On the inverse problem of binocular 3D motion perception. [PDF]

open access: yesPLoS Computational Biology, 2010
It is shown that existing processing schemes of 3D motion perception such as interocular velocity difference, changing disparity over time, as well as joint encoding of motion and disparity, do not offer a general solution to the inverse optics problem ...

Size matters: How reaching and vergence movements are influenced by the familiar size of stereoscopically presented objects.

open access: yesPLoS ONE, 2019
The knowledge about the usual size of objects-familiar size-is known to be a taken into account for distance perception. The influence of familiar size on action programming is less clear and has not yet been tested with regard to vergence eye movements.

Stereoscopic 3D geometric distortions analyzed from the viewer's point of view.

open access: yesPLoS ONE, 2020
Stereoscopic 3D (S3D) geometric distortions can be introduced by mismatches among image capture, display, and viewing configurations. In previous work of S3D geometric models, geometric distortions have been analyzed from a third-person perspective based

Simple reaction times to cyclopean stimuli reveal that the binocular system is tuned to react faster to near than to far objects. [PDF]

open access: yesPLoS ONE, 2018
Binocular depth perception is an important mechanism to segregate the visual scene for mapping relevant objects in our environment. Convergent evidence from psychophysical and neurophysiological studies have revealed asymmetries between the processing of

The development of active binocular vision under normal and alternate rearing conditions

open access: yeseLife, 2021
The development of binocular vision is an active learning process comprising the development of disparity tuned neurons in visual cortex and the establishment of precise vergence control of the eyes.

How Does Binocular Disparity Affect the Impressions in Viewing Stereograms?

open access: yesi-Perception, 2012
We examined how the size of binocular disparity affects the impressions in different dimensions, as well as apparent depth, in viewing line-contoured stereograms, random dot stereogram, and stereoscopic pictures of naturalistic scenes. We used a semantic

Real-Time Dense Reconstruction with Binocular Endoscopy Based on StereoNet and ORB-SLAM

open access: yesSensors, 2023
Binocular endoscopy is gradually becoming the future of minimally invasive surgery (MIS) thanks to the development of stereo vision. However, some problems still exist, such as the low reconstruction accuracy, small surgical field, and low computational ...

Statistics of Natural Binocular Images

open access: yesi-Perception, 2013
Understanding exactly how disparity is processed from binocular views of the world is a long standing problem in vision. It has been hypothesised that an important first step in visual processing is to generate an energy efficient sparse coding of visual

A laminar cortical model of stereopsis and 3D surface perception: Closure and da Vinci stereopsis [PDF]

open access: yes, 2004
A laminar cortical model of stereopsis and 3D surface perception is developed and simulated. The model describes how monocular and binocular oriented filtering interact with later stages of 3D boundary formation and surface filling-in in the LGN and ...
