Abstract
(EN)
Disclosed are a multi-user video special effect adding method and apparatus, a terminal device and a storage medium. The method comprises: in multiple image frames matching special effect adding intervals in a video, identifying at least one human joint point of target users matching the special effect adding intervals; calculating motion feature parameters of the target users according to position information of the at least one human joint point of the target users; where the at least one human joint point, identified in an image frame selected from the multiple image frames, of the target users satisfies a pre-set joint action condition, taking the selected image frame as a target image frame, and acquiring video special effects and special effect adding information, and adding the video special effects to a video position associated with the target image frame in the video; and calculating motion score information of each of the users, and adding the motion score information to a motion score settlement position matching the video.

L'invention concerne un procédé et un appareil d'ajout d'effets spéciaux vidéo associés à de multiples utilisateurs, un dispositif terminal et un support de stockage. Le procédé comprend les étapes consistant à : dans de multiples trames d'images correspondant à des intervalles d'ajout d'effets spéciaux dans une vidéo, identifier au moins un point d'articulation du corps humain d'utilisateurs cibles correspondant aux intervalles d'ajout d'effets spéciaux ; calculer des paramètres caractéristiques des mouvements des utilisateurs cibles en fonction d'informations sur la position dudit au moins un point d'articulation du corps humain des utilisateurs cibles ; lorsque ledit au moins un point d'articulation du corps humain des utilisateurs cibles, ledit point étant identifié dans une trame d'image sélectionnée parmi les multiples trames d'images, satisfait une condition d'action de l'articulation prédéfinie, considérer la trame d'image sélectionnée comme une trame d'image cible, acquérir des effets spéciaux vidéo et des informations d'ajout d'effets spéciaux et ajouter les effets spéciaux vidéo en une position vidéo associée à la trame d'image cible dans la vidéo ; puis calculer des informations sur des scores de mouvements de chacun des utilisateurs et ajouter les informations sur des scores de mouvements en une position de détermination de scores de mouvements correspondant à la vidéo.
