METHOD AND DEVICE FOR PROVIDING MULTILAYER DEPTH MODEL OF SCENE AND SIGNAL CONTAINING MULTILAYER DEPTH MODEL OF SCENE Russian patent published in 2014 - IPC G06T15/20 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a method and a device for providing a multilayer depth model of a three-dimensional scene. The method of providing a multilayer model comprising primary view information for a primary view of the scene from a primary viewing direction (PVD) and occlusion information associated with the primary view information for use in rendering other views of the scene, wherein the primary view information comprises layer segments of the model which are depth-wise closest with respect to the primary viewing direction, and the occlusion information comprises further layer segments of the model and wherein the occlusion information comprises a safety region (SR) adjacent to a depth transition for which occlusion information is provided (J1, J2, J3, J4), and wherein the safety region comprises corresponding segments of the primary view information, and wherein the safety region is located on that side of the respective depth transition which is depth-wise furthest with respect to the primary viewing direction.

EFFECT: reduced artefacts resulting from reduction of the multilayer depth model.
