Abstract

Iris segmentation is a critical stage in the whole iris recognition process. In this paper, a procedure of iris segmentation is presented which was designed on the basis of the natural properties of the iris. The proposed procedure consists of two main steps: circles localization and non-iris region detection. In our method, we took into consideration of some typical problems most likely to appear in practice. And experiments show that our method can achieve good results and robust as well.
