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 ...
A Heterarchical Program for Recognition of Polyhedra
(MIT Artificial Intelligence Laboratory, 1972-06)
Recognition of polyhedra by a heterarchical program is presented. The program is based on the strategy of recognizing objects step by step, at each time making use of the previous results. At each stage, the most obvious ...
Assigning Hierarchical Descriptions to Visual Assemblies of Blocks with Occlusion
(MIT Artificial Intelligence Laboratory, 1975-10)
This memo describes a program for parsing simple two-dimensional piles of blocks into plausible nested subassemblies. Each subassembly must be one of a few types known to the program, such as stack, tower, or arch. Each ...
One System for Two Tasks: A Commonsense Algorithm Memory that Solves Problems and Comprehends Language
(MIT Artificial Intelligence Laboratory, 1975-11)
Plan synthesis and language comprehension, or more generally, the act of discovering how one perception relates to others, are two sides of the same coin, because they both rely on a knowledge of cause and effect - algorithmic ...
The Intersection Problem
(MIT Artificial Intelligence Laboratory, 1975-11)
This paper is intended as a supplement to AI MEMO 331, "A System for Representing and Using Real-World Knowledge". It is an attempt to redefine and clarify what I now believe the central theme of the research to be. Briefly, ...
Computer Detection of Bent Fingers in Lead Bonding Frames
(MIT Artificial Intelligence Laboratory, 1976-01)
In the production of logic circuits in dual inline packages, various tedious assembly line tasks are performed by human operators using microscopes or television enlargements. One boring and difficult task is the detection ...
Garbage Collection in a Very Large Address Space
(MIT Artificial Intelligence Laboratory, 1975-09)
The address space is broken into areas that can be garbage collected separately. An area is analogous to a file on current systems. Each process has a local computation area for its stack and temporary storage that is ...
On Solving The Findspace Problem, or How to Find Out Where Things Aren't ....
(MIT Artificial Intelligence Laboratory, 1973-03-29)
A Knowledge-Based Computer Animation System
(MIT Artificial Intelligence Laboratory, 1976-02)
This paper reproduces part of a doctoral thesis proposal describing the design of a system capable of generating animated drawings in response to a simple story. The representation and interaction of the various sources ...
Knowledge Driven Recognition of the Human Body
(MIT Artificial Intelligence Laboratory, 1976-01)
This paper shows how a good internal model of the subject viewed aids in the visual recognition and following of key parts. The role of knowledge driven top-down tools and methods is shown by recognizing a series of human ...
