The recovery and understanding of a line drawing from indoor scenes
Marco Straforini, C. Coelho, M. Campani, Vincent Torre · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1992
A general procedure for the understanding of a class of indoor scenes is proposed. The suggested algorithm makes use of an extensive 2-D processing of the image that provides a faithful line drawing of the viewed scene. It also uses procedures adequate for the understanding of the 3-D structure and for the recognition of several items in the scene. The approach is specific for indoor scenes, such as corridors, offices, and laboratory rooms, where long straight edges are predominant and vanishing points can be detected.>
