Progress in Extending the VIRGIN Program
Work reported herein was conducted at the Artificial Intelligence Laboratory, a Massachusetts Institute of Technology research program supported in part by the Advanced Research Projects Agency of the Department of Defense and monitored by the Office of Naval Research under Contract Number N00014-70-A-0362-0002.
Working Paper
The VIRGIN program will interpret pictures of simple scenes. This paper describes a program, SINNER, which will deal with picture which contain cracks and shadows. In addition to handling pictures of this richer world, SINNER employs heuristics which use knowledge about the structure of the three dimensional world to reduce the number of interpretations of some pictures and to augment the efficiency of the parsing process.
