Contrast sensitivity functions in autoencoders [PDF]

open access: yesJournal 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 ...

Predicting individual contrast sensitivity functions from acuity and letter contrast sensitivity measurements. [PDF]

open access: yesJournal of Vision, 2016
Contrast sensitivity (CS) is widely used as a measure of visual function in both basic research and clinical evaluation. There is conflicting evidence on the extent to which measuring the full contrast sensitivity function (CSF) offers more functionally ...

Contrast sensitivity and higher-order aberrations in Keratoconus subjects

open access: yesScientific Reports, 2021
This study analyzes the relationship between contrast-sensitivity and higher-order aberrations (HOA) in mild and subclinical-keratoconus in subjects with good visual-acuity (VA).

Measuring contrast sensitivity

open access: yesVision 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.

Noise provides new insights on contrast sensitivity function. [PDF]

open access: yesPLoS 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 ...

Visual acuity and contrast sensitivity of adult zebrafish

open access: yesFrontiers in Zoology, 2012
Background The aim of this study was to evaluate the visual acuity of adult zebrafish by assessing the optokinetic reflex. Using a modified commercially available optomotor device (OptoMotry®), virtual three-dimensional gratings of variable spatial ...

Measuring the Contrast Sensitivity Function in Non-Neovascular and Neovascular Age-Related Macular Degeneration: The Quantitative Contrast Sensitivity Function Test

open access: yesJournal of Clinical Medicine, 2021
Age-related macular degeneration (AMD) affects various aspects of visual function compromising patients’ functional vision and quality of life. Compared to visual acuity, contrast sensitivity correlates better with vision-related quality of life and ...
