R: Compute Area of Overlap

overlap.owin {spatstat.geom} | R Documentation

## Compute Area of Overlap

### Description

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

### Usage

    overlap.owin(A, B)

### Arguments

`A,B` | Windows (objects of class `"owin"`).

### 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).

### Value

A single numeric value.
