Summary:Biometric identification is an important security application and it requires non-intrusive capture and real-time processing. Recently, vein recognition appears to be making real headway in the market, and is considered as the more 'novel' biometric, which is called 'the Fourth Biometric'. This article puts forward a performed solution of a near infrared radiation finger vein imaging processing for vein recognition system. The position-gray-profile (PGP) curve is proposed to analyze the NIR image of vein through the observing. After the stage of the preprocess of the finger vein image, the curvature of the positiongray-profile curve is calculated to extract the vein pattern. In order to test performance of the method, Hausdorff distance is used. Preliminary testing on a database which contains 378 different finger vein images has been carried out and all the images are correctly recognized.
