Abstract: Embodiments of the present disclosure provide a solution for visual data processing. A method for visual data processing is proposed. The method comprises: performing, for a conversion between visual data and a bitstream of the visual data, a quantization process on a dataset comprising at least one of: input visual data of a neural network model used for the conversion, or a parameter of the neural network model; and performing the conversion based on the quantization process.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a target video block of a video and a bitstream of the video, a distortion metric for the target video block based at least in part on at least one distortion of: a set of filtered distortions of the target video block according to a set of machine learning models, or a second distortion of the target video block determined without using the set of machine learning models; determining, based on the distortion metric, information regarding using the set of machine learning models in a rate-distortion optimization (RDO) process on the target video block; and performing the conversion based on the information. In this way, the RDO process can be improved, and thus the coding performance can be enhanced.

Abstract: A method of processing video data. The method includes applying a super resolution (SR) process to a video unit at a level of an SR unit, where the SR unit includes more than one pixel of the video unit, and performing a conversion between a video comprising the video unit and a bitstream of the video based on the SR process as applied. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.

Abstract: A method implemented by a video coding apparatus. The method includes applying a first filter to an unfiltered sample of a video unit to generate a filtered sample. The first filter is a neural network (NN) filter based on a non-deep learning-based filter (NDLF) being disabled, and the first filter is the NDLF based on the NN filter being disabled. The method also includes performing a conversion between a video media file and a bitstream based on the filtered sample that was generated.
