This is outside my area of expertise, so all I can say is that these sorts of programs do exist, but restricting yourself to Python libraries may make your life unnecessarily hard. On a separate topic, you're posting through Google Groups with its abhorrent bugs. Can you please either edit your posts before sending (removing the blank lines, wrapping to a sane width, and trimming the quoted text), or switch to a better newsreader (or the mailing list)? You'll find that a lot of people here either filter your message to /dev/null automatically, or take one look and just move on to the next post.

For my purpose, the images won't have to be 'perfectly' matched, but hopefully as close as possible. Registration algorithms won't work for this reason--the images aren't identical to each other because of the different perspectives. -- https://mail.python.org/mailman/listinfo/python-list

That's hard - very hard. I suggest you find a stand-alone program that will do that part of the job; it'll be easier than finding a Python library for it.
