[Insight-users] ApproximateSignedDistanceMapImageFilter exception

[Derek Magee]

This problem has been raised a couple of times before on the list, but I can't find any solution posted. I'm getting an error with ApproximateSignedDistanceMapImageFilter of the form:
itk::ExceptionObject (0012FC44)Location: "void __thiscall itk::MultiThreader::SingleMethodExecute(void)"File: .\itkMultiThreader.cxxLine: 368Description: itk::ERROR: MultiThreader(00BBD508): Exception occurred during SingleMethodExecute I'm using msvc2005 and ITK 3.0.1. Code is below (NB replacing ApproximateSignedDistanceMapImageFilter withSignedDanielssonDistanceMapImageFilter makes everything work ok). The volume is simply a synthetic 100x100x100 8-bit binary analyze volume with a single connected component.Any clues?
 
ThanksDerek Magee
