Hi.  I have a collection of GCP .pts files from previously done image to image registration, probably about 50, and I would like to independently extrapolate the transformation polynomial coefficients from each .pts file.  The only way I've found to do this is to load two image files, then restore the GCP points from file, then re-save the coefficients to file.  Is there a way to automate this process without the unecessary steps of opening two image files?  Once the GCPs are found the transformation polynomial is calculated independent of which image files are open.  If there is not already some option in place to automate this GCP -> coefficients process would it be possible for you to reference me to the algorithm you use to determine the polynomial coefficients so I can write my own script?
