Finger vein pattern recognition is a biometric modality that uses features found in the blood vessel structure of the fingers. Vein pattern images are captured using a specialized infrared sensitive sensor which due to physical properties of the hemoglobin present in the blood stream give rise to a slight intensity difference between veins and tissue. We investigate five different contrast enhancement algorithms, which range from high to low computational complexity, and evaluate the… CONTINUE READING
