Hi all,

     I wrote the following code:

 

   m_stiff[0] = 0.00001;
   m_stiff[1] = 0.04;
   m_scale[0] = 1;
   m_scale[1] = 1;
   m_scale[2] =1;
 
m_BinaryMask3DMeshSource->SetBinaryImage(m_CastImageFilter->GetOutput())
;
m_BinaryMask3DMeshSource->SetObjectValue(200); 
 
m_GradientMapFilter->SetInput(gradientMagnitudeFilter->GetOutput());
m_GradientMapFilter->SetSigma(1.0);
m_GradientMapFilter->Update();
 
m_DeformableMesh3DFilter->SetStiffness(m_stiff);
m_DeformableMesh3DFilter->SetTimeStep(0.2);
m_DeformableMesh3DFilter->SetStepThreshold(10);
m_DeformableMesh3DFilter->SetScale(m_scale);
m_DeformableMesh3DFilter->SetGradientMagnitude(0.8);
 
m_DeformableMesh3DFilter->SetGradient(m_GradientMapFilter->GetOutput());
m_DeformableMesh3DFilter->SetInput(m_BinaryMask3DMeshSource->GetOutput()
);
 
try
{
        m_DeformableMesh3DFilter->Update();//At this point, access
violation
}
catch(itk::ExceptionObject & excep)
{
        std::cerr << "Exception Caught!"<<std::endl;
}

  although I use try/catch, but I can not catch the exception, just
access violation.

 

Can some give me a hand?

Thanks a lot!!!
