overlap.owin: Compute Area of Overlap

Description

Computes the area of the overlap (intersection) of two windows.

Usage

overlap.owin(A, B)

Value

A single numeric value.

Arguments

A,B

Windows (objects of class "owin").

Author

Details

This function computes the area of the overlap between the two windows A and B.

If one of the windows is a binary mask, then both windows are converted to masks on the same grid, and the area is computed by counting pixels. Otherwise, the area is computed analytically (using the discrete Stokes theorem).

Examples

  A <- square(1)
  B <- shift(A, c(0.3, 0.2))
  overlap.owin(A, B)
