英文摘要	In monocular environment, a method to extract the structure feature points was proposed to improve the accuracy of gesture features detection, and then the extracted structure feature points was used to build and optimize the hand gesture model to extract the high level features. The gradient map was analyzed to give the definition of the smoothing points, no-smoothing points, as well as the conflict calculation method and the structure feature extraction method, to give the proper description of the local structure of the image. 2D (two dimension) gesture model was built to replace the 3D (three dimension) model. Based on the extracted structure feature point, combining the greedy algorithm and RANSAC algorithm, the optimized solution of the model was obtained to locate the palm, fingers and fingertip position. Experiments show that the method has good robustness even when the hand gesture processing result is rough, and it is not sensitive to the segmented edge, so it can effectively reduce the misjudgment caused by the interference point of traditional curvature algorithm. © 2015, Huazhong University of Science and Technology.
