[Insight-users] Extract the gradient information from CannyEdgeDetectionImageFilter

[ken]

Is there a way to extract the raw gradient information
$\sqrt(G_{x}^2+G_{y}^2+G_{z}^2)$ from the CannyEdgeDetectionImageFilter, or
I have to use itkGradientMagnitudeImageFilter in order to get those
information?

Thanks!
