Monocular blur alters the tuning characteristics of stereopsis for spatial frequency and size [PDF]

open access: yesRoyal Society Open Science, 2016
Our sense of depth perception is mediated by spatial filters at different scales in the visual brain; low spatial frequency channels provide the basis for coarse stereopsis, whereas high spatial frequency channels provide for fine stereopsis.

Clinical study of the effect of refractive status on stereopsis in children with intermittent exotropia

open access: yesBMC Ophthalmology, 2018
Background Many studies have shown that patients with intermittent exotropia have different degrees of damage to their stereopsis function. The purpose of this study is to explore the effect of different refractive status on stereopsis in children with ...

What is Stereopsis? [PDF]

open access: yesi-Perception, 2012
“Stereopsis” refers to the characteristically vivid qualitative impression of 3D structure that is observed when real (or simulated-3D) scenes are viewed binocularly.

Two independent mechanisms for motion-in-depth perception : evidence from individual differences [PDF]

open access: yes, 2010
Our forward-facing eyes allow us the advantage of binocular visual information: using the tiny differences between right and left eye views to learn about depth and location in three dimensions.

Comparison of stereopsis thresholds measured with conventional methods and a new eye tracking method.

open access: yesPLoS ONE, 2023
PurposeStereopsis is the ability to perceive depth using the slightly different views from two eyes. This study aims to conduct innovative stereopsis tests using the objective data outputted by eye tracking technology.MethodsA laptop and an eye tracker ...

Stereo and motion parallax cues in human 3D vision: can they vanish without a trace? [PDF]

open access: yes, 2006
In an immersive virtual reality environment, subjects fail to notice when a scene expands or contracts around them, despite correct and consistent information from binocular stereopsis and motion parallax, resulting in gross failures of size constancy (A.

Differences in the Visual Performances of Patients with Strabismus, Amblyopia, and Healthy Controls

open access: yesBioengineering, 2022
The aim of this paper is to use the new definition of amblyopia and to define the overall visual performance of healthy controls (HCs), patients with strabismus (PS), and patients with refractive amblyopia (PRA), based on the interaction of selected ...
