In order to directly model phase information in frequency domain,the palmprint recognition method based on correlation filter is proposed.Image sub-sampling is first applied to reduce the palmprint space dimensionality.The minimum average correlation energy(MACE) filters based on the training set are designed.Then the training set and test set are correlated with the filters to produce correlation output.The peak-to-correlation energy(PCE) ratio as a match metric is calculated to match the palmprints.The al...
