Abstract : A system for obtaining a surface-based, three-dimensional description of a complex urban scene from a single image is described, and an example involving an aerial photograph is provided. The author's approach exploits task-specific knowledge involving block-shaped objects in an urban scene. First, linear connected structures in the image are generated; these are meant to represent building boundaries. Next, the two dimensional structures are converted into three dimensional wire frames. Finally, an approximate surface-based description of the scene is generated from the wire frames. The monocular analysis system is a component of the 3D Mosaic scene understanding system. (Author)
