Abstract

Finger vein biometric is a novel technology for personal identification, and acquisition of finger vein image is difficult in finger vein recognition. In this paper, scattering and absorption characteristics of skin, muscle, phalanx and vein of finger under near infrared light are analyzed, and the mathematical model about imaging process of finger vein is established. Then on this basis, the relation between light source wavelength and image quality is investigated, and images quality under two single wavelengths including 850nm and 940nm are analyzed by use of image contrast. Experimental results show that the mathematical model is available to imaging process of finger vein.
