This paper describes the automatic selection of features from an image training set using the
theories of multidimensional discriminant analysis and the associated optimal linear …

The development of software that would be to image understanding systems what expert
system shells are to expert systems has been the subject of considerable enquiry over the …

We have been develo** a theory for the generic representation of 2-D shape, where
structural descriptions are derived from the shocks (singularities) of a curve evolution …

Few systems capable of recognizing complex objects with free-form (sculptured) surfaces
have been developed. The apparent lack of success is mainly due to the lack of a competent …

New digital systems for the processing of photogrammetric and remote sensing images have
led to new approaches to information extraction for map** and Geographic Information …

Object recognition systems constitute a deeply entrenched and omnipresent component of
modern intelligent systems. Research on object recognition algorithms has led to advances …

A survey of research in the area of vision sensor planning is presented. The problem can be
summarized as follows: given information about the environment as well as information …

We consider the use of medial surfaces to represent symmetries of 3-D objects. This allows
for a qualitative abstraction based on a directed acyclic graph of components and also a …

The authors present the assembly-plan-from-observation (APO) method for robot
programming. The APO method aims to build a system that has the capability of observing a …

We present an aspect-graph approach to 3D object recognition where the definition of an
aspect is motivated by its role in the subsequent recognition step. Specifically, we measure …
