Unfolding An Indoor Origami World

In this work, we present a method for single-view reasoning about 3D surfaces and their relationships. We propose the use of midlevel constraints for 3D scene understanding in the form of convex and concave edges and introduce a generic framework capable of incorporating these and other constraints. Our method takes a variety of cues and uses them to infer a consistent interpretation of the scene. We demonstrate improvements over the state-of-the art and produce interpretations of the scene that link large planar surfaces.
