Automatic Age Estimation by Wrinkle Analysis in Biometrics: A Review

Abstract

Recently, age estimation using facial images has become an important factor useful in many potential applications. Using human face as biometric measure, dealing with aging process of an individual has been overlooked since years. An age estimation system is generally composed of feature extraction and classification with the combination of global and local features. Several micro features such as moles, scars, expressions, has been used commonly in face recognition, but due to some anomalies, we use the discriminative power of wrinkles in age estimation processes.
