Knowledge-Directed Interpretation of Engineering Drawings

Abstract

It was noted in Chapter 1 that the interpretation of images of line drawings might usefully be thought of as an example of a knowledge-based image understanding problem. Knowledge-based vision or image interpretation systems seek to apply a priori knowledge to segment the input image(s) into regions corresponding to objects or constructs of interest in the domain at hand, providing as rich a description of those objects and/or constructs as the available knowledge allows. Despite the obvious relevance of work in this area, review of the relevant literature shows a clear distinction between attempts to improve the commercial state of the art in line drawing interpretation and more general research into image understanding systems.
