This paper presents human eye-iris registration and matching in an iris database using phase-only correlation techniques. Two modified phase-only correlation techniques with efficient registration results are used: the rectangle band limited phase-only correlation method (BPOC) and an elliptic limited ...
In this work, we present an optical flow algorithm with a highly reduced set of motion vector candidates that are obtained by the Phase-Only Correlation function. For each candidate and each pixel, we estimate the cost of assigning the candidate vector to that pixel using a sophisticated filter...
The BLPOC method is more robust to the noise and can provide a sharper peak to distinguish between the genuine and impostor matching than the original phase-only correlation (POC). The experimental results on FVC2002 fingerprint databases show that the proposed algorithm is effective 展开 关键词:...

This paper proposes an efficient dental radiograph registration algorithm using Phase-Only Correlation (POC). The use of phase components in 2D (two-dimensional) discrete Fourier transforms of dental radiograph images makes it possible to achieve highly robust image registration and recognition. The prop...
Values of the peak correlation spot power versus both rotation angle and scale factor are presented for both filter types. Several theorems are derived for calculating the optical efficiency of any filter in both input space and frequency space.关键词:...

In this paper, we propose a novel approach for palmprint recognition, which combine band-limited phase-only correlation method and directional representation of palmprint. We also exploit peak-to-sidelobe ratio as the similarity measure. The results of e
In order to eliminate the interference of these factors, we propose a method based on phase-only correlation (POC) to estimate the relative arrival times of microseismic events. The proposed method includes three main steps: (1) The SNR of the records is improved via time-frequency transform,...
