[mmsebox] [Up] [mmsedisk] Structuring Elements

mmsecross
Diamond structuring element and elementary 3x3 cross.

Synopsis

function B = mmsecross ( r )

Input

r Double

Default: 1

(radius).

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;

mmseshow(b1)

ans =
     0     1     0
     1     1     1
     0     1     0

b2 = mmsecross(2);

mmseshow(b2)

ans =
     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
