Hi,

in order to visualize small structures segmented with level-sets, I would
like to extract the exact surface position with subpixel accuracy. Can
anybody tell me

1) which interpolation makes sense (linear, cubic, higher order, ...)
2) how I can achive such an interpolation in an efficient manner.


Thank you very much for your help!


Regards,
Nils
