Image correlation / matching / alignment

3 views (last 30 days)
Hello everybody,
I have 2 similar images, but taken with 2 different cameras, so the intensity may vary, also small displacement may be presented.
Could you please suggest me, what are the best functions or algorithms can be used to match/correlate/ align 2 similar images with different intensity and small displacement.
I've heard about following functions: imregister() and imregtform(). Are the they suitable to do what I want, and is there anything else I need to know?
Best Regards, Ivan

Yes. Give them a try.

For simple translations you can use normxcorr2() - demo attached. But it's not as good as the two you mentioned for cases where there is more complicated movement.

I'd also check out imregcorr for the case of simple transformations up through similarly transformations.
