Dental work extraction for different radiographic Images in human Forensic Identification

Dental biometrics is used to identify the individuals in the forensic domain. Forensic identification is used to identify the person by comparing postmortem and ante mortem dental images. The dental radiograph image provides the information about teeth, tooth contours and in addition to that dental work (DW) is one of the notable issues for forensic identification. This dental work includes crown filling, root canal and crown mineralization for tooth. In this paper addresses the dental work identification for different radiographic images such as bitewing, periapical and panoramic dental images with Mahalanobis distance based matching. The proposed system contains preprocessing, feature extraction and matching. Experimental evaluation gives the satisfied results which will abet for dental biometrics.
