Relating Images, Concepts, and Words.
Abstract
Examination of verbal descriptions of objects suggests that we use hierarchical structures for shape description; the highest levels of the hierarchy provide a general object framework or breakdown into component parts, and a description of each part by analogy to a well-understood set of shapes called 'prototypes'. Lower levels of the hierarchy provide refinement of the analogies and ways in which shapes deviate from the prototypes. The set of prototypes on which the analogies are based contains many common objects, especially natural objects and the parts of the human body, plus certain shapes with special symmetry properties. It is argued that no single 3-D representation scheme is natural for all members of this set of prototypes, and that since unfamiliar objects are described with respect to the basic set of shapes, these objects will have varying shape representation schemes also.
