Theory of Handwriting
(1980-03-01)
Handwriting production is viewed as a constrained modulation of an underlying oscillatory process. Coupled oscillations in horizontal and vertical directions produce letter forms, and when superimposed on a rightward ...
The Image Irradiance Equation: Its Solution and Application
(1981-06-01)
How much information about the shape of an object can be inferred from its image? In particular, can the shape of an object be reconstructed by measuring the light it reflects from points on its surface? These questions ...
Local Rotational Symmetries
(1985-08-01)
This thesis describes a new representation for two-dimensional round regions called Local Rotational Symmetries. Local Rotational Symmetries are intended as a companion to Brady's Smoothed Local Symmetry Representation ...
A Model for Deliberation, Action, and Introspection
(1980-05-01)
This thesis investigates the problem of controlling or directing the reasoning and actions of a computer program. The basic approach explored is to view reasoning as a species of action, so that a program might apply ...
Inspection Methods in Programming
(1981-06-01)
The work reported here lies in the area of overlap between artificial intelligence software engineering. As research in artificial intelligence, it is a step towards a model of problem solving in the domain of ...
The Definition and Implementation of a Computer Programming Language Based on Constraints
(1980-08-01)
The constraint paradigm is a model of computation in which values are deduced whenever possible, under the limitation that deductions be local in a certain sense. One may visualize a constraint 'program' as a network ...
Foundations of Actor Semantics
(1981-05-01)
The actor message-passing model of concurrent computation has inspired new ideas in the areas of knowledge-based systems, programming languages and their semantics, and computer systems architecture. The model itself ...
A Multiple-Context Equality-Based Reasoning System
(1983-04-01)
Expert systems are too slow. This work attacks that problem by speeding up a useful system component that remembers facts and tracks down simple consequences. The redesigned component can assimilate new facts more ...
The Representation of Image Texture
(1981-09-01)
This thesis explores how to represent image texture in order to obtain information about the geometry and structure of surfaces, with particular emphasis on locating surface discontinuities. Theoretical and psychophysical ...
Implementation of a Theory of Edge Detection
(1980-04-01)
This report describes the implementation of a theory of edge detection, proposed by Marr and Hildreth (1979). According to this theory, the image is first processed independently through a set of different size filters, ...
