| Abstract: | In recent years,the vein recognition has opened up biometric technology′s new eras.The optical image quality of finger vein acquisition and the accuracy of vein pattern extraction are key issues.In this paper,a novel optical illuminating/detecting method is proposed for the near infrared finger vein image acquisition system,and a finger vein pattern extraction method based on the maximum curvature mechanism is realized.The effectiveness of the whole system is experimentally verified.The experimental results show that the FAR is 1.67%. |
