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

Non-contact, in-vivo, functional, and structural ophthalmic imaging using multimodal photoacoustic remote sensing (PARS) microscopy and optical coherence tomography (OCT) [PDF]
arXiv, 2021 Early diagnosis of ocular diseases improves the understanding of pathophysiology and helps with accurate monitoring and effective treatment. Advanced multimodal ocular imaging platforms play a crucial role in the visualization of the ocular components and provide clinicians with a valuable tool for evaluating different eye diseases. Here, for the first

Pinwheel stabilization by ocular dominance segregation [PDF]
Phys. Rev. Lett. 102, 208101 (2009), 2008 We present an analytical approach for studying the coupled development of ocular dominance and orientation preference columns. Using this approach we demonstrate that ocular dominance segregation can induce the stabilization and even the production of pinwheels by their crystallization in two types of periodic lattices. Pinwheel crystallization depends

The relationship between Fully Connected Layers and number of classes for the analysis of retinal images [PDF]
arXiv, 2020 This paper experiments with the number of fully-connected layers in a deep convolutional neural network as applied to the classification of fundus retinal images. The images analysed corresponded to the ODIR 2019 (Peking University International Competition on Ocular Disease Intelligent Recognition) [9], which included images of various eye diseases ...

Black Sun: Ocular Invisibility of Relativistic Luminous Astrophysical Bodies [PDF]
Journal of High Energy Physics, Gravitation and Cosmology, 2016,
2, 562-570, 2015 The relativistic Doppler shifting of visible electromagnetic radiation to beyond the human ocular range reduces the incident radiance of the source. Consequently, luminous astrophysical bodies (LABs) can be rendered invisible with sufficient relativistic motion. This paper determines the proper distance as a function of relativistic velocity at which a

PPG Signals for Hypertension Diagnosis: A Novel Method using Deep Learning Models [PDF]
arXiv, 2023 Hypertension is a medical condition characterized by high blood pressure, and classifying it into its various stages is crucial to managing the disease. In this project, a novel method is proposed for classifying stages of hypertension using Photoplethysmography (PPG) signals and deep learning models, namely AvgPool_VGG-16.

Hypertension Detection From High-Dimensional Representation of Photoplethysmogram Signals [PDF]
arXiv, 2023 Hypertension is commonly referred to as the "silent killer", since it can lead to severe health complications without any visible symptoms. Early detection of hypertension is crucial in preventing significant health issues. Although some studies suggest a relationship between blood pressure and certain vital signals, such as Photoplethysmogram (PPG ...

Label-free, non-contact, in-vivo ophthalmic imaging using photoacoustic remote sensing microscopy [PDF]
, 2020 We present the first label-free, non-contact, in-vivo imaging of the ocular vasculature using photoacoustic remote sensing (PARS) microscopy. Both anterior and posterior segments mouse eye were imaged. Vasculature of iris, sclera and retina tissues were clearly resolved.

Core determinants of quality criteria for mhealth for hypertension: evidence from machine learning instruments [PDF]
arXiv, 2023 Uncontrolled hypertension is a global problem that needs to be addressed. Despite the many mHealth solutions in the market, the nonadherence relative to intended use jeopardizes treatment success. Although investigating user experience is one of the most important mechanisms for understanding mHealth discontinuance, surprisingly, the core determinants ...

Probing Fairness of Mobile Ocular Biometrics Methods Across Gender on VISOB 2.0 Dataset [PDF]
25th International Conference on Pattern Recognition (ICPR) 2020|
Milan, Italy, 2020 Recent research has questioned the fairness of face-based recognition and attribute classification methods (such as gender and race) for dark-skinned people and women. Ocular biometrics in the visible spectrum is an alternate solution over face biometrics, thanks to its accuracy, security, robustness against facial expression, and ease of use in mobile
