In a fraction of a second humans are able to comprehend novel images of objects and scenes. Indeed, the human represents the only existence proof that a general shape recognizer is even possible. Geon theory offers an account of this phenomenon characterized by four general assumptions: a) Objects are represented as an arrangement of simple convex or singly concave parts (geons), b) The geons can be distinguished by binary contrasts (differences) in viewpoint invariant properties, such as

Recent research evaluating these assumptions is reviewed.
