On Visual Detection of Light Sources
(1975-05-01)
The paper addresses the following problem: Given an array of light intensities obtained from some scene, find the light sources in the original scene. The following factors are discussed from the point of view of their ...
Control, Multiple Description, and Purpose in the Visual Perception of Complex Scenes: A Pogress Report
(MIT Artificial Intelligence Laboratory, 1975-08)
This memo describes a vision program for recognizing simple furniture comprising assemblies of blocks, in which the same item may be composed in diverse ways. As such, it is concerned with three theoretical issues, perceptual ...
Hypothesis Formation and Evaluation in Medical Diagnosis
(1975-01-01)
This thesis describes some aspects of a computer system for doing medical diagnosis in the specialized field of kidney disease. Because such a system faces the spectre of combinatorial explosion, this discussion concentrates ...
Qualitative and Quantitative Knowledge in Classical Mechanics
(1975-12-01)
This thesis investigates what knowledge is necessary to solve mechanics problems. A program NEWTON is described which understands and solves problems in mechanics mini-world of objects moving on surfaces. Facts and ...
Notes Relating to the Design of a High Quality Image Sensor
(MIT Artificial Intelligence Laboratory, 1975-06)
Some of the information that as used in arriving at a design for a high quality image input device is documented. The device uses a PIN photo-diode directly coupled to an FET-input op-amp as the sensor and two moving-iron ...
The Evolution of Procedural Knowledge
(MIT Artificial Intelligence Laboratory, 1975-01-16)
A focus on planning and debugging procedures underlies the enhanced proficiency of recent programs which solve problems and acquire new skills. By describing complex procedures as constituents of evolutionary sequences of ...
Ideas About Management of LISP Data Bases
(MIT Artificial Intelligence Laboratory, 1975-01)
The trend toward larger data bases in A.I. programs makes it desirable to provide program support for the activity of building and maintaining LISP data bases. Many techniques can be drawn from present and proposed systems ...
Representing the Semantics of Natural Language as Constraint Expressions
(MIT Artificial Intelligence Laboratory, 1975-01)
The issue of how to represent the "meaning" of an utterance is central to the problem of computer understanding of natural language. Rather than relying on ad-hoc structures or forcing the complexities of natural language ...
Kinematics, Statics, and Dynamics of Two-D Manipulators
(MIT Artificial Intelligence Laboratory, 1975-06)
In order to get some feeling for the kinematics, statics, and dynamics of manipulators, it is useful to separate the problem of visualizing linkages in three-space from the basic mechanics. The general-purpose two-dimensional ...
The Facts of Light
(MIT Artificial Intelligence Laboratory, 1975-05)
This is a random collection of facts about radiant and luminous energy. Some of this information may be useful in the design of photo-diode image sensors, in the set-up of lighting for television microscopes and the ...
