Paper Abstract

The computation and interpretation of visible parts of objets in a scene is one the most important tasks in imagery. Hidden part removal algorithms are often used to solve this problem in synthetic imagery, but these algorithms are not adapted to recognition tasks because they do not provide a representation of visibility and (its dual) occlusion. In this paper we propose to take into account the representation of occlusion by a high-level description of tridimensional scenes. The idea is that the knowledge of a view point introduces occluding relations between objects in the scene. We use a graph based approach, and we define an "occluding graph" for a viewpoint position. The use of this graph simplifies applications like hidden part removal, image interpretation, and obstacle avoidance.
