Problems solved by technology

[0003] However, related technologies are mainly based on image features for feature comparison. If the face image to be recognized is similar to the facial features of the two faces in the face image sample but the gender or race is different, or the above two face images are the same person In the facial images of two different age groups, the above situation cannot be accurately identified by using related technologies, so the accuracy of face recognition needs to be further improved

Abstract

The invention discloses a face identification method and apparatus. The method includes the steps of extracting face characteristic vectors of a face image to be identified by using a convolution neural network model. The face characteristic vectors comprise image characteristics and facial attribute characteristics. Matching degree between the face image to be identified and face images in a face template database is calculated according to the face characteristic vectors, and the identification result of the face image to be identified is determined according to the matching degree. During a face identification process, the face identification accuracy is effectively improved based on comprehensive comparison of the face image characteristics and facial attribute characteristics.

Description

technical field [0001] The present disclosure relates to the technical field of image recognition, in particular to a face recognition method and device. Background technique [0002] Face recognition technology is widely used in identity verification tools related to privacy or security. It mainly includes two parts: facial feature extraction part and feature comparison and matching part. In recent years, with the development of deep learning technology, in the part of facial feature extraction, based on the artificial neural network model, the method of guiding the feature learning of the model through supervision signals has become more and more common, which has effectively improved the accuracy of face recognition. [0003] However, related technologies are mainly based on image features for feature comparison. If the face image to be recognized is similar to the facial features of the two faces in the face image sample but the gender or race is different, or the above ...
