mmcloseth - Closing Top Hat.

Synopsis
y = mmcloseth( f, b )
Input
f: Gray-scale (uint8 or uint16) or binary image (logical uint8).
b: Structuring element. Default: Elementary cross (mmsecross).
Output
y: Gray-scale (uint8 or uint16) or binary image (logical uint8). (Same type of f).
Description
mmcloseth creates the image y by subtracting the image f of its morphological closing by the structuring element b.
Examples 
a = mmreadgray('danaus.tif');
mmshow(a);
b = mmcloseth(a,mmsebox(5));
mmshow(b);
image
(a)
image
(b)

Algorithm 
function y=mmcloseth_equ( f, b)
  y = mmsubm(mmclose(f, b),f);
