Contrast sensitivity functions in autoencoders [PDF]
Journal of Vision, 2022 Three decades ago, Atick et al. suggested that human frequency sensitivity may emerge from the enhancement required for a more efficient analysis of retinal images. Here we reassess the relevance of low-level vision tasks in the explanation of the Contrast Sensitivity Functions (CSFs) in light of (1) the current trend of using artificial neural ...

Octopaminergic modulation of contrast sensitivity [PDF]
Frontiers in Integrative Neuroscience, 2012 Sensory systems adapt to prolonged stimulation by decreasing their response to prevailing stimulus conditions. Whereas visual motion adaptation has traditionally been studied in immobilized animals, recent work indicates that the animal’s behavioral ...

Contrast Sensitivity and Glaucoma
Journal of Glaucoma, 2019 Spatial contrast sensitivity decline occurs in different types and stages of glaucoma. In this short review we discuss methods of assessing contrast sensitivity, the role of contrast sensitivity in the pathogenesis of glaucoma and its practical application in clinical practice.

Development of Dynamic Contrast Sensitivity Chart [PDF]
British and Irish Orthoptic JournalBackground: Dynamic visual acuity (DVA) is a complex visual function that requires the observer to detect a moving target, to visually acquire it by eye movements, and to resolve critical details contained in it, in a relatively brief time exposure ...

Effects of COVID-19 on the contrast sensitivity [PDF]
Brazilian Journal of Medical and Biological ResearchThere are significant gaps in understanding the extent of the damage caused by COVID-19, with few publications examining its link to contrast sensitivity function (CSF).

Measuring contrast sensitivity
Vision Research, 2013 Contrast sensitivity defines the threshold between the visible and invisible, which has obvious significance for basic and clinical vision science. Fechner's 1860 review reported that threshold contrast is 1% for a remarkably wide range of targets and conditions.

Predicting contrast sensitivity functions with digital twins [PDF]
Scientific ReportsWe developed and validated digital twins (DTs) for contrast sensitivity function (CSF) across 12 prediction tasks using a data-driven, generative model approach based on a hierarchical Bayesian model (HBM).

Noise provides new insights on contrast sensitivity function. [PDF]
PLoS ONE, 2014 Sensitivity to luminance difference, or contrast sensitivity, is critical for animals to survive in and interact with the external world. The contrast sensitivity function (CSF), which measures visual sensitivity to spatial patterns over a wide range of ...
