Motion Detection Method for Video Feedback System to Assist Karate Training
Abstract: When sports coaches induce their trainees to acquire motion skills, higher performance can be obtained if images of photographs of movements of the trainees themselves are presented for their observation. It is known as video feedback. However, video feedback is not used routinely at ordinary sports practice sites. The main hindrance blocking the wider utilization of video feedback is that “it is troublesome to detect an objective scene from video image files”. The purpose of this study is to develop a video feedback system for sport skill training based on automatic video image retrieval. The study has focused on karate training and developed a karate offensive motion detection method. The paper describes the video feedback system and the motion detection method.
