Description and Theoretical Analysis (Using Schemata) of Planner: A Language for Proving Theorems and Manipulating Models in a Robot
(1972-04-01)
Planner is a formalism for proving theorems and manipulating models in a robot. The formalism is built out of a number of problem-solving primitives together with a hierarchical multiprocess backtrack control structure. ...
Visual Feedback in a Coordinated Hand-Eye System
(MIT Artificial Intelligence Laboratory, 1972-08)
A system is proposed for the development of new techniques for the control and monitoring of a mechanical arm-hand. The use of visual feedback is seen to provide new interactive capabilities in a machine hand-eye system. ...
An Approach to Three-Dimensional Decomposition and Description of Polyhedra
(MIT Artificial Intelligence Laboratory, 1972-07)
This paper presents a description methodology for trihedral planar solids that, as in Roberts' approach, decomposes an object into simpler components. The present approach, however, is more sophisticated and results in a ...
Shedding Light on Shadows
(MIT Artificial Intelligence Laboratory, 1972-06)
This paper describes methods which allow a program to analyze and interpret a variety of scenes made up of polyhedra with trihedral vertices. Scenes may contain shadows, accidental edge alignments, and some missing lines. ...
VISHEM: A bag of "robotics" formulae
(MIT Artificial Intelligence Laboratory, 1972-12)
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 ...
The Projective Approach to Object Description
(MIT Artificial Intelligence Laboratory, 1972-12-15)
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 ...
Summary of Selected Vision Topics
(MIT Artificial Intelligence Laboratory, 1972-07)
This is an introduction to some of the MIT AI vision work of the last few years. The topics discussed are 1) Waltz's work on line drawing semantics, 2) heterarchy, 3) the ancient learning business and 4) copying scenes. ...
Recognition of Real Objects
(MIT Artificial Intelligence Laboratory, 1972-10)
High level semantic knowledge will be employed in the development of a machine vision program flexible enough to deal with a class of "everyday objects" in varied environments.
This report is in the nature of a thesis ...
Analytical differentiation by computer using a Symmetrical List Processor
(1972)
The Symmetrical List Processor SLIP; developed by Professor Joseph Weizenbaum of MIT, was implemented with considerable modifications and additions on the University of Cape Town computer. A package to perform automated ...
Generating Semantic Description from Drawings of Scenes with Shadows
(MIT Artificial Intelligence Laboratory, 1972-11)
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 and ...
