Gesture based interaction systems are becoming more and more popular both at workplace and home. The projects intends to develop a system that can recognize hand gestures which can be used as an input command to interact with the PC which can be applied to picture gallery browsing. One of the key areas that needs to be looked at while developing such systems is the image processing stage. Since it would be very hard to produce an algorithm that can recognize gestures in the time allocated, within my project, I plan to design and implement a system that can perform general image processing of the user image captured in real time. Most of my work will be based on image processing techniques. My expected outcome will be an algorithm that can detect skin regions of the image user image captured and detect contours around the detected skin regions. In order to manage my project I will be using Waterfall model as the system development methodology. Microsoft Visual C++ will be used for the implementation of the code developed with combination with the OpenCV library. I feel that if I successfully meet my targets then I will have contributed towards the future of natural gesture based interfaces, if only in a minimal way.
