Detailed Description

template<typename TCoordType>
class itk::VoronoiDiagram2D< TCoordType >

Implements the 2-Dimensional Voronoi Diagram.

Given a set of seed points, the Voronoi Diagram partitions the plane into regions, each region is a collection of all pixels that is closest to one particular seed point than to other seed points. VoronoiDiagram2D is a mesh structure for storing the Voronoi Diagram, can be Generated by itkVoronoiDiagram2DGenerator.

Template parameters for VoronoiDiagram2D:

TCoordType = The type associated with the coordniation of the seeds and the resulting vertices.
