Hi Tobi,

Sorry that I didn't notice this post earlier. Hongjie Xie has some
excellent routines to do exactly what you want.

Go to this site

http://www.iamg.org/CGEditor/cg2003.htm

and do a search for this title

An IDL/ENVI implementation of the FFT-based algorithm for automatic
image registration

It will bring you to another link with source code and data files.

Dr. Xie's web site is at
