Hi,
Have you take a look into the classes.
If they have a threadedGenerateData, they are already multi-threaded.
If not they are threadable.

Hello
I have a problem about multi-thread. In my code use SURF to detect keypoint
and use KeyPointSetsMatchingFilter to matching its.
I want to know how can I use
ImageToSURFKeyPointSetFilter<http://www.orfeo-toolbox.org/doxygen/otbImageToSURFKeyPointSetFilter_8h_source.html>
and
KeyPointSetsMatchingFilter<http://www.orfeo-toolbox.org/doxygen/otbKeyPointSetsMatchingFilter_8h_source.html>
with
multi-threads.
typedef otb::ImageToSIFTKeyPointSetFilter<ImageType, PointSetType>
ImageToSIFTKeyPointSetFilterType;
ImageToSURFKeyPointSetFilterType::Pointer filter1 =
ImageToSURFKeyPointSetFilterType::New();
ImageToSURFKeyPointSetFilterType::Pointer filter2 =
ImageToSURFKeyPointSetFilterType::New();
filter1->SetInput(fixedReader->GetOutput());
filter1->SetOctavesNumber(octaves);
filter1->SetScalesNumber(scales);
filter1->SetNumberOfThreads(6);
filter2->SetInput(movingReader->GetOutput());
filter2->SetOctavesNumber(octaves);
filter2->SetScalesNumber(scales);
filter2->SetNumberOfThreads(1);
euclideanMatcher->SetInput1(filter1->GetOutput());
euclideanMatcher->SetInput2(filter2->GetOutput());
euclideanMatcher->SetDistanceThreshold(secondOrderThreshold);
euclideanMatcher->SetUseBackMatching(useBackMatching);
euclideanMatcher->Update();
Thank for suggestion.
