Title (EN) IMAGE DECODING METHOD AND DEVICE IN ACCORDANCE WITH BLOCK SPLIT STRUCTURE IN IMAGE CODING SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF DE DÉCODAGE D'IMAGE CONFORMES À UNE STRUCTURE DIVISÉE DE BLOCS DANS UN SYSTÈME DE CODAGE D'IMAGE
(KO) 영상 코딩 시스템에서 블록 분할 구조에 따른 영상 디코딩 방법 및 장치
Abstract:
(EN) An image decoding method performed by means of a decoding device according to the present invention comprises the steps of: obtaining first split information relating to a first target block; if the first split information indicates that the first target block is to be split, splitting the first target block into first sub-blocks; obtaining MPT split information relating to a second target block which is one of the first sub-blocks of the first target block; splitting the second target block into second sub-blocks on the basis of the MPT split information; and decoding the second sub-blocks, wherein the second sub-blocks are non-square blocks.
(FR) La présente invention concerne un procédé de décodage d'image mis en œuvre au moyen d'un dispositif de décodage comprend les étapes consistant à : obtenir des premières informations de division relatives à un premier bloc cible ; si les premières informations de division indiquent que le premier bloc cible doit être divisé, diviser le premier bloc cible en premiers sous-blocs ; obtenir des informations de division de MPT relatives à un second bloc cible, qui est l'un des premiers sous-blocs du premier bloc cible ; diviser le second bloc cible en seconds sous-blocs, en fonction des informations de division de MPT ; et décoder les seconds sous-blocs, les seconds sous-blocs étant des blocs non carrés.
(KO) 본 발명에 따른 디코딩 장치에 의하여 수행되는 영상 디코딩 방법은 제1 대상 블록에 대한 제1 분할(split) 정보를 획득하는 단계, 상기 제1 분할 정보가 상기 제1 대상 블록이 분할됨을 나타내는 경우, 상기 제1 대상 블록을 상기 제1 서브 블록들로 분할하는 단계, 상기 제1 대상 블록의 상기 제1 서브 블록들 중 하나인 제2 대상 블록에 대한 MPT 분할 정보를 획득하는 단계, 상기 MPT 분할 정보를 기반으로 상기 제2 대상 블록을 제2 서브 블록들로 분할하는 단계, 및 상기 제2 서브 블록들을 디코딩하는 단계를 포함함을 특징으로 하되, 상기 제2 서브 블록들은 비정방형 블록들인 것을 특징으로 한다.
