An intriguing candidate theory, whose full consideration is beyond the scope of the present note, is the involvement of a common principle in the visual system s quest for invariance. The object specific mechanisms would provide better tolerance to translation than to rotation in depth, because of the generally smaller changes in object appearance under the former transformation.

Encoding objects by their similarities to a few reference shapes or prototypes results in a representation that is appealingly low dimensional and therefore easy to learn. Familiar object views can still be useful if storing them improves the performance of the interpolating mechanism of their object. Representation is representation of similarity . Recognizing an image as a view of some object then becomes the problem of deciding the membership of that image in the class of all views of that object, which we call its view space.
