Main Inventor

Yin ZHAO

Brief explanation

This abstract describes a method for decoding video. It involves analyzing the video's data to determine how to transform different parts of the video. Each part, called a transform unit (TU), is assigned a serial number based on its position in the video. The method then calculates the transform coefficient for the luminance transform block of each TU. The type of transformation for each block is determined based on the split mode and the serial number of the TU. An inverse transformation is applied to the transform coefficient to obtain the reconstructed residual of the luminance transform block. Finally, a reconstructed block of the video is generated based on the reconstructed residuals.

Abstract

A video decoding method includes parsing a bitstream to obtain a split mode to transform units (TUs) in a current coding unit (CU). Each of the TUs includes a serial number in a one-to-one correspondence with positions of the TUs in the current CU. A transform coefficient of a luminance transform block of a current TU in the TUs is obtained. A transform type of the luminance transform block of the current TU is obtained based on the split mode and a serial number of the current TU. An inverse transform on the transform coefficient of the luminance transform block of the current TU is performed based on the transform type of the luminance transform block of the current TU to obtain a reconstructed residual of the luminance transform block of the current TU. A reconstructed block of the current CU is obtained based on the reconstructed residual.

METHOD FOR CHROMA SUBSAMPLED FORMATS HANDLING IN MACHINE-LEARNING-BASED PICTURE CODING (18320221)

Main Inventor

Han Gao

Brief explanation

The abstract describes a method for encoding and decoding pictures or videos. It explains that a picture is made up of a luma component (brightness) and a chroma component (color) with a lower resolution. To match the resolutions of both components, a selection is made between reducing the resolution of the luma component or increasing the resolution of the chroma component. The chosen processing is then applied to the picture, and a bitstream is generated based on the selected processing. This selection allows for adapting the picture for different applications, such as reducing complexity or bitrate, or aiming for higher quality.

Abstract

The present disclosure relates to picture or video encoding and decoding. A picture portion includes a luma component and a chroma component with a resolution lower than a resolution of the luma component. To obtain matching resolution of the luma component and the chroma component, a selection is performed between a down-sampling processing of the luma component and an up-sampling processing of the chroma component. Then, the selected processing is applied to a picture portion. The bitstream is then generated based on the selected processing, and includes encoding the processed picture portion. The selection between chroma up-sampling and luma down-sampling enables adaption of the input picture portion for the desired application. For example, some applications may aim at reducing complexity or bitrate in which case the luma down-sampling may be more favorable, whereas other application may aim at higher quality in which case chroma up-sampling may be more favorable.

Tile Group Signaling In Video Coding (18336804)

Main Inventor

FNU Hendry

Brief explanation

This abstract describes a method used in a video encoder to encode a video bitstream. The video bitstream contains coded data for multiple pictures, each of which consists of at least one slice. The method involves encoding a flag that indicates whether the tile information for a picture is present in a picture parameter set or in a slice header. The tile information specifies the location of a slice within the picture. 

If the flag indicates that the tile information for the picture is encoded in the picture parameter set, then the tile information is only encoded in the picture parameter set. On the other hand, if the flag indicates that the tile information for the picture is encoded in the slice header, then the tile information is only encoded in the slice header.

Finally, the method encodes the data of the picture in the video bitstream based on the tile information.

Abstract

A method implemented in an encoder for encoding a video bitstream that includes coded data for a plurality of pictures, each of the plurality of pictures comprises at least one slice. The method includes encoding a flag that indicates whether tile information for a picture is present in a picture parameter set or present in a slice header, where the tile information indicates a location of a slice within the picture; encoding the tile information in only the picture parameter set when the flag indicates that the tile information for the picture is encoded in the picture parameter set; encoding the tile information in only the slice header when the flag indicates that the tile information for the picture is encoded in the slice header; and encoding data of the picture in the video bitstream based on the tile information.

Main Inventor

Sergey Yurievich Ikonin

Brief explanation

This abstract describes a method and apparatus for encoding data, such as still or video processing, into a bitstream. The data is processed by a network with multiple layers, generating feature maps with different resolutions. A layer is selected from the cascaded layers, different from the layer with the lowest resolution, and information related to this selected layer is included in the bitstream. This allows for efficient coding of data with varying resolutions, depending on the content of the picture data being coded.

