Extract Pixel Centres as Point Pattern
Given a pixel image or binary mask window, extract the centres of all pixels and return them as a point pattern.
pixelcentres(X, W = NULL, ...)
Pixel image (object of class
"im") or window (object of class
- Optional window to contain the resulting point pattern.
- Optional arguments defining the pixel resolution.
If the argument
X is a pixel image, the result is a point
pattern, consisting of the centre of every pixel whose pixel value
X is a window which is a binary mask, the result is a point
pattern consisting of the centre of every pixel inside the window
(i.e. every pixel for which the mask value is
X is first converted to a window, then
converted to a mask using
as.mask, then handled as
A point pattern (object of class
