Abstract

The embodiment of the invention provides a cross-age face recognition method and device. The method comprises the following steps: inputting a to-be-recognized face picture into a picture generation model, and obtaining generated pictures of a plurality of age groups corresponding to the to-be-recognized face picture; respectively inputting the to-be-recognized face picture and each generated picture into the basic feature extraction model and the feature extraction model of each age group, and outputting basic face features and face features of each age group; obtaining a feature vector according to the basic face features and the face features of each age group; and obtaining a recognition result of the to-be-recognized face picture according to the feature vector and a pre-obtained facelibrary. The embodiment of the invention provides a cross-age face recognition method and device. According to the cross-age face recognition method and device, the faces of different age groups aregenerated, the features of the faces in the face picture to be recognized and the generated features of the faces of different age groups are extracted respectively and fused, face recognition is conducted according to the fused face features, and the recognition accuracy of cross-age face recognition can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a method and device for cross-age face recognition. Background technique [0002] As an important biometric identification technology, face recognition has been more and more widely used. However, the recognition rate of face recognition is greatly affected by age. In face recognition, the face differences between different individuals are often smaller than the face differences of the same individual in different situations (such as different ages). [0003] The current cross-age face recognition generally converts faces of different ages into representations of one or more fixed ages by synthesizing faces, and then performs face recognition. Since the span between different ages is as long as several years or even decades, training the face recognition model based on the above method requires a very large amount of data, and face data collection cannot meet ...
