Study on Scene Extraction Method from Table Tennis Video based on Body Movements

Abstract (in Japanese) (See Japanese page) 
(in English) In this research, we propose a scene extraction method focusing on table tennis competition. Table tennis players set up their fixed camera and shoot their own games. The video taken is used for reviewing own play later, but it has been reported that the time spent playing competitions such as rallies is 20% of the match time. Therefore, the work of reviewing the entire video is not efficient. In this research, we propose a method to extract only the scenes that the user wants to look back from the video. Here, it is assumed that the features of the scenes which should be extracted are body movements. And the scene extraction problem is solved by using a matching method of skeletal time series data based on a hidden Markov model.
