Path Finding in the Vector Data in OpenStreetMap Project
Adamček, Adam ; Procházka, Boris (referee) ; Váňa, Jan (advisor)
Pathfinding services are nowadays often used by people to plan a route through an unknown area. This bachelor's thesis deals with designing and implementation of an application which is able to search in free map data provided by the OpenStreetMap project and visualize resulting paths. During the search, not only the way types, but the selected transport type and the attributes of the eventual route will be taken into account as well. The work also contains an analysis of the OSM format and the proposal of a custom, more compact format useful for storing the preprocessed data. Eventually, the implemented application's performance is tested and its output is compared with other commonly used routing solutions.

Design and Implementation of Functional Units of an Application for Demonstration of Image Processing Methods
Fadrhonc, Pavel ; Váňa, Jan (referee) ; Orság, Filip (advisor)
The thesis is dealing with implementation of IMPRODEMO image processing application. Author has used existing image processing libraries and has implemented complex application with modern user interface. In order to develop the application, he used framework WPF, method for developing application using tests called Test Driven Development, design pattern MVVM and MEF tool for easy integrating of extensions. Chapter two deals with these technologies and methodologies and describes them. Third chapter describes design of application and presents class diagrams. Fourth chapter describes test driven development and particular pitfalls that emerged from using this methodology. Fifth chapter presents the mean of integrating code written in C++ language into .NET framework and into C# language. At the end, whole work is summarized, resuls are defined and possibilities of resuming and extending the work are proposed.

Liveness Detection on Fingers Using Vein Pattern
Dohnálek, Tomáš ; Váňa, Jan (referee) ; Drahanský, Martin (advisor)
Tato práce se zabývá rozšířením snímače otisků prstů Touchless Biometric Systems 3D-Enroll o jednotku detekce živosti prstu na základě žil. Bylo navrhnuto a zkonstruováno hardwarové řešení s využitím infračervených diod. Navržené softwarové řešení pracuje ve dvou různých režimech: detekce živosti na základě texturních příznaků a verifikace uživatelů na základě porovnávání žilních vzorů. Datový soubor obsahující přes 1100 snímků jak živých prstů tak jejich falsifikátů vznikl jako součást této práce a výkonnost obou zmíněných režimů byla vyhodnocena na tomto datovém souboru. Na závěr byly navrhnuty materiály vhodné k výrobě falsifikátů otisků prstů umožňující oklamání detekce živosti pomocí žilních vzorů.

Support of Mapping by Image Processing
Jaroš, Ján ; Herman, David (referee) ; Váňa, Jan (advisor)
This bachelor's thesis deals with methods of detection of selected objects in video and with importing these objects into OpenStreetMap central database based on their geographic location. It focuses mainly on recognition of road signs. First section briefly describes some of the most widely used methods and OpenStreetMap project itself. In the following chapters is given a more detailed overview of used methods of proposed system, its implementation and testing. The conclusion contains evaluation of whole work and the possible improvements are listed here.

Car Licence Plate Detection and Recognition
Kovaříček, Roman ; Procházka, Boris (referee) ; Váňa, Jan (advisor)
This bachelor thesis deals with finding the license plates in the image and pattern recognition. Work describes short history of the state license plates. It deals with also the current state license plates and their problems. It analyzes the process of image segmentation and follow evaluation of selected areas. A part of the work is design and implementation of algorithms that solve candidate search areas or characters. The final step is the recognition of individual characters and display the user with details of the result.

Face Detection and Identification
Konôpková, Júlia ; Drahanský, Martin (referee) ; Váňa, Jan (advisor)
This work is focused on the problematic of face detection and identification in photography. The introduction is devoted to the most popular methods with briefly descriptions of their principles and rules. Within the practical part of this work we implement and test on free available databases the several of these methods. In the conclusion we evaluate the results and addition of this whole work.

GPS Data Processing Software
Kohoutek, Pavel ; Orság, Filip (referee) ; Váňa, Jan (advisor)
The aim of the thesis is to suggest and implement an application for processing data about absolved tracks in GPX format. The application displays tracks on map layers, offering the possibility of editing the tracks, naming points on the tracks and adding photographs. A whole scale of statistic data is available for each track, including elevation and speed profile graph. Moreover, the application enables users to prepare and generate a presentation including photographs and map screenshots. The theoretical part of the thesis deals with GPS navigation system, ways of recording routes (tracks), map data and application suggestion. The aim of the practical part is to implement the suggested solution and test it.

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.

Search for the Optimal Path in the Terrain
Váňa, Jan ; Janeček, Petr (referee) ; Drahanský, Martin (advisor)
Simulation systems based on artificial intelligence often have to solve the problem of finding a way between two places for an object controlled by a computer. This article deals with a development of such a module for already existing simulation system, which is able to find the best way for any object if this is existent.

Detached house with project office
Váňa, Jan ; Kovářová, Hana (referee) ; Brzoň, Roman (advisor)
The subject of this bachelor’s thesis is a newly bulit family house with a design office. The building consists of two main parts. Both parts have its own entrance and are not interconnected. The first part of the building, a two storey family house, is designed for a family of four. The design office is a single-storey building intended for 6 employees and an owner of the building. The structure is based on strip foundations made of plain concrete. The walls and ceilings are made of the Heluz system. The perimeter walls are insulated with ETICS mineral wool insulation composite system. The building has a flat roof with an asphalt waterproofing system.
