Hand gesture recognition using input-output hidden Markov models
Sébastien Marcel, Olivier Bernier, J.E. Viallet, D. Collobert · 2002
A new hand gesture recognition method based on input-output hidden Markov models is presented. This method deals with the dynamic aspects of gestures. Gestures are extracted from a sequence of video images by tracking the skin-color blobs corresponding to the hand into a body-face space centered on the face of the user. Our goal is to recognize two classes of gestures: deictic and symbolic.
