Hierarchical Recognition of Dynamic Hand Gestures for Telerobotic Application

Abstract

In this paper a scheme is presented for recognizing hand gestures using the output of a hand tracker which tracks a rectangular window bounding the hand region. A hierarchical scheme for dynamic hand gesture recognition is proposed based on the dominant feature trajectories using an a priori knowledge of the way in which each gesture is performed. A state representation is obtained from the dominant feature trajectories, where the states correspond to perceptually important segments of hand movement characterizing the gesture.
