Abstract

Objective To establish a digital system for forensic identiifcation of the palatal rugae and evaluate its application effects. Methods High-resolution digital images of the palatal rugae were harvested under the standard condition and processed including data collection, noise reduction, contrast enhancement, image segmentation, feature extraction, edge detection, and information matching. Apply an MATLAB software system to develop a digital system for forensic identiifcation of the palatal rugae ,and its application effects were evaluated. Results A digital system for forensic identification of the palatal rugae was successfully established. The digital system had an accuracy rate of 100%. Conclusion Establishing a digital system for forensic identiifcation of the palatal rugae provides a novel method for forensic identiifcation.
