Abstract: An example apparatus for displaying stereo elemental images includes two coupled eyepieces. Each of the two eyepieces also includes a curved screen to display a number of elemental images. Each of the two eyepieces also includes a curved lens array concentrically displaced in front of the curved screen to magnify the elemental images. Each of the number of elemental images is magnified by a different lens in the curved lens array.

Abstract: Systems, devices, and techniques related to thin form factor head mounted displays and near light field displays are discussed. Such devices may include a display to present elemental images, a primary lens array in an optical path between the display and a viewing zone of a user, the primary lens array to magnify elemental images to a viewing zone, and a secondary array of optical elements between the display and the primary lens array to concentrate elemental images from the display to the primary lens array.

Abstract: An example apparatus for encoding immersive video includes a view optimizer to receive a plurality of input views from a source camera and select basic views and additional views from the plurality of input views. The apparatus also includes a view pruner to prune the additional views based on a comparison with the basic views. The apparatus further includes a patch packer to generate atlases based on the pruned additional views and the basic views. The apparatus includes a metadata composer to generate metadata including additional metadata. The apparatus also further includes a bitstream generator to generate a bitstream including the encoded video and the metadata.

Abstract: Methods, apparatus, systems and articles of manufacture to generate packed video frames are disclosed. A video encoding system disclosed herein includes a configuration determiner to create a packed video frame layout that includes regions into which video components are to be placed. The system also includes a frame generator to form packed video frames that include the video components placed into different regions. The encoding system further includes a frame information generator that generates packed video frame information that identifies characteristics of the packed video frame including (i) the identities of regions included in the packed video frame layout, (ii) types of video components included in the regions, or iii) information identifying the locations and dimensions of the regions. A video encoder of the encoding system encodes the frames and includes the packed video frame information to signal the inclusion of the packed video frames in the encoded bitstream.

Abstract: Methods, apparatus, systems and articles of manufacture to sample enabled views per atlas in immersive video are disclosed. An example apparatus includes an interface to obtain a bitstream corresponding to an immersive video; a bitstream analyzer to determine that metadata corresponding to an atlas of the bitstream identifies that at least part of a view of interest corresponds to the atlas, the metadata included in the bitstream; and a filter to generate a filtered bitstream by removing atlases that do not identify at least part of a view of interest from the bitstream, the interface to provide the filtered bitstream to a decoder.

Abstract: An embodiment of an image processor for immersive video includes technology to re-order patches from a plurality of views based on one or more of relative position and orientation related information for a desired synthesized view, select a set of views to be used in each view synthesis pass, perform two or more view synthesis passes for the synthesized view to provide two or more intermediate view synthesis results, and mask and merge the two or more intermediate view synthesis results to provide a final view synthesis result. Other embodiments are disclosed and claimed.

Abstract: Techniques are provided for perception enhancement of light fields (LFs) for use in integral display applications. A methodology implementing the techniques according to an embodiment includes receiving one or more LF views and a disparity map associated with each LF view. The method also includes quantizing the disparity map into planes, where each plane is associated with a selected range of depth values. The method further includes slicing the LF view into layers, where each layer comprises pixels of the LF view associated with one of the planes. The method further includes shifting each of the layers in a lateral direction by an offset distance. The offset distance is based on a viewing angle associated with the LF view and further based on the depth values of the associated plane. The method also includes merging the shifted layers to generate a synthesized LF view with increased parallax.
