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.

Biometric fingerprint identification
Dašek, Filip ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
In biometrics we use distinctive physical features for identification and verification of identity. The most famous technique is identification by fingerprints. This technique use unique structure created by papillary lines for unambiguous identification. Thesis contains methods which were created throughout the years for analysis and adjustments of fingerprint. The algorithm is based on compairng two pairs of minitua and calculating transform matrix for correct alignment. Algorithm is tested on dataset created from LivDet databases. Performance of algorithm is represented by value EER which is compared with EERs of other algorithms tested in FVC 2006.

Fingerprints Generator
Chaloupka, Radek ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
Algorithms for fingerprints recognition are already known for long time and there is also an effort for their best optimization. This master's thesis is dealing with an opposite approach, where the fingerprints are not being recognized, but are generated on the minutiae position basis. Such algorithm is then free of the minutiae detection from image and enhancements of fingerprints. Results of this work are the synthetic images generated according to few given parameters, especially minutiae.

Realization of fingerprint scanner
Kovář, Martin ; Sekora, Jiří (referee) ; Mézl, Martin (advisor)
This master’s thesis deals with the issue of scanning human fingerprints, which is currently very topical and represents the most widespread biometric technology. The theoretical part of the work acquaints the reader with basics of dactyloscopy and biometrics and concerns technologies used for fingerprinting, image preprocessing methods and commercially available contactless optical scanners. The practical part is a realisation of a contactless optical scanner based on a Raspberry Pi minicomputer, implementation of preprocessing algorithms in Python and testing of the device from the perspective of image quality.

Basic fingerprint liveness detection
Horák, Tomáš ; Smital, Lukáš (referee) ; Kašpar, Jakub (advisor)
Biometric data is unique, safe and often used to protect information. Even in some cases, detectors can be fooled, and therefore liveness is needed to check. This work focuses on the basic recognition of the liveliness of the fingerprint. Only one finger image is used. For perfect recognition, you need to compare the prints, so have more than one print, and that's why this detection is very demanding. Pre-processing was done with a binary segmentation mask. Methods using gray scale ratios, mean, standard deviations or histogram equalization were also used. All the methods were done on the LivDet 2011 database, in the Matlab environment and the goal was to recognize a live fingerprints from a false ones.

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.

Basic fingerprint liveness detection
Horák, Tomáš ; Smital, Lukáš (referee) ; Kašpar, Jakub (advisor)
This work focuses on recognizing fingerprints liveness based purely on software-methods evaluating symptoms from just one fingerprint image. At first in this work was described the issue of biometry as such, comparing the advantages and disadvantages of such systems. Next part deal with more detailed process of fingerprint biometry including papillary lines and overall fingerprints as such. In the next phase, the problems and utilization of both software and hardware methods are discussed, including principles of individual approaches. This part is followed by a selection of used fingertip symptoms. This is followed by the practical part and the LivDet 2011 database, which was used for finger recognition. In the practical part is also described the used neural network capturing minor differences in fingerprints according to 13 symptoms.

Detection of Interrupted Friction Ridges of a Fingerprint and Their Reconstruction
Cejpek, Tomáš ; Dvořák, Radim (referee) ; Stružka, Jaroslav (advisor)
This Bachelor thesis describes creating application with graphical user interface for editing a fingerprint ridges. They are interrupted due to dry fingerprint. The proposed algorithm uses Gabor filter for editing fingerprint ridges. He is implemented in C++ and uses a library aimed at work with images OpenCV and Qt application for creating graphical user interface. The thesis is also about testing and evaluating the results of a proposed algorithm for editing fingerprint ridges.
