Abstract:

Methods are presented 1 to partition or decompose a visual scene into the bodies forming it 2 to position these bodies in three-dimensional space, by combining two scenes that make a stereoscopic pair 3 to find the regions or zones of a visual scene that belong to its background 4 to carry out the isolation of objects in 1 when the input has inaccuracies. Running computer programs implement the methods, and many examples illustrate their behavior. The input is a two-dimensional line-drawing of the scene, assumed to contain three-dimensional bodies possessing flat faces polyhedra some of them may be partially occluded. Suggestions are made for extending the work to curved objects. Some comparisons are made with human visual perception. The main conclusion is that it is possible to sseparate a picture or scene into the constituent objects exclusively in basis of monocular geometric properties in basis of pure form in fact, successful methods are shown.
