Difference in mutual information due to color.

MI(this:obs, this:model)-MI(this:obs, other:model)

the stored model color information from the other face is compared with the observation colors of *this face. It is assumed that there is no intersection of the two pixel sets.

The other face has been constructed on the current image and so its model data reflects the current intensity statistics outside *this observation region
