Dear Colleagues,
I want to overlay several scans of films (same object, different exposures) which of course do not fit each other exactly. Each scan needs to be rotated a tiny little bit for a perfect fit. Is there any tool out there that can assist with this? ImageJ would be fine to rotate in sub-degree steps, but finding the right value is quite tedious. I think the problem can be squeezed in some sort of "minimizing the difference between the two images dependent on the rotation angle" algorithm. Before inventing the wheel twice, I thought I'd ask. Is there anything out there I could use?
The individual scans are greyscale, the desired result is a color image where each scan has its own color, so the differences can be easily spotted.
Thanks and best reagrds,
Wo
