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
