Either

  • by showing the two layers (layer groups) next to each other, with control points connected by lines (as suggested by Volker), similar to the elephant example in https://ch.mathworks.com/discovery/image-registration.html, or
  • by showing the difference between two images diff_img = np.abs(img1 - img2) (this only works for images from the same modality/contrast range, though)

Another idea is to compute the optical flow between the two images and plot a vector/displacement field.
