چکیده

Owing to convenience and naturalness, hand gesture recognition has been widely used in various human-computer interaction (HCI) systems. In this paper, we address the problem from the perspective of system, and present a static hand gesture recognition algorithm based on Krawtchouk moments. The effect of the order and number of Krawtchouk moments on the recognition performance is studied in detail. In the experiments, 15 popular gesture signs are used to verify the effectiveness of the presented hand gesture recognition system. Experimental results demonstrate that lower order Krawtchouk moments are more suitable for classification. Furthermore, the number of Krawtchouk moments also has a significant impact on the recognition accuracy.

Applying mean shift and motion detection approaches to hand tracking in sign language

Hand gesture recognition is very important to communicate in sign language. In this paper, an effective object tracking and hand gesture recognition method is proposed. This method is combination of two well-known approaches, the mean shift and the motion detection algorithm. The mean shift algorithm can track objects based on the color, then when hand passes the face occlusion happens. Several...
