Here collected you will find a number of methods for solving certain kinds of "algebraic" problems found in vision and manipulation programs for our AMF arm and our TVC eye. They are collected here to avoid the need to ...

How does a person answer questions about children's stories? For example, consider 'Janet wanted Jack's paints. She looked at the picture he was painting and said 'Those paints make your picture look funny.' The ...

The GAS program is a display simulation of a 2 dimensional ideal gas. Barriers, or walls, are line segments, and molecules, alias particles or balls, are circles. Collisions occur between balls and other balls as well ...

A methodology is presented for generating descriptions of objects from line drawings. Using projection of planes, objects in a scene can be parsed and described at the same time. The descriptions are hierarchical, and lend ...

As originally proposed, perceptrons were machines that scanned a discrete retina and combined the data gathered in a linear fashion to make decisions about the figure presented on the retina. This paper considers differential ...

The Little Robot System provides for the I.T.S. user a medium size four degree of freedom six axis robot which is controlled by the PDP-6 computer through the programming language Lisp. The robot includes eight force ...

This proposal discusses practical aspects of our project to produce a replicable research tool for development of real-world computer-controlled hand-eye systems. If this proposal is read out of context, it will not seem ...

A LISP program has been written which returns the location of a vertex in a suspected region, as well as an indication of the certainty of success.

This paper descries D-SCRIPT, a language for representing knowledge in artificial intelligence programs. D-SCRIPT contains a powerful formalism for descriptions, which permits the representation of statements that are ...

A programming language for natural language processing programs is described. Examples of the output of programs written using it are given. The reasons for various design decisions are discussed. An actual session with ...

The film SOLAR CORONA was made from data taken from August 14, 1969 through May 7, 1970, by OSO-VI, one of the Orbiting Satellite Observatories. One of the experiments on board scanned across and up and down the image of ...

Pretty-printing is the conversion of the list structure to a readable format. This paper outlines the computational problems encountered in such a task and documents the current algorithm in use.

TC-SKELETON's duty is to help find the dimensions of brick shaped objects by searching for sets of three complete edges, on for each dimension. The program was originally written by Patrick Winston, and then was refined ...

This paper discusses the visual phenomenon of gloss. It is shown that the perception of this phenomenon derives from two effects (1) that the image reflected by a glossy surface lies in a different plane from the surface, ...

Results of scene analysis, as they are achieved, direct and advise the flow of subsequent processing.

This paper discusses the problem of context-free position estimation using a stereo vision system with moveable eyes. Exact and approximate equations are developed linking position to measureable quantities of the ...

The FINDSPACE problem is that of establishing a volume in space where an object of specified dimensions will fit. The problem seems to have two subproblems: the hypothesis generation problem of finding a likely spot to ...
