This paper summarizes a high-accuracy image matching technique called Phase-Only Correlation (POC). The Phase-Only Correlation is an image matching technique using the phase components in 2D Discrete Fourier Transforms (DFTs) of given images. This technique has been successfully applied to a wide range of applications, such as industrial image recognition, passive 3D measurement, biometric authentication, video signal processing, etc. In this paper, we present applications of POC to fingerprint, iris, palmprint, face and dental radiograph recognition. |
