METHOD, APPARATUS, AND MEDIUM FOR VIDEO PROCESSING

WIPO Patent Application WO/2023/051654

A1

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.
