Abstract
A method and system that recognize a hand gesture using selective illumination that can reliably perform hand gesture recognition by effectively removing an unnecessary image and noise including static disturbance light and dynamic disturbance light are provided. The method of recognizing a hand gesture includes acquiring, by a controller from an imaging device a hand image, which is a recognition target. A static background image and a dynamic background image are removed by the controller from the hand image. The method further includes recognizing, by the controller, a gesture of the hand by extracting a characteristic point from the hand image in which the dynamic background image is removed.
