Work reported herein was conducted at the Artificial Intelligence Laboratory, a Massachusetts Institute of Technology research program supported by the Advanced Research Projects Agency of the Department of Defense, and was monitored by the Office of Naval Research under Contract Number N00014-70-A-0362-0002.The basic problem of this research is to find methods which will enable a program to construct a three dimensional interpretation from the line drawing of a scene, where the scene may have shadows and various degeneracies. These methods differ from those used in earlier related programs in that they use region information extensively, and include formalisms for eye and lighting position. The eventual result of this research will be a program which should be able to successfully treat scenes with far fewer restrictions than present programs will tolerate.MIT Artificial Intelligence Laboratory Vision Group
