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

Tue Jan 7 13:22:02 EST 2014

Andras and Luis,
  Thanks for your suggestions. I have tried running the code in 64-bit
Release mode. Using print/cout statements I found out that the code crashes
at the same point as the Debug mode. I have 8GB RAM on my laptop and 'am
using a cropped image to test this filter (dimensions: 66x66x7). Is 7
slices too large? Or is this a bug in the filter?

Thanks
Prashanth
