Hi Pedro,
Interesting question, just to make sure it is clear,
If you want an affine 2D transform, then your matrix will be 3x3 instead of
4x4 isn't it?
Take a look at the inheritance diagram of the itkTransform class, (doxygen
documentation) and on the Affine branch you will find
itkCenteredAffineTransformation.
I was also looking or a Polar to Cartesian conversion but didn't find
anything, there is the Versor Transform, but appearently is rigid.
Hope that helps
