Abstract
This paper studies a method of automatic database creation and effective summary display, of vaulting horse class. The study aims at establishing content creation method which can provide practical functions such as content-based retrieval and summarization. The system records the scenes of vaulting actions in the class using the camera fixed beside the vaulting horse. Then it automatically extracts each jumping behavior, put indices on key actions, and register them onto the database. Indexing on key actions is done, by analyzing spatial relations and their temporal transitions between feature points of the student's circumscribed rectangle and those of vaulting horse model. Experimental results show that the database registration of student ID according to the predefined recording order enables easy access and display of well-performed actions and of specific vaulting actions for comparison. They also indicate that the summarized display of key action's thumbnails promotes visual and objective understanding and confirmation of individual jumping forms and other key points for better performance.
