Title:
ENCODING METHOD, DECODING METHOD, CODE STREAM, ENCODER, DECODER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/201450
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are an encoding method, a decoding method, a code stream, an encoder, a decoder, and a storage medium. The method comprises: determining a reconstructed slice of a reconstructed point cloud; when the reconstructed point cloud meets a preset condition, determining a first filter coefficient according to the reconstructed slice and an initial slice corresponding to the reconstructed slice; performing filter processing on the reconstructed slice according to the first filter coefficient, and determining a filtered slice corresponding to the reconstructed slice; determining first filter identification information according to the filtered slice, wherein the first filter identification information indicates whether to perform filter processing on the reconstructed slice; encoding the first filter identification information; if the first filter identification information indicates that filter processing is to be performed on the reconstructed slice, encoding the first filter coefficient; and writing an obtained encoded bit into a code stream. In this way, the quality of a point cloud can be improved; the present application has universality; and the code rate can also be reduced, thereby improving the encoding and decoding performance.
