Editor for WSQ Format of Fingerprint Images for Demonstration
Németh, Patrik ; Rydlo, Štěpán (referee) ; Kanich, Ondřej (advisor)
The goal of this thesis is to design and implement an application suitable for demonstrating the individual steps of fingerprint analysis, and which is able to automatically process fingerprints stored in the most widely used formats for storing fingerprint imagery, such as WSQ, PNG and JPEG 2000. In this thesis special attention was given to automatic processing methods and analysis of fingerprint imagery. It also offers an overview of the WSQ format and of its comparison to JPEG 2000. The output of this work is a graphical application capable of demonstrating individual steps of widely used methods of fingerprint imagery processing and analysis. The application implements Gabor filtering, line thinning based on the Zhang-Suen method, and other methods of fingerprint processing. With some error, it is capable of detecting minutiae, singularities and the class of a fingerprint. Some of the processing parameters may be modified by the user via the graphical interface. Processed images can be exported in various image formats.

Analysis of Fingerprint Spoofs Made from Various Materials
Sláma, Vladimír ; Drahanský, Martin (referee) ; Kanich, Ondřej (advisor)
The goal of the work is production of fingerprint spoofs from various materials and develop- ment of algorithm, that analyzes them. Production of fingerprint spoofs is based on casting using printed circuit board (PCB) and other molds. For fingerprint spoofs these materials were used: Herkules, plasticine, Funny gummy, wax, Moody putty and liquid latex. For analysis of the differencies between spoof and the real fingerprint Harris detector was used and then the difference score is counted based on points of interests found. Results are compared with evaluation from VeriFinger software, that can measure matching score of two fingerprints. In most of the cases, the results have same trends when compared.

A fingerpring database
Kubát, Jaroslav ; Babka, Martin (advisor) ; Lokoč, Jakub (referee)
The main goal of this thesis is to provide full description of an implementation of an application that is supposed to be a complex dactyloscopic database tool. The text is divided into parts according to the functional blocks of the application. The parts are namely processing of input fingerprint, the minutiae point analysis, the description of minutiae representation, the database and index structure described with its operations. Usually we describe multiple algorithms for a single task. In this case we provide their comparison. At the end of this thesis, there is a user manual describing the main usage scenarios.
