mmcero
Erode an image conditionally.

Synopsis

y = mmcero ( f , g , b = NullStrel, n = 1 )

Input

f Image Gray-scale (uint8 or uint16) or binary image

g Image Gray-scale (uint8 or uint16) or binary image

Conditioning image.
b Structuring Element

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

(number of iterations).

Default: 1 (1)

Output

y Image

Description

mmcero creates the image y by eroding the image f by the structuring element b conditionally to g. This operator may be applied recursively n times.

Examples

f = mmneg(mmtext('hello'))
mmshow(f)
g = mmdil(f,mmseline(7,90))
mmshow(g)
a1=mmcero(g,f,mmsebox())
mmshow(a1)
a13=mmcero(a1,f,mmsebox(),13)
mmshow(a13)
f g a1 a13
