Hi, i write this code for compute shift between to picture and match to picture for increase quality. i have error when i want to run shifting in two end for please help for this problem.

im = imread("000010.jpg");

im = im2double(im);

im2 = imread("000019.jpg");

im2 = im2double(im2);

p1 = im(150:200 , 280:330);

big_alpa = 0;

ii=0;

jj=0;

for i = 10:665

for j = 50:900

p2 = im2(i:i+50 , j:j+50);

s=0;

a=0;

b=0;

for k = 1:50

for h = 1:50

s = s + (p1(k,h) * p2(k,h));

a = a + (p1(k,h) * p1(k,h));

b = b + (p2(k,h) * p2(k,h));

end

alpa = ((s*s) / (a * b));

if(alpa > big_alpa)

big_alpa = alpa;

ii =i;

jj =j;

end

new1 = ones(740 , 1300 );

for i = 5:715

for j =5:1275

new1(i,j) = (im(i,j) + im2(i+150-ii , j + 280-jj))/2;

end

imshow(new1)

Well, since I have no idea how big the images are, I'm just going to assume that

k-(150-ii)

and maybe even

l-(280-jj)

are less than one, kind of like what the error suggests.

Errors like this are what happen when you presume image geometry instead of using size() and checking that your indices don't exceed the array boundaries.

Also, is it just me, or is the code you posted not even the code that is giving you the error?
