Abstract: Objective To investigate the feasibility of forensic identification through digital imaging of the palatal rugae. Methods Digital images of the palatal rugae under a particular environment were collected. Rugae Image Identification System was used for collection, noise reduction, augmentation, segmentation, feature extraction, edge detection, and information matching, with each procedure having a corresponding algorithm. After Matlab processing, the matching achievement ratio and matching time of palatal rugae images were recorded. Results Three dentists obtained 100% accurate Results, one case and two cases were not matched respectively by the other two evaluators. Dentists completed computer processing of the images in the shortest time. Conclusion A more rapid and accurate method for forensic identification was successfully achieved through digital imaging of the palatal rugae. The study proposes a new method for forensic identification.
