Model Order

The ``Model Order'' determines the order of the polynomial used to perform the registration warping. For instance, if the model order were three, a cubic polynomial would be used to model the warping.

Each model order above first has a required minimum number of GCPs. The minimum numbers of GCPs for each order from two to five are summarized below:

         Required GCPs                Order
               7                       2nd
              11                       3rd
              16                       4th
              22                       5th
