MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091673 A) filed by Guangdong Oppo Mobile Telecommunications Corp. on July 28, 2026, for Encoding Method, Decoding Method, Bit Stream, Encoder, Decoder And Storage Medium.
Inventor includes Song, Nan.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Disclosed in the embodiments of the present application are an encoding method, a decoding method, a bit stream, an encoder, a decoder and a storage medium. The decoding method comprises: at a decoding end, decoding a bit stream to determine first identification information; when, on the basis of the first identification information, it is determined to use a CCALF to perform filtering processing on a current color component of a current image, determining a scale factor and a filtering coefficient corresponding to the current color component; and on the basis of the scale factor and the filtering coefficient, determining a reconstructed block of a current block. The encoding method comprises: at an encoding end, determining a scale factor corresponding to a current color component of a current image; and on the basis of a rate distortion cost corresponding to the scale factor, determining first identification information, and writing the first identification information into a bit stream, wherein the first identification information is used for indicating whether to use a CCALF to perform filtering processing on the current color component of the current image.
