Abstract: Various implementations are directed to providing inter-layer dependency information. In one implementation, syntax elements are generated that indicate an inter-layer dependency structure among three-dimensional video (3DV) layers. Based on the inter-layer dependency structure, an inter-layer reference is identified for a picture from a layer of the 3DV layers. The picture is encoded based, at least in part, on the inter-layer reference. Corresponding decoding implementations are also provided. Additionally, in another implementation, a transmission priority and an indication of network congestion are used to determine whether to transmit data for a particular 3DV layer. The transmission priority is based on an inter-layer dependency structure among multiple 3DV layers. Another implementation is directed to a network abstraction layer unit that can explicitly identify and convey inter-layer references and corresponding dependencies.

Abstract: Several implementations relate to depth map coding. In one implementation, a depth coding rate, that results from coding one or more portions of a depth map using a particular coding mode, is determined. The depth map can be used to render video for a different view than that of the depth map. A depth map distortion, that results from coding the one or more portions of the depth map using the particular coding mode, is determined. A value of distortion for the rendered video, based on the depth map distortion and on a particular relationship between the depth map distortion and values of distortion for the rendered video, is determined. It is determined whether to use the particular coding mode to code the one or more portions of the depth map, and the determination is based on the value of distortion for the rendered video and the depth coding rate.

Abstract: A method interpolates and filters a depth image with reduced resolution to recover a high resolution depth image using edge information, wherein each depth image includes an array of pixels at locations and wherein each pixel has a depth. The reduced depth image is first up-sampled, interpolating the missing positions by repeating the nearest-neighboring depth value. Next, a moving window is applied to the pixels in the up-sampled depth image. The window covers a set of pixels centred at each pixel. The pixels covered by the window are selected according to their relative position to the edge, and only pixels that are within the same side of the edge of the centre pixel are used for the filtering procedure. A single representative depth from the set of selected pixel in the window is assigned to the pixel to produce a processed depth image.

Abstract: An image for a virtual view of a scene is generated based on a set of texture images and a corresponding set of depth images acquired of the scene. A set of candidate depth values associated with each pixel of a selected image is determined. For each candidate depth value, a cost that estimates a synthesis quality of the virtual image is determined. The candidate depth value with a least cost is selected to produce an optimal depth value for the pixel. Then, the virtual image is synthesized based on the optimal depth value of each pixel and the texture images.

Abstract: Several implementations relate, for example, to depth encoding and/or filtering for 3D video (3DV) coding formats. A sparse dyadic mode for partitioning macroblocks (MBs) along edges in a depth map is provided as well as techniques for trilateral (or bilateral) filtering of depth maps that may include adaptive selection between filters sensitive to changes in video intensity and/or changes in depth. One implementation partitions a depth picture, and then refines the partitions based on a corresponding image picture. Another implementation filters a portion of a depth picture based on values for a range of pixels in the portion. For a given pixel in the portion that is being filtered, the filter weights a value of a particular pixel in the range by a weight that is based on one or more of location distance, depth difference, and image difference.
