METHOD AND DEVICE FOR PROVIDING A LAYERED DEPTH MODEL OF A SCENE
First Claim
1. Method of providing (510) a layered depth model (605) of a scene, the layers of the depth model (605) 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, andthe 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 (SR) is located on that side of the respective depth transition which is depth-wise farthest away with respect to the primary viewing direction.

Abstract
The invention relates to a device and method of providing a layered depth model of a scene, the layers of the depth model comprising primary view information for a primary view of the scene from a primary viewing direction and occlusion information associated with the primary view information for use in rendering in 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 in formation comprises a safety region (SR1, SR2, SR3, SR4) 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 (SR1, SR2, SR3, SR4) is located on that side of the respective depth transition which is depth-wise farthest away with respect to the primary viewing direction. The invention further relates to a signal comprising a layered depth model of a scene as described above, as well as a computer program product implementing the method according to the invention.
