[MINC-users] Blurring with noise and/or sharp edges

[Gabriel A. Devenyi]

Hi all,

I have some data I'd like to blur which has "nonsense" voxels outside the
brain (MP2RAGE maps). I want to exclude these voxels from the blur. If I
zero out these voxels I get an edge effect, the apodizing doesn't help as
much as I'd like it to.

Is anyone aware of an alternate blurring method which can avoid these
issues?

Thanks.
