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 ...

Binocular contrast vision at and above threshold [PDF]

open access: yes, 2006
A fundamental problem for any visual system with binocular overlap is the combination of information from the two eyes. Electrophysiology shows that binocular integration of luminance contrast occurs early in visual cortex, but a specific systems ...

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.

Perception of relative depth interval : Systematic biases in perceived depth [PDF]

open access: yes, 2012
Given an estimate of the binocular disparity between a pair of points and an estimate of the viewing distance, or knowledge of eye position, it should be possible to obtain an estimate of their depth separation.

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

Methods for dichoptic stimulus presentation in functional magnetic resonance imaging - a review [PDF]

open access: yes, 2009
Dichoptic stimuli (different stimuli displayed to each eye) are increasingly being used in functional brain imaging experiments using visual stimulation.
