The Binford-Horn LINE-FINDER
This paper briefly describes the processing performed in the course of producing a line drawing from an image obtained through an image dissector camera. The edge-marking pahse uses a non-linear parallel line-follower. Complicated statistical measures are not used. The line and vertex generating phases use a number of heuristics to guide the transition from edge-fragments to cleaned up line-drawing. Higher-level understanding of the blocks-world is not used. Sample line-drawings produced by the program are included.
