Abstract:
(EN) An image coding method, according to the present invention, comprises the steps of: generating a 360-degree projected image comprising a plurality of faces by means of the projective transformation of a three-dimensional 360-degree image on a two-dimensional plane; adding a padding region to a border on at least one side of the current face among the plurality of faces; and coding information associated with the padding of the current face, wherein the padding region is generated on the basis of a sample included in at least one portion of a face that is not neighboring the current face in the 360-degree projected image.
(FR) La présente invention concerne un procédé de codage d'image comprenant les étapes consistant à : générer une image projetée à 360° contenant une pluralité de visages au moyen de la transformation projective d'une image tridimensionnelle à 360° sur un plan bidimensionnel ; ajouter une région de remplissage à une bordure sur au moins un côté d’un visage actuel parmi la pluralité de visages ; et coder des informations associées au remplissage du visage actuel, la région de remplissage étant générée sur la base d'un échantillon inclus dans au moins une portion d’un visage qui n'est pas adjacente au visage actuel dans l'image projetée à 360°.
(KO) 본 발명에 따른 영상 부호화 방법은, 3차원의 360도 영상을 2차원 평면에 투영 변환함으로써 복수 의 페이스를 포함하는 360도 투사 영상을 생성하는 단계, 복수의 페이스 중 현재 페이스의 적어도 일측 경계에 패딩 영역을 추가하는 단계, 및 현재 페이스의 패딩 관련 정보를 부호화하는 단계를 포함하며, 패딩 영역은 360도 투사 영상에서 현재 페이스와 이웃하지 않는 페이스의 적어도 일부 에 포함된 샘플을 기초로 생성되는 것을 특징으로 한다.
