Time-Sharing LISP for the PDP-6
(1968-03-01)
This memo written in the style and convention of A.I. memo No. 116A, may be considered an addendum thereto. It should prove to be a welcome updating on the LISP system.
Some Aspects of Pattern Recognition by Computer
(1967-02-01)
A computer may gather a lot of information from its environment in an optical or graphical manner. A scene, as seen for instance from a TV camera or a picture, can be transformed into a symbolic description of points ...
A Quick Fail-Safe Procedure for Determining Whether the GCD of 2 Polynomials is 1
(1967-03-01)
One of the most widely used routines in an algebraic manipulation system is a polynomial manipulation package (1,2,3). The crucial operation in such routines is the extraction of the Greatest Common Divisor (GCD) of ...
Estimating Stereo Disparities
(1967-02-01)
An interesting practical and theoretical problem is putting bounds on how much computation one needs to find the stereo-disparity between two narrow-angle stereo scenes. By narrow angle I mean situations wherein the angle ...
Incorporating MIDAS Routines into PDP-6 LISP
(1967-03-01)
Some PDP6 LISP users have felt a need for a way to incorporate MIDAS subroutines into LISP. LISP has been changed to let you do this, using files found on the LISP SYSTEM microtape. You write a routine for LISP in much the ...
Remarks on Correlation Tracking
(1967-03-01)
The problem is to track the motion of part of a field of view. Let us assume that the scene is a two-dimensional picture in a plane perpendicular to the roll axis. (these simplifying assumptions, of course, are a main ...
CHAR PLOT
(1967-03-01)
CHAR PLOT is a routine which enables one to use the CalComp plotter as a versatile output device. It is presently available as CHPLOT BIN (English CHAR PLOT) on tape MS 3. The program CHAR PLOT is normally called by a PUSHJ ...
Hardware and Program Memo About SERVO
(1967-03-01)
SERVO is intended as an engineering and programming analyzing and debugging aid for use with devices connected through the input and output multiplexers to the PDP-6. Cannel numbers and values to output, as well as ...
Computer Tracking of Eye Motions
(1967-03-01)
This memo is to explain why the Artificial Intelligence group of Project MAC is developing methods for on-line tracking of human eye movements. It also gives a brief resume of results to date and the next steps.
Natural Language Input for a Computer Problem Solving System
(1964-03-01)
This paper describes a computer program which accepts and "understands" a comfortable, but restricted set of one natural language, English. Certain difficulties are inherent in this problem of making a machine "understand" ...
