Visual Pigments, Ocular Filters and the Evolution of Snake Vision [PDF]

Molecular Biology and Evolution, 2016
Much of what is known about the molecular evolution of vertebrate vision comes from studies of mammals, birds and fish. Reptiles (especially snakes) have barely been sampled in previous studies despite their exceptional diversity of retinal photoreceptor complements.

Investigating Fairness of Ocular Biometrics Among Young, Middle-Aged, and Older Adults [PDF]

arXiv, 2021
A number of studies suggest bias of the face biometrics, i.e., face recognition and soft-biometric estimation methods, across gender, race, and age groups. There is a recent urge to investigate the bias of different biometric modalities toward the deployment of fair and trustworthy biometric solutions. Ocular biometrics has obtained increased attention

LensAge index as a deep learning-based biological age for self-monitoring the risks of age-related diseases and mortality

Nature Communications, 2023
Age is closely related to human health and disease risks. However, chronologically defined age often disagrees with biological age, primarily due to genetic and environmental variables.

CDNet: Contrastive Disentangled Network for Fine-Grained Image Categorization of Ocular B-Scan Ultrasound [PDF]

arXiv, 2022
Precise and rapid categorization of images in the B-scan ultrasound modality is vital for diagnosing ocular diseases. Nevertheless, distinguishing various diseases in ultrasound still challenges experienced ophthalmologists. Thus a novel contrastive disentangled network (CDNet) is developed in this work, aiming to tackle the fine-grained image ...

Quantitative interocular suppression in children with intermittent exotropia

Frontiers in Neuroscience, 2023
PurposeWe have demonstrated that the depth of unbalanced interocular suppression can be quantified by balancing the interocular luminance differences required when both eyes are viewing simultaneously.

Ocular Recognition Databases and Competitions: A Survey [PDF]

, 2019
The use of the iris and periocular region as biometric traits has been extensively investigated, mainly due to the singularity of the iris features and the use of the periocular region when the image resolution is not sufficient to extract iris information.

Compact CNN Models for On-device Ocular-based User Recognition in Mobile Devices [PDF]

IEEE Symposium on Computational Intelligence in Biometrics and Identity Management (IEEE CIBIM) 2021, 2021
A number of studies have demonstrated the efficacy of deep learning convolutional neural network (CNN) models for ocular-based user recognition in mobile devices. However, these high-performing networks have enormous space and computational complexity due to the millions of parameters and computations involved. These requirements make the deployment of
