Grey/White classification
This procedure yields a grey/white classification of each hemisphere for people wishing to test the influence of classification algorithms (SPM, MNI's tools, SHFJ's tools...) on the final VBM result.
The proposed method deals with each hemisphere individually, in order to prevent mixing between the two internal faces or between low cortex faces and cerebellum, during the spatial smoothing performed before statistics.
Another feature of the proposed approach: we have decided to discard cerebellum because partial volume effects are in our opinion too important to reach a correct binary classification (a fuzzy classification might overcome this problem).
