Fingerprint scanning

By Michal Kubiš


Fingerprints are the oldest and most used form of biometric identification. A critical step is reliable extract minutiae from the fingerprint images. However fingerprint images are rarely of perfect quality, they may be degraded and corrupted due to natural variations in skin and sensing conditions. Thus, image enhancement techniques are necessary prior to minutiae extraction. This work includes implementation of three techniques for fingerprint image enhancement, minutiae extraction and consturction of fingerprint reading device. Experiments are realized with two sets of fingerprints to evaluate the performance of implemented techniques

Topics: minutiae extraction; image enhancement; extrakce markant; Gaborova filtrace; Fourierova filtrace; vylepšování obrazu; Fourier filtration; otisk prstu; Gabor filtering; image scanning; fingerprint; STFT filtering; skenování obrazu; STFT filtrace
