At initial stage, hand detection algorithm has been applied to detect the hand using machine learning approach. Later, the methods of contour detection and convex hull are considered for gesture recognition. The system has been trained with variety of gestures and hands with different hand positions. © INDIACom-2017.Contour detectionConvex hullGuesture recognitionHand detectionKernel functionsViola-Jones framework
