Abstract
(EN)
Disclosed are a video special effect adding method and apparatus, a terminal device and a storage medium. The method comprises: acquiring at least one image frame in a video, and identifying at least one target human joint point of a user in the image frame; where the position of the identified target human joint point in the image frame satisfies a joint position condition in a pre-set video special effect condition, taking the image frame as a target image frame, and acquiring at least two consecutive image frames before the target image frame; according to a target human joint point identified in the at least two consecutive image frames, determining a motion state of the target human joint point; where the target human joint point satisfies a joint action condition, acquiring a video special effect matching the video special effect condition; and adding, at the video position associated with the target image frame in the video, the video special effect matching the video special effect condition.

La présente invention concerne un appareil et un procédé d'ajout d'effet spécial vidéo, un dispositif terminal et un support d'informations. Le procédé consiste : à acquérir au moins une trame d'image dans une vidéo, et à identifier au moins un point d'articulation humain cible d'un utilisateur dans la trame d'image ; la position du point d'articulation humain cible identifié dans la trame d'image satisfaisant une condition de position d'articulation dans une condition d'effet spécial de vidéo prédéfinie, à prendre la trame d'image en tant qu'une trame d'image cible, et à acquérir au moins deux trames d'image consécutives avant la trame d'image cible ; conformément à un point d'articulation humain cible identifié dans lesdites deux trames d'image consécutives, à déterminer un état de mouvement du point d'articulation humain cible ; le point d'articulation humain cible satisfaisant une condition d'action d'articulation, à acquérir un effet spécial vidéo correspondant à la condition d'effet spécial vidéo ; et à ajouter, au niveau de la position vidéo associée à la trame d'image cible dans la vidéo, l'effet spécial vidéo correspondant à la condition d'effet spécial vidéo.
