Abstract

As a new biometric technique, finger vein recognition has attracted lots of attentions and efforts from researchers, and achieved some progress in recent years. A survey of progress in finger vein recognition is given in this paper. It mainly focuses on three aspects, i.e., the general introduction of finger vein recognition, a review of the existing research work on image acquisition and feature extraction methods. We finally present the key problems and future directions in order to enlighten finger vein recognition research domain.
