I got this working by overriding my own interpolation function.  I 
guess this was the way to go?    I am now trying out various optimizers 
to adjust my parameters.  I am having a tough time matching the 
floating image from the fixed.  I would like to try the conjugate 
gradient technique but keep getting the ARMIJO condition unable to be 
met.  Has anyone tried registration on Satellite imagery?  If so, is 
there any suggestions you can give for the best methods to use?

Thank you


Take care
