Abstract

Recently, a walkthrough type vein authentication system has been attracting extensive attention, which is effective for wide-scale events such as big event venue, theme park, and so on. In our previous study, a hand waving finger vein authentication system was proposed, in which a similarity between enroll and verification finger vein patterns was calculated based on Normalized Cross Correlation [1] and Scale-Invariant Feature Transform [2]. These methods perform worse in case that the baekground of the captured frame has significant noises such as the bright light sources. In order to eliminate such noises and extract a finger region correctly, we apply a machine learning method. In this study, we employ U-Net [3] as a machine learning method and evaluate it compared to conventional image processing techniques.
