A Novel Factor Graph-Based Optimization Technique for Stereo Correspondence Estimation [PDF]

open access: yes, 2021
Dense disparities among multiple views is essential for estimating the 3D architecture of a scene based on the geometrical relationship among the scene and the views or cameras. Scenes with larger extents of heterogeneous textures, differing scene illumination among the multiple views and with occluding objects affect the accuracy of the estimated ...

The perceived depth from disparity as function of luminance contrast [PDF]

open access: yes, 2016
Does human vision show the contrast invariance expected of an ideal stereoscopic system for computing depth from disparity? We used random-dot stereograms to investigate the luminance contrast effect on perceived depth from disparity. The perceived depth

Sensitivity to Binocular Disparity is Reduced by Mild Traumatic Brain Injury [PDF]

open access: yes, 2017
Purpose: The impairment of visual functions is one of the most common complaints following mild traumatic brain injury (mTBI). Traumatic brain injury–associated visual deficits include blurred vision, reading problems, and eye strain.

Stereo Matching with Cost Volume based Sparse Disparity Propagation [PDF]

open access: yesarXiv, 2022
Stereo matching is crucial for binocular stereo vision. Existing methods mainly focus on simple disparity map fusion to improve stereo matching, which require multiple dense or sparse disparity maps. In this paper, we propose a simple yet novel scheme, termed feature disparity propagation, to improve general stereo matching based on matching cost ...

PATCH BASED STEREO MATCHING USING CONVOLUTIONAL NEURAL NETWORK

open access: yesICTACT Journal on Image and Video Processing, 2021
The paper presents a new Convolutional Neural Network (CNN) architecture, called stacked stereo CNN, for computing disparity map from stereo images. In stacked stereo CNN, left and right image patches are stacked back-to-back and fed to a single tower ...
