Abstract
Iris localization is one of the most important steps in iris recognition system and determines the accuracy of matching. In this study, an efficient technique for iris localization is proposed. First, the direct least square fitting of ellipse is used to detect the inner boundaries of iris. Then the integro-differential operator is used to detect the outer boundaries of iris. Experimental results show that the technique has a good performance, which improve the speed and accuracy on iris localization.
