the code c++ is :
#if defined(_MSC_VER)
#pragma warning ( disable : 4786 )

#include "itkHessian3DToVesselnessMeasureImageFilter.h"

int main( int argc, char *argv[] )
{

 if( argc < 3 )
    {
    std::cerr << "Usage: inputImage outputImage [sigma] [alpha_1] [alpha_2]" << std::endl;
    }
  
  const     unsigned int        Dimension       = 3;
  typedef   double              InputPixelType;

                            VesselnessMeasureFilterType::New();

  ReaderType::Pointer   reader = ReaderType::New();
  WriterType::Pointer   writer = WriterType::New();
  
  reader->SetFileName( argv[1] );
  hessianFilter->SetInput( reader->GetOutput() );
  if( argc >= 4 )
    {
    hessianFilter->SetSigma( static_cast< double >(atof(argv[3])) );
    }
  vesselnessFilter->SetInput( hessianFilter->GetOutput() );
  writer->SetInput( vesselnessFilter->GetOutput() );
  writer->SetFileName( argv[2] );
  if( argc >= 5 )
    {
    vesselnessFilter->SetAlpha1( static_cast< double >(atof(argv[4])));
    }
  if( argc >= 6 )
    {
    vesselnessFilter->SetAlpha2( static_cast< double >(atof(argv[5])));
    }

  writer->Update();
  return EXIT_SUCCESS;
}

    
I'm testing the vesselness filter on an MRA image .

The last picture was what I expected except for the crash. If you post
you code I will take a look at this.
