A new digital intraoral X-ray image analysis system for objective personal identification

  • 88 Accesses

Abstract

Objectives

To develop a new image processing system for personal identification that applies phase-only correlation (POC) to digital intraoral X-ray images.

Methods

We developed a personal identification analysis system that applies POC. Amplitude components were extracted by applying fast Fourier transform to digital intraoral X-ray image data. The amounts of rotation and magnification of the images was transformed into a translational shift via image processing of the obtained amplitude components. The position shift of the images caused by these translational shifts was corrected by applying POC to the images after the rotation and magnification were corrected. The accuracy of the system was evaluated visually by using digital image subtraction images of the reference image and a comparison image processed by the system.

Results

The results showed that this system corrects the position of the images for translational shift and rotational displacement. The magnification of images caused by the translational shift of the imaging plate was also corrected to within a specific admissible range. The system has a wide tolerance for images with density differences.

Conclusions

This image processing system is effective for objective personal identification.
