Iris recognition is a challenging task in a noisy imaging environment. Nowadays
researcher's primary focus is to develop reliable Iris recognition System that can work in …

In this paper, a multilevel thresholding based on Artificial Bee Colony metaheuristic is
proposed as a pre-segmentation step in the iris detection process. Multilevel thresholding …

This paper presents a fast segmentation of iris portion from an eye image in an iris
recognition system. In iris segmentation, we have to find the inner boundary (between pupil …

In the health care systems, a high security level is required to protect extremely sensitive
patient records. The goal is to provide a secure access to the right records at the right time …

This paper presents a novel approach for automatic pupil segmentation. The proposed
algorithm uses local histogram-based threshold, area and eccentricity that looks for the …

The fundamental step in implementing an eyebased interface is the exact localization of
user eye pupil and iris and separating them from other parts of the eye. This paper presents …

Iris segmentation is the process of defining the valid part of the eye image used for further
processing (feature extraction, matching and decision making). Segmentation of the iris …

Iris segmentation is a vital forepart module in iris recognition because it isolates the valid
image region used for subsequent processing such as feature extraction. Traditional iris …

Pupil localization plays a key role in recognizing the biological characteristics of iris that is
self-evident. In recent years, the most common procedures to localize the pupil have been …

The field of ophthalmology is in need of more support as it is unable to meet the need of the
growing population. This thesis considers procedures which may be used as part of an …
