Advances of Age Progression Based Cross-Age Face Recognition

Cross-age face recognition is one of the most difficult problems in face recognition at present. Face features will change with age, resulting in a decrease in recognition accuracy. The face recognition based on the generated aging images obtained from aging models is a popular solution for this problem. With the widespread application of computer technology and deep learning, the authenticity, aging effect, and algorithm efficiency of face aging have been significantly improved. This paper systematically reviews the current research status of cross-age face recognition based on aging models. The aging methods are sorted out in detail, the method evolution of aging models and the advantages and disadvantages of various methods are systematically introduced, and the existing model evaluation methods are summarized. In addition, the existing datasets that can be used for cross-age face recognition are introduced in detail, and a comparative analysis is made in terms of data volume, age span, age accuracy, and use of the data set. For the purpose of practical applications, the problems to be solved in cross-age face recognition based on the aging model are analyzed and discussed. Moreover, the future research directions are predicted and prospected.
