Abstract
An encoding method, a decoding method, a decoder, and a storage medium are provided in embodiments of the disclosure. The decoding method includes the following. A bitstream is parsed to determine first information. A target value of a first scaling factor is determined from multiple candidate values of the first scaling factor according to the first information. A first residual picture is determined by performing loop filtering on a reconstructed picture according to a neural network. A loop-filtered reconstructed picture is determined by refining the first residual picture according to the target value of the first scaling factor.

A decoding method, applied to a decoder and comprising:
- parsing a bitstream to determine first information;
- determining a target value of a first scaling factor from a plurality of candidate values of the first scaling factor according to the first information;
- determining a first residual picture by performing loop filtering on a reconstructed picture according to a neural network;
- and
- determining a loop-filtered reconstructed picture by refining the first residual picture according to the target value of the first scaling factor.
An encoding method, applied to an encoder and comprising:
- determining a reconstructed picture of an original picture;
- determining a first residual picture by performing loop filtering on the reconstructed picture according to a neural network;
- determining a plurality of output pictures by refining the first residual picture according to a plurality of candidate values of a first scaling factor;
- and
- determining a target value of the first scaling factor from the plurality of candidate values according to the plurality of output pictures.
A decoder, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, causes the at least one processor to:
- parse a bitstream to determine first information;
- and
- determine a target value of a first scaling factor from a plurality of candidate values of the first scaling factor according to the first information;
- determine a first residual picture by performing loop filtering on a reconstructed picture according to a neural network;
- and determine a loop-filtered reconstructed picture by refining the first residual picture according to the target value of the first scaling factor.
