| Outline of Final Research Achievements |
In this study, we developed a set of general-purpose image correspondence algorithms based on "high-accuracy correspondence of multidimensional signals based on local phase features represented in multiple resolutions." Through strategic application researches on biometrics, multi-view stereo 3D reconstruction, radar grammetry, and medical image analysis, we have demonstrated the effectiveness of phase-based image correspondence algorithms.
