[ITK-users] Restrict parameters of a transformation to be optimized during registration

[Marc-Michel Rohé]

Hello,

I am working with the registration pipeline of ITK using 3D images. What 
I would like to do is to register two images with translations but 
keeping the translation with respect to the third dimension at 0 (so 
find the best 2D translation on the axis X and Y mapping two images).

Is there a way to use the ITK classes "itkTranslationTransform" and 
"itkImageRegistrationMethodv4" ?

I have looked at multiple examples and documentation but could not find 
a way to do it easily if not coding a whole new class that performs 2D 
transform in 3D...

Thx !
