Title (EN) IMAGE ENCODING/DECODING METHOD
(FR) PROCÉDÉ DE CODAGE/DÉCODAGE D'IMAGES
(KO) 영상 부호화/복호화 방법
Abstract: front page image
(EN) The present invention relates to a method for carrying out motion compensation using motion vector prediction. An image decoding method therefor may comprise the steps of: acquiring a residual signal quantized for the current block; inverse-quantizing the quantized residual signal; and determining a transformation scheme for inverse-transforming the residual signal. The inverse transformation comprises a primary transformation and secondary transformation, and at least one from among a primary transformation scheme and secondary transformation scheme can be derived from a reconstructed block, around the current block, for which decoding is complete.
(FR) La présente invention concerne un procédé destiné à réaliser une compensation de mouvement en utilisant une prédiction de vecteurs de mouvement. Un procédé de décodage d'images associé peut comporter les étapes consistant à: acquérir un signal résiduel quantifié pour le bloc courant; appliquer une quantification inverse au signal résiduel quantifié; et déterminer un schéma de transformation servant à la transformation inverse du signal résiduel. La transformation inverse comporte une transformation primaire et une transformation secondaire, et au moins un schéma parmi un schéma de transformation primaire et un schéma de transformation secondaire peut être déduit d'un bloc reconstitué, autour du bloc courant, pour lequel le décodage est achevé.
(KO) 본 발명은 움직임 벡터 예측을 이용하여 움직임 보상을 수행하는 방법에 관한 것이다. 이를 위한 영상 복호화 방법은, 현재 블록에 대한 양자화된 잔차 신호를 획득하는 단계, 상기 양자화된 잔차 신호를 역양자화하는 단계, 및 상기 잔차 신호를 역변환하기 위한 변환 기법을 결정하는 단계를 포함할 수 있다. 이때, 상기 역변환은, 1차 변환 및 2차 변환을 포함하고, 1차 변환 기법 또는 2차 변환 기법 중 적어도 하나는, 상기 현재 블록 주변의 복호화가 완료된 복원 블록으로부터 유도될 수 있다.
