Gestures in User Interfaces
Bednář, Luboš ; Beran, Vítězslav (referee) ; Mlích, Jozef (advisor)
This master thesis deals with the use of gestures in user interfaces. The goal of this thesis is to create library for hand tracking and gesture recognition in real time. For hand tracking was choosen algorithm Flock of Features. Classification of gestures is done by using algorithm DTW. This thesis also contains stage design, design and implementation of a system that uses this library. Within the tests was tested control of various application using this library.

Navigation System for Pilots
Kryl, Jan ; Vlk, Jan (referee) ; Mlích, Jozef (advisor)
This bachelor thesis concerns design and creation of a navigational system as a tool for pilots of gliders, paragliders, helicopters or ultralight planes. Rendering of map basis is critical part for realization of this project. The way of this rendering is described in the paper, including theory concerning the topic. The paper also contains description of draft and implementation of application.

Object Tracking in Video Sequences
Mlích, Jozef ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
In this master thesis, image processing methods and methods for statistical modeling of motion are presented. First, description methods of image processing, such as background subtraction method used for object detection, are presented. Next, description of morphological operations, such as dilatation and erosion, is done. Finally, methods for statistical modeling, such as Kalman filter and particle filters, are shown.

Unified Network Authentication for Linux
Zůna, Pavel ; Drozd, Michal (referee) ; Mlích, Jozef (advisor)
Tato práce se zabývá návrhem a implementací řešení pro jednotnou síťovou autentizaci pro operační systém Linux založeného na integraci systémových démonů WinBind a SSSD. Cílem je navrhnout takové řešení, které umožní autentizaci Linuxových klientů do domén spravovaných adresářovými službami Windows Active Directory a domén spravovaných adresářovými službami dostupnými na Linuxu současně. První dvě kapitoly seznámí čtenáře s autentizačními mechanizmy a technologiemi, které se pro tyto účely použivají na operačních systémech Windows a Linux. Třetí kapitola se zabývá jádrem práce a vysvětluje rozhodnutí učiněná při návrhu implementovaného řešení. Samotná implementace je pak popsána v kapitole čtyři. Poslední kapitoly popisují experimenty a testování pro vybrané případy užití s návrhy a popisem možných rozšíření do budoucna.

Gesture Recognition
Svoboda, Tomáš ; Mlích, Jozef (referee) ; Hradiš, Michal (advisor)
This Bachelor's thesis is engaged in recognition hand gestures. The advantages and disavantages of various color models for skin color detection are discussed here. Skin is detected by look-up table. Look-up table is created from histogram of skin color and optional from Gaussian distribution, whose parameters are estimated from histogram. Hidden Markov models are used for gesture classification. The HTK toolkit have been used for working with the models. Own decoder of Hidden Markov models based on Viterbi algorithm was created for real-time gesture recognition. Several experiments were accomplished with data sets for 4 gestures. The results of the experiments are very good.

HDR Tone-Mapping
Vančura, Jan ; Mlích, Jozef (referee) ; Seeman, Michal (advisor)
This thesis concerns with the introduction to the problematics of images with high dynamic range (HDR) and possibilities of HDR images compression options for display on devices with a low dynamic range (LDR). In the introduction is described historical evolution of recording of reality. It is focusing towards point of view of physics, human visual perception and digital recording. There are described the ways of generating and holding of HDR images. The thesis is corncerned to the techniques of HDR compression, it means the tone-mapping. The different techniques of tone-mapping are explained and specific aproach is targeted to the gradient domain high dynamic range compresion.

Music Streaming Service
Škultéty, Erik ; Musil, Petr (referee) ; Mlích, Jozef (advisor)
This thesis deals with music streaming subject and implementation of a model application for MeeGo based platforms. Application relies on services provided by RTP protocol. These services are supplied by GStreamer framework plugins. Cloud computing topic is also discussed later in this thesis, focussing mainly on the SaaS method. Finally, a server part which provides a list containing available radios, needed by the client part, as well as the possibility for users to add new radios into the database, is described.

MediaDiff - Diff for Static Images
Brothánek, Jan ; Mlích, Jozef (referee) ; Chmelař, Petr (advisor)
This bachelor's thesis focuses on comparison of digital documents, especially static images. This paper presents algorithms, which are usable for general data comparison and also specific algorithms major in image data comparison. We introduce possibilities of document comparison which are now available for users. On the basis of this current situation, a prototype of new modular application MediaDiff for various documents comparison is designed and implemented. We describe in detail each stage of the application development, problems which had arisen and their solutions. The possibilities of future development of the application are discussed.

Support for Fingerprint Authentication
Bartoň, Jaroslav ; Beran, Vítězslav (referee) ; Mlích, Jozef (advisor)
The goal of the thesis is the finger-print authentication support within the Linux operating system and the K Desktop Environment (KDE). Theoretical part of the thesis firstly explains main IT security terms and ways to proof the identity. Secondly it describes biometric systems and types of processed biometric characteristics. Lastly the features of finger-prints, their markants as well as types of scanners used in scanning the finger-prints and ways to analyze the scanned material have been elaborated. Practical solution part of the thesis develops and establishes finger-print management application and plugin for KDM graphics login manager.
