Efficient computation of clipped Voronoi diagram for mesh generation [PDF]

, 2011
International audienceThe Voronoi diagram is a fundamental geometric structure widely used in various fields, especially in computer graphics and geometry computing. For a set of points in a compact domain (i.e.

Coverage improvement using Voronoi diagrams in directional sensor networks

IET Wireless Sensor Systems, 2021
Recently, the area coverage problem has emerged in the directional sensor network (DSN), where the sensor's sensed area depends on its working direction and viewing angle.

Compact and Efficient Topological Mapping for Large-Scale Environment with Pruned Voronoi Diagram

Drones, 2022
Topological maps generated in complex and irregular unknown environments are meaningful for autonomous robots’ navigation. To obtain the skeleton of the environment without obstacle polygon extraction and clustering, we propose a method to obtain high ...

Data‐Driven Modeling of Composition–Processing–Microstructure Relations for Recycled Aluminum Cast Alloys

Advanced Science, EarlyView.
Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

Gridvoronoi: An Efficient Spatial Index for Nearest Neighbor Query Processing

IEEE Access, 2019
In this paper, based upon Voronoi Diagram, we propose GridVoronoi which is a novel spatial index that enables users to find the spatial nearest neighbour (NN) from two-dimensional (2D) datasets in almost O(1) time.

The Voronoi diagram in structural optimisation [PDF]

, 2008
In the course of the exploration of computational means in the architectural design process, in order to investigate more complex, adaptive geometries, the Voronoi diagram has recently gained some attention, as a structure that is modular but not ...

Holes Processing in Voronoi Diagram with Rectangular Sites for the Comparative Analysis of Slab Deformations

Информатика и автоматизация
In this article, a new Voronoi diagram algorithm with rectangular sites and holes is proposed. The algorithm is based on the existing Voronoi diagram algorithm with the L∞ distance metric by Papadopoulou E. and Lee D.-T.

A Voronoi diagram approach for detecting defects in 3D printed fiber-reinforced polymers from microscope images

Computational Visual Media, 2022
Fiber-reinforced polymer (FRP) composites are increasingly popular due to their superior strength to weight ratio. In contrast to significant recent advances in automating the FRP manufacturing process via 3D printing, quality inspection and defect ...
