Anisotropic Diffusion Filter for Dorsal Hand Vein Features Extraction

Abstract: In this paper, we present an competent approach for dorsal hand vein features extraction from near infrared images. The physiological features characterize the dorsal venous network of the hand. These networks are single to each individual and can be used as a biometric system for person identification/authentication. An active near infrared method is used for image acquisition. The proposed approach uses an anisotropic diffusion technique for contrast enhancement and morphological filtering to extract the venous network.
