Outline of Final Research Achievements

This project developed fundamental and advanced techniques of Phase-Only Correlation (POC), which is a high-accuracy image matching technique using phase information of Fourier Transform of given images. We applied the developed POC techniques to a wide range of applications, including 3D measurement, video/image processing, machine vision, biometrics and medical image analysis. We also considered the implementation of their algorithms using the state-of-the-art GPUs toward the practical use of the developed techniques. We demonstrated effectiveness of the developed techniques through their practical applications.
