Problems solved by technology

However, in the process of aggregation, there are often differences in face poses, expressions, lighting, etc. in the face pictures, which leads to a decrease in the similarity between the feature vectors of the face feature extraction of the same person, and then it appears that the face images that belong to the same person cannot The face pictures are aggregated into one cluster, which greatly reduces the accuracy of face recognition

Abstract

The embodiments of the invention disclose a face identification method and apparatus. First-type characteristics are obtained from pictures comprising human faces, then a distance weight coefficient between two faces is obtained according to the first-type characteristics, a weight similarity between the two faces is obtained by use of the distance between the two faces and the corresponding distance weight coefficient, and finally, according to the weight similarity between the two faces, clustering is performed on the pictures, the pictures belonging to the same person are clustered to form a cluster, and the pictures of the different persons are classified into different clusters. According to the face identification method, the similarity of five sense organs and facial forms of the two faces is taken into consideration, and measurement is also carried out on the similarity of the faces according to the first-type characteristics included in the pictures, such that the face similarity of the same person under different conditions is increased, and the similarity between the faces of different persons can be reduced. Therefore, the face identification method and apparatus can improve the face identification accuracy.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a face recognition method and device. Background technique [0002] Through the face recognition method, the face pictures belonging to the same person in the album can be aggregated into one cluster. However, in the process of aggregation, there are often differences in face poses, expressions, lighting, etc. in the face pictures, which leads to a decrease in the similarity between the feature vectors of the face feature extraction of the same person, and then it appears that the face images that belong to the same person cannot The face pictures are aggregated into one cluster, which greatly reduces the accuracy of face recognition. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides a face recognition method and device to improve the accuracy of face recognition. The embodiment of...