Abstract

The present disclosure relates to methods and apparatuses for encoding data for (still or video processing into a bitstream). In particular, the data are processed by a network which includes a plurality of cascaded layers. In the processing, feature maps are generated by the layers. The feature maps processed (output) by at least two different layers have different resolutions. In the processing, a layer is selected, out of the cascaded layers, which is different from the layer generating the feature map of the lowest resolution (e.g. latent space). The bitstream includes information related to the selected layer. With this approach, scalable processing which may operate on different resolutions is provided so that the bitstream may convey information relating to such different resolutions. Accordingly, the data may be efficiently coded within the bitstream, depending on the resolution which may vary depending on the content of the picture data coded.

Main Inventor

Sergey Yurievich Ikonin

Brief explanation

This disclosure describes methods and devices for decoding data, such as still images or videos, into a bitstream. The process involves obtaining multiple sets of segmentation information elements from the bitstream. Each set of segmentation information elements is then inputted into a respective segmentation information processing layer out of several cascaded layers. In each layer, the segmentation information is processed. Finally, the decoded data for picture or video processing is obtained based on the processed segmentation information from the cascaded layers. This approach allows for efficient decoding of data from the bitstream using a layered structure.

Abstract

The present disclosure relates to methods and apparatuses for decoding data for (still or video processing into a bitstream). Two or more sets of segmentation information elements are obtained from the bitstream. Then, each of the two or more sets of segmentation information elements are inputted respectively into two or more segmentation information processing layers out of a plurality of cascaded layers. In each of the two or more segmentation information processing layers, the respective sets of segmentation information are processed. The decoded data for picture or video processing are obtained based on the segmentation information processed by the plurality of cascaded layers. Accordingly, the data may be decoded from the bitstream in an efficient manner in the layered structure.

METHOD FOR CHROMA SUBSAMPLED FORMATS HANDLING IN MACHINE-LEARNING-BASED PICTURE CODING (18320222)

Main Inventor

Han Gao

Brief explanation

The abstract describes a method for encoding and decoding video using machine learning. It specifically focuses on handling chroma subsampled formats, where the chroma component has a lower resolution than the luma component. To address this, the chroma component is up-sampled to match the resolution of the luma component before encoding. During decoding, the luma component and an intermediate chroma component are decoded from the bitstream, and the intermediate chroma component is then down-sampled to match the resolution of the luma component. This allows for the handling of sub-sampled chroma formats while preserving the luma channel.

Abstract

The present disclosure relates to video encoding and decoding, and in particular to handling of chroma subsampled formats in machine-learning-based video coding. Corresponding apparatuses and methods enable the processing for encoding and decoding of a respective picture portion that includes a luma component and a chroma component with a resolution lower than the luma component. In order to handle such different sized luma-chroma channels, the chroma component is up-sampled such that the obtained up-sampled chroma component has a resolution matching the one of the luma component. The luma and the up-sampled chroma component are then encoded into a bitstream. To reconstruct the picture portion, the luma component and an intermediate chroma component matching the resolution of the luma component are decoded from the bitstream, followed by down-sampling the intermediate chroma component. Thus, sub-sampled chroma formats may be handled by an autoencoder/autodecoder framework, while preserving the luma channel.

DECODING AND ENCODING OF NEURAL-NETWORK-BASED BITSTREAMS (18336735)

Main Inventor

Semih Esenlik

Brief explanation

The abstract describes a method for decoding and encoding pictures using neural networks. The picture is represented by a set of samples obtained from a bitstream. The picture is reconstructed by processing the input set and generating output subsets. The input set is divided into smaller subsets and each subset is processed by a neural network. The neural network takes multiple samples from an input subset and generates one sample for an output subset. The reconstructed picture is obtained by combining the output subsets. The method involves using smaller input subsets than the required size for the corresponding output subsets after processing by the neural network layers.

Abstract

For picture decoding and encoding of neural-network-based bitstreams, a picture is represented by an input set of samples which is obtained from the bitstream. The picture is reconstructed from output subsets, which are generated as a result of processing the input set L. The input set is divided into multiple input subsets Li. The input subsets are each subject to processing with a neural network having one or more layers. The neural network uses as input multiple samples of an input subset and generates one sample of an output subset. By combining the output subsets, the picture is reconstructed. In particular, the size of at least one input subset is smaller than a size that is required to obtain the size of the respective output subset, after processing by the one or more layers of the neural network.
