[Insight-users] Smooth Vector Image

[Miller, James V (Research)]

You can use the VectorNeighborhoodOperatorImageFilter using a 
GaussianOperator.

Since the GaussianOperator is separable, you will either need
to cascade a number of VectorNeighborhoodOperatorImageFilters 
(one per dimension) or use a loop.  For the latter, you can look
at the code in Code/Algorithms/itkPDEDeformableRegistrationFilter.txx,
specifically the method 
PDEDeformableRegistrationFilter::SmoothDeformationField()

You can also enter a feature request on our bug-tracker requesting 
a Gaussian smooth filter for vector fields.

You might also want to look the
Code/BasicFilters/itkVectorGradientAnisotropicDiffusionImageFilter.

Hi there,

    Is there any efficient way to smooth a vector-valued image? 
DiscreteGaussianImageFilter does not accept vector valued image
as input.  :-(
   Many thanks in advance!
