Abstract: front page image
(EN)The present invention relates to a method and an apparatus for encoding/decoding images using adaptive motion vector resolution. The method for encoding the images of the present invention comprises the steps of: determining motion vector resolution in each region or each motion vector; and performing inter-prediction encoding by using the motion vector according to the motion vector resolution determined in each region or each motion vector. The present invention can efficiently encode the images by adaptively changing the motion vector resolution in predetermined region units of the images and performing the inter-prediction encoding for the images.
(FR)La présente invention a trait à un procédé et un appareil pour coder/décoder des images au moyen d'une résolution de vecteur de mouvement adaptative. Le procédé permettant de coder les images et faisant l'objet de la présente invention consiste : à définir une résolution de vecteur de mouvement pour chaque zone ou pour chaque vecteur de mouvement; et à effectuer un codage basé sur l'inter-prédiction grâce à l'utilisation du vecteur de mouvement en fonction de la résolution de vecteur de mouvement définie pour chaque zone ou pour chaque vecteur de mouvement. Cette invention permet de coder efficacement les images par la modification adaptative de la résolution d'un vecteur de mouvement dans des unités de zones prédéfinies des images, et par la réalisation d'un codage des images basé sur l'inter-prédiction.
(KO)본 발명은 적응적 움직임 벡터 해상도를 이용한 영상 부호화/복호화 방법 및 장치에 관한 것이다. 본 발명은 영상을 부호화하는 방법에 있어서, 영역 또는 움직임 벡터마다 움직임 벡터 해상도를 결정하는 단계; 및 영역 또는 움직임 벡터마다 결정된 움직임 벡터 해상도에 따른 움직임 벡터를 이용하여 인터 예측 부호화하는 단계를 포함하는 것을 특징으로 하는 영상 부호화 방법을 제공한다. 본 발명에 의하면, 영상을 소정의 영역 단위로 움직임 벡터 해상도를 적응적으로 변경하여 인터 예측 부호화함으로써, 영상을 효율적으로 부호화할 수 있다.
