CODING SCHEME FOR VIDEO DATA USING DOWN-SAMPLING/UP-SAMPLING AND NON-LINEAR FILTER FOR DEPTH MAP

Methods of encoding and decoding video data are provided. In an encoding method, source video data comprising one or more source views is encoded into a video bitstream. Depth data of at least one of the source views is nonlinearly filtered and downsampled prior to encoding. After decoding, the decoded depth data is up-sampled and nonlinearly filtered.

20230011027 · 2023-01-12 ·

Disclosed herein is a method for encoding an immersive image. The method includes detecting a non-diffuse surface in a first texture image of a first view, generating an additional texture image from the first texture image based on the detected non-diffuse surface, performing pruning on the additional texture image based on a second texture image of a second view, generating a texture atlas based on the pruned additional texture image, and encoding the texture atlas.

Method for image processing of image data for image and visual effects on a two-dimensional display wall

A captured scene captured of a live action scene while a display wall is positioned to be part of the live action scene may be processed. To perform the processing, image data of the live action scene having a live actor and the display wall displaying a first rendering of a precursor image is received. Further, precursor metadata for the precursor image displayed on the display wall and display wall metadata for the display wall is determined. An image matte is accessed, where the image matte indicates a first portion associated with the live actor and a second portion associated with the precursor image on the display wall in the live action scene. Pixel display values to add or modify an image effect or a visual effect are determined, and the image data is adjusted using the pixel display values and the image matte.

An apparatus and method provide logic for processing information. In one implementation, an apparatus includes a display unit configured to display a first stereoscopic image. The first stereoscopic image includes a first and a second content, which may be disposed at corresponding display positions in a depth direction, and at least a portion of the first content appears to overlap at least a portion of the second content. A position-changing unit is configured to modify the display positions of the first and second content, in response to the apparent overlap. A control unit is configured to generate a signal to display, a second stereoscopic image that includes the first and second content disposed at the modified display positions. The display unit is further configured to display the second stereoscopic image such that the second stereoscopic image reduces the apparent overlap between the first and second content.

A METHOD AND APPARATUS FOR ENCODING AND DECODING VOLUMETRIC CONTENT IN AND FROM A DATA STREAM
20230239451 · 2023-07-27 ·

Methods and apparatus for encoding and decoding a volumetric scene are disclosed. A set of attribute and geometry patches is obtained by projecting samples of the volumetric scene onto the patches according to projection parameters. If the geometry patch is comparable to a planar layer located at a constant depth according to the projection parameters, only the attribute patch is packed in an attribute atlas image and the depth value is encoded in metadata. Otherwise, both attribute and geometry patches are packed in an atlas. At the decoding, if metadata for an attribute patch indicates that its geometry may be determined from the projection parameters and a constant depth, the attributes are inverse projected on a planar layer. Otherwise, attributes are inverse projected according to the associated geometry patch.

DIRECTED INTERPOLATION AND DATA POST-PROCESSING

An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.
