A method for hand gesture recognition based on morphology and Fingertip-Angle

This paper proposes an automatic method to recognize the hand in complex background. With this method, contour of hand in pictures can be figured out and the fingertips can be marked out. Skin color detection is used to find out the hand region out of a complex background, then a serial of morphological operations is performed to get the contour of the hand, and the computation of Fingertip-Angle is for marking out the fingertips. The simulation result shows that out method has a good performance for images with low computation cost.
