[Insight-users] Re: MRIBiasCorrection

[Luis Ibanez]

Hi Alma,

Yes, this mask is a binary image. The mask is intended to
eliminate pixels that have partial volume effects.

They are assumed to be the pixels in the edges of anatomical
structures; therefore the mask is expected to be close to a
edge-map of the image, eventually dilated a bit to have a
margin of security.


You may want to read the "README" file that is found in
the same directory of this application, as well as the
papers:

Where this method is described.
