p386fig11.21 A simulation of the Craik-O'Brien-Cornsweet Effect when viewed on a planar surface in depth.<BR>||  Craik-O'Brien-Cornsweet Effect.  Can the model simulate other surface percepts? eg surface brightness.  The 2D surface with the image on it is viewed at a very near depth.  Adapts (Grossberg, Todovoric 1988) to 3D.  [V1 binocular boundaries -> V2 initial boundaries -> V2 final boundaries -> V4 surface] cart [very near, near, fixation plane, far, very far]
