Design and Implementation of a Hand Gesture Based Digital Lock Demonstrator

The security is a vital apprehension. An omnipresent part of all security systems is a key protected admittance control. It allows only the authorized people to enter into a restricted zone. This paper focuses on designing and implementing hand gesture recognition based digital lock system. The objective is to design a functional lock system using Human-Computer Interaction (HCI) with display for theeducation purpose. Keeping in mind the demonstration purpose, the system modules are kept easily accessible. The solution is based on a web camera, which is used as the main component to captures a live-stream video with the help of a specifically designed algorithm in the MATLAB. The system is able to identify the hand-gesture. This algorithm is designed to enhance a specific frame from the video to get better results. Later, this frame is converted into a binary image so it can be easily subtracted from a background image that has been provided in the database. A system prototype is implemented and its functionality is tested. The results are presented.
