1. A method for increasing the resolution of a depth or disparity map related to multi view video, the method comprising: deriving a high resolution depth or disparity map based on a low resolution depth or disparity map and a masked texture image edge map comprising information on edges, in a high resolution texture image, having a correspondence in the low resolution depth map, wherein the texture image and the depth map are associated with the same frame, and the low resolution depth map has a lower resolution than the texture image.
