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 ...
Descriptive Simulation: Combining Symbolic and Numerical Methods in the Analysis of Chemical Reaction Mechanisms
(1989-09-01)
The Kineticist's Workbench is a computer program currently under development whose purpose is to help chemists understand, analyze, and simplify complex chemical reaction mechanisms. This paper discusses one module ...
The Bifurcation Interpreter: A Step Towards the Automatic Analysis of Dynamical Systems
(1989-09-01)
The Bifurcation Interpreter is a computer program that autonomously explores the steady-state orbits of one-parameter families of periodically- driven oscillators. To report its findings, the Interpreter generates ...
A Self-Organizing Multiple-View Representation of 3D Objects
(1989-08-01)
We explore representation of 3D objects in which several distinct 2D views are stored for each object. We demonstrate the ability of a two-layer network of thresholded summation units to support such representations. Using ...
A Comparison of Hardware Implementations for Low-Level Vision Algorithms
(1989-11-01)
Early and intermediate vision algorithms, such as smoothing and discontinuity detection, are often implemented on general-purpose serial, and more recently, parallel computers. Special-purpose hardware implementations ...
