Abstract
A method is provided for processing a depth map for subsequent transmission. Depth regions in the depth map are identified, each of the depth regions defining a portion of the depth map. Ranges of depth values are determined for the depth regions and are further transmitted with the depth map. The ranges of depth values provide segmentation information of the depth regions in the depth map.
Claims21
A method comprising:
- obtaining a depth map of a scene, wherein the depth map comprises a plurality of depth values;
- defining a plurality of cells in the depth map, wherein each cell of the plurality of cells corresponds to a portion of the depth map;
- identifying at least one depth regions in each of the plurality of the cells;
- determining at least one ranges of depth values for the at least one depth regions;
- and
- transmitting the depth map and the at least one ranges of depth values.

A method comprising:
- receiving at least one images and at least one depth maps of a scene;
- receiving at least one ranges of depth values,
- wherein the at least one depth maps comprises a first depth map,
- wherein the first depth map comprises a plurality of cells,
- wherein the plurality of cells comprise the at least one at least one depth maps comprises the at least one ranges of depth values,
- wherein each of the at least one ranges of depth values corresponds to at least one depth regions of a first depth map,
- wherein the at least one depth maps comprises a first depth map,
- wherein each cell of the plurality of cells corresponds to a portion of the first depth map;
- and
- processing the first depth map using the at least one ranges of depth values for each cell, together with at least one of the images, to synthesize an image at the target viewpoint.
