Dear All,

Can you please suggest SimpleITK examples for 3D (.mhd images) for registration whose transform supports Shift, Rotation and Scaling?

I am using the example below which supports Shift and Rotation.

Thanks,

Luis Gonçalves

Hello @Luis_Carlos_Carneiro,

Just use a [Similarity3DTransform](https://simpleitk.org/doxygen/latest/html/classitk_1_1simple_1_1Similarity3DTransform.html) as the optimized transform (composition of isotropic scaling and rigid transformation) or use an [AffineTransform](https://simpleitk.org/doxygen/latest/html/classitk_1_1simple_1_1AffineTransform.html) if your scaling is non-isotropic.
