[ITK Community] [Insight-users] itk AnisotropicDiffusion VesselEnhancement ImageFilter crashes

[Prashanth]

Luis,
  Thanks for the response. I ran the code in Debug mode.

Here's the error message: Unhandled exception in
itkAnisotropicDiffusionVesselEnhancementImageFilterTest.exe. Access
violation reading location.

And, here's the output from the call stack.

itkAnisotropicDiffusionVesselEnhancementImageFilterTest.exe!itk::
*NeighborhoodAccessorFunctor*<itk::Image<itk::DiffusionTensor3D<double>,3>
>::*Get*(const itk::DiffusionTensor3D<double> * pixelPointer) Line 68

It looks like a memory access violation error. I'm running ITK 4.4 and 'am
using the example dataset that the authors provide. Any pointers on how to
proceed further?

Thanks again
Prashanth
