Abstract
Line drawings provide an effective means of communication about the geometry of 3-D objects. An understanding of how to duplicate the way humans interpret line drawings is extremely important in enabling man-machine communication with respect to images, diagrams, and spatial constructs. In particular, such an understanding could be used to provide the human with the capability to create a line-drawing sketch of a polyhedral object that the machine can automatically convert into the intended 3-D model.
A recently published paper cite:Marill91 presented a simple optimization procedure supposedly able to duplicate human judgment in recovering the 3-D ``wire frame'' geometry of objects depicted in line drawings. Marill provided some impressive examples, but no theoretical justification for his approach. In this paper we introduce our own work by first critically examining Marill's algorithm.
