[ITK] [ITK-users] 3D registration - teeth image

[Timothee Evain]

Hi Oscar,

The error you are receiving means that your images don't overlap with the initial transformation in the physical space. 
You have to set a better transformation initialization.
You should take a look to the itk CenteredTransformInitializer ( https://itk.org/Doxygen/html/classitk_1_1CenteredTransformInitializer.html#a3284b1aabf2690889aa7435676fc7893 ), or the versor version of it, if you're using a transform with versor for rotation.
This will help setting a good starting position.

HTH,

Tim

Hi guys 

I have to register two 3D images of teeth (screenshots attached). 
I tested several approaches, such as: affine registration, rigid registration, 
mattes and mean square metric, etc. 
When I use moments centering I get an error (Too many samples map outside moving 
image buffer) and when I use geometric centering I do not get error, but the result (resampler) 
is exactly the same moving image. Any sugestions 

Thank you so much 
Oscar
