Estimation of Age from Face Images

An important personal trait is human age, can be directly inferred by the different patterns appear on the face. The recently use topics are the computer-based age synthesis and estimation from faces and has the various applications such as in customer relationship management, biometrics, security control, cosmetology. Face recognition is challenging and interesting area in real time applications. An age estimation is the estimation of age from the face image with the exact age in year or the age range. In this paper we survey the complete age synthesis from face images techniques. Existing models, various algorithms, face images databases, protocols, techniques, future discussion are discussed in this paper.
