Abstract

Method and arrangement for increasing the resolution of a depth or disparity map related to multi view video. The method comprises deriving a high resolution depth map based on a low resolution depth map and a masked texture image edge map. The masked texture image edge map comprises information on edges in a high resolution texture image, which edges have a correspondence in the low resolution depth map. The texture image and the depth map are associated with the same frame.
