Iris Segmentation Code Based on the GST

Iris Segmentation Code
Contact: Fernando Alonso-Fernandez

Introduction

This page provides a software code for iris segmentation based on the Generalized Structure Tensor (GST). The software accepts as input grayscale and RGB images in any format supported by Matlab "imread" (uint8 only). It outputs the following information of the input iris image:

• Segmentation circles of the iris region (inner and outer boundaries) as well as eyelids (straight line)
• Irregular (non-circular) iris boundaries fitted by active contours
• Estimated eye center (computed at the beginning and used to guide segmentation of iris boundaries)
• Intermediate images after contrast normalization, specular reflection removal, and eyelash removal
• Complex edge map of the input image
• Binary segmentation mask
