Split Brain Mask

Split the brain into three parts (hemispheres + cerebellum)

Description

This procedure aims at splitting the two hemispheres and at removing the cerebellum and a part of brain stem in order to give access to the internal and low faces of the cortex.
An erosion is applied to a mask of white matter in order to split it at the levels of corpus callosum and pons. This operation provides 3 seeds corresponding to the two hemispheres and cerebellum. Then, these seeds grow first inside white matter and finally throughout grey matter in order to recover the hemisphere shapes.
