PALM VEIN RECOGNITION

Biometrics is automated methods of recognizing an individual based on a physiological or behavioral characteristic. Biometric system consists of two subsystems; one for enrollment and the second is for recognition. In enrollment, used three biometric samples used to create user’s main template. While, in the recognition phase, the system tries to identify who is the person (in the case of identification) or to verify is the person who claimed to be (in the case of verification).In recent years, when normal fingerprints have failed in some skin conditions, research has turned towards veins and iris where results are
guaranteed used for the identification/verification of individuals. The vein trace is hard to damaged, changed or forge since veins are immersed inside the human body.In this thesis, a biometric system was developed for Palm Vein Recognition (PVR), the palm vein image is firstly preprocessed to simplify the task of isolating the vein from the background, apply region of interest extraction (ROI) to use only this useful and interest rectangle that using in the next steps. Then the image is enhanced to prepare it for segmentation process, in which separation of the vein pattern from the background that used for recognition to certain low percentage of errors. The final stage is the feature extraction the image is traced and divide it by blocks. For each block,Mean and standard deviation are extracted once depends on rows and others depends on columns. And then distance equations have been used to make a decision in matching stage. The presented system was tested using a CASIA Multi-Spectral Palm-print Image Database contains 7,200 palm images captured from 100 different people. The recognition system gives a percent of 91.6% of correct recognition. The proposed system needs software requirements which was a program that written in a Visual C# programming language. It provides to the user a Graphical User Interface (GUI) to display the operating events of this system and  make decisions.
