Abstract

The orientation image estimation is a critical step in fingerprint image processing and feature extraction. The computation of local ridge orientation in low quality fingerprints is still a difficult task. A simple and reliable method for estimating the fingerprint orientation image in the frequency domain is proposed. The results of the experiments conducted on a collection of fingerprints, in order to evaluate the performance of the proposed method, are also presented.KeywordsBiometricsFeature extractionFingerprint recognitionSpectral analysis
