Centroidal Voronoi Tessellation Based Proper Orthogonal Decomposition Analysis [PDF]

open access: yes, 2003
Proper orthogonal decompositions (POD) have been used to systematically extract the most energetic modes while centroidal Voronoi tessellations (CVT) have been used to systematically extract best representatives. We combine the ideas of CVT and POD into a hybrid method for model reduction.

Nonhomogeneous distributions and optimal quantizers for Sierpi\'nski carpets

open access: yes, 2016
The purpose of quantization of a probability distribution is to estimate the probability by a discrete probability with finite support. In this paper, a nonhomogeneous probability measure $P$ on $\mathbb R^2$ which has support the Sierpi\'nski carpet ...

Geodesic Centroidal Voronoi Tessellations: Theories, Algorithms and Applications

open access: yes, 2019
Nowadays, big data of digital media (including images, videos and 3D graphical models) are frequently modeled as low-dimensional manifold meshes embedded in a high-dimensional feature space. In this paper, we summarized our recent work on geodesic centroidal Voronoi tessellations(GCVTs), which are intrinsic geometric structures on manifold meshes.

Parallel High-Order Anisotropic Meshing Using Discrete Metric Tensors [PDF]

open access: yes
This paper presents a metric-aligned meshing algorithm that relies on the Lp-Centroidal Voronoi Tesselation approach. A prototype of this algorithm was first presented at the Scitech conference of 2018 and this work is an extension to that paper.
