Abstract

This paper addresses the problem of distinguishing straight lines from curves in noisy gray tone images, and mathematically representing those lines and curves. A method for locating comers is discussed as well as criteria, based on spline representations, for classifying line segments as straight or curved. Results are given for several typical noisy engineering line drawings.
