Title (EN) METHOD FOR GENERATING COMPUTER-GENERATED HOLOGRAM USING BLOCK MOTION COMPENSATION OF IMAGE AND LOOKUP TABLE
(FR) PROCÉDÉ POUR GÉNÉRER UN HOLOGRAMME GÉNÉRÉ PAR ORDINATEUR À L'AIDE D'UNE COMPENSATION DE MOUVEMENT DE BLOC D'UNE IMAGE ET D'UNE TABLE DE RECHERCHE
(KO) 룩업 테이블과 영상의 블록 움직임 보상을 이용한 컴퓨터 형성 홀로그램 산출 방법
Abstract: front page image
(EN)The present invention relates to a method for generating a computer-generated hologram using a block motion compensation of an image and a lookup table, the method quickly generating a video hologram having a quickly moving three-dimensional object, by using a block motion compensation of an image and a lookup table, and the more duplicate data is removed, the more hologram generation speed is improved. Furthermore, a block motion compensation technique is effective in compressing a video image having a quickly moving three-dimensional object. Additionally, motion vector information used in a conventional MPEG-based two-dimensional image compression technique is directly used to achieve a remarkable effect of using a conventional compressed MPEG video stream in the generation of a hologram without decoding.
(FR)La présente invention concerne un procédé pour générer un hologramme généré par ordinateur à l'aide d'une compensation de mouvement de bloc d'une image et d'une table de recherche, le procédé générant rapidement un hologramme vidéo ayant un objet tridimensionnel se déplaçant rapidement, par utilisation d'une compensation de mouvement de bloc d'une image et d'une table de recherche, et plus de données en double sont supprimées, plus la vitesse de génération d'hologramme est améliorée. En outre, une technique de compensation de mouvement de bloc est efficace lorsqu'il s'agit de compresser une image vidéo ayant un objet tridimensionnel se déplaçant rapidement. En outre, des informations de vecteur de mouvement utilisées dans une technique de compression d'image bidimensionnelle compatible MPEG classique sont directement utilisées pour obtenir un effet remarquable d'utilisation d'un flux vidéo MPEG compressé classique dans la génération d'un hologramme sans décodage.
(KO)본 발명은 룩업 테이블과 영상의 블록 움직임 보상을 이용한 컴퓨터 형성 홀로그램 산출 방법에 관한 것으로, 룩업 테이블과 영상의 블록 움직임 보상을 이용하여 빠른 움직임을 가지는 삼차원 물체를 가지는 비디오 홀로그램을 빠르게 생성하는 것이 특징인 것으로, 중복된 데이터가 많이 제거될수록 홀로그램의 생성 속도는 향상되며, 게다가 블록 움직임 보상 기법은 빠르게 움직이는 삼차원 물체를 가지는 비디오 영상을 압축하는데 효과적이며, 추가적으로 기존의 MPEG기반의 이차원 영상의 압축 기법에서 사용되는 모션벡터 정보를 바로 사용함으로 기존의 압축된 MPEG 비디오 스트림을 디코딩하지 않고 홀로그램 생성에 사용할 수 있는 현저한 효과가 있다.
