Iris Localization via Pulling and Pushing [PDF]
18th International Conference on Pattern Recognition (ICPR'06), 2006 Iris localization is a critical module in iris recognition because it defines the inner and outer boundaries of iris region used for feature analysis. State-of-the-art iris localization methods need to implement a bruteforce search of the large parameter space, which is time-consuming and sensitive to noises.

A unified approach for automated segmentation of pupil and iris in on-axis images
Computer Methods and Programs in Biomedicine Update, 2022 We propose a unified approach for the automatic and accurate segmentation of the pupil and iris from on-axis grayscale eye images. The segmentation of pupil and iris is achieved with Basis-spline-based active contour and circular active contour ...

Iris Recognition Using Hybrid Self-Organizing Map Classifier and Daugman’s Algorithm
Jurnal RESTI (Rekayasa Sistem dan Teknologi Informasi), 2023 One of the neural network algorithms that can be used in iris recognition is self-organizing map (SOM). This algorithm has a weakness in determining the initial weight of the network, which is generally carried out randomly, which can result in a ...

The still under-investigated role of cognitive deficits in PML diagnosis [PDF]
, 2017 Background: Despite cognitive deficits frequently represent the first clinical manifestations of Progressive Multifocal Leukoencephalopathy (PML) in Natalizumab-treated MS patients, the importance of cognitive deficits in PML diagnosis is still under ...
