Abstract

Iris location is an important part in an iris recognition system. Its precision and speed influence the performance of the whole system. To overcome the drawbacks of some popular algorithms with respect to these aspects, this paper proposes a novel approach which reduces the effects of eyelash occlusion and boundary blurring, two major affected factors. With this approach, the inner boundary is quickly located by searching a coarse center and the outer one by image converting, enhancing, and differentiating. The proposed approach is compared with two commonly used ones by experimental results on the CASIA database.
