[Insight-users] Sparse or multislice registration

[Dan Mueller]

Hi Laura,

The following links may be useful:
    http://www.itk.org/Wiki/ITK_Release_4/Image_Class_Hierarchy_Refactoring
    (Requires developer access)
http://www.itk.org/mailman/private/insight-developers/2010-October/thread.html

These links detail a refactor of the image class hierarchy which would
support multi-slice images. Note that this is not yet implemented; I
believe the implementation is part of the ITKv4 activities. This
refactor would solve your issues, because a multi-slice image could
then be treated as a "normal" image and simply registered with the
existing registration framework.

Cheers, Dan

Maybe I'm wrong, but it looks like that the examples aren't suitable to solve my problems (all registrations seem to be between "similar" images).
