mmcbisector
N-Conditional bisector.

Synopsis

function y = mmcbisector ( f , B , n )

Input

f Image Binary image
B Structuring Element
n Double

positive integer ( filtering rate)

Output

y Image Binary image

Description

mmcbisector creates the binary image y by performing a filtering of the morphological skeleton of the binary image f, relative to the structuring element B. The strength of this filtering is controlled by the parameter n. Particularly, if n=0, y is the morphological skeleton of f itself.

Examples

a=mmreadgray('blob2.tif');

b=mmcbisector(a,mmsebox,1);

c=mmcbisector(a,mmsebox,3);

d=mmcbisector(a,mmsebox,10);

mmshow(a,b);

mmshow(a,c);

mmshow(a,d);
a,b a,c
a,d

Equation

Algorithm

function y=mmcbisector_equ(f, B, n)
  y = mmbinary(zeros(size(f)));
  for i=0:length(f)
    nb = mmsesum(B,i);
    nbp = mmsesum(B,i+1);
    f1 = mmero(f,nbp);
    f2 = mmcdil(f1,f,B,n);
    f3 = mmsubm(mmero(f,nb),f2);
    y = mmunion(y,f3);
  end;
