Meridian-Specific and Post-Optical Deficits of Spatial Vision in Human Astigmatism: Evidences From Psycho-Physical and EEG Scalings

open access: yesFrontiers in Psychology, 2021
Previous studies have demonstrated that orientation-specific deprivation in early life can lead to neural deficits of spatial vision in certain space, and can even result in meridional amblyopia (MA).

The role of monocularly visible regions in depth and surface perception [PDF]

open access: yes, 2009
The mainstream of binocular vision research has long been focused on understanding how binocular disparity is used for depth perception. In recent years, researchers have begun to explore how monocular regions in binocularly viewed scenes contribute to ...

Sensitivity to disparity corrugations in peripheral vision

open access: yesVision Research, 1998
Disparity discrimination thresholds are known to increase with both retinal eccentricity and distance from the horopter. However, little is known about how the detectability of cyclopean gratings varies with retinal position. Thresholds for disparity corrugations were measured as a function of corrugation frequency for different visual eccentricities ...

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.

Efficient Propagation Method for Angularly Consistent 4D Light Field Disparity Maps

open access: yesIEEE Access, 2023
Light Field (LF) imaging, since it conveys both spatial and angular scene information, can facilitate computer vision tasks such as depth/disparity estimation.

In-Band Disparity Compensation for Multiview Image Compression and View Synthesis [PDF]

open access: yes, 2010
This paper presents a novel framework to achieve scalable multiview image compression and view synthesis. The open-loop wavelet-lifting scheme for geometric filtering has been exploited to achieve signal-to-noise ratio scalability and view-type ...

Individual objective versus subjective fixation disparity as a function of forced vergence.

open access: yesPLoS ONE, 2018
Inaccuracy in the vergence eye position ("fixation disparity") can occur despite a fusion stimulus. When measured with eye trackers, this inaccuracy is referred to as "objective fixation disparity".
