Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE USING PREDICTION COMBINING-BASED INTRA-SCREEN PREDICTION, AND METHOD FOR TRANSMITTING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2024/080831
Kind Code:
A1
Abstract:
An image encoding/decoding method and device are provided. An image decoding method by which an image decoding device performs, according to one embodiment of the present disclosure, may comprise the steps of: obtaining template-based intra prediction information of a current block; generating two or more prediction blocks for the current block on the basis of the template-based intra prediction information; and restoring the current block on the basis of a weighted sum of the two or more prediction blocks, and a weight for each prediction block used in the weighted sum may be determined on the basis of a template matching-based cost.
