[Insight-users] GradientRecursiveGaussianImageFilter

[joanna ZHU]

Hello, dear all.

I am trying to use GradientRecursiveGaussianImageFilter,  but there is
exception while running. I am thinking may be it is out of memory  since the
size of the image is 512*512*272.  I am wondering is there any other filters
that I could use instead of this one. Actually, I just want to use the
gradient vector of a few points. Is there a better way to calculate the
gradient vector. Thanks a lot.

Best Regards,

Joanna
