Preprocessing algorithm of hand vein image

Abstract

Characteristics of hand vein can be used in identity recognition. The key to carry out this subject is how to effectively extract the skeleton of the hand vein texture. In this paper, we first process the image of the hand vein by limiting its histogram for contrast enhancement, and use the method of wavelet transformation to denoise the image which has been processed. In the basic texture segmentation of the hand vein we present a separate Niblack adaptive threshold method of image and get a good texture segmentation. © 2013 Springer-Verlag.
