[Insight-users] Problems with Maurer Distance Transform

[Christian Werner]

Hi!

I need a nice DistanceTransformation function. Danielsson is fine but 
slooooow. Then I tried the SignedMaurerDistanceMapImageFilter which is 
quite fast. Unfortunately the results are quite different. It seems the 
DanielsonDistanceMapImageFilter yields better results. What am I doing 
wrong?

I am passing no input parameter to the filters, I just put them in the 
pipeline. Maybe I am missing important parameters? They are both used 
the exactly same way:

   ///// typedef typename itk::DanielssonDistanceMapImageFilter< 
ImageType, ImageType > FilterType;
   typedef typename itk::SignedMaurerDistanceMapImageFilter< ImageType, 
ImageType > FilterType;
   typename FilterType::Pointer filter = FilterType::New();
   filter->SetInput( itkImporter->GetOutput() );

Any idea?


Best regards,
Christian
