Stereo Feature Matching in Disparity Space
(1989-09-01)
This paper describes a new method for matching, validating, and disambiguating features for stereo vision. It is based on the Marr-Poggio- Grimson stereo matching algorithm which uses zero-crossing contours in ...
Consensus Knowledge Acquisition
(1989-12-01)
We have developed a method and prototype program for assisting two experts in their attempts to construct a single, consensus knowledge base. We show that consensus building can be effectively facilitated by a debugging ...
How to Do the Right Thing
(1989-10-01)
This paper presents a novel approach to the problem of action selection for an autonomous agent. An agent is viewed as a collection of competence modules. Action selection is modeled as an emergent property of an ...
Optimization of Series Expressions: Part I: User's Manual for the Series Macro Package
(1989-01-01)
The benefits of programming in a functional style are well known. In particular, algorithms that are expressed as compositions of functions operating on series/vectors/streams of data elements are much easier to understand ...
Computational Structure of the N-body Problem
(1988-04-01)
This work considers the organization and performance of computations on parallel computers of tree algorithms for the N-body problem where the number of particles is on the order of a million. The N-body problem is ...
Exploiting Lexical Regularities in Designing Natural Language Systems
(1988-04-01)
This paper presents the lexical component of the START Question Answering system developed at the MIT Artificial Intelligence Laboratory. START is able to interpret correctly a wide range of semantic relationships associated ...
Intelligent Assistance for Program Recognition, Design, Optimization, and Debugging
(1989-01-01)
A recognition assistant will help reconstruct the design of a program, given only its source code. A design assistant will assist a programmer by detecting errors and inconsistencies in his design choices and by ...
On the Sensitivity of the Hough Transform for Object Recognition
(1988-05-01)
A common method for finding an object's pose is the generalized Hough transform, which accumulates evidence for possible coordinate transformations in a parameter space and takes large clusters of similar transformations ...
Modeling Robot Flexibility for Endpoint Force Control
(1988-05-01)
Dynamic models have been developed in an attempt to match the response of a robot arm. The experimental data show rigid-body and five resonant modes. The frequency response and pole-zero arrays for various models of ...
The Performance of a Mechanical Design 'Compiler'
(1989-01-01)
A mechanical design "compiler" has been developed which, given an appropriate schematic, specifications, and utility function for a mechanical design, returns catalog numbers for an optimal implementation. The compiler ...
