Abstract

This paper presents a structure tensor to nonlinear diffusion filtering for the infrared multi-band finger vein images to solve the lower contrast and uneven gray distribution in the infrared single band finger vein image. This joint structure tensor makes the nonlinear diffusion along the vein tendency, the structure preserving of vein edge and removing the speckle noise. In the examination, the proposed method shows the enhanced result.
