Iris localization is one of the most important step in iris based recognition systems. Iris localization means locating the inner boundary (pupil localization) and outer boundary of iris. Both boundaries of the iris are nearly circular which are surrounded by pupil, sclera, eyelashes and eyelids. In the proposed algorithm inner boundary (Pupil) is localized by using two region properties Eccentricity and Area without using any iterative method. On the other hand the outer boundary of iris is located using Gaussian derivatives. The proposed algorithm is tested on CASIA-1 Iris database. Experimental results show that the proposed method is quite fast efficient and accurate method.
