Abstract
A method and device for establishing a frontier between a first object and at least a second object of a scene in the space of a depth map, at least a part of the first object and at least a part of the at least a second object being visible from the point of view associated with the depth map through a set () of elements of the depth map. Thereafter, the method comprises comparing, for a point of the scene visible through a first element of said set, depth information associated with the point with depth information associated with said first element and with depth information associated with the other elements, called second elements; establishing a line representative of a direction associated with the frontier between the first object and the at least a second object from the comparison results; selecting a part of the vertices of surface elements visible through the set according to the orientation of normal associated with the vertices; and establishing the frontier from the coordinates of the selected vertices expressed in the space of the depth map.
