Title (EN) METHOD AND APPARATUS FOR PROCESSING VIDEO SIGNAL THROUGH TARGET AREA MODIFICATION
(FR) PROCÉDÉ ET APPAREIL DE TRAITEMENT DE SIGNAL VIDÉO PAR MODIFICATION DE ZONE CIBLE
(KO) 타겟 영역 수정을 통해 비디오 신호를 처리하는 방법 및 장치
Abstract:
(EN) The present invention provides a method for processing a video signal through target modification, the method comprising the steps of: obtaining a target modification flag from a sequence parameter set of the video signal, wherein the target modification flag indicates whether to perform a modification to the target area; obtaining a target modification index when performing a modification to the target area according to the target modification flag, wherein the target modification index indicates a target modification method and corresponds to at least one from among no modification, left/right symmetry conversion, up/down symmetry conversion, rotation conversion, and a combination thereof; identifying the target modification method corresponding to the target modification index; and performing inverse modification to the restored target area, according to the target correction method.
(FR) La présente invention concerne un procédé permettant de traiter un signal vidéo par modification de cible, le procédé comprenant les étapes consistant : à obtenir un drapeau de modification de cible à partir d'un ensemble de paramètres de séquence du signal vidéo, le drapeau de modification de cible indiquant s'il faut réaliser une modification de la zone cible; à obtenir un indice de modification de cible lors de la réalisation d'une modification de la zone cible selon le drapeau de modification de cible, l'indice de modification de cible indiquant un procédé de modification de cible et correspondant à aucune modification et/ou une conversion de symétrie gauche/droite et/ou une conversion de symétrie haut/ bas et/ou une conversion de rotation et/ou une combinaison de celles-ci; à identifier le procédé de modification de cible correspondant à l'indice de modification de cible; et à réaliser une modification inverse de la zone cible restaurée, selon le procédé de correction de cible.
(KO) 본 발명은, 타겟 수정을 통해 비디오 신호를 처리하는 방법에 있어서, 상기 비디오 신호의 시퀀스 파라미터 셋으로부터 타겟 수정 플래그를 획득하는 단계, 여기서 상기 타겟 수정 플래그는 타겟 영역에 대해 수정을 수행하는지 여부를 나타냄; 상기 타겟 수정 플래그에 따라 타겟 영역에 대해 수정을 수행하는 경우, 타겟 수정 인덱스를 획득하는 단계, 여기서 상기 타겟 수정 인덱스는 타겟 수정 방법을 나타내며, 수정 없음, 좌우 대칭 변환, 상하 대칭 변환, 회전 변환 또는 이들의 조합 중 적어도 하나에 대응됨; 상기 타겟 수정 인덱스에 대응되는 타겟 수정 방법을 확인하는 단계; 및 상기 타겟 수정 방법에 따라, 복원된 타겟 영역에 대해 역수정을 수행하는 단계를 포함하는 것을 특징으로 하는 방법을 제공한다.
