[Insight-users] How to disconnect a pipeline

[Martin Styner]

Hi everybody
I have a question in regard to the itk pipeline system.
In some cases my pipeline has grown too large so that I run out of 
memory. Now I want to separate as nicely as possible the pipeline into 2 
separate parts.
The 'nicest' I could so far come up with is the following:

Before:

FilterB->SetInput(FilterA->GetOutput());
FilterC->SetInput(FilterB->GetOutput());

After:

FilterB->SetInput(FilterA->GetOutput());
FilterB->Update();
ImageOutB = FilterB->GetOutput();
ImageOutB->DisconnectPipeline();
FilterA->Delete();
// Can't do a FilterB->Delete(), otherwise ImageOutB iscorrupted ?
FilterC->SetInput(ImageOutB);

Is there maybe an easy way to create a Duplicate of an image, this would 
solve the whole business.

Regards
Martin
