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.

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.

I guess you are looking for something at the end the page
Use 'quiver' function.
Thanks.

But the object is changing size (i.e. morphing) and so what you want is the new area defined by the flood. This is not a displacement vector as there is something completely new in the image. A displacement vector is the change in location of an object in BOTH images. So what you want to do is register the images to the best of your ability and then do an image comparison, such as a subtraction/area calculation/segmentation etc, to figure out how much has flooded. Post your images if you want better answers.
