An image processing method based on color filtering was proposed to realize hand tracking in a virtual reality system. Based on computer vision techniques, the method simulates the exclusive property of color vision of human eyes. Using the color of hand as a reference, the image received by CCD is processed to eliminate the images of the background and other objects. After smoothing and contour extraction, only the profile of the hand is left in the image. The method can eliminate the disturbance of the background and other objects. It can improve the reliability and increase the speed of hand recognition.
