Abstract

Aiming at the limitations of the existing iris localization algorithm, a new method of iris localization is proposed in this paper. The iris image is preprocessed firstly, the center coordinates and the radius of the iris inner edge is located by using Canny operator algorithm; the rough outer edge of the iris is got by the Canny operator secondly, and then the rough outer edge is divided into several small regions, the real edge of the outer edge of the iris can be got by using multi threshold segmentation in small regions. Because of the coupling relationship between the inner and outer edge of iris, the real center coordinates and the radius of the outer edge is located by the least square method. The experimental results show that this method can more quickly and accurately locate out the inner and outer edge of the iris.
