[Insight-users] 3D mask in itk::GradientMagnitudeImageFilter

[Stian Dalene Gjedrem]

Hello all,

in the ITK Software Guide there is a description of the mask that is used
when a gradient image is computed from a 2D image.

My question is: what does the mask look like in 3D cases? Is the same mask
used in all directions (x,y,z) or are differents masks, one for each
dimension, used?

Thanks in advance for any help!

Best regards,
Stian D. Gjedrem
