Document Summary
Shine flashlight on eye and first it would detect edges. Then two other processes would happen to identify and separate the geons on this object. Identified by the concavities: b) (whe looking at concavities) detecting non accidental properties (naps) Viewpoint invariance: na can be seen whatever the view (can recognize the object from. Invariant edge properties different edge properties of each shape different viewpoints) Rarely are an objects naps not visible. If we can recognize its geons we can recognize the object. Gestault principles will help with this process: produce structural description.
