Research on hand gesture recognition based on structure analysis

The paper starts from the model of skin color and the structure of both hands,puts forward a novel gesture segmentation and recognition algorithms.YCbCr model can spilt the color region from complicated background,and extract the gesture to be recognized through multi-zone sign extraction algorithm.Finally,it recognizes gesture in accordance with gesture segmentation and recognition algorithm.The recognition algorithm applied to different environments and different sizes of gesture with better robustness by the test.
