Figure Boundary Description Routings for the PDP-6sVision Project

Abstract

As a step in the direction of "computer vision," several programs have been written which transform the output of a vidisector into some mathematical descriptions of the boundaries enclosing the objects in the field of view. Most of the discussion concerns the techniques used to transform a sequence of points, presumably representing a curve in the two-dimensional plane of view, into the best-fit conic-curve segment, or best-fit straight line. The resultant output of this stage is a list of such segments, one list for each boundary found.
