class itk::SmoothVectorFieldFilter< TScalarType, NumberImageDimensions, NumberVectorDimensions >

Abstract base class that takes a vector field as input and smoothes it.

As of 16/01/2010, I have extended this to cope with time varying vector fields. The previous version of this class, only did 2D or 3D. This will do N/M-dimensional. However, be aware that for example, you can have N=2 dimensional vectors, and M=3 dimensional images. So, if N != M, then do you really want to try smoothing? It might be better to set the sigma to zero if you don't wan't smoothing in all dimensions.

As of 16/01/2010, also note, that we now extend InPlaceImageFilter. This is because with time varying velocity fields, on decent size images, you need a lot of memory. So, rather than have an input/output buffer, we use one buffer. But this filter defaults to OFF to minimise impact on other programs that are not using time varying velocity fields. Obviously, you need some memory to perform the smoothing, so each subclass should clear references as soon as its done.
