Skill Level Evaluation of Motion Curved Surface Character

The skill teaching/succession method is not quantitative but qualitative, which is abstract oral or gesture expression. Quantitative teaching is difficult for teacher/instructor. In previous research, Expert and beginner perform the sports and entertainment motion, and the character of the motion curved surface is analysed using Microsoft Kinect (RGBD camera). The character is the maximum curvature and surface area. However, the usage of characters is uncertain. In this research, we investigate the correlation of maximum curvature and surface area from motion curved surface in before and after training. Therefore, we visualize the different correlation of experts and beginners from the characters and the transition of the skill training.
