Some Properties of Gromov–Hausdorff Distances [PDF]

open access: yesDiscrete & Computational Geometry, 2012
The Gromov–Hausdorff distance between metric spaces appears to be a useful tool for modeling some object matching procedures. Since its conception it has been mainly used by pure mathematicians who are interested in the topology generated by this distance, and quantitative consequences of the definition are not very common.

Automated detection system of metro tunnel lining crack using dynamic snake convolution

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 26, Page 4521-4542, 7 November 2025.
Abstract Inspecting defects in tunnel linings is a crucial part of tunnel maintenance work. Traditional tunnel inspection methods are generally inefficient, making it difficult to complete intensive inspection tasks and provide detailed characteristic data of cracks within the limited maintenance time. In this research, a deep learning–driven automatic

An Improved Automatic Algorithm for Global Eddy Tracking Using Satellite Altimeter Data

open access: yesRemote Sensing, 2017
In this paper, we propose a new hybrid mesoscale eddy tracking method to enhance the eddy tracking accuracy from global satellite altimeter data. This method integrates both physical and geometric eddy properties (including the distance between eddies ...

COMPUTING THE HAUSDORFF DISTANCE BETWEEN CURVED OBJECTS

open access: yesInternational Journal of Computational Geometry & Applications, 2008
The Hausdorff distance between two sets of curves is a measure for the similarity of these objects and therefore an interesting feature in shape recognition. If the curves are algebraic computing the Hausdorff distance involves computing the intersection points of the Voronoi edges of the one set with the curves in the other.

Prospective Evaluation of Automated Contouring for CT-Based Brachytherapy for Gynecologic Malignancies

open access: yesAdvances in Radiation Oncology
Purpose: The use of deep learning to auto-contour organs at risk (OARs) in gynecologic radiation treatment is well established. Yet, there is limited data investigating the prospective use of auto-contouring in clinical practice. In this study, we assess

3D Segmentation for Multi-Organs in CT Images

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2013
The study addresses the challenging problem of automatic segmentation of the human anatomy needed for radiation dose calculations. Three-dimensional extensions of two well-known state-of-the art segmentation techniques are proposed and tested for ...
