- Abstract:
-
A novel algorithm based on the spatial pyramid bag of features is proposed to describe the hand image. It is proposed in order to solve the problem that the distribution of feature points cannot be ascertained when using the hand gesture descriptor based on bag of feature of scale invariant feature transform (BoF-SIFT). The capability of the BoF-SIFT can be improved by generating image spatial pyramid. The descriptor can effectively represent the posture by combining the global features and local features of the gesture image, as well as the distribution character of image feature points. Finally, the hand posture recognition is achieved by using the histogram intersection kernel support vector machine (SVM). The experiment on standard database demonstrates the average recognition rate can reach 92.92% for 10 kinds of gestures recognition, verifying the efficiency and effectiveness of the proposed algorithm.
