Recognition of iris based on visible light (VL) imaging is a difficult problem because of the light reflection from the cornea. Nonetheless, pigment melanin provides a rich feature source in VL, which is unavailable in near-infrared (NIR) imaging. This is due to the biological spectroscopy of eumelanin, a chemical not stimulated in NIR. In this case, a plausible solution to observe such patterns may be provided by an adaptive procedure using a variational technique on the image histogram. To…

Iris Recognition: Comparing Visible-Light Lateral and Frontal Illumination to NIR Frontal Illumination
TLDR
This article presents an image acquisition method that enhances viewing the structural information of the muscle fibers of the iris on the resulting image and produces more separable distributions than those of the NIR device, and much better distribution than using frontal visible-light alone.

Fusing the information in visible light and near-infrared images for iris recognition
TLDR
An iris recognition system that uses images acquired in both near-infrared and visible lights and demonstrates the necessity to process both VL and NIR images to recognize irides, and proves that fusion can compensate the lack of input image information.
Iris biometrie: Is the near-infrared spectrum always the best?
TLDR
Experimental results indicate that the VL and NIR images provide complementary features for the iris pattern and their fusion improves the recognition performance, and the experiments indicate that cross-channel matching between VL-NIR images is feasible.
A novel framework for cross-spectral iris matching
TLDR
Experimental and comparison results demonstrate that the proposed framework achieves state-of-the-art cross-spectral matching and indicate that the VL and NIR images provide complementary features for the iris pattern and their fusion improves notably the recognition performance.
An Investigation of Quality Aspects of Noisy Colour Images for Iris Recognition
TLDR
New quality metrics are presented to assess the image characteristics with regard to focus, entropy, reflections, pupil constriction and pupillary boundary contrast to suggest the existence of different characteristics for these channels and could be exploited for use in the design and evaluation of iris recognition systems.
Reflection removal and feature extraction techniques in non-cooperative visible eye images for iris recognition
TLDR
The research proposed the development of two combined methods to improve the iris recognition system which identifies and classifies between reflections and nonreflections and uses score combination of multiscale at the end of the process to increase the matching score.
Cross-spectrum periocular authentication for NIR and visible images using bank of statistical filters
TLDR
An ocular image database collected using the visible and NIR cameras is employed and a new framework employing a bank of Binarized Statistical Image filters along with χ2 distance metric along with simple fusion to handle the cross-spectrum data is proposed.
Ocular recognition databases and competitions: a survey
TLDR
A survey of the databases created for ocular recognition, detailing their protocols and how their images were acquired and some relevant works applying deep learning techniques to ocular Recognition point out new challenges and future directions.
Cross-Spectral Iris Matching for Surveillance Applications
TLDR
Two methods for cross-spectral iris recognition capable of matching iris images in different lighting conditions are proposed and results indicate that the VL and NIR images provide complementary features for the iris pattern and their fusion improves the recognition performance.

TLDR
The basic idea is that local sharp variation points, denoting the appearing or vanishing of an important image structure, are utilized to represent the characteristics of the iris.

This paper presents a comparative study of the performance from the iris identification using log-Gabor, Haar wavelet, DCT and FFT based features and suggests the combination of these two matchers is most promising, both in terms of performance and the computational complexity.
