the field. This dominant field color is automatically detected and updated to compensate for the lighting and weather changes by a robust dominant color region detection algorithm. We also introduce new shot type classification algorithms for soccer and basketball. Finally, we use shot-based low-level features for domain-specific high-level applications. Specifically, the system detects soccer goals and summarizes soccer games in real-time, and it enables basketball fans to skip fouls, free throws, and time-out events by segmenting a basketball game into plays and breaks.
