ON THE HAUSDORFF MEASURE OF CERTAIN PLANE SET PROJECTIONS

open access: yesPesquimat, 2014
A characterization of plane sets whose projection have zero Hausdorff measure is given. This is obtained through the study of an angular density introduced first by Marstrand [2].

An evaluation of performance measures for arterial brain vessel segmentation

open access: yesBMC Medical Imaging, 2021
Background Arterial brain vessel segmentation allows utilising clinically relevant information contained within the cerebral vascular tree. Currently, however, no standardised performance measure is available to evaluate the quality of cerebral vessel ...

Statistical properties of topological Collet-Eckmann maps [PDF]

open access: yes, 2006
We study geometric and statistical properties of complex rational maps satisfying the Topological Collet-Eckmann Condition. We show that every such a rational map possesses a unique conformal probability measure of minimal exponent, and that this measure

Exact Hausdorff measure on the boundary of a Galton--Watson tree

open access: yes, 2007
A necessary and sufficient condition for the almost sure existence of an absolutely continuous (with respect to the branching measure) exact Hausdorff measure on the boundary of a Galton--Watson tree is obtained.

On the equality of Hausdorff measure and Hausdorff content [PDF]

open access: yes, 2014
We are interested in situations where the Hausdorff measure and Hausdorff content of a set are equal in the critical dimension. Our main result shows that this equality holds for any subset of a self-similar set corresponding to a nontrivial cylinder of ...

Hausdorff Dimension and Topological Entropies of a Solenoid

open access: yesEntropy, 2020
The purpose of this paper is to elucidate the interrelations between three essentially different concepts: solenoids, topological entropy, and Hausdorff dimension.

Spaces of non-additive measures generated by triangular norms

open access: yesМатематичні Студії, 2023
We consider non-additive measures on the compact Hausdorff spaces, which are generalizations of the idempotent measures and max-min measures. These measures are related to the continuous triangular norms and they are defined as functionals on the spaces ...

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
