XP. A Common Lisp Pretty Printing System
(1989-03-01)
XP provides efficient and flexible support for pretty printing in Common Lisp. Its single greatest advantage is that it allows the full benefits of pretty printing to be obtained when printing data structures, as well ...

A Theory of Networks for Appxoimation and Learning
(1989-07-01)
Learning an input-output mapping from a set of examples, of the type that many neural networks have been constructed to perform, can be regarded as synthesizing an approximation of a multi-dimensional function, that ...
Direct Computation of 3D Shape Invariants and the Focus of Expansion
(1989-05-01)
Structure from motion often refers to the computation of 3D structure from a matched sequence of images. However, a depth map of a surface is difficult to compute and may not be a good representation for storage and ...
The Perceptual Buildup of Three-Dimensional Structure from Motion
(1989-08-01)
We present psychophysical experiments that measure the accuracy of perceived 3D structure derived from relative image motion. The experiments are motivated by Ullman's incremental rigidity scheme, which builds up 3D ...
Computer Perception of Three-Dimensional Objects
(1989-08-01)
We first pose the following problem: to develop a program which takes line-drawings as input and constructs three-dimensional objects as output, such that the output objects are the same as the ones we see when we ...
Stimulus Familiarity Determines Recognition Strategy for Novel 3-D Objects
(1989-07-01)
We describe a psychophysical investigation of the effects of object complexity and familiarity on the variation of recognition time and recognition accuracy over different views of novel 3D objects. Our findings indicate ...
Taxonomic Syntax for First-Order Inference
(1989-06-01)
Most knowledge representation languages are based on classes and taxonomic relationships between classes. Taxonomic hierarchies without defaults or exceptions are semantically equivalent to a collection of formulas ...
Compiling Scientific Code Using Partial Evaluation
(1989-07-01)
Scientists are faced with a dilemma: either they can write abstract programs that express their understanding of a problem, but which do not execute efficiently; or they can write programs that computers can execute ...
Recognition by Linear Combinations of Models
(1989-08-01)
Visual object recognition requires the matching of an image with a set of models stored in memory. In this paper we propose an approach to recognition in which a 3-D object is represented by the linear combination of 2-D ...
