Automatic classification of person by age group
description Automatic age estimation is attracting increasing research interest recently, mainly due to its wide potential applications, which includes forensic medicine, developing group specific human computer interfaces for human-machine system, improving recognition system efficiency on large databases, performing age specific customer analysis and other commercial purposes. Therefore, it is beneficial to explore the traits related to aging and develop a system to automatically estimate a person’s age. In earlier researches, face dimension ratios and wrinkles were used to classify the age group of a person.
