DETECTION AND TRACKING OF MOVING HANDS USING VARIATIONAL METHODS AND PARTIAL DIFFERENTIAL EQUATIONS

Detection and tracking has been an important area of research in computer vision and is central to many NASA applications. The detection and tracking approach discussed will be applicable to the Virtual GloveboX (VGX) project which is an on going research project in NASA.VGX is an advanced simulation system for astronauts to perform precise biological experiments in a glovebox abroad the international space station. The present design of the VGX utilizes technologies that currently incorporate electro-mechanical sensing gloves and force feedback devices, which has inherit limitations in terms of maintaining the naturalness of user interaction with the simulator. This problem could be overcome by using non contact computer vision based detection and tracking system for effective and efficient human-computer interaction in virtual environments. The tracking need not be restricted in 2D but also be extended to 3D.
