LOCALIZING THE IRIS THROUGH MEMETIC ALGORITHMS

open access: yesApplied Artificial Intelligence, 2009
An iris recognition system requires efficient image processing techniques in order to duly represent and interpret the iris structural characteristics of an individual. The first processing stage should be the identification of the iris region in an eye image.

Reliable Eyelid Localization for Iris Recognition [PDF]

open access: yes, 2008
This article presents a new eyelid localization algorithm based on a parabolic curve fitting. To deal with eyelashes, low contrast or false detection due to iris texture, we propose a two steps algorithm. First, possible edge candidates are selected by applying an edge detection on a restricted area inside the iris.

Segmentation-free Direct Iris Localization Networks

open access: yes2023 IEEE/CVF Winter Conference on Applications of Computer Vision (WACV), 2023
This paper proposes an efficient iris localization method without using iris segmentation and circle fitting. Conventional iris localization methods first extract iris regions by using semantic segmentation methods such as U-Net. Afterward, the inner and outer iris circles are localized using the traditional circle fitting algorithm.
