dilation code does not work

%dilation code

close all;

clear all;

clc;

A=imread( 'fingerprint.tif' );

%Structuring element

b = [0 1 0; 1 1 1; 0 1 0];

C=padarray(A,[0 3]);

D=false(size(A));

for i=1:size(C,1)

for j=1:size(C,2)-6

D(i,j)=sum(B&C(i,j:j+6));

end

end

figure(1),imshow(D);title('dilation');

You aren't using your structuring element. Is that on purpose? And do you need it to be a loop?

Ihave error this step D(i,j)=sum(B&C(i,j:j+6));

[darova]

What is wrong with it?

[KALYAN ACHARJYA]

What is "B" here?

You are trying to "&" operation on two different sizes matrices???

here

b & C(i,j:j+6)

[aslan memo]

b ıs the Structuring element

[Rik]

No, b is your structuring element, B doesn't exist. And you haven't explained if you need a loop or not.

Why not simply use imdilate()?
