[mmseshow] [Up] [mmsetrans] Structuring Elements

mmsesum
N-1 iterative Minkowski additions

Synopsis

NB = mmsesum ( B = NullStrel, N = 1 )

Input

B Structuring Element

Default: NullStrel (3x3 elementary cross)
N Double Non-negative integer.

Default: 1 (1)

Output

NB Structuring Element

Description

mmsesum creates the structuring element NB from N - 1 iterative Minkowski additions with the structuring element B.

Examples

b = mmimg2se(mmbinary([[1, 1, 1], [1, 1, 1], [0, 1, 0]]))
mmseshow(b)
array([[ True,  True,  True],
       [ True,  True,  True],
       [False,  True, False]], dtype=bool)
b3 = mmsesum(b,3)
mmseshow(b3)
array([[ True,  True,  True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True,  True,  True],

       [False,  True,  True,  True,  True,  True, False],
       [False, False,  True,  True,  True, False, False],
       [False, False, False,  True, False, False, False]], dtype=bool)
b = mmsedisk(1,'2D','CITY-BLOCK','NON-FLAT');
