Abstract

Abstract: Firstly, this paper presents a method of the dorsal hand vein pattern recognition based on ridgelet transform according to the structure and features of human hand vein patterns images. Secondly, a neural network with local interconnection structure described for its application to extracting the features of hand vein patterns images in order to improve the recognition ability of this biometric system for the unclear image. The experimental data show that this method has more perfect results. 

Key words: biometrics, vein pattern, pattern recognition, ridgelet
