Generation of Spoof Effects into Synthetic Fingerprints from SFinGe Generator
 Vrábľová, Žofia ; Drahanský, Martin (referee) ; Kanich, Ondřej (advisor)
The goal of this thesis is to create application to generate spoof effects into synthetic fingerprints from the SFinGe generator. Spoof effects chosen for this thesis are air bubbles, unnatural overall shape and clear external contours of fingerprint. Those effects were analyzed, methods to generate these effects were designed and then implemented. According to testing, generation of implemented methods led to reduction in quality of fingerprint images. Score gained in a commercial tool decreased by 49.37 % in average and image quality evaluated by the method designed in Ing. Oravec's thesis decreased by 6.18 % in average,  when the combination of all implemented spoof effects was generated.
