Title:
IMAGE ENCODING/DECODING METHOD AND RECORDING MEDIUM STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2024/010362
Kind Code:
A1
Abstract:
An image decoding method, according to the present disclosure, comprises the steps of: deriving a first prediction block for a current block; deriving a reference block for the current block; and updating the first prediction block on the basis of a second prediction block derived from the reference block. In the current block, a third prediction sample at a current prediction location is derived on the basis of a weighted sum calculation based on a first prediction sample in the first prediction block and a second prediction sample in the second prediction block, and a weight for the weighted sum calculation may be determined on the basis of a classification result at the current prediction location.
