MATLAB: Displacement vector

Question

Hi, I have two images of same size such that

im1_o=image at time 0

im2_1=image at time 1

I want to compute displacement vetor for these two images using intensity correlation for given Window size (odd). I donot understand where to start. Can I use some builtin function of matlab? Any help or link to some code.

Answer 1

If you look at the cross correlation registration demo in the Image Processing Toolbox, you'll see how normxcorr2 can be used to solve for the displacement vector you are interested in.
