The present disclosure provides a loop filtering method which includes determining a clip index parameter of a loop filter, and encoding the clip index parameter by using a non-exponential Golomb encoding method.

Loop filtering method and device

A video encoding method includes encoding images of an image sequence to generate a bitstream of the image sequence. Different identifiers are used for two chrominance components of one image in a syntax element of an image level in the bitstream to indicate whether the corresponding chrominance components are filtered by adaptive loop filtering (ALF).

Method and device for video encoding and decoding and storage medium

An in-loop filtering method includes determining a target filter for a chrominance component of a current block of an image from a plurality of cross-component ALF filters, determining target filter coefficients for the chrominance component according to the chrominance component after ALF and a luminance component of the current block without ALF, filtering the chrominance component after ALF according to the target filter and the target filter coefficients, determining a filtered chrominance component of the current block according to the chrominance component after being filtered with the target filter coefficients and the chrominance component after the ALF, encoding according to the filtered chrominance component of the current block, and encoding a total number of the plurality of cross-component ALF filters as a syntax element. A stream of the image includes only one syntax element for indicating the total number of the plurality of cross-component ALF filters.

In-loop filtering method and device

A video encoding and decoding method includes determining an image block set based on one or more similar image blocks of an image block to be processed, generating an initial structure matrix of the image block set based on a pixel value of each image block in the image block set, and performing a filtering process on the initial structure matrix to obtain a reconstructed structure matrix. The reconstructed structure matrix corresponds to a reconstructed pixel value of the each image block. The filtering process includes one or more point-fixing processes. The method further includes reconstructing the each image block based on the reconstructed pixel value of the each image block.
