[Insight-users] How to use the code in testing ? itkVoronoiSegmentationImageFilter

[Luis Ibanez]

Hi x0_y0_0,


This particular test is probably not a good exmple of how to use
the filter.


You can get rid of most of the code before line 88,


You just need:


   typedef itk::Image<unsigned short,2> UShortImage;
   typedef itk::Image<unsigned char,2>  PriorImage;
   typedef itk::VoronoiSegmentationImageFilter<
      UShortImage, UShortImage, PriorImage> VorSeg;

   VorSeg::Pointer testVorseg(VorSeg::New());

   typedef itk::ImageFileReader< UShoftImage > ReaderType;
   ReaderType::Pointer reader = ReaderType::New();

   reader->SetFileName( argv[1] );

   testVorseg->SetInput( reader->GetOutput() );
   testVorseg->SetMean(520);
   testVorseg->SetSTD(20);
   testVorseg->SetMeanTolerance(10);
   testVorseg->SetSTDTolerance(20);
   testVorseg->SetNumberOfSeeds(400);
   testVorseg->SetSteps(5);

   std::cout << "Running algorithm" << std::endl;
   testVorseg->Update();

   typedef itk::ImageFileWriter< UShoftImage > WriterType;
   WriterType::Pointer writer = WriterType::New();

   writer->SetFileName( argv[2] );

   writer->SetInput( testVorseg->GetOutput() );
   writer->Update();



   Regards,


      Luis
