The killifish visual system as an in vivo model to study brain aging and rejuvenation

open access: yesnpj Aging and Mechanisms of Disease, 2021
Worldwide, people are getting older, and this prolonged lifespan unfortunately also results in an increased prevalence of age-related neurodegenerative diseases, contributing to a diminished life quality of elderly.

An Investigation of a Biomimetic Optical System and an Evaluation Model for the Qualitative Analysis of Laser Interference Visual Levels

open access: yesBiomimetics
To objectively quantify the level of visual interference induced by lasers, we developed a biomimetic optical system designed to emulate human vision. This system is based on an optical model of the eye and synthetic imaging principles, allowing it to ...

The visual system of zebrafish and its use to model human ocular Diseases [PDF]

open access: yesDevelopmental Neurobiology, 2012
AbstractFree swimming zebrafish larvae depend mainly on their sense of vision to evade predation and to catch prey. Hence, there is strong selective pressure on the fast maturation of visual function and indeed the visual system already supports a number of visually driven behaviors in the newly hatched larvae.

A Tele-Operated Display With a Predictive Display Algorithm [PDF]

open access: yes, 2019
Tele-operated display systems with head mounted displays (HMD) are becoming popular as visual feedback systems for tele-operation systems. However, the users are suffered from time-varying bidirectional delays caused by the latency and limited bandwidth ...

Electrophysiological model of human temporal contrast sensitivity based on SSVEP

open access: yesFrontiers in Neuroscience, 2023
The present study aims to connect the psychophysical research on the human visual perception of flicker with the neurophysiological research on steady-state visual evoked potentials (SSVEPs) in the context of their application needs and current ...

A Visual Human-Computer Interaction System Based on Hybrid Visual Model

open access: yesSecurity and Communication Networks, 2022
The traditional human-computer interaction is mainly through the mouse, keyboard, remote control, and other peripheral equipment electromagnetic signal transmission. This paper aims to build a visual human-computer interaction system through a series of deep learning and machine vision models, so that people can achieve complete human-computer ...

A Bayesian approach to the aperture problem of 3D motion perception [PDF]

open access: yes, 2012
We suggest a geometric-statistical approach that can be ap- plied to the 3D aperture problem of motion perception. In simulations and psychophysical experiments we study per- ceived 3D motion direction in a binocular viewing geometry by ...

“Descriptive Risk-Averse Bayesian Decision-Making,” a Model for Complex Biological Motion Perception in the Human Dorsal Pathway

open access: yesBiomimetics, 2022
Biological motion perception is integral not only to survival but also to the social life of human beings. Identifying the underlying mechanisms and their associated neurobiological substrates has been a matter of investigation and debate for some time ...
