Abstract:
(EN) Provided are a method and a device for generating a prediction block of a chroma component from a restored luma component by modeling a correlation between the luma component and the chroma component during video encoding and decoding processes. A video decoding method for resolving a technical problem, presented in the present disclosure, can comprise the steps of: deriving weighted value information and deviation information on a chroma sample of a restored adjacent chroma block neighboring a current chroma block and a restored luma sample of an adjacent luma block corresponding to the adjacent chroma block in order to restore chroma samples of the current chroma block; restoring luma samples of the current luma block according to a prediction mode of the current luma block corresponding to the current chroma block; and restoring the chroma sample of the current chroma block by using the restored luma samples of the current luma block, the weighted value information and the deviation information.
(FR) L'invention concerne un procédé et un dispositif de génération d’un bloc de prédiction d'une composante de chrominance à partir d'une composante de luminance restaurée par modélisation d'une corrélation entre la composante de luminance et la composante de chrominance pendant des processus de codage et de décodage vidéo. Un procédé de décodage vidéo apte à résoudre un problème technique, selon la présente invention, peut comprendre les étapes consistant à : dériver des informations de valeur pondérée et des informations de déviation sur un échantillon de chrominance d'un bloc de chrominance adjacent restauré voisin d'un bloc de chrominance actuel et un échantillon de luminance restauré d'un bloc de luminance adjacent correspondant au bloc de chrominance adjacent afin de restaurer des échantillons de chrominance du bloc de chrominance actuel ; restaurer des échantillons de luminance du bloc de luminance actuel selon un mode de prédiction du bloc de luminance actuel correspondant au bloc de chrominance actuel ; et restaurer l'échantillon de chrominance du bloc de chrominance actuel à l'aide des échantillons de luminance restaurés du bloc de luminance actuel, des informations de valeur pondérée et des informations de déviation.
(KO) 비디오 부호화 및 복호화 과정 중에서, 루마 성분 및 크로마 성분의 상관관계를 이용하여 모델링함으로써 복원된 루마 성분으로부터 크로마 성분의 예측 블록을 생성하는 방법 및 장치를 제안한다. 상기 기술적 과제를 해결하기 위해 본 개시에서 제안하는 비디오 복호화 방법은, 현재 크로마 블록의 크로마 샘플들을 복원하기 위해 상기 현재 크로마 블록에 이웃하는 복원된 주변 크로마 블록의 크로마 샘플 및 상기 주변 크로마 블록에 대응하는 주변 루마 블록의 복원된 루마 샘플에 대한 가중치 정보 및 편차 정보를 도출하는 단계; 상기 현재 크로마 블록에 대응하는 현재 루마 블록의 예측 모드에 따라 상기 현재 루마 블록의 루마 샘플들을 복원하는 단계; 상기 현재 루마 블록의 복원된 루마 샘플들, 상기 가중치 정보, 및 상기 편차 정보를 이용하여 상기 현재 크로마 블록의 상기 크로마 샘플을 복원하는 단계를 포함할 수 있다.
