Description 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. The key idea behind solving the problem is to translate the richness of the human gestural communication power to a machine for a better man-machine interaction. 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. The concept of motion energy is used to estimate the dominant motion from an image sequence. To achieve the desired result, we introduce the concept of modeling the dynamic hand gesture using a finite state machine. The temporal signature is subsequently analyzed by the finite state machine to interpret automatically the performed gesture. (C) 2000 Pattern Recognition Society. . .
