Owen code for imopen morphology function why not work ?how to solve ?

clc

clear all

close all

im=imread('C:\Users\ASLAN\Desktop\ders\image processing\hw2\fingerprint.tif');

[m,n]=size(im);

a=[0 1 0;1 1 1;0 1 0];

for i=1:m

for j=1:n

if a(i,j)==0

im(i,j)=0;

[i,j]=min(im);

mm=min(im);

end

end

end

figure

imshow (mm);

[KALYAN ACHARJYA]

[i,j]=min(im) ;

Can you elaborate more, what you are trying to do?

[aslan memo]

in morphology, if use (imopen) there are 2 step

1 -imerode

if a(i,j)==0

im(i,j)=0;

2-imopen

in imopen select the minimum number

[i,j]=min(im);

mm=min(im);
