[mmimg2se] [Up] [mmsecross] Structuring Elements

mmsebox
Create a box structuring element.

Synopsis

B = mmsebox ( r = 1 )

Input

r Double Non-negative integer.

Radius.

Default: 1 (1)

Output

B Structuring Element

Description

mmsebox creates the structuring element B formed by r successive Minkowski additions of the elementary square (i.e., the 3x3 square 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 square itself.

Examples

b1 = mmsebox()
mmseshow(b1)
array([[ True,  True,  True],
       [ True,  True,  True],
       [ True,  True,  True]], dtype=bool)
b2 = mmsebox(2)
mmseshow(b2)
        
array([[ True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True]], dtype=bool)
