UTIRIS Image Repository

University of Tehran IRIS (UTIRIS) image repository is the first iris biometric databank registered in two distinct sessions of Visible Wavelength (VW) and Near InfraRed (NIR) imaging during 24-27th of June 2007. The database is constructed with 1540 images from 79 individuals from both right and left eyes demonstrated in 158 classes in total. The individuals are numbered the same in NIR and VW sessions. The Database is a copyright of Control and Intelligent Processing Centre of Excellence (CIPCE) at School of Electrical and Computer Engineering (ECE) in the University of Tehran.
