Interactive Motion Recovery of Chinese Kung-Fu for Computer Games

As a kind of Chinese culture, Chinese Kung-fu has been very popular in movies and TV programs and attracted the interest of people all over the world. The paper address the problem to recover Chinese Kung-fu from video sequence for further use in computer games. Human motion capture for animation and VR has reached a level of capturing real motion data from people using various visual and non-visual sensors. However, most of the available systems require special devices and environment, or even attach extra things onto an actor. To realize a personal system, this paper developed a general software to acquire arbitrary motion from a video sequence. A general 3D articulate human model with changeable size, color and surface shape is prepared. This model is then driven either automatically or manually to match with the moving body in the consecutive image frames. This matching starts from key frames that contain key poses. A specific orientation interpolation is used to get the motion status in in-between frames and finally a smooth motion is obtained. This approach is suitable for personal use to meet wide needs of human motion acquisition.
