摘要:
Disclosed herein is a method for volumizing and encoding a plurality of two-dimensional images of a subject. The method may comprise obtaining a plurality of two-dimensional (2D) images of the subject, wherein each 2D image of the plurality of 2D images is captured at a different angle from the subject. The method may further comprise generating at least one volumizing hierarchical grid corresponding to the plurality of 2D images. The method may further comprise generating a 3D representation from the at least one volumizing hierarchical grid. The method may further comprise generating an encoding hierarchical grid corresponding to the 3D representation to form a plurality of image blocks. The method may further comprise individually processing the plurality of image blocks to form a plurality of processed image blocks.

Examples of video encoding methods and apparatus and video decoding methods and apparatus are descrined. An example method of video processing includes performing a conversion between a video comprising a video picture comprising a slice and a bitstream of the video according to a rule. The rule specifies that a default value of a syntax element specifying a number of entries in a reference picture list syntax structure associated with a reference picture list (RPL) index is equal to 0 due to a condition being satisfied. The condition is satisfied in case (1) the video picture is an instantaneous decoding refresh picture, (2) a first syntax flag specifies that RPL syntax elements are not present in a slice header of the slice, and (3) a second syntax flag specifies that RPL information is not present in a picture header of the video picture.
摘要:
An encoding apparatus employing both a CPU and a chip or circuit dedicated to the encoding is disclosed. The encoding apparatus includes a hardware encoder 151 and a software encoder 152. The hardware encoder 151 is configured by hardware dedicated to the encoding and encodes a portion of AV data. The software encoder 152 encodes another portion of the AV data in parallel to the encoding process of the hardware encoder 151 by the use of a CPU 10. A position detector 18 detects a switching position of an allocation destination in the AV data. A data allocator 14 allocates sections of the AV data divided by the switching position to both encoders 151 and 152. A synthesizer 16 arranges the encoded AV data in a predetermined sequence to synthesize a series of encoded AV data. An output unit 17 outputs the series of encoded AV data.

摘要:
A computer-implemented method for selecting efficient encoders for streaming media may include (i) predicting that an expected download demand for a higher-demand segment of a media file is higher than an expected download demand for a lower-demand segment, (ii) encoding each segment of the media file with an encoder that correlates to the expected download demand of the segment by (a) encoding the higher-demand segment with a more computationally intensive encoder that produces a more efficiently compressed segment compared to a less computationally intensive encoder that produces a less efficiently compressed segment and (b) encoding the lower-demand segment with the less computationally intensive encoder, and (iii) enabling streaming of the media file by providing the more efficiently compressed encoding of the higher-demand segment and the less efficiently compressed encoding of the lower-demand segment. Various other methods, systems, and computer-readable media are also disclosed.
摘要:
In a cloud-based system for encoding high dynamic range (HDR) video, each node receives a video segment and bumper frames. Each segment is subdivided into primary scenes and secondary scenes to derive scene-based forward reshaping functions that minimize the amount of reshaping-related metadata when coding the video segment, while maintaining temporal continuity among scenes processed by multiple nodes. Methods to generate scene-based forward and backward reshaping functions to optimize video coding and improve the coding efficiency of reshaping-related metadata are also examined.
