Abstract:
This paper presents RSViewer, a video browsing system specialized for racquet sports, which reflects users’
interests. Methods to support users in browsing racquet sports matches by summarizing video composed of
important rally shots have been discussed in a previous study. However, the method is not practical enough
because the auditory events should be manually annotated in advance to detect such scenes. Therefore, we
propose an automatic rally shot detection based on shot clustering method using white line detection. Our
system calculates the importance of rally shots based on audio features. As the result, the summarized video
can facilitate users find and review the information they need. The result of experiments shows that our
method is effective in an aspect of efficient video browsing experience. Furthermore, we propose a high-speed
playback method customized to racquet sports video and realize more efficient video browsing experience.
