Spherical Layout Implementation using Centroidal Voronoi Tessellations

, 2009
The 3D tree visualization faces multiple challenges: the election of an appropriate layout, the use of the interactions that make the data exploration easier and a metaphor that helps in the process of information understanding. A good combination of these elements will result in a visualization that effectively conveys the key features of a complex ...

Comparative assessment of projection and clustering method combinations in the analysis of biomedical data

Informatics in Medicine Unlocked
Background: Clustering on projected data is common in biomedical research analysis. Principal component analysis (PCA) is widely used for projection, focusing on data dispersion (variance), while clustering identifies data concentrations (neighborhood ...

Hexagrid-Voronoi transition in structural patterns for tall buildings

Fracture and Structural Integrity, 2018
In this paper, a first insight into the role that non-conventional structural patterns might play in the design of tall buildings is presented. The idea is to explore the mechanical properties of selected non-conventional structural patterns, in the form

Voronoi tessellation and hierarchical model based texture image segmentation

Tongxin xuebao, 2014
A regional and statistical based algorithm for texture image segmentation was proposed. The Voronoi tessella-tion was used for partitioning the domain of an image into sub-regions corresponding to the components of homogenous regions, to which the ...

Predicting Trajectories Using Voronoi Tessellation

, 2023
Die genaue Vorhersage zukünftiger Positionen von Akteuren ist eine wichtige Aufgabe in verschiedenen Bereichen wie autonomes Fahren, intelligente Fahrassistenten, Robotik und der Videospielindustrie. Aufgrund der stochastischen Natur menschlicher Bewegungen und des Einflusses externer Faktoren ist eine hohe Vorhersagegenauigkeit jedoch nach wie vor ein

Optimization of centroidal Voronoi tessellations

In this paper, we investigate the optimization of Centroidal Voronoi Tessellations (CVT) under geometric constraints. For this purpose, we minimize a linear combination of the standard CVT energy functional with terms involving geometric attributes such as area and perimeter.
