There is a music playing with the game; once the music stops, the human and computer show the hand gesture at the same time. The computer can recognize the human’s gesture and then decide who is the winner? The gesture display of the computer is presented randomly and the result of the game will be shown in the computer interface. In the game, the hand gesture recognition is the key part of the system. This system needs a computer and a CCD. First, we separate the hand from the complex background, where the processes of background subtraction and skin color extraction are applied. Next, we use dilation and erosion techniques to delete the noise and compensate the breach. Then let the image be transformed to a binary image. On the binary image, we find the gravity of the hand gesture to be the center of scanning circle. Based on the scanning result, the distance and the angle between the contour and the center can be utilized to recognize the fingers’ number. The proposed algorithm is feasible to recognize the hand gesture with arm or without arm and is workable no matter the hand is shown from any direction.
