Centroidal Voronoi Tessellation of Streamlines for Flow Visualization
2013 10th International Symposium on Voronoi Diagrams in Science and Engineering, 2013Centroidal Voronoi tessellation (CVT) and its extensions have a wide spectrum of applications including computational geometry, image processing, cellular biology and scientific visualization etc. In this paper, we propose the concept of the complete streamline and the CVT of streamlines, and then formulate the computation of CVT of complete ...

Constructing Centroidal Voronoi Tessellations on Surface Meshes
2009Centroidal Voronoi tessellations can be constructed using iterative improvement methods such as Lloyd’s method. Using iterative improvement methods implies that the convergence speed and the quality of the results depend on the initialization methods.

Point cloud resampling using centroidal Voronoi tessellation methods
Computer-Aided Design, 2018Abstract This paper presents a novel technique for resampling point clouds of a smooth surface. The key contribution of this paper is the generalization of centroidal Voronoi tessellation (CVT) to point cloud datasets to make point resampling practical and efficient.

On The Characterization and Uniqueness of Centroidal Voronoi Tessellations
SIAM Journal on Numerical Analysis, 2017Summary: Vector quantization is a classical signal-processing technique with significant applications in data compression, pattern recognition, clustering, and data stream mining. It is well known that for critical points of the quantization energy, the tessellation of the domain is a centroidal Voronoi tessellation.

Computation and properties of Centroidal Voronoi Tessellation
2008 IEEE International Conference on Shape Modeling and Applications, 2008Centroidal Voronoi Tessellation (CVT) is a variational framework of computing an optimal geometric structure based on the Voronoi Diagram, and is used in many applications of computer graphics and geometric processing. I will present several recent results on CVT.

Planning and Optimization of Cellular Networks through Centroidal Voronoi Tessellations
2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015The fifth generation (5G) of wireless networks will connect not only persons but also things, in a massive and previously unheard-of scale. Therefore, engineers and researchers need to develop methods and solutions to 1) satisfy the increasing demand, and 2) plan, maintain, and optimize networks that are envisioned to provide services to a highly ...

An Edge-Weighted Centroidal Voronoi Tessellation Model for Image Segmentation
IEEE Transactions on Image Processing, 2009Centroidal Voronoi tessellations (CVTs) are special Voronoi tessellations whose generators are also the centers of mass (centroids) of the Voronoi regions with respect to a given density function and CVT-based methodologies have been proven to be very useful in many diverse applications in science and engineering. In the context of image processing and
