(KO) 영상 부호화/복호화 방법 및 장치
Abstract: front page image
(EN)The present invention relates to an image encoding/decoding method and device. The image encoding method, according to the present invention, may comprise the steps of: generating a transform block by performing at least one of transformation and quantization; grouping at least one coefficient included in the transform block into at least one coefficient group (CG); scanning at least one coefficient included in the CG; and encoding the at least one coefficient.
(FR)La présente invention concerne un procédé et un dispositif de codage/de décodage d'une image. Selon l'invention, le procédé de codage d'image peut comprendre les étapes suivantes : génération d'un bloc de transformée en effectuant au moins une transformation et une quantification ; regroupement d'au moins un coefficient inclus dans le bloc de transformée en au moins un groupe de coefficients (CG) ; balayage d'au moins un coefficient inclus dans le CG ; et codage du ou des coefficients.
(KO)본 발명은 영상 부호화/복호화 방법 및 장치에 관한 것이다. 본 발명에 따른 영상 부호화 방법은, 변환 및 양자화 중 적어도 하나를 수행하여 변환 블록을 생성하는 단계, 상기 변환 블록에 포함된 적어도 하나의 계수를 적어도 하나의 계수 그룹(Coefficient Group, CG)으로 그룹핑하는 단계, 상기 계수 그룹에 포함된 적어도 하나의 계수를 스캐닝하는 단계, 및 상기 적어도 하나의 계수를 부호화하는 단계를 포함할 수 있다.
