[ITK] [ITK-users] Region Growing for huge data set

[Dženan Zukić]

Hi Abdelkhalek,

depending on the filters in your pipeline (whether all of them support
streaming), it might be useful to use StreamingImageFilter
<https://itk.org/Doxygen/html/classitk_1_1StreamingImageFilter.html>. If
not, you could have all intermediate results deallocated before starting
the main (most memory intensive) processing step:

ImageType::Pointer intermediate;
//open a block, so that all variables created in it are deallocated at the
end of it
{
//read image
//do some processing
lastFilterInThisBlock->Update();
intermediate=lastFilterInThisBlock->GetOutput();
}
//everything except intermediate will be deallocated at this point, freeing
memory
mainProcessingStep(intermediate);

Regards,
Dženan
