Interpretation of imperfect line data as a three-dimensional scene

Abstract

This paper describes a heuristic scene description system called INTERPRET. This system accepts as input a scene represented as a line drawing. Based on a set of known object models the program attempts to determine the identity and location of each object viewed. INTERPRET uses knowledge about the world in a variety of ways to produce a description of the scene that is consistent with its input. The most significant feature of the system is its ability to deal with imperfect input data. This ability appears essential in light of our current stock of preprocessing technique and the variation that is possible in real world data.
