[Insight-users] repeated dilation

[Karthik Krishnan]

To do this, you need to disconnect the DataObject from the pipeline 
before reusing it as input.
For instance:

dilater->SetInput( image );
image = dilater->GetOutput();
dilater->Update();
// Do whatever you want to do with the image

for( int i = 0; i < NumberOfRecursiveDilations-1; i++ )
{
  image->DisconnectPipeline(); 
  dilater->SetInput( image );
  image = dilater->GetOutput();
  dilater->Update();
  // Do whatever you want to do with the image
}
