Dental biometric in human forensic identification

摘要

Use of image processing for biometric systems goes on increasing from last decade. The biometric is a tool used for person identification system. Dental biometric is one of the effective methods used in the forensic science for person identification. This system utilized dental radiography and dental photograph as it provides unique teeth features like shape, contour, dental work like crown, bridges and fillings, the relative distance between neighboring teeth etc. The proposed method consists of three processing stages: image acquisition, preprocessing, feature extraction, dental code formation and matching. The proposed system gives an accuracy of 94% for dental photograph and 96% for dental radiograph.
