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;
}
I use try/catch, but I can not catch the exception, just access
violation when m_DeformableMesh3Dfilter->Update()..
Can some give me a hand?
Thanks a lot!!!
