Chaotic Krill Herd with Deep Transfer Learning-Based Biometric Iris Recognition System

Biometric verification has become essential to authenticate the individuals in public and private places. Among several biometrics, iris has peculiar features and its working mechanism is complex in nature. The recent developments in Machine Learning and Deep Learning approaches enable the development of effective iris recognition models. With this motivation, the current study introduces a novel Chaotic Krill Herd with Deep Transfer Learning Based Biometric Iris Recognition System (CKHDTL-BIRS). The presented CKHDTL-BIRS model intends to recognize and classify iris images as a part of biometric verification. To achieve this, CKHDTL-BIRS model initially performs Median Filtering (MF)-based preprocessing and segmentation for iris localization. In addition, MobileNet model is also utilized to generate a set of useful feature vectors. Moreover, Stacked Sparse Autoencoder (SSAE) approach is applied for classification. At last, CKH algorithm is exploited for optimization of the parameters involved in SSAE technique. The proposed CKHDTL-BIRS model was experimentally validated using benchmark dataset and the outcomes were examined under several aspects. The comparison study results established the enhanced performance of CKHDTL-BIRS technique over recent approaches.
