Zusammenfassung:
(EN) The present invention is for the efficient encoding of a 360-degree image and the reduction of image quality degradation due to a discontinuity artifact, and includes a method for encoding a 360 image, the method comprising the steps of: generating a 2D image by projecting a 360 image on the basis of any one projection format among at least one projection format; encoding the 2D image which has been padded or not according to the padding or not of the 2D image according to the any one projection format that has become the basis; and encoding a syntax element for padding information of the 2D image.
(FR) La présente invention est destinée au codage efficace d'une image de 360 degrés et à la réduction de la dégradation de la qualité d'image due à un artefact de discontinuité, et comprend un procédé de codage d'une image à 360 degrés, le procédé comprenant les étapes consistant : à générer une image 2D par projection d'une image à 360 degrés sur la base d'un format de projection quelconque parmi au moins un format de projection; à coder l'image 2D qui a été remplie ou non selon le remplissage ou non de l'image 2D selon l'un quelconque des formats de projection qui ont pris la base; et coder un élément de syntaxe pour des informations de remplissage de l'image 2D.
(KO) 본 발명은 360도 영상을 효율적으로 부호화하고 불연속 현상(discontinuity artifact)에 의한 화 질 열화를 완화하기 위한 것으로, 하나 이상의 투영포맷 중 어느 하나의 투영포맷을 기초로 360 영상을 투영하여 2D 이미지를 생성하는 단계; 기초가 된 어느 하나의 투영포맷에 따른 2D 이미지의 패딩 여부에 따라 패딩되거나 패딩되지 않은 2D 이미지를 부호화하는 단계; 및 2D 이미지의 패딩정보에 대한 신택스 요소를 부호화하는 단계를 포함하는 360 영상의 부호화 방법을 포함한다.
