Learning by Creating and Justifying Transfer Frames
(1978-01-01)
In the particular kind of learning discussed in this paper, the teacher names a destination and a source. In the sentence, "Robbie is like a fox," Robbie is the destination and fox is the source. The student, on analyzing ...
An Overview of a Theory of Syntactic Recognition for Natural Language
(1979-07-01)
Assume that the syntax of natural language can be parsed by a left-to-right deterministic mechanism without facilities for parallelism or backup. It will be shown that this "determinism" hypothesis, explored within the ...
Specifying and Proving Properties of Guardians for Distributed Systems
(1979-06-01)
In a distributed system where many processors are connected by a networ and communicate using message passing, many users can be allowed to access the same facilities. A public utility is usually an expensive or limited ...
An Application of the Photometric Stereo Method
(1979-08-01)
The orientation of patches on the surface of an object can be determined from multiple images taken with different illuminations, but from the same viewing position. This method, referred to as photometric stereo, can ...
Computer Aided Evolutionary Design for Software Engineering
(1979-01-01)
We report on a partially implemented interactive computer aided design tool for software engineering. A distinguishing characteristic of our project is its concern for the evolutionary character of software systems. ...
Evidence for a Fifth, Smaller Channel in Early Human Vision
(1979-08-01)
Recent studies in psychophysics and neurophysiology suggest that the human visual system utilizes a range of different size or spatial frequency tuned mechanisms in its processing of visual information. It has been ...
Using Enhanced Spherical Images for Object Representation
(1979-05-01)
The processes involved in vision, manipulation, and spatial reasoning depend greatly on the particular representation of three-dimensional objects used. A novel representation, based on concepts of differential geometry, ...
SEQUINS and QUILLS: Representations for Surface Topography
(1979-05-01)
The shape of a continuous surface can be represented by a collection of surface normals. These normals are like a porcupine's quills. Equivalently, one can use the surface patches on which these normals rest. These ...
Creation of Computer Animation from Story Descriptions
(1979-08-01)
This report describes a computer system that creates simple computer animation in response to high-level, vague, and incomplete descriptions of films. It makes its films by collecting and evaluating suggestions from ...
Generating Semantic Descriptions From Drawings of Scenes With Shadows
(1972-11-01)
The research reported here concerns the principles used to automatically generate three-dimensional representations from line drawings of scenes. The computer programs involved look at scenes which consist of polyhedra ...
