[Insight-users] Smoothing with a Mask Image

[Albert Huang]

Thanks for the suggestion Gaetan.

I guess I could do so but it'd be a pain to have to interpolate
the 0 points between two 1 (e.g. _ _ _ _ 1 _ _ 1 1 1 1 _ _)
with 3D inputs. I guess there isn't any sort of a ROI filter
or something like that available.

Hi,

Can't you just create a new image with the boundary value outside the
mask, and apply a smoothing filter on it ?
