[Insight-users] itkGradientRecursiveGaussianImageFilter

[Ting Chen]

did anybody try to use this filter in their work. It seems to me that this filter do not work correctly.
 
I run the itkGradientRecursiveGaussianImageFiltertest program using its default input. (a 8*8*8 image with a 4*4*4 cubic in it) the output is:
it seems the output in z direction do make some sense, however in x and y direction I cannot see any clue, can anyone solve this as soon as possible?
thanks
