Vision Utilities

Abstract

This paper documents a collection of Lisp utilities which I have written while doing vision programming on a Symbolics Lisp machine. Many of these functions are useful both as interactive commands invoked from the Lisp Listener and as "building blocks" for constructing larger programs. Utilities documented here include functions for loading, storing, and displaying images, for creating synthetic images, for convolving and processing arrays, for making histograms, and for plotting data.
