Research Abstract |
In order to extract the distinct difference between the skillful and novice tennis and badminton players form, we have applied the image cognition methodology to the sequential stroke images. The eigen pattern of an image is obtained by projecting the pixel information in x-y screen coordinate to a red, green and blue coordinate systems. The subjects were tournament players and beginners. They worn a white shirts with red, green and blue longitudinal lines. The strokes were done with each subject's best efforts. The motions were filmed by a digital video camera and analyzed by a computer. According to our analysis, the advanced players accelerate the racket toward impact with more prominent upper body twisting than the beginners do. Our proposed approach has a considerable possibility to extract the differences between the skillful and novice tennis and badminton players without any professional human observations.
