Title:
IMAGE ENCODING/DECODING METHOD, METHOD FOR TRANSMITTING BITSTREAM, AND RECORDING MEDIUM STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2023/014076
Kind Code:
A1
Abstract:
Provided are an image encoding/decoding method, a bitstream transmission method, and a computer-readable recording medium that stores a bitstream. The image decoding method according to the present disclosure is performed by an image decoding apparatus, and comprises the steps of: applying deblocking filtering to reconstructed samples; and deriving a modified luma sample and modified chroma samples by applying one or more of sample adaptive offset (SAO) filtering and cross component sample adaptive offset (CC-SAO) filtering to the reconstructed samples to which the deblocking filtering has been applied, wherein the modified luma sample is derived by applying the SAO filtering to a luma sample to which the deblocking filtering has been applied, and the modified chroma samples are derived by applying the SAO filtering to chroma samples to which the deblocking filtering has been applied, and applying the CC-SAO filtering to chroma samples to which the deblocking filtering has been applied and a luma sample to which first in-loop filtering has been applied.
