Enhancement of Finger Vein Patterns Extracted by Maximum Curvature Method

Finger vein patterns have been proposed as a suitable biometric feature for authentication applications. Systems using this feature are generally low cost, accurate and easy to use. Our goal in this paper is to improve the efficiency of vinous extraction. For robust and precise extraction of the depicted veins, a method of calculating local maximum curvatures in cross-sectional profiles of a vein image was used. The results obtained from image quality assessment were promising.
