[Insight-users] how to set the itkOnePlusOneEvolutionaryOptimizer?

[Luis Ibanez]

Hi Lanlanny,

You will find multiple examples on how to set the scaling
of the transform parameters in the ITK Software Guide


    http://www.itk.org/ItkSoftwareGuide.pdf

Chapter 8. pdf-page 241-340.

The source code for examples in this chapter can be found
in the directory

        Insight/Examples/Registation

The rule of thumb for the parameter scaling is to use 1.0
for the parameters related to rotation, and use 1/L for
the parameters related to translation.


Where

       L = diagonal of the image measured in physical units
           and multiplied by the magic factor 10.0.



for the settings of the OnePlusOne evolutionary optimizer
you may want to look at the example.
