What you want is a technique like the SIFT algorithm to identify similar
features in two images. I recommend the autopano-sift tools:
Also available is Autopano (which is a different program)
While you are looking at this, if you are interested in panoramas or
even just trying to make a larger image out of two overlapping scans,
you should also try Hugin
These tools can be used together to streamline panorama generation and
can be used to create fabulous (and massive) wide-angle images.
