Abstract
(EN)
A method for generating GT information of a moving object, according to the present invention, comprises the steps of: specifying a region in which a moving object, from which GT information is to be generated, exists in each of a start frame and a last frame of a scene in which the moving object exists; estimating the existence region of the moving object in each of one or more intermediate frames existing between the start frame and the last frame on the basis of the region in which the moving object exists in each of the start frame and the last frame; and determining the estimated existence region to be the position of the moving object in each of the one or more intermediate frames and can easily and accurately generate GT information of a moving object in a video.

La présente invention concerne un procédé de génération d'informations de réalité de terrain d'un objet en mouvement, comprenant les suivantes : spécification d'une région dans laquelle un objet en mouvement, à partir duquel doivent être générées des informations de réalité de terrain, existe dans chacune d'une trame de départ et d'une dernière trame d'une scène dans laquelle se trouve l'objet en mouvement ; estimation de la région d'existence de l'objet en mouvement dans chacune d'une ou de plusieurs trames intermédiaires existant entre la trame de départ et la dernière trame sur la base de la région dans laquelle l'objet en mouvement existe dans chacune de la trame de départ et de la dernière trame ; et détermination de la région d'existence estimée comme étant la position de l'objet en mouvement dans chacune desdites trames intermédiaires. Le procédé selon l'invention permet d générer facilement et avec précision des informations de réalité de terrain d'un objet mobile dans une vidéo.

본 발명에 따른 움직임 객체의 GT 정보 생성 방법은 GT 정보를 생성할 움직임 객체가 존재하는 장면의 시작 프레임과 마지막 프레임에서 각각 상기 움직임 객체가 존재하는 영역을 특정하는 단계와, 상기 시작 프레임과 마지막 프레임에서 각각 상기 움직임 객체가 존재하는 영역을 기초로, 상기 시작 프레임과 마지막 프레임에 존재하는 하나 이상의 중간 프레임 각각에서 움직임 객체의 존재 영역을 추정하는 단계와, 추정된 상기 존재 영역을 상기 하나 이상의 중간 프레임 각각에서 상기 움직임 객체의 위치로 결정하는 단계를 포함하며, 동영상의 움직임 객체의 GT 정보 생성를 용이하고 정확하게 생성할 수 있다.
