Abstract

Three dimensional(3D) palmprint recognition is a prospective biometric recognition technology, and texture direction is one of its main features. Firstly, the texture direction extracted by the Shape Index(SI) is susceptible to noise interference, and to solve this problem, the noise is eliminated by convolution operation, meanwhile the texture direction is extracted using competitive coding. Secondly, the traditional Surface Type(ST) tends to ignore the small curvature feature information, while the palmprint adjacent points have the same curvature, so a Continuous Surface Type(CST) is proposed to obtain surface consistency. Finally, the method of Collaborative Representation(CR) is used to combine features to complete palmprint recognition in classification recognition. The results of the experiment on the 3D palmprint library of the Hong Kong Polytechnic University show that the average recognition rate obtained can reach 99.92%, and the average recognition time is 0.032s compared with other classification methods. The proposed method can improve the recognition accuracy of 3D palmprint while maintaining low recognition time, and the feature extraction ability and classification recognition effect are of practical value.
