Real-time Hand Gesture Recognition by Shape Context Based Matching and Cost Matrix

How to recognize the shape gesture for new human-computer interface without controller required and bring entertainment, games industries and information appliances in new ways. In this paper, the authors would illustrate a real-time hand gesture recognition system by using shape context matching and cost matrix. The shape context is taken as a basis description for shape matching. It can be regarded as a global characterization descriptor to represent the distribution of points in a set with scale and rotation invariance. In this paper, they developed a perceptual interface for human-computer-interaction based on real-time hand gesture recognition.
