Title:
IMAGE DECODING METHOD AND DEVICE ACCORDING TO INTRA PREDICTION IN IMAGE CODING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/174358
Kind Code:
A1
Abstract:
An intra prediction method performed by a decoding device, according to the present invention, comprises the steps of: deriving an intra prediction mode for a current block; deriving neighboring samples of the current block; deriving reference samples for a target sample of the current block among the neighboring samples on the basis of the intra prediction mode; deriving weighted values of the reference samples for the target sample; and deriving a prediction sample of the target sample on the basis of the reference samples and the weighted values.
