Analysis of Fingerprint Quality Assessment Systems
Dejmal, David ; Pernický, Radim (referee) ; Kanich, Ondřej (advisor)
The aim of this work is to improve the process of determining fingerprint quality by Fingerprint Quality Visualizer (FQV). Mutual comparison of existing programs NIST Fingerprint Image Quality 2.0 and Neurotechnology VeriFinger has proved that FQV is worse in processing of extremely small fingerprints. Therefore, the procedure which estimates the number of minutiae in fingerprint based on its real size has been designed and implemented as an improvement. The final testing has proved that the implemented method works for the selected fingerprint collection. This approach can be an alternative to complex searching and accurate minutiae counting.

Methodology of Fingerprint Image Quality Measurement
Oravec, Tomáš ; Drahanský, Martin (referee) ; Kanich, Ondřej (advisor)
This thesis deals with the problem of methodology of fingerprint image quality measurement. The first task was to analyze already existing software used for fingerprint quality measurement called NFIQ (NIST Fingerprint Image Quality), evaluate its performance and identify weaknesses. In order to eliminate discovered NFIQ weaknesses, different fingerprint quality estimation methodology was introduced, and its results were compared to other methodologies.
