Iris recognition with deformation and occlusion estimation

Definition

Algorithms for iris recognition usually consist of applying feature extraction on raw iris pattern, then matching against features. However, two important techniques in machine learning and pattern recognition, namely, probabilistic graphical model and advanced correlation filters, have not been used for iris recognition. By using probabilistic graphical models for iris texture deformation, with the observation being the correlation output derived from applying correlation filters to local iris regions, problems of iris pattern local deformations and occlusions can be handled and recognition performance can be improved over that of the conventional iris recognition algorithms.

Introduction

In the past two decades, iris recognition has emerged as one of the most promising modalities for biometric recognition. Many algorithms have been proposed to improve the recognition performance of iris recognition....
