deployment of CAPE (computer-aided parts estimating system), a highly advanced knowledge-based system designed to generate, evaluate, and cost automotive part manufacturing plans. cape is engineered on an innovative, extensible, declarative processplanning and estimating knowledge representation language, which underpins the cape kernel architecture. Many manufacturing processes have been model...

Many objects have component parts, and these parts often differ in their visual salience. In this paper we present a theory of part salience. The theory builds on the minima rule for defining part boundaries. According to this rule, human vision defines part boundaries at negative minima of curvature on silhouettes, and along negative minima of the principal curvatures on surfaces. We propose t...

We propose that, for the task of object recognition, the visual system decomposes shapes into parts, that it does so using a rule defining part boundaries rather than part shapes, that the rule exploits a uniformity of nature-transver-sal@, and that parts with their descriptions and spatial relations provide a first index into a memory of shapes. This rule allows an explanation of several visua...

We present an approach to function-based object recognition that reasons about the functional-ity of an object's intuitive parts. We extend the popular \recognition by parts" shape recognition framework to support \recognition by functional parts", by combining a set of functional primitives and their relations with a set of abstract volumetric shape primitives and their relations. Previous app...

Part-based representations have been shown to be very useful for image classification. Learning part-based models is often viewed as a two-stage problem. First, a collection of informative parts is discovered, using heuristics that promote part distinctiveness and diversity, and then classifiers are trained on the vector of part responses. In this paper we unify the two stages and learn the ima...

Partonomies, such as body parts, like taxonomies, such as the animal kingdom, are hierarchical organizations of knowledge based on an asymmetric, transitive relation, part of or kind of. This article reports exploratory work on children's partonomic knowledge, and the relation between partonomic knowledge and use of taxonomic organization. Because parts are elements of both appearance and funct...

How do we think about the space of bodies? Several accounts of mental representations of bodies were addressed in body part verification tasks. An imagery account predicts shorter times to larger parts (e.g., back < hand). A part distinctiveness account predicts shorter times to more discontinuous parts (e.g., arm < chest). Apart significance account predicts shorter times to parts that are per...
