Title:
IMAGE ENCODING/DECODING METHOD AND APPARATUS, AND RECORDING MEDIUM IN WHICH BITSTREAM IS STORED
Document Type and Number:
WIPO Patent Application WO/2021/107532
Kind Code:
A1
Abstract:
An image encoding/decoding method and apparatus is provided. An image decoding method according to the present disclosure may comprise the steps of: acquiring a partitioning index of a current block from a bitstream; and performing a weighted summation of a prediction sample of a first subblock of the current block and a prediction sample of a second subblock of the current block, on the basis of the partitioning index, to generate a prediction sample of the current block, wherein the partitioning index indicates a partitioning distance and a partitioning direction included in a predefined table.
