Abstract

In this paper, we propose an estimation method of a rally scene from a table tennis video for broadcasting. The video is constructed of entry, rally, replay, and break scenes, the scenes are detected by comparison of adjacent frames. The rally scene shows a ping-pong table, and the table is extracted in the detected scene. In addition, an appearance of the rally scene is higher than the others, and the top number group of the scenes is defined as the rally scene. As a result of an evaluation experiment, the estimation accuracy of the proposed method is 96.8 % from 711 rally scenes of ten videos.
