Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM HAVING BITSTREAM STORED THEREIN
Document Type and Number:
WIPO Patent Application WO/2023/195708
Kind Code:
A1
Abstract:
An image encoding/decoding method and device according to the present disclosure may: construct a reference sample for linear model intra prediction on the basis of reconstructed neighboring samples of a current block; derive linear model parameters on the basis of the reference sample; generate a prediction sample of the current block on the basis of the linear model parameters; and encode/decode the current block on the basis of the prediction sample of the current block.
