dirichlet.vertices: Vertices of Dirichlet Tessellation

Description

Computes the Dirichlet-Voronoi tessellation of a point pattern and extracts the vertices of the tiles.

Usage

dirichlet.vertices(X)

Arguments

X
Point pattern (object of class "ppp").

Value

  • Point pattern (object of class "ppp") in the same window as X.

Details

The Dirichlet tessellation is described in the help for

This function computes the Dirichlet-Voronoi tessellation of X (see dirichlet) and extracts the vertices of the tiles of the tessellation. These vertices are the locations which are locally farthest away from X, that is, where the distance function of X reaches a local maximum.

The Dirichlet tessellation of X is computed using dirichlet. The vertices of all tiles of the tessellation are extracted. Any vertex which lies on the boundary of the window of X is deleted. The remaining vertices are returned, as a point pattern, without duplicated entries.
