Interpreting pictures of polyhedral scenes
Alan K. Mackworth · International Joint Conference on Artificial Intelligence · 1973
A computer program that achieves the interpretation of line drawings as polyhedral scenes without using specific object prototypes is described. The method is primarily based on general coherence rules that the orientations of the surfaces and edges must satisfy, thereby dispensing with predetermined interpretations of particular categories of picture junctions as corners. The paper also comments on the relationship of this program to four other scene analysis programs.
