Abstract
(EN)
A method of producing an avatar video, the method comprising the steps of: providing a reference image of a person's face; providing a plurality of characteristic features representative of a facial model X0 of the person's face, the characteristic features defining a facial pose dependent on the person speaking; providing a target phrase to be rendered over a predetermined time period during the avatar video and providing a plurality of time intervals t within the predetermined time period; generating, for each of said times intervals t, speech features from the target phrase, to provide a sequence of speech features; and generating, using the plurality of characteristic features and sequence of speech features, a sequence of facial models Xt for each of said time intervals t.

L'invention concerne un procédé permettant de produire une vidéo d'avatar, ledit procédé comprenant les étapes consistant à : fournir une image de référence du visage d'une personne ; fournir une pluralité de traits caractéristiques représentant un modèle facial X0 du visage de la personne, les traits caractéristiques définissant une pose faciale dépendant de la personne qui parle ; fournir une phrase cible devant être restituée sur une période prédéterminée pendant la vidéo de l'avatar et fournir une pluralité d'intervalles de temps t dans la période prédéterminée ; pour chacun desdits intervalles de temps t, générer des caractéristiques vocales à partir de la phrase cible afin de fournir une séquence de caractéristiques vocales ; et générer, à l'aide de la pluralité de traits caractéristiques et de la séquence de caractéristiques vocales, une séquence de modèles faciaux Xt pour chacun desdits intervalles de temps t.
