[Insight-users] ApproximateSignedDistanceMapImageFilter

[Juan Carlos Prieto]

Hello Luis and ITK Users

I'm trying to use the ApproximateSignedDistanceMapImageFilter.
As described in the documentation it says the output has to be of type
float, When this is done, i get an exception :

/builddir/build/BUILD/InsightToolkit-3.16.0/Code/Common/itkMultiThreader.cxx:475:

itk::ERROR: MultiThreader(0x9a3d050):

Exception occurred during SingleMethodExecute

/usr/include/InsightToolkit/Algorithms/itkIsoContourDistanceImageFilter.txx:339:

itk::ERROR: IsoContourDistanceImageFilter(0x9a97d28): Gradient norm is lower
than pixel precision

On the other hand I tried with the same type of my input image (UShort) and
it worked but the output image is not as expected.



Please need some help
