[Insight-users] image spacing unit and anisotropic diffusion image filter

[Feng Ma]

Hi,

  I have a quick question about anisotrpic diffusion image filter: does the 
image spacing measurement unit matter? e.g., will the result different if I 
use millimeter or micro as image spacing unit?

  From software guide, I knew that for Gaussian smoothing, the sigma should 
be in millimeter. I think that will require image spacing to use millmeter 
also. Is that correct?

  Thanks.
