Bilaterally Weighted Patches for Disparity Map Computation
Image Processing On Line, 2015 Visual correspondence is the key for 3D reconstruction in binocular stereovision. Local methods perform block-matching to compute the disparity, or apparent motion, of pixels between images. The simplest approach computes the distance of patches, usually

A novel cell structure‐based disparity estimation for unsupervised stereo matching
IET Image Processing, 2022 It is well known that preserving depth edges is an effective solution for achieving the accurate disparity map in stereo matching, but many state‐of‐the‐art methods do not preserve depth edges well.

Hierarchical Stereo Matching in Two-Scale Space for Cyber-Physical System
Sensors, 2017 Dense disparity map estimation from a high-resolution stereo image is a very difficult problem in terms of both matching accuracy and computation efficiency. Thus, an exhaustive disparity search at full resolution is required.

Sparse Stereo Disparity Map Densification Using Hierarchical Image Segmentation
International Symposium on Mathematical Morphology and Its Application to Signal and Image Processing, 2017 We describe a novel method for propagating disparity values using hierarchical segmentation by waterfall and robust regression models. High confidence disparity values obtained by state of the art stereo matching algorithms are interpolated using a ...

Dense spatio‐temporal stereo matching for intelligent driving systems
IET Image Processing, 2021 This paper addresses the problem of matching stereo images acquired by a stereo system mounted aboard an intelligent vehicle. The main idea behind the new method consists in involving temporal matching between a current stereo pair and its preceding one ...

Equal Baseline Camera Array—Calibration, Testbed and Applications
Applied Sciences, 2021 This paper presents research on 3D scanning by taking advantage of a camera array consisting of up to five adjacent cameras. Such an array makes it possible to make a disparity map with a higher precision than a stereo camera, however it preserves the ...
