GUI window to manually register two images?

Hi!

I need to make the simplest possible interactive window to achieve the following - I have two images (one is grayscale, the other one is contour lines), and I need to align them manually via shifts, scale change, and rotations.

I currently do the alignment in an external image editor and have a way to figure out the registration transformation after, but it would be really nice to be able to do it within MATLAB. Basically, I want a MATLAB GUI that is something like a 2-layer image, so I can use my mouse to move, scale and rotate one of the layers manually (similar to what one can do to a selection in an image editor). What would be the simplest way (using App designer or anything else) to achieve that?

You can try the registrationEstimator app included with the Image Processing Toolbox.
