Bayesian stereo matching

open access: yesComputer Vision and Image Understanding, 2005
A Bayesian framework is proposed for stereo vision where solutions to both the model parameters and the disparity map are posed in terms of predictions of latent variables, given the observed stereo images. A mixed sampling and deterministic strategy is adopted to balance between effectiveness and efficiency: the parameters are estimated via Markov ...

Local Stereo Matching Based on Support Weight With Motion Flow for Dynamic Scene

open access: yesIEEE Access, 2016
Stereo matching is one of the most important and challenging subjects in the field of stereo vision. The disparity obtained in stereo matching can represent depth information in 3-D world to a great extent and shows great importance in stereo field.

HIGH-PRECISION DEM PRODUCTION FOR SPACEBORNE STEREO SAR IMAGES BASED ON SIFT MATCHING AND REGION-BASED LEAST SQUARES MATCHING [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Generally, there are two ways to generate Digital Elevation Model (DEM) using synthetic aperture radar (SAR) data, which are Interferometer Synthetic Aperture Radar(InSAR) and radargrammetry. Considering the disadvantages of InSAR data, such as the limit

Stereo sensitivity depends on stereo matching

open access: yesJournal of Vision, 2005
Stereoacuity thresholds, measured with bar targets, rise as the absolute disparity of the bars is increased. One explanation for this rise is that, as the bars are moved away from the fixation plane, the stereo system uses coarser mechanisms to encode the bars' disparity; coarse mechanisms are insensitive to small changes in target disparity, resulting

Coarse-to-Fine Stereo Matching Network Based on Multi-Scale Structural Information Filtrating

open access: yesIEEE Access, 2023
Stereo vision measurement is widely applied in tasks such as autonomous driving and 3D scene reconstruction. Accurately obtaining the disparity of stereo images relies on effective stereo matching algorithms.

Hyperspectral Light Field Stereo Matching [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2019
In this paper, we describe how scene depth can be extracted using a hyperspectral light field capture (H-LF) system. Our H-LF system consists of a 5 x 6 array of cameras, with each camera sampling a different narrow band in the visible spectrum. There are two parts to extracting scene depth.

Segment-based adaptive window and multi-feature fusion for stereo matching

open access: yesJournal of Algorithms & Computational Technology, 2016
As to the problems of local stereo matching methods, such as matching window selection difficulty, fuzzy disparity edges and low accuracy in weak texture regions, this paper proposes an efficient stereo matching algorithm to improve the stereo matching ...

An Improved Stereo Matching Algorithm Based on Joint Similarity Measure and Adaptive Weights

open access: yesApplied Sciences, 2022
Stereo matching is the operation of obtaining the parallax value between two images by matching all the corresponding image points in the two images, thus obtaining the dense parallax image between the two images.

Estimation of disparity map of stereo image pairs using spatial domain local Gabor wavelet

open access: yesIET Computer Vision, 2015
The stereo matching problem takes two images captured by nearby cameras and attempts to recover quantitative disparity information. Most of the existing stereo matching algorithms find it difficult to estimate disparity in the occlusion, discontinuities ...

Stereo Matching with Nonlinear Diffusion [PDF]

open access: yesInternational Journal of Computer Vision, 1996
One of the central problems in stereo matching (and other image registration tasks) is the selection of optimal window sizes for comparing image regions. This paper addresses this problem with some novel algorithms based on iteratively diffusing support at different disparity hypotheses, and locally controlling the amount of diffusion based on the ...
