it is very simple to find correlation between two images of same size.
a=imread('firstimage.tif');
b=imread('secondimage.tif');
if you mean correlation coefficient, you can program manually the function or use corr2 :
corr2(a,b); % returns a scalar

I got scalar as output too. But if-loop is giving an error. The output should be between 1 and 2.

what if we have more than two images? I mean a sequence of images.
