[ITK-users] Problem with GPUNeighborhoodOperator

[Pedro Morais]

Hi all,

I'm testing the gpu version of the neighborhood operator
(itkGPUNeighborhoodOperatorImageFilter) to perform a gaussian derivative of
a 3D image.  I started by running the test example provided in ITK (
itkGPUNeighborhoodOperatorImageFilterTest.cxx) and it worked perfectly for
the default parameters. However, I simply changed the SetDirection option
from '0' to '1' (line 65, 'oper->SetDirection(1)'), and the result is a
blank image (all zeros). I have created a similar pipeline but using the CPU
version and it worked. 

Does anyone has an idea of what error is? Does itk-GPU allows the
application of these filters in directions other than zero?

Thanks in advance.

Best Regards,
Pedro
