Performing Iris Segmentation by Using Geodesic Active Contour (GAC)

Abstract

A novel iris segmentation technique based on active contour is proposed in this paper. Our approach includes two important issues, pupil segmentation and iris circle calculation. If the correct center position and radius of pupil can be found in the tested image, we can precisely segment the iris. The accuracy of our proposed method for ICE dataset is around 92%, and also reached high accuracy level of 79% for UBIRIS. Our results demonstrate that the proposed iris segmentation method can perform well with high accuracy for Iris segmentation in images.
