Title
Automatic Iris Segmentation Based on Local Areas
Abstract
In this paper a novel and robust method for automatic iris segmentation based on local areas is described. Such method is composed of three main parts. (a) Find the local rectangle region which has the minimum intensity mean and extend it to locate pupil. (b) Select two small local sector areas including the outer boundaries of iris to locate outer iris. (c) Translate the iris from polar coordinates into Cartesian coordinates and normalize it to fixed size to compensate the stretching of the iris texture as the pupil changes in size and remove the nonconcentricity of the iris and the pupil. The method was implemented using CASIA Iris image databases. The experimental results show that the proposed method has an encouraging result with an overall accuracy of 98.42%.
