Is there any 3D differentials operations in ImageJ

[周鑫]

Hello All,

Is there any 3D differentials operations in ImageJ ?

I know that 2D differentials is usually  sqrt(dx*dx, dy*dy) and atan2(dy,dx)

But in 3D, information in Z can requires interpolation, as the voxel can be not cubic.

So is there any function has taken into account this effort?

Regards, Xin
