mmseunion
Union of structuring elements

Synopsis

B = mmseunion ( B1 , B2 )

Input

B1 Structuring Element

B2 Structuring Element

Output

B Structuring Element

Description

mmseunion creates a structuring element from the union of two structuring elements.

Examples

b1 = mmseline(5)
mmseshow(b1)
array([False, False, False, False,  True,  True,  True,  True,  True], dtype=bool)
b2 = mmsedisk(3)
mmseshow(b2)
array([[False, False,  True,  True,  True, False, False],
       [False,  True,  True,  True,  True,  True, False],
       [ 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]], dtype=bool)
b3 = mmseunion(b1,b2)
mmseshow(b3)
        
array([[False, False, False,  True,  True,  True, False, False, False],
       [False, False,  True,  True,  True,  True,  True, False, False],
       [False,  True,  True,  True,  True,  True,  True,  True, False],
       [False,  True,  True,  True,  True,  True,  True,  True,  True],
       [False,  True,  True,  True,  True,  True,  True,  True, False],
       [False, False,  True,  True,  True,  True,  True, False, False],
       [False, False, False,  True,  True,  True, False, False, False]], dtype=bool)
