How to find the maximum point of correlation in matlab for two similar images..

I would like to know how to find the point which has the maximum correlation of two images. I already found out the program for correlation of two similar images . But now, i have to know the point at which the correlation is maximum.I have to add the command lines to find the maximum point of correlation. The program is:-

 Img1 = imread('C:\Users\DELL\Desktop\Natures\Nature1.jpg'); Img2 = imread('C:\Users\DELL\Desktop\Natures\Nature2.jpg');
 N = 500; 
range = 1:N; da = [0 20]; db = [30 30]; dc = [0 20]; dd = [30 30]; A=Img1(da(1) + range, da(2) + range); B=Img1(db(1) + range, db(2) + range); C=Img2(dc(1) + range, dc(2) + range); D=Img2(dd(1) + range, dd(2) + range);
X = normxcorr2(A, B); m = max(X(:)); [i,j] = find(X == m);
Y = normxcorr2(C, D); m = max(Y(:)); [k,l] = find(Y == m);
R = zeros(2*N, 2*N); R(N + range, N + range) = B; R(i + range, j + range) = A; R(N + range, N + range) = D; R(k + range, l + range) = C; figure subplot(2,2,1), imagesc(A) subplot(2,2,2), imagesc(B) subplot(2,2,3), imagesc(X) rectangle('Position', [j-1 i-1 2 2]), line([N j], [N i]) subplot(2,2,4), imagesc®;
subplot(2,2,1), imagesc(C) subplot(2,2,2), imagesc(D) subplot(2,2,3), imagesc(Y) rectangle('Position', [l-1 k-1 2 2]), line([N l], [N k]) subplot(2,2,4), imagesc(S); delta_orig1 = da - db %--> [30 10] delta_recovered = [i - N, j - N] %--> [30 10] delta_orig2 = dc - dd %--> [30 10] delta_recovered = [k - N, l - N] %--> [30 10]

Thank u very much for this answer. I would like to know further.. how to find the displacement across x and y direction and the difference in angle between them.. Would be of great use so that i can include that part to the program... Thank you in advance...
