Title:
METHOD AND APPARATUS FOR ENCODING/DECODING IMAGE, FOR PERFORMING DEBLOCKING FILTERING BY DETERMINING BOUNDARY STRENGTH, AND METHOD FOR TRANSMITTING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2021/194155
Kind Code:
A1
Abstract:
A method and an apparatus for encoding/decoding an image are provided. The method for decoding an image, according to the present disclosure, comprises the steps of: obtaining a reconstructed picture; determining a target boundary of a deblocking filter in the reconstructed picture; determining a boundary strength for the target boundary; and applying the deblocking filter to the target boundary on the basis of the boundary strength, wherein when the target boundary is a transform block boundary and a color component of the reconstructed picture is a chroma component, the boundary strength is determined on the basis of whether joint CbCr residual encoding is performed on at least one of two blocks adjacent to the target boundary, and the joint CbCr residual encoding may correspond to encoding residual samples for a chroma Cb component and a chroma Cr component into a single transform block.
