This paper briefly discusses the following questions: What are the benefits of special-purpose languages? When is a field ready for such a language? Are any parts of our current vision research ready?

A collection of LISP functions has been written to provide vidisector users with the following three line-oriented vision primitives: (i) given an initial point and an estimated initial direction, track a line in that ...

A descriptive formalism along with a philosophy for its use and expansion are presented wherein descriptions are of a highly structured nature. This descriptive system and the method of recognition are extended to the ...

Organization of knowledge requires the flexible use of hierarchy in descriptions. This memo attempts to catalog the issues related to recognizing and executing such descriptions, drawing examples primarily from the blocks world.

A collection of functions have been written to allow LISP users to record display calls in a disk file. This file can be UREAD into a small LISP to reproduce the display effects of the program without doing the required ...

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

This paper discusses three main problems associated with the control of the motion of a mechanical arm. 1) Transformation between different coordinate systems used to describe the state of the arm. 2) Calculation of ...

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, ...

This note is a collection of well known interesting facts about human vision. All parameters are approximate. Some may be wrong. There are sections on retina physiology, eye optics, light adaptation, psychological curios, ...

Some general properties of textures are discussed for a restricted class of textures. A program is described which inputs a scene using vidisector camera, discerns the texture elements, calculates values for a set of ...

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. ...
