Representation and Recognition of the Spatial Organization of Three Dimensional Shapes
(1977-05-01)
The human visual process can be studied by examining the computational problems associated with deriving useful information from retinal images. In this paper, we apply this approach to the problem of representing ...
Light Source Effects
(1977-05-01)
The perception of surface luster in achromatic single view images seems to depend on the existence of regions with source-like properties. These regions are due to the interaction of specular component of the surface's ...
A System for Representing and Using Real-World Knowledge
(1977-12-01)
This report describes a knowledge-base system in which the information is stored in a network of small parallel processing elements ??de and link units ??ich are controlled by an external serial computer. This network ...
The Competence/Performance Dichotomy in Programming
(1977-01-01)
We consider the problem of automating some of the duties of programmers. We take as our point of departure the claim that data management has been automated to the point where the programmer concerned only about the ...
Overlays: A Theory of Modelling for Computer Aided Instruction
(1977-02-01)
Overlay modelling is a technique for describing a student's problem solving skills in terms of modular program designed to be an expert for the given domain. The model is an overlay on the expert program in that it consists ...
The FRL Primer
(1977-07-01)
The Frame Representation Language (FRL) is an experimental language written to explore the use of frames as a knowledge representation technique. The term 'frame' as used in FRL was inspired by Minsky's [75] development ...
NUDGE, A Knowledge-Based Scheduling Program
(1977-02-01)
Traditional scheduling algorithms (using the techniques of PERT charts, decision analysis or operations research) require well-defined quantitative, complete sets of constraints. They are insufficient for scheduling ...
The FRL Manual
(1977-09-01)
The Frame Representation Language (FRL) is described. FRL is an adjunct to LISP which implements several representation techniques suggested by Minsky's [75] concept of a frame: defaults, constraints, inheritance, procedural ...
Dual Coding and the Representation of Letter Strings
(1977-07-01)
Sub-strings derived from four-letter strings (e.g. ABCD) were presented to subjects using a variation on Bransford and Franks' (1971) paradigm. Each strins was in either upper or lower case. Subjects were then tested ...
Dynamics of a Three Degree of Freedom Kinematic Chain
(1977-10-01)
In order to be able to design a control system for high-speed control of mechanical manipulators, it is necessary to understand properly their dynamics. Here we present an analysis of a detailed model of a three-link ...
