Hi, I think the problem is that *because* they are screengrabs, hugin has
no information about lens, field of view (scale). [Aside, this might make a
good Turing test - are these images related?!]. I think if you told hugin
that the second image had a shorter focal length by the same ratio as the
scale difference between the images it could do it. A human can easily tell
that one picture is the same as the other except for scale and rotation,
but that is trickier for a computer to do it without human help. But I also
agree with you, that if you supply matching control points, the computer
should look for the best rotation/scale parameters. I do not know if Hugin
has this capability. There was a post about overlaying old pictures on new
ones, maybe that will help.
Alister.
