Review on finger vein feature extraction methods

Abstract

In today's era, personal information security is major topic of concern. In this regard many advanced techniques are used but still in all of those biometric is most reliable. Biometric technologies are based on individual's biological and behavioural characteristics. These system includes human finger, vein, iris, hand and many other as its identifiers. Biometric system using finger-vein as one of its trait is most widely accepted. This paper reviews the various method of feature extraction in finger vein recognition. Most of the existing work is functionally described and compared in three parts i.e., Finger vein image acquisition, pre-processing and feature extraction.
