Usage

clear_border(image, win = NULL, r = image$xstep * 2, output_mask = FALSE)

Arguments

image	binary image (instance of im object)
win	Optional. Window/mask that defines edges (instance of owin object)
r	Optional. Radius of morphological erosion operation to use to define the edge. This will determine the 'thickness' of the edge. Defaults to 2px.
output_mask	Optional. Logical value to indicate whether a mask of objects should be returned. If FALSE a labelled image will be returned.

Value
