Finding Components on a Circuit Board

Abstract

This paper describes a set of programs written in LISP that recognize resistors on circuit boards. The approach leans heavily on a thorough examination of the features found in representative intensity arrays and on representing the important points procedurally. The programs attempt to exploit evidence as it is gathered. The issues of hypothesis formation and change are considered. This paper represents a continuation of research described in a S. B. thesis of the same title submitted at M.I.T. on June, 1973.
