AR-KLT based Hand Tracking

This paper proposes a novel real-time robust hand tracking algorithm, integrating multi-cues, and a limb's degree of freedom. For this purpose, we construct a limb model and maintain the model obtained from KLT-AR methods with respect to second-order auto-regression model and Kanade-Lucas-Tomasi (KLT) features, respectively. Furthermore, this method provides directivity of a target, enabling us to predict the next motion. Thus, we can develop a method of hand tracking for gesture and behavior recognition techniques frequently used in conjunction with human-robot interaction (HRI) components. The experimental results show that the proposed method yields a good performance in the intelligent service robots, so called Wever developed in ETRI
