Robot Control Using FITkit
Novotný, Tomáš ; Orság, Filip (referee) ; Rozman, Jaroslav (advisor)
This paper deals with the teoretical background, design and implementation of the remote controlled robot, which is shipped with various sensors. Work is based on the available devices. FITkit is used for controlling sensors, motors and communication with the PC at the robot side. The different interfaces are used by almost every sensor. These are the I2C bus, PWM or analog signals. The biggest part of the controlling is done by the FITkit using programming C language. The FPGA is used just for the communication over the COM port. Later expansion was in the mind during the design and implementation. The result of this work is remote controlled robot with the sonars, compass, accelerometer and optical encoders.

Road Recognition for Visual Navigation of Mobile Robot
Šeda, Jan ; Orság, Filip (referee) ; Marvan, Aleš (advisor)
In recent years, a significant amount of attention has been given to the development of robust road detection algorithms using color monocular vision. Artificial neural networks are often used in order to deal with this complex issue because of their ability to find complex relationships between inputs and outputs. However, the essential task is to choose suitable features extracted from input visual data. In this thesis, the proposed combination of extracted features aims at the problem of robust road detection. The adaptation ability of neural network is also utilized to overcome the difficulties with variable road texture and shadows. Several experiments have been conducted to verify the presented approach.

Artificial Intelligence in Bang! Game
Kolář, Vít ; Lodrová, Dana (referee) ; Orság, Filip (advisor)
The goal of this master's thesis is to create an artificial intelligence for the Bang! game. There is a full description of the Bang! game, it's entire rules, player's using strategy principles and game analysis from UI point of view included. The thesis also resumes methods of the artificial intelligence and summarizes basic information about the domain of game theory. Next part describes way of the implementation in C++ language and it's proceeding with use of Bayes classification and decision trees based on expert systems. Last part represent analysis of altogether positive results and the conclusion with possible further extensions.

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.

Application for Video Tracking
Borek, Martin ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
Předložená bakalářská práce pojednává o implementaci aplikace Video Anonymizer. Tato aplikace sleduje objekty ve videu a upravuje jejich vzhled. Práce se zabývá zpracováním videa s použitím knihovny FFmpeg, kde se zaměřuje především na vyhledávání snímků. Soustřeďuje se také na sledování více objektů, úpravu jejich trajektorií a na jejich anonymizaci; upřednostňovaný způsob anonymizace je rozmazání objektu. Dále je zde rozebráno vytváření vícejazyčného uživatelsky přívětivého grafického uživatelského rozhraní s pomocí knihovny QT. Při testování uživatelské přívětivosti tohoto grafického uživatelského rozhraní bylo zjištěno, že aplikace je snadno ovladatelná již při jejím prvním použití. Také bylo ověřeno, že uživatelská nápověda obsahuje všechny potřebné informace a je snadno dostupná přímo z aplikace.

Software for Biometric Recognition of a Human Eye Iris
Maruniak, Lukáš ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
In my thesis, I focus on the task of recognizing human iris from an image.In the beginning, the work deals with a question of biometrics, its importance and basic concepts, which are necessary for use in following text. Subsequently process of human Iris detection is described together with theory of evolution algorithms. In the implementation part, is described the design of implemented solution, which uses evolution algorithms, where is emphasis on correct pupil and iris boundary detection.

Mobile Robot Localization Using Camera
Vaverka, Filip ; Orság, Filip (referee) ; Rozman, Jaroslav (advisor)
This thesis describes design and implementation of an approach to the mobile robot localization. The proposed method is based purely on images taken by a monocular camera. The described solution handles localization as an association problem and, therefore, falls in the category of topological localization methods. The method is based on a generative probabilistic model of the environment appearance. The proposed solution is capable to eliminate some of the difficulties which are common in traditional localization approaches.

Automatic Segmentation of Cardiac Tissue Movement from Ultrasound Record
Munzar, Milan ; Orság, Filip (referee) ; Mráček, Štěpán (advisor)
This thesis describes design and implementation of method, which determines beginning of heart beats in echocardiographic record. Design of this method is built around pyramidal Lucas-Kanade algorithm and fast Fourier transform. This method is implemented in C++ language with OpenCV and FFTW libraries. Analysis of the implementation has shown, that this method is sensitive to anomalies in echocardiographic record. This method is developed as a part of the project for an analysis of echocardiographic records for st. Anna hospital at Brno.

Dynamic Template Adjustment in Continuous Keystroke Dynamics
Kulich, Martin ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
Dynamika úhozů kláves je jednou z behaviorálních biometrických charakteristik, kterou je možné použít pro průběžnou autentizaci uživatelů. Vzhledem k tomu, že styl psaní na klávesnici se v čase mění, je potřeba rovněž upravovat biometrickou šablonu. Tímto problémem se dosud, alespoň pokud je autorovi známo, žádná studie nezabývala. Tato diplomová práce se pokouší tuto mezeru zaplnit. S pomocí dat o časování úhozů od 22 dobrovolníků bylo otestováno několik technik klasifikace, zda je možné je upravit na online klasifikátory, zdokonalující se bez učitele. Výrazné zlepšení v rozpoznání útočníka bylo zaznamenáno u jednotřídového statistického klasifikátoru založeného na normované Euklidovské vzdálenosti, v průměru o 23,7 % proti původní verzi bez adaptace, zlepšení však bylo pozorováno u všech testovacích sad. Změna míry rozpoznání správného uživatele se oproti tomu různila, avšak stále zůstávala na přijatelných hodnotách.

Mobile Robot Navigation
Goldmann, Tomáš ; Luža, Radim (referee) ; Orság, Filip (advisor)
When we look at the eld of robotics we nd that exist a lot of types of robots. Some of tham use location navigation and global navigation for their work. This work aims to map options of location navigation and description of basic technique which used. Especially, we will deal with algorithms which work with optical sensors, for example camera, stereocamera or laser which scan medium. Practise section this work is focused on the proposal and implementacion algorithm which working with local navigation for robot's return to the starting position. All this work is connecting with tracked robot which formed in the framework one of project realization at Faculty of information technology.
