Abstract :
The analysis of a dynamic hand gesture requires processing a spatio-temporal image sequence. The actual length of the sequence varies with each instantiation of the gesture. We propose a novel, vision based system for automatic interpretation of a limited set of dynamic hand gestures. This involves extracting the temporal signature of the hand motion from the performed gesture and is subsequently analyzed by a finite-state machine to automatically interpret the performed gesture
