Centroidal Voronoi Tesselations (CVT's)


Summer/Fall 2001 I worked with Max Gunzburger and John Burkhardt studying CVTs.

Background: A Voronoi diagram is the set of cells formed by asociating each point in space with the closest generator to that point using some distance metric. One might think of a generator as a post office, and each cell as the set of houses nearest to that post office. Centroidal means that the generator is also the center of mass for a cell.

Why study the CVT?
-Image Compression
-Sound Compression
-Stock Market Analysis
-Clustering
-Database Structure
-Resource Management
-Gene Expression Analysis
-Biology(Zdravko Jeremic)
-Sphere Packing
-Structural Properties
