Development of Iris Image Classification Framework using Multi-Layer CNN Architecture

Abstract

This paper proposes a multi-layer Convolutional Neural Network (CNN) framework for iris image classification, targeting left and right eye recognition across 46 subjects. A custom five-layer CNN was trained for 200 epochs with a learning rate of 0.0001, effectively learning discriminative features from iris textures. The model achieved a training accuracy of 97.90% with a loss of 0.4116, and a testing accuracy of 93.09% with a loss of 0.6837, demonstrating robust generalization to unseen data. The results highlight the potential of multi-layer CNN architectures for reliable iris-based biometric systems, enabling accurate and automated eye classification. The key contribution of this work is the demonstration that a compact five-layer CNN can achieve high accuracy in binary left-right iris classification, offering an efficient and scalable solution for biometric authentication.
