    Abstract: Methods of encoding and decoding immersive video are provided. In an encoding method, source video data comprising a plurality of source views is encoded into a video bitstream. At least one of the source views is down-sampled prior to encoding. A metadata bitstream associated with the video stream comprises metadata describing a configuration of the down-sampling, to assist a decoder to decode the video bitstream. It is believed that the use of down-sampled views may help to reduce coding artifacts, compared with a patch-based encoding approach. Also provided are an encoder and a decoder for immersive video, and an immersive video bitstream.

    Abstract: An apparatus is arranged to generate a triangle mesh for a three dimensional image. The apparatus includes a depth map source (101) which provides a depth map and a tree generator (105) generates a k-D tree from the depth map. The k-D tree representing a hierarchical arrangement of regions of the depth map satisfying a requirement that a depth variation measure for undivided regions is below a threshold. A triangle mesh generator (107) positions an internal vertex within each region of the k-D tree. The triangle mesh is then generated by forming sides of triangles of the triangle mesh as lines between internal vertices of neighboring regions. The approach may generate an improved triangle mesh that is suitable for many 3D video processing algorithms.

    Abstract: An autostereoscopic display device has a particular design of display panel for use with a forming arrangement having non-slanted view forming elements (being for example a lenticular or parallax barrier array). The display panel sub-pixels incorporate a slant into their shape. The display panel is designed to enable low slant angles while still enabling efficient mapping of the 2D display panel pixels to the 3D pixels, allow for square 3D sub-pixels on rectangular grid which gives better distribution of color components with improved uniformity and improved rendering in 3D mode.

    Abstract: A multi-view display comprises a display panel comprising a regular array of pixels, each pixel comprising a rectangular array of sub-pixels of at least three colours, with a sub-pixel pitch in the row direction of r and a sub-pixel pitch in the column direction of c. A view forming arrangement is formed over the display panel and provides a view forming function in two directions. The view forming elements are arranged in grid of unit cells with a vector translation between adjacent unit cells which is designed such that the distribution of primary colours is equal for each view.

    Abstract: An image source (407) provides an image divided into segments of different sizes with only a subset of these comprising image data. A metadata generator (409) generates metadata structured in accordance with a tree data structure where each node is linked to a segment of the image. Each node is a branch node linking the parent node to child nodes linked to segments that are subdivisions of the parent node, or a leaf node which has no children. A leaf node is either an unused leaf node linked to a segment for which the first image comprises no image data or a used leaf node linked to a segment for which the first image comprises image data. The metadata indicates whether each node is a branch node, a used leaf node, or an unused leaf node. An image signal generator (405) generates an image signal comprising the image data of the first image and the metadata.

    Abstract: An apparatus comprises a receiver (401) receiving a first image and associated first depth data captured by a first depth-sensing camera. A detector (405) detects an image position property for a fiducial marker in the first image, the fiducial marker representing a placement of a second depth sensing image camera. A placement processor (407) determines a relative placement vector indicative of a placement of the second depth sensing image camera relative to the first depth-sensing camera in response to the image position property and depth data of the first depth data for an image position of the fiducial marker. A second receiver (403) receives a second image and second first depth data captured by the second depth sensing image camera. A generator (409) generates the representation of at least part the scene in response to a combination of at least the first image and the second image based on the relative placement vector.
