Extract: In order to satisfy the needs of gesture recognization and comprehension in the gesture recognization system, this article put forward a quick detection method of robust fingure and fingure First extracting hte interested gestures according to the clustering character of skin color in color space; then on the former basis,realizing the quick and accurate measurement through the curve rate characteristic method of hand contour edge combined with the ring operator used for detection the parallel The experiment result shows, this method can effectively inspect the fingure and fingure tip in complex situations and will lay the foundation of further applicaiton of gesture recognization
