This paper presents a far better approach in recognizing the hand gestures supporting curvature of perimeter. Hand gestures are an integral part of communication, especially, if we are communicating any foreign language. Recognition of mitt is a characteristic and natural approach to connect with the PC, where collaborations with the computer can be expanded through various dimensional utilization of hand gestures as contrasted with elective info techniques. The aim of this project is to investigate various techniques for HGR (hand gesture recognition) using detection of the finger tips.This system algorithms makes use of image processing toolboxes of Mat lab, computer vision to access the webcam. The difficult and clumsy interface devices for human-computer interaction (HCI) can be solved by using webcam hand gestures.
