Abstract:
Encoding and decoding methods and apparatuses, an encoder and a decoder, a code stream, and a storage medium. The decoding method comprises: decoding a point cloud code stream, and obtaining a first flag bit, the first flag bit being used for representing whether attribute coefficients of at least two first attribute components of a current point are both a first numerical value; and when the first flag bit represents that the attribute coefficients of the at least two first attribute components are both the first numerical value, determining that a first attribute coefficient of a second attribute component of the current point is equal to a second attribute coefficient of the second attribute component plus one, the second attribute coefficient of the second attribute component being obtained by parsing from the point cloud code stream, and the second attribute component being different from the at least two first attribute components.
