Multi temporal distance images for shot detection in soccer games

We present a new approach for video shot detection and introduce multi temporal distance images (MTDIs), formed by chisquare based similarity measures that are calculated pairwise within a floating window of video frames. By using MTDI-based boundary detectors, various cuts and transitions in various shapes (dissolves, overlayed effects, fades, and others) can be determined. The algorithm has been developed within the special context of soccer game TV broadcasts, where a particular interest in long view shots is intrinsic. With a correct shot detection rate in camera 1 shots of 98.2% within our representative test data set, our system outperforms competing state-of-the-art systems.
