| Outline of Final Research Achievements |
In this project, we have developed automated matching technologies for 2D X-ray images such as dental radiographs, 3D images such as CT and MRI and 2D-3D heterogeneous images using Phase-Only Correlation (POC), which is a high-accuracy image matching technique using phase information of discrete Fourier transform. In addition, we have developed an individual search technology from multi-modal databases combined with dental charts and images. We have demonstrated effectiveness of the developed technologies through performance evaluation using a large-scale dataset.
