[Insight-users] Gaussian filtering of tensor image

[Won-Ki Jeong]

Hi.. I am trying to apply a Gaussian filter on tensor volumes. I
defined the image type and filter as follows:

typedef itk::Image<DiffusionTensorPixelType, 3> TensorImageType;
typedef itk::DiscreteGaussianImageFilter<TensorImageType,
TensorImageType> GaussTensorFilterType;

For some reasons, this won't compile. The errors are something like,

c:\work\proj\insighttoolkit-2.8.1\code\common\itkNeighborhoodOperator.h(136)
: error C2039: 'RealType' : is not a member of 'itk::NumericTraits<T>'

and much more.

Does anyone know what causes this error? Thanks
