fitgeotrans function for fitting geometric transformation to control
point pairs
The toolbox includes a new function, fitgeotrans, that takes pairs of control points
and uses them to infer a geometric transformation. The function returns a geometric
transformation object that can be used with imwarp.
imregister and imregtform Return Different Values
Some changes to the implementation of the imregister and imregtform functions might
cause these functions to return different results than they did before R2013b.
Compatibility Considerations
You might need to change parameters to the imregister and imregtform functions to
achieve similar results to what you had previously.
