Review on dental image based biometric system

Abstract

A biometric system uniquely identifies a person based on the features captured from the biometric data of that person. A dental biometric system identifies an individual based on their unique dental features obtained from the dental images. With the growth of latest technologies, forensic identification of humans is a vast growing research area. In Dental biometric system, initial step is to perform preprocessing and then to capture the features of dental image. In the final step segmentation and dental matching is done for person authentication. In this paper, we throw light into made to the latest contribution made to this research field. This paper also presents a general frame work of the dental biometric system and the reviews the research work and also considering the technological advancements in the dental biometric field.
