dirichletAreas: Compute Areas of Tiles in Dirichlet Tessellation

Description

Calculates the area of each tile in the Dirichlet-Voronoi tessellation of a point pattern.

Usage

dirichletAreas(X)

Arguments

X

Point pattern (object of class "ppp").

Value

Numeric vector with one entry for each point of X.

Details

This is an efficient algorithm to calculate the areas of the tiles in the Dirichlet-Voronoi tessellation.

If the window of X is a binary pixel mask, the tile areas are computed by counting pixels. Otherwise the areas are computed exactly using analytic geometry.

If any points of X are duplicated, the duplicates will have tile area zero.
