[Insight-users] How to apply itkMRFimageFilter on a 4D vector image?

[Luis Ibanez]

Hi Chen,

Please let us know what arguments you are passing to the methods:

mrfFilter->SetMRFNeighborhoodWeight( std::vector<double> BetaMatrix );

and

mrfFilter->SetNeighborhoodRadius(const NeighborhoodRadiusType &);


They must be consistent with the 4D dimensionality of the image.


      Thanks


              Luis
