Interpreting Line Drawings as Three-Dimensional Surfaces

Classics

We propose a computational model for interpreting line drawings as three dimensional surfaces, based on constraints on local surface orientation along extremal and discontinuity boundaries. Specific techniques are described for two key processes: recovering the three-dimensional conformation of a space curve (e.g., a surface boundary) from its two-dimensional projection in an image, and interpolating smooth surfaces from orientation constraints along extremal boundaries.In Hayes, J.
