Abstract: Estimating human age automatically via facial image analysis has lots of potential real-world applications, such as multimedia communication, market intelligence and visual surveillance, and human computer interaction. However, it is still a challenging problem to automatically and effectively estimate human ages. Numerous researchers have worked on this interesting area and proposed different age estimation approaches. In this paper, we present an analysis on various age estimation techniques that were proposed in earlier literature. Also we provide an overview of the age estimation process.
