In this paper, we creatively present a viewpoint-free hand gesture recognition system based on Kinect sensor. Through depth image, we build Point Clouds of user. Then, we estimate the current optimal viewpoint, i.e., the front, and project Point Clouds to that direction. Through that process we in great extent overcome the viewpoint-dependency issue. To match hand types, we propose an improved shape...
In this paper, we present a method of recognizing hand gestures in the form of point clouds recorded by Kinect sensor. Firstly, through Laplacian-based contraction and further processing, we extract skeleton points from point clouds of hands. Then, we apply a novel partition-based descriptor and corresponded algorithm to classify these skeletons and, taking one step further, to recognize gestures...
Of various Human-Computer-Interactions (HCI), hand gesture based HCI might be the most natural and intuitive way to communicate between people and machines, since it closely mimics how human interact with each other. Its intuitiveness and naturalness have spawned many applications in exploring large and complex data, computer games, virtual reality, health care, etc. Although the market for hand gesture...
