A Literature Review on Facial Age Estimation Researches

Face is the unique characteristic of humans that distinguishes between individuals. Every feature on the face can be analyzed to produce demographic information such as gender, age, race, etc. Any such information can be estimated through an automated process, including age. Age estimation through facial images is one of the areas that is still being pursued to deliver accurate values. To better understand facial age estimation, this paper will discuss several things regarding age estimation. First, the factors that can affect the accuracy of predictions, second, the methods used to estimate the age, and then various databases of facial images and information of age at which the picture was taken, and also the parameters that commonly used to measure the accuracy of the estimation results. This review also provides a summary regarding some researches already conducted in age estimation. In the conclusion section, there is a brief about future work that could be done, along with the reason why such research needs to do
