Extraction of Detailed Information from Plastic Fingerprints
Krsička, Tomáš ; Sakin, Martin (referee) ; Kanich, Ondřej (advisor)
This thesis deals with automatic analysis of plastic fingerprints and extraction of statistic information from them. The application uses a texture highlighting algorithm to separate the area that includes the fingerprint and extracts the width and density of papillary ridges. These values are then converted into mm and appropriately exported. This information can then be used to estimate the age of the owner of the fingerprint. The results of the analysis of most of the data have shown wider ridges in male fingerprints and a growing width of ridges with the age of the owner.

Recognition of Skin Diseases on Fingers of a Human Hand
Šesták, Martin ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
This bachelor thesis deals with the design of methods and application for recognition of the fingerprints from diseased and healthy fingers and the subsequent detection of selected diseases. The first part describes basic principles of biometrics, introduction to fingerprints and their processing, and introduction to the topic of fingerprints affected by skin diseases. The next section describes the implementation of the application and its results. The application was tested on a database of research group STRaDe, from the Department of Intelligent Systems, Faculty of Information Technology, Brno University of Technology, which contains approximately 380 test fingerprints.

3D Fingerprint Model Creation
Pavlík, David ; Váňa, Jan (referee) ; Dluhoš, Ondřej (advisor)
This bachelor thesis deals with acquiring fingerpints, basics of processing fingerprints at biometric systems and 3D model creation techniques. Main aim of this thesis is graphical application that uses fingerprint acquired with 2D fingerprint scanner and then creates 3D model of it. Application does not take curvature of finger into consideration but tries to reproduce height of papillary ridges. It's code is written in C++ with use of cross-platform user interface framework Qt. Besides 3D model creation it allows user to choose accuracy of this model and to export it in two different file formats. Possible use of this application is on the field of fingerprint liveness detection based on sweat pores. Application was tested on 50 real fingerprints and also on two different types of artifical fingerprints.

Fingerprint biometry
Kubica, Roman ; Jiřík, Radovan (referee) ; Fedra, Petr (advisor)
The first part of this thesis deals with principles of evaluation biometric methods of scanning fingerprint images. Classification and description of single methods, separated into groups depending on the algorithm of comparison of template and image from database are included. In the next part is thesis focused on evaluation based on the success of experimental results and description of available databases. The main purpose of this thesis is creation of computer program for identification of fingerprint image in the programming interface MATLAB®. Realized identification algorithm is based on computing of Poincare index and extraction of singular points and minutiae. Performance of the program is tested on generated database and evaluated by index FAR and FRR.
