Aspects of the disclosure provide methods, apparatuses, and a non-transitory computer-readable storage medium for video encoding and video decoding. An apparatus for video decoding can include processing circuitry. The processing circuitry is configured to decode neural network update information in a coded bitstream for at least one neural network in the video decoder. The at least one neural network is configured with a set of pretrained parameters, and the neural network update information indicates a first modification parameter. The processing circuitry is configured to update the set of pretrained parameters in the at least one neural network in the video decoder based on the first modification parameter. The processing circuitry is configured to decode an encoded image based on the updated at least one neural network.

Aspects of the disclosure provide methods and apparatuses for video data processing. In some examples, an apparatus for video data processing includes processing circuitry. For example, the processing circuitry determines a first syntax element for coding control in a first scope of coded video data in a bitstream. The first syntax element is associated with a coding tool of persistent Rice adaptation defined in a range extension of a video standard for a statistics based Rice parameter derivation in a residual coding. In response to the first syntax element being a first value indicative of disabling of the coding tool in the first scope, the processing circuitry decodes the first scope of coded video data that includes one or more second scopes of coded video data without invoking the coding tool.

This disclosure describes systems, methods, and devices related to responder-to-responder Wi-Fi sensing between station devices. A device may cause to send, during a trigger frame sounding phase of a responder-to-responder Wi-Fi sensing, a sensing responder-to-responder sounding trigger frame to the first station device and the second station device, the sensing responder-to-responder sounding trigger frame associated with causing the first station device to send a responder-to-responder null data packet (NDP) to the second station device; cause to send, during a reporting phase of the responder-to-responder Wi-Fi sensing, a sensing report trigger frame to the second station device; and identify, during the reporting phase, a sensing measurement report from the second station device based on the sensing report trigger frame, wherein the sensing measurement report is indicative of measurements of the responder-to-responder NDP.

A method and apparatus for video coding. In some examples, an apparatus includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information of a block in a current picture from a coded video bitstream. The prediction information includes an index for prediction offset associated with an affine model in an inter prediction mode. The affine model is used to transform between the block and a reference block in a reference picture that has been reconstructed. Further, the processing circuitry determines parameters of the affine model based on the index and a pre-defined mapping of indexes and offset values, and reconstructs at least a sample of the block according to the affine model.

This disclosure is directed to systems and methods of rate control in multiple pass video encoding. The video encoder may complete multiple encoding passes for slices of an image. Rate control algorithms may be implemented that scale the quantization step size and quantization matrix values depending on the determined size of the image slices. This may enable the size of slices to be adjusted based on size parameters for the image data.

A coding apparatus is a coding apparatus for coding an original image and includes: a division section that divides the original image into blocks that are a plurality of areas to acquire the plurality of blocks; a determination section that, for each of the blocks, determines whether or not to determine the block as an interpolation target; and a substitution section that substitutes a value of a pixel included in the block determined as the interpolation target, with a value that decreases a code amount of the block determined as the interpolation target. The determination section determines whether or not to determine the area that is a target of the determination as an area that is the interpolation target, using an evaluation based on an accuracy of prediction of an image of the block by intra prediction or inter prediction and a degree of the area that is the interpolation target being a generated one.
