Title
(EN) METHOD AND DEVICE FOR IMPROVING VIDEO QUALITY
(FR) PROCÉDÉ ET DISPOSITIF D'AMÉLIORATION DE LA QUALITÉ VIDÉO
(KO) 비디오 품질 향상 방법 및 장치
Abstract
(EN) A method for improving video quality is disclosed. A method for improving video quality comprises the steps of: acquiring first motion information about a user control object from a frame included in a video; using a first neural network to acquire second motion information about the remaining pixels that excludes pixels included in the user control object from among pixels included in the frame; and using a second neural network to generate an interpolation frame between at least two frames from at least two frames, the first motion information and the second motion information.
(FR) L'invention divulgue un procédé d'amélioration de la qualité vidéo. Un procédé d'amélioration de la qualité vidéo comprend les étapes consistant à : acquérir des premières informations de mouvement concernant un objet de commande d'utilisateur à partir d'une image incluse dans une vidéo ; à l'aide d'un premier réseau de neurones pour acquérir des secondes informations de mouvement concernant les pixels restants qui excluent des pixels inclus dans l'objet de commande d'utilisateur parmi des pixels inclus dans l'image ; et utiliser un second réseau de neurones pour générer une image d'interpolation entre au moins deux images à partir d'au moins deux images, des premières informations de mouvement et des secondes informations de mouvement.
(KO) 비디오 품질 향상 방법이 개시된다. 비디오 품질 향상 방법은 비디오에 포함된 프레임에서 사용자 제어 오브젝트에 대한 제1 모션 정보를 획득하는 단계, 제1 뉴럴 네트워크를 이용하여, 프레임에 포함된 픽셀들 중 사용자 제어 오브젝트에 포함된 픽셀들을 제외한 나머지 픽셀들에 대한 제2 모션 정보를 획득하는 단계 및 제2 뉴럴 네트워크를 이용하여, 적어도 두 개의 프레임, 제1 모션 정보, 및 제2 모션 정보로부터 적어도 두 개의 프레임 사이의 보간 프레임을 생성하는 단계를 포함할 수 있다.
