[Insight-developers] how to reuse a filter correctly

[Ivan Macia]

Hi Leila,

You should do something like this (just an example):

std::vector<ImageType::Pointer> outputs;

for( ... ) // your loop
{
   filter->SetInput( newInput ); // new input or parameters every time, in
any case this will call Modify() for the filter internally
   filter->Update();

   ImageType::Pointer newOutput = filter->GetOutput();
   newOutput->DisconnectPipeline();

   outputs.push_back( newOutput );
}


Hope that helps

Iván
