   I'll look it up from DemonsRegistration filter, thanks. Is suppose it's
hardcoded for Gaussian filter?
  Yes, I know this for Gaussian filter, it works in ND, and some others like
VectorGradientAnisotropicDiffusionFilter ...
  but  I'm interested in Bilateral and  TotalVariation filter in 3D.
  My interest arise from topic from my earlier post
http://old.nabble.com/Regularization-type-with-Demons-ts28852748.html#a28946676
  For now as a workaround I use NthElementImageAdaptor,
ImageRegionConstIterator, ImageRegionIterator to get components
  from deformation field smooth it with forementioned  ITK filters and
compose updated deformation field.

   I think I'll be interested in code you mention, and with little help
about coding guidelines and ITK as a whole, I'm interested to submitted back
to Insight Journal if possible according to above topic :)

Regards,
Miki
