Abstract
(EN)
A method, apparatus and device for detecting a dynamic facial expression, and a storage medium. The method comprises: acquiring at least two frames of facial images in a video stream (S1010); according to key point coordinate information sets in the at least two frames of facial images, determining a facial state sequence (S1020); and comparing the facial state sequence with a pre-set dynamic expression sequence to determine a dynamic facial expression (S1030).
(FR)
L'invention concerne un procédé, un appareil et un dispositif de détection d'expression faciale dynamique, et un support de stockage. Le procédé consiste à : acquérir au moins deux trames d'images faciales dans un flux de vidéo (S1010) ; selon des ensembles d'informations de coordonnées de point clé dans les au moins deux trames d'images faciales, déterminer une séquence d'états faciaux (S1020) ; et comparer la séquence d'états faciaux avec une séquence d'expression dynamique prédéfinie pour déterminer une expression faciale dynamique (S1030).
(ZH)
一种人脸动态表情的检测方法、装置、设备及存储介质。该方法包括:获取视频流中的至少两帧人脸图像(S1010);根据所述至少两帧人脸图像中关键点坐标信息集,确定脸部状态序列(S1020);比较所述脸部状态序列和预设的动态表情序列确定脸部动态表情(S1030)。
