Mastcam Image Resolution Enhancement with Application to Disparity Map Generation for Stereo Images with Different Resolutions [PDF]

open access: yesSensors, 2019
In this paper, we introduce an in-depth application of high-resolution disparity map estimation using stereo images from Mars Curiosity rover’s Mastcams, which have two imagers with different resolutions.

Disparity Map Generation from Illumination Variant Stereo Images Using Efficient Hierarchical Dynamic Programming [PDF]

open access: yesThe Scientific World Journal, 2014
A novel hierarchical stereo matching algorithm is presented which gives disparity map as output from illumination variant stereo pair. Illumination difference between two stereo images can lead to undesirable output.

Accuracy analysis of lossless and lossy disparity map compression

open access: yesAin Shams Engineering Journal, 2022
In this paper, we analysed lossless and lossy compression of disparity (depth) images with low range resolution. For that goal, the well-known publicly available Middlebury dataset is used with stereo image pairs, their disparity ground truths and ...

Iterative roll angle estimation from dense disparity map

open access: yesMediterranean Conference on Embedded Computing, 2018
The v-disparity map is predominantly used to estimate the parameters of the vertical profile of the road surface. Once the road surface is modelled, an object that lies away from it can be detected and determined as either an obstacle or a pothole.

Disparity Refinement for Stereo Matching of High-Resolution Remote Sensing Images Based on GIS Data

open access: yesRemote Sensing
With the emergence of the Smart City concept, the rapid advancement of urban three-dimensional (3D) reconstruction becomes imperative. While current developments in the field of 3D reconstruction have enabled the generation of 3D products such as Digital

Enhancing the Ground Truth Disparity by MAP Estimation for Developing a Neural-Net Based Stereoscopic Camera

open access: yesSensors
This paper presents a novel method to enhance ground truth disparity maps generated by Semi-Global Matching (SGM) using Maximum a Posteriori (MAP) estimation. SGM, while not producing visually appealing outputs like neural networks, offers high disparity

Image Segmentation and Feature Extraction Using Sift-Sad Algorithm for Disparity Map Generation

open access: yesCommunications, 2013
In this paper, a stereo matching algorithm based on image segments and disparity measurement using stereo images is presented. We propose the hybrid segmentation algorithm that is based on a combination of the Belief Propagation and Mean Shift algorithms

CONTINUOUS 3D-LABEL SEMI-GLOBAL MATCHING FOR SATELLITE STEREO [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
We present Continuous 3D-Label Semi-Global Matching (CoSGM), a new dense stereo matching algorithm for satellite stereo. CoSGM overparameterizes the disparity map as an array of local planes, so it can regularize the first-order smoothness of the ...

AMBIGUITY CONCEPT IN STEREO MATCHING PIPELINE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
In a 3D reconstruction pipeline, stereo matching step aims at computing a disparity map representing the depth between image pair. The evaluation of the disparity map can be done through the estimation of a confidence metric.
