[mmsebox] [Up] [mmsedisk] Structuring Elements

mmsecross
Diamond structuring element and elementary 3x3 cross.

Synopsis

B = mmsecross( r = 1 )

Implemented in Python.

Input

r	Double (radius). Default: `1`

Output

B	Structuring Element

Description

mmsecross creates the structuring element B formed by r successive Minkowski additions of the elementary cross (i.e., the 3x3 cross centered at the origin) with itself. If r=0, B is the unitary set that contains the origin. If r=1, B is the elementary cross itself.

Examples

>>> b1 = mmsecross()

>>> print mmseshow(b1)

[[0 1 0]
 [1 1 1]
 [0 1 0]]

>>> b2 = mmsecross(2)

>>> print mmseshow(b2)

[[0 0 1 0 0]
 [0 1 1 1 0]
 [1 1 1 1 1]
 [0 1 1 1 0]
 [0 0 1 0 0]]

Equation
