Anisotropy in all directions

[oleg-kachan]

It would be nice to have anisotropy in all directions, not only along the axes.

For n-dimensional image it could be parameterized by an n x n matrix defining the ellipsoid, instead of n numbers as it is done right now.

Hi Oleg! Could you tell me a bit more about your use case? I am not confident yet, but I think this would require a different algorithm. The current algorithm really benefits from the axis alignment of the image and anisotropy. Are there other libraries out there or papers describing this kind of modification?
