Fast Fourier transform for fingerprint enhancement and features extraction with adaptive block size using orientation fields
Extracting minutiae from a digital fingerprint is a crucial step in a fingerprint-based recognition systems. This work deals with poor-quality fingerprint images containing broken ridges. The enhancement stage connects broken ridges and is essential for extracting correct minutiae. We use a FFT vari...
