It is an image processing based project. MATLAB was used to process the live video and Arduino controller was used to control the human hand small replica. This model had five fingers same as that of human hand and bent in the same way as that of human fingers. Every change in the movement of human finger in front of the camera is replicated in the mechanical hand model. This project interfaced MATLAB with controller. MATLAB processed real time hand movement and simultaneously sends command to the controller.
