i want to find the correlation cofficients for adjacent pixels in an image. i write this code and it give 2x2 matrix, now i don't know how to get horizantal, vertical and diagonal values for any image?
a=image;
a1=a(:,1:end-1);
a2=a(:,2:end);
cor=corrcoef(double(a1(:)),double(a2(:)));

I = im2double(imread('cameraman.tif'));
c_diag = corrcoef(I(1:end-1, 1:end-1), I(2:end, 2:end))
c_vert = corrcoef(I(1:end-1, :), I(2:end, :))
c_horz = corrcoef(I(:, 1:end-1, :), I(:, 2:end))

How are you draw this options ? for solution above
c_diag,c_vert and c_horz ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/330506/image.jpeg)

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