octagon

octagon

skimage.morphology.octagon(m, n, dtype=) [source]

Generates an octagon shaped structuring element.

For a given size of (m) horizontal and vertical sides and a given (n) height or width of slanted sides octagon is generated. The slanted sides are 45 or 135 degrees to the horizontal axis and hence the widths and heights are equal.

Parameters:	m : int The size of the horizontal and vertical sides. n : int The height or width of the slanted sides.
Returns:	selem : ndarray The structuring element where elements of the neighborhood are 1 and 0 otherwise.
Other Parameters:
	dtype : data-type The data type of the structuring element.
