Compute Areas of Tiles in Dirichlet Tessellation
Calculates the area of each tile in the Dirichlet-Voronoi tessellation of a point pattern.
- Point pattern (object of class
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.
- Numeric vector with one entry for each point of
aa <- dirichletAreas(cells)
