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.

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 ...

LIBPMK is a C++ implementation of Grauman and Darrell's pyramid match algorithm. This toolkit provides a flexible framework with which developers can quickly match sets of image features and run experiments. LIBPMK provides ...

This paper presents a solution to the problem of determining the distribution of an absorbing substance inside a non-opaque non-scattering body from images or ray samplings. It simultaneously solves the problem of determining ...

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 ...

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 ...

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. ...

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 ...

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. ...

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. ...

A program called LPTSEE has been written for use with the MIT vision system. LPTSEE makes use of the overprint capability of the line printer to allow the user to output a stored picture image.

The stored picture facility (FAKETV) allows LISP users, and to some extent machine language users, to access a library of stored images rather than live vidisector scenes. The vidisector functions in LISP have been slightly ...

This paper discusses some recent changes and additions to the vision system. Among the additions are the ability to use visual feedback when trying to acurately position an object and the ability to use the arm as a sensory ...

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 image-space, ...

The basic problem of this research is to find methods which will enable a program to construct a three dimensional interpretation from the line drawing of a scene, where the scene may have shadows and various degeneracies. ...

The VIRGIN program will interpret pictures of simple scenes. This paper describes a program, SINNER, which will deal with picture which contain cracks and shadows. In addition to handling pictures of this richer world, ...

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 ...

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 ...

The eye-hand robot at the Artificial Intelligence Laboratory now possesses the ability to occasionally copy simple configurations of blocks, using spare parts about whose presence it knows. One problem with which it cannot ...

This paper briefly describes the processing performed in the course of producing a line drawing from vidisector information.
