| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a framework to apply the convential method for baseball scene classification into some event-classes (home-run, single-hit, walk, etc.) targeting at only digest videos by learning symbol-sequenced scenes based on the video patternization process to full-game videos, and a method to modify with information about game status in video intervals between events. "Event candidate scenes (ECS)" to be subjected the classification process are segmented based on apperance positions of pitch-view shot, replay scene, inning change and so on. Each ECS is classified into one event-class by the method for event classification based on learning patternized and symbol-sequenced scenes. Event scenes with no events (not-event scenes) are specified on the basis of relations between classification results for ECSs and their time length. We pick out information about game status from not-event scenes and removed intervals in ECS segmentation process by some ways including the detection of base region on the basis of image analysis, and event classfication results can be modified on some constraint conditions estabished by the game status. The proposed method is evaluated by an experiment using some Major League Baseball video games. |
