However, I do not see the NaNs that José saw when using float. José, can you try running your code again with pixel types as float using either the ITK test image or using another image that starts out as float (perhaps there is trouble reading in your vtk ushort image) to see if you get NaNs with these images as well? I do think there is a bug with the way shorts are handled in this filter, but I'm trying to determine whether your float NaNs are a separate bug or a related issue.<div><br></div><div>I used the following command to run the test code with various test images :</div><div>>> /path/to/build/ITK/bin/ITKGPUSmoothingTestDriver itkGPUDiscreteGaussianImageFilterTest /path/to/source/ITK/Examples/Data/BrainProtonDensitySlice.png /path/to/output/gpuGaussianImageFilterTest3DOutput.mha 3</div><div><br></div><div>-Kris<br><div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">I cannot follow this either.
