The Dual Gromov-Hausdorff Propinquity [PDF]

open access: yes, 2014
Motivated by the quest for an analogue of the Gromov-Hausdorff distance in noncommutative geometry which is well-behaved with respect to C*-algebraic structures, we propose a complete metric on the class of Leibniz quantum compact metric spaces, named ...

Method and Algorithms for Computing Fuzzy Fréchet and Hausdorff Distance

open access: yesMathematics
Accurate image similarity assessment is a key problem in computer vision, particularly in segmentation and classification problems. Classical Hausdorff and Fréchet metrics provide pointwise distance values and do not allow similarity to be evaluated in ...

Robust Geometry Estimation using the Generalized Voronoi Covariance Measure [PDF]

open access: yes, 2015
The Voronoi Covariance Measure of a compact set K of R^d is a tensor-valued measure that encodes geometric information on K and which is known to be resilient to Hausdorff noise but sensitive to outliers. In this article, we generalize this notion to any

The topology of theρ-hausdorff distance

open access: yesAnnali di Matematica Pura ed Applicata, 1991
As the authors say ``the Hausdorff distance... works well as long as the sets lie in a bounded region. In many applications one has to deal with unbounded sets or with collections of bounded sets which are not uniformly bounded''. To deal with these situations this paper builds on earlier work of two of the authors and others and is a comprehensive ...

Color-Based Image Retrieval Using Perceptually Modified Hausdorff Distance

open access: yesEURASIP Journal on Image and Video Processing, 2008
In most content-based image retrieval systems, the color information is extensively used for its simplicity and generality. Due to its compactness in characterizing the global information, a uniform quantization of colors, or a histogram, has been the ...

Some properties of the Blumberg's hyper-log-logistic curve

open access: yesBiomath, 2018
The paper considers the sigmoid function definedthrough the hyper-log-logistic model introduced by Blumberg. We study the Hausdorff distance of this sigmoid to the Heaviside function, which characterises the shape of switching from 0 to 1.

Real-time image matching for navigation system based on genetic algorithm

open access: yesTongxin xuebao, 2008
In order to meet requirement that scene matching aided navigation system must get aircraft position error real-timely, an image matching algorithm based on genetic algorithm and weighted Hausdorff distance was proposed.

Almost periodic functions on Hausdorff almost periodic time scales

open access: yesAdvances in Difference Equations, 2017
This paper is devoted to generalizing the notion of almost periodic functions on time scales. We introduce a new class of almost periodic time scales called Hausdorff almost periodic time scales by using the Hausdorff distance and propose a more general ...

On the regularity of the Hausdorff distance between spectra of perturbed magnetic Hamiltonians

open access: yes, 2012
We study the regularity properties of the Hausdorff distance between spectra of continuous Harper-like operators. As a special case we obtain H\"{o}lder continuity of this Hausdorff distance with respect to the intensity of the magnetic field for a large
