Abstract

The invention provides a method and a device for face image identification, and a terminal. The method comprises: compressing and storing a face image to be identified and all images in an image library respectively according to a first compression algorithm and a first image quality; creating mixed images of each image in the compressed face image to be identified and the compressed images in theimage library, and compressing the mixed images respectively according to the first compression algorithm and the first image quality; and calculating a matching factor of the compressed mixed image,and determining a recognition result according to the matching factor. According to the invention, the same compression algorithm and image quality are used to compress images before and after the mixed image, the matching factor of the compressed mixed image is calculated, and the recognition result is determined according to the matching factor, thereby solving the problem that the face recognition method in the related art cannot meet the requirements of real-time on-site applications, and thus achieving effects of high identification precision and fast operating speed.

Description

technical field [0001] The present invention relates to the field of image analysis, in particular to a face image recognition method, device and terminal. Background technique [0002] Recently, the newly launched Apple mobile phone (iPhone 10) has added a face recognition (Face Recognition, referred to as FR) function, which has aroused people's attention to face recognition technology again. However, since FR technology is a developing research field, it is not as accurate as fingerprint authentication technology, so its practical application is limited and has not been widely promoted. [0003] Among related technologies, principal component analysis (PCA for short) and linear discriminant analysis (LDA for short) algorithms run fast, but perform poorly in face recognition accuracy. Elastic Bunch Graph Matching (EBGM) algorithm and face pattern byte (Face Pattern Byte, FPB) algorithm based on wavelet face recognition method has excellent performance, but due to the high...
