Adaptive boosted spectral filtering for progressive fingerprint enhancement

| Hi-index | 0.00 |
The proposed fingerprint enhancement algorithm utilizes power spectrum in spatial-frequency domain. The input fingerprint is partitioned and assessed as high/low quality zone by using signal-to-noise ratio (SNR) approach. For high quality zone, signal spectrum with noise suppression is used to shape an enhanced filter in frequency domain. Then, this algorithm feed neighboring enhanced zone back in order to repair unreliable low quality region. The proposed algorithm out-performs Gabor and STFT approaches by fingerprint matching experiments on FVC2004 Db2 and Db3.
