mmclohole
Close holes of binary and gray-scale images.

Synopsis

y = mmclohole ( f , Bc = NullStrel )

Input

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

Bc Structuring Element

( connectivity).

Default: NullStrel (3x3 elementary cross)

Output

y Image

(same datatype of f).

Description

mmclohole creates the image y by closing the holes of the image f, according with the connectivity defined by the structuring element Bc.The images can be either binary or gray-scale.

Examples

Binary image:
a = mmreadgray('pcb1bin.tif')
b = mmclohole(a)
mmshow(a)
mmshow(b)
a b
Gray-scale image:
a = mmreadgray('boxdrill-B.tif')
b = mmclohole(a)
mmshow(a)
mmshow(b)
a b
