Lipschitz-Killing curvatures of excursion sets for two-dimensional random fields

H Biermé, E Di Bernardino, C Duval, A Estrade - 2019 - projecteuclid.org
In the present paper we study three geometrical characteristics for the excursion sets of a
two-dimensional stationary isotropic random field. First, we show that these characteristics …

Surface area and volume of excursion sets observed on point cloud based polytopic tessellations

R Cotsakis, E Di Bernardino… - The Annals of Applied …, 2024 - projecteuclid.org
The excursion set of a C 2 smooth random field carries relevant information in its various
geometric measures. From a computational viewpoint, one never has access to the …

Statistics for Gaussian random fields with unknown location and scale using Lipschitz‐Killing curvatures

E Di Bernardino, C Duval - Scandinavian Journal of Statistics, 2022 - Wiley Online Library
In the present article we study the average of Lipschitz‐Killing (LK) curvatures of the
excursion set of a stationary isotropic Gaussian field X on ℝ 2. The novelty is that the field …

Goodness-of-fit tests for complete spatial randomness based on Minkowski functionals of binary images

B Ebner, N Henze, MA Klatt, K Mecke - 2018 - projecteuclid.org
We propose a class of goodness-of-fit tests for complete spatial randomness (CSR). In
contrast to standard tests, our procedure utilizes a transformation of the data to a binary …

Pixel isotropy test based on directional perimeters

M Abaach, H Biermé, E Di Bernardino, A Estrade - Spatial Statistics, 2024 - Elsevier
In this paper we consider the so-called directional perimeters of a thresholded grey-level
image. These geometrical quantities are built by considering separately the horizontal and …

Normal convergence of nonlocalised geometric functionals and shot-noise excursions

R Lachièze-Rey - The Annals of Applied Probability, 2019 - JSTOR
This article presents a complete second-order theory for a large class of geometric
functionals on homogeneous Poisson input. In particular, the results do not require the …

Empirical modelling and analysis of phase noise in OFDM systems

Q Duan, H Du, J Xue, F Li - IET Communications, 2024 - Wiley Online Library
Based on empirical data of an orthogonal frequency division multiplexing system in realistic
environments of next‐generation cellular networks, a new analytical model of phase noise …

Betti numbers of Gaussian excursions in the sparse regime

G Thoppe, SR Krishnan - arxiv preprint arxiv:1807.11018, 2018 - arxiv.org
Random field excursions is an increasingly vital topic within data analysis in medicine,

On the geometry of excursion sets: theoretical and computational guarantees

R Cotsakis - 2024 - theses.hal.science
The excursion set EX (u) of a real-valued random field X on R^ d at a threshold level u∈ R is
the subset of the domain R^ d on which X exceeds u. Thus, the excursion set is random, and …
