Claim Text:
1. A method for producing a high resolution depth or disparity map, the method comprising: obtaining a depth or disparity map associated with a frame; obtaining a texture image associated with said frame, wherein the depth or disparity map has a lower resolution than the texture image; generating, from the depth or disparity map, a first edge map identifying edges in the depth or disparity map; generating, from the obtained texture image, a second edge map identifying edges in the texture image, said edges in the texture image consisting of a first set of edges a second set of edges, wherein each edge included in the first set of edges corresponds to an edge identified by the first edge map and each edge included in the second set of edges does not correspond to any edge identified by the first edge map; masking the second edge map, generated from the obtained texture image, using the first edge map, generated from the depth or disparity map, to produce a masked texture image edge map that comprises the edges included in the first set of edges but does not comprise the edges included in the second set of edges; and deriving the high resolution depth or disparity map based on the depth or disparity map and the masked texture image edge map, wherein masking the second edge map using the first edge map to produce the masked texture image map comprises removing from the second edge map all edges identified by the second edge map that do not correspond to at least one the edges identified in the first edge map, thereby producing the masked texture image edge map.
