[Insight-users] Dilation several times

[Gaëtan Lehmann]

Hi Barbara,

You should try something like

   ImageType::Pointer img = previousFilter->GetOutput();
   for( int i=0; i<3; i++ )
     {
     dilate->SetInput( img );
     dilate->Update();
     img = dilate->GetOutput();
     img->DisconnectPipeline();
     }

Note that Richard Beare and I have also contributed some more efficient  
dilation/erosion/opening/closing filters to the insight journal. They  
should be more performant, and still let you use the pipeline architecture  
of ITK - that's not the case here.
