[Insight-users] Gradient of Vector Image

[Bing Jian]

Hi, Here is a question about gradient image.

Suppose I have a vector image which is obtained from
the output of gradientfilter applied on a scalar 3D
image. Now the dimension of vector is 3. Can I take
this vector image as input to the gradientfilter again?
My expected output image should be a 3d vector image.
And here the dimension of the vector should be 3*3=9,
as the Jacobian of the original gradient image.

Thanks in advance!
