Computer Vision class project (Fall 2004)

The goal of this project was to develop an interface to control a very simple game using hand gestures captured by a regular webcam. The software was implemented in Matlab and the two main image processing techniques are (1) background subtraction, and (2) Fourier shape descriptors. In the begining of the video to the right, the user is asked to especify the hand gestures used to: pause, resume and quit the game; and to fire or navigate the "space ship" on the upper right corner (the small "asteroids" are not visible :-).
