Document Summary

If you know how to define a concept, you can identify anything that is in that concept. 3) interior angles sum to 180 degrees. But features we use are not always conserved. Object perception is characterized by a range of invariances. Some images look similar, but some represent different things. Remember individual view of things and transform them in our mind to match current input (or vice versa) We may remember a number of views of an object, and then perform a mental rotation to match. View invariance does not occur for novel objects. We recognize things by combinations of primitive features. All objects are composed of geometric primitives - geons. Objects are built of geons and their particular arrangement and attachment. If you obscure part of an image: Easier to recognize if the geons can still be extracted. Harder to recognize if geons are degraded. Human object perception probably relies on both systems.
