A question about itk filter multithread.
When I use a filter, how can I know where this filter class turn on multithread.
such as itkSimilarityIndexImageFilter, does it turn on the multithread when
using FilterType = itk::SimilarityIndexImageFilter<Image1Type, Image2Type>; FilterType::Pointer filter = FilterType::New(); ?
Does the filter turn on multithreading in the constructor when it is declared?
Another question, how can i set the number of threads and work units in my filter.
filter->GetNumberOfWorkUnits() and filter->GetMultiThreader()->GetMaximumNumberOfThreads(). There is also a Set version of both methods.
Most filters set up multithreading in the constructor. The rest are not easily threaded.
