Method for Real-time Punch Type Recognition by Motion-trace Vecotrization
Huajun Liu · Journal of Chinese Computer Systems · 2008
This paper proposes a method for real-time segmentation and recognition of typical types of punches from continuous captured boxing sequences. Real-time motion data is real-timely provided by a 7-camera Eagle motion capture system. Then segmented punches of variable length are vectorized and uniformly represented. These uniformly represented punches are used to train a LDA based punch type recognizer.Recognition accuracy of the proposed method is 98%.A prototype system for real-time online punch type recognition is implemented in this paper.
