ADAPTIVE INITIAL CONTOUR AND PARTLY-NORMALIZATION ALGORITHM FOR IRIS SEGMENTATION OF BLURRY IRIS IMAGES

open access: yesJournal of ICT, 2022
Iris segmentation is a process to isolate the accurate iris region from the eye image for iris recognition. Iris segmentation on non-ideal and noisy iris images is accurate with active contour. Nevertheless, it is currently unclear on how active contour

RAG‐Net: ResNet‐50 attention gate network for accurate iris segmentation

open access: yesIET Image Processing, 2022
Iris segmentation is an important step in the process of iris recognition. Iris images collected under non‐cooperative conditions always contain various noise, which is a challenge for iris segmentation.

Review of iris segmentation and recognition using deep learning to improve biometric application

open access: yesJournal of Intelligent Systems, 2023
Biometric recognition is essential for identifying people in security, surveillance, and mobile device authentication. Iris recognition (IR) biometrics is exact because it uses unique iris patterns to identify individuals.

A unified approach for automated segmentation of pupil and iris in on-axis images

open access: yesComputer 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 ...
