Slow motion replay detection of tennis video based on color auto-correlogram

摘要

In this paper, an effective slow motion replay detection method for tennis videos which contains logo transition isproposed. This method is based on the theory of color auto-correlogram and achieved by fowllowing steps: First,detectthe candidate logo transition areas from the video frame sequence. Second, generate logo template. Then use colorauto-correlogram for similarity matching between video frames and logo template in the candidate logo transition areas. Finally, select logo frames according to the matching results and locate the borders of slow motion accurately by usingthe brightness change during logo transition process. Experiment shows that, unlike previous approaches, this methodhas a great improvement in border locating accuracy rate, and can be used for other sports videos which have logotransition, too. In addition, as the algorithm only calculate the contents in the central area of the video frames, speed of thealgorithm has been improved greatly.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
