Iris segmentation is one of the crucial steps in building an iris recognition system since it
affects the accuracy of the iris matching significantly. This segmentation should accurately …

A categorical study on iris localization, its challenges and techniques is carried out here.
This survey comprehends the historical evolution and present state-of-the-art in iris …

The random distribution of features in an iris image texture allows to perform iris-based
personal authentication with high confidence. We propose three new iris representations …

Infrared and visible images fusion based on edge‐preserving can improve the fused result
in a clear outline. However, there exists the performance degradation caused by some …

A system of methods for the detection and segmentation of iris in frontal eye images is
presented. Input data are images used in modern iris recognition systems. Coordinates of …

Edge‐preserving filters have been applied to Multi‐Scale Decomposition (MSD) for fusion of
infrared and visible images. Traditional edge‐preserving MSDs may hardly make satisfied …

The iris recognition system depends heavily on the accuracy of the selected region of the
iris. The paper considers the task of selecting the iris region in an eye image. To solve the …

Passwords are ubiquitous in today's world, as are forgetting and stealing them. Biometric
signs are harder to steal and impossible to forget. This paper presents a complete system of …

The problem of detecting precise pupil border in eye image given its initial circular
approximation is addressed with circular shortest path method. Brightness gradient direction …

An algorithm of approximate location of iris center in image is presented. It is based on
Hough transformation for circles. Problem is set in a way to detect only iris center position …
