Human age classification via face images: a survey

Abstract

Human face shows different patterns on the face for particular age class. These ageing patterns on the human faces can be directly used for developing age based systems. Computer based age classification via face images become an interesting topic recently because of their real world applications such as electronic customer relationship management, security and surveillance, etc. In this paper, the detailed survey has been made on the techniques and algorithms developed by researchers for age classification via face images. Comparative study has been done in this paper on existing age classification methods on the basis of pre-processing techniques, ageing feature extraction methods, age classifiers, system performances and databases used for evaluation of system. Future research directions related to the topic of automatic human age classification via face images are also mentioned in this paper.
