Abstract
(EN)
A comparison method based on multiple facial images, an apparatus and an electronic device, the method comprising: acquiring multiple facial images of a target subject (S102); selecting from the multiple facial images a first facial image having the highest quality score and adding same to a candidate image set (S104); when the number of images in the candidate image set is less than a preset number, cyclically selecting from the multiple facial images a second facial image having the largest average difference between a preset parameter and a facial image in the candidate image set so as to add the second facial image into the candidate image set (S106); and performing comparison with a copy facial image of the target subject on the basis of the facial images in the candidate image set (S108).
(FR)
L'invention concerne un procédé de comparaison basé sur de multiples images faciales, un appareil et un dispositif électronique. Le procédé comprend les étapes consistant à : acquérir de multiples images faciales d'un sujet cible (S102) ; sélectionner parmi les multiples images faciales une première image faciale ayant le score de qualité le plus élevé et l'ajouter à un ensemble d'images candidates (S104) ; lorsque le nombre d'images de l'ensemble d'images candidates est inférieur à un nombre prédéfini, sélectionner cycliquement parmi les multiples images faciales une seconde image faciale ayant la différence moyenne la plus grande entre un paramètre prédéfini et une image faciale dans l'ensemble d'images candidates de façon à ajouter la seconde image faciale à l'ensemble d'images candidates (S106) ; et effectuer une comparaison avec une copie d'image faciale du sujet cible sur la base des images faciales de l'ensemble d'images candidates (S108).

一种基于多帧脸部图像的比对方法、装置和电子设备,该方法包括:采集目标对象的多帧脸部图像(S102);从所述多帧脸部图像中选择质量分最高的第一脸部图像加入候选图像集合(S104);当所述候选图像集合中的图像个数小于预设数量时,循环从所述多帧脸部图像中选择预设参数与所述候选图像集合中的脸部图像之间的平均差距最大的第二脸部图像,以加入到所述候选图像集合中(S106);基于所述候选图像集合中的脸部图像与目标对象的留底脸部图像进行比对(S108)。
