The Description of Large Systems
(1984-09-01)
In this paper we discuss the problems associated with the description and manipulation of large systems when their sources are not maintained as single fields. We show why and how tools that address these issues, such ...
Computational Experiments with a Feature Based Stereo Algorithm
(1984-01-01)
Computational models of the human stereo system can provide insight into general information processing constraints that apply to any stereo system, either artificial or biological. In 1977, Marr and Poggio proposed ...
On Edge Detection
(1984-08-01)
Edge detection is the process that attempts to characterize the intensity changes in the image in terms of the physical processes that have originated them. A critical, intermediate goal of edge detection is the detection ...
The Find-Path Problem in the Plane
(1984-02-01)
This paper presents a fast heuristic algorithm for planning collision-free paths of a moving robot in a cluttered planar workspace. The algorithm is based on describing the free space between the obstacles as a network ...
Diagnostic Reasoning Based on Structure and Behavior
(1984-06-01)
We describe a system that reasons from first principles, i.e., using knowledge of structure and behavior. The system has been implemented and tested on several examples in the domain of troubleshooting digital electronic ...
Selecting One Among the Many: A Simple Network Implementing Shifts in Selective Visual Attention
(1984-01-01)
This study addresses the question of how simple networks can account for a variety of phenomena associated with the shift of a specialized processing focus across the visual scene. We address in particular aspects of ...
Basic Solid Mechanics for Tactile Sensing
(1984-03-01)
In order to stably grasp objects without using object models, tactile feedback from the fingers is sometimes necessary. This feedback can be used to adjust grasping forces to prevent a part form slipping from a hand. ...
Determining Grasp Points Using Photometric Stereo and the PRISM Binocular Stereo System
(1984-08-01)
This paper describes a system which locates and grasps doughnut shaped parts from a pile. The system uses photometric stereo and binocular stereo as vision input tools. Photometric stereo is used to make surface ...
Routing Thoughts
(MIT Artificial Intelligence Laboratory, 1984-05)
In a parallel machine with many thousands of processors the routing of information between processors is a key task, which turns out to require as much hardware and perhaps more sophistication than local computing itself. ...
The Role of Intensional and Extensional Representations in Simulation
(MIT Artificial Intelligence Laboratory, 1984-12)
I review three systems which do simulation in different domains. I observe the following commonality in the representations underlying the simulations:
• The representations used for individuals tend to be domain-dependent. ...
