Augmented User Interface
Zahrádka, Jiří ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This thesis falls into a field of user interface design. It focuses on tangible user interfaces which utilize a camera and projector to augment physical objects with a digital information. It also includes description of calibration of those devices. The primary object of this thesis is the implementation of an augmented user interface for application windows management. The system consists of a stationary camera, overhead projector and movable tangible objects - boards. The boards are equipped with fiducial markers, in order to be tracked in a camera image. The projector displays the conventional desktop onto the table and the tangible objects. For example, application windows can be projected onto some boards, while the windows move and rotate simultaneously with the boards.

Optic disc segmentation in retinal images
Vymazal, Bronislav ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
Cílem této práce bylo vytvořit kompaktní algoritmus sloužící k lokalizaci, segmentaci a sledování optického disku v sekvencích obrazů sítnice. Pro účely lokalizace byla použita nová metoda založena na „fast radial transform“. Segmentace optického disku je založena na klasické metodě Chan-Vese, která byla rozšířena o další prvky a implementována v lokalizované podobě, která umožňuje lépe segmentovat obrazy s vysokou mírou nehomogenity. Pro sledování optického disku v sekvencích obrazů byl využit optický tok založený na Lucas-Kanade algoritmu. Všechny metody byly vyhodnoceny na dvou databázích obrazů s odlišnými charakteristikami. První databází je klasická databáze s vysokým rozlišením. Druhou je pak databáze s nízkým rozlišením a vysokou mírou šumu. Všechny výsledky jsou pak porovnány s referenčními hodnotami a vyhodnoceny.

Detection, Tracking and Classification of Vehicles
Vopálenský, Radek ; Herout, Adam (referee) ; Juránek, Roman (advisor)
The aim of this master thesis is to design and implementation in language C++ a system for the detection, tracking and classification of vehicles from streams or records from traffic cameras. The system runs on the platform Robot Operating System and uses the OpenCV, FFmpeg, TensorFlow and Keras libraries. For detection is used cascade classifier, for tracking Kalman filter and for classification of the convolutional neural network. Success rate for detection is 91.93 %, tracking 81.94 % and classification 63.72 %. This system is part of a comprehensive system, that can moreover calibrate video and measure of vehicles speed. The resulting system can be used for traffic analysis.

Solar Concentrator System with Automatic Tracking System
Žák, Martin ; Sumec, Stanislav (referee) ; Baxant, Petr (advisor)
This master’s thesis is focused on current possibilities of solar energy utilization – especially on concentrating solar power systems – and their optimization using solar tracking systems to maximize energy gain. The thesis also deals with solar position algorithm and offers an Arduino based automatic dual axis solar tracker design which provides various solar devices the ability to pivot using stepper motors, DC motors or servos. The motion might be driven by calculated solar position or by actual illuminance.

Moving Objects Detection in Video Sequences
Hochman, Zdeněk ; Juránek, Roman (referee) ; Španěl, Michal (advisor)
This thesis deals with moving objects detection in video sequences. The principal aim of such detection is to detect and locate motion in the image, separate individual objects, and track these objects. Subsequently, to eliminate shadows, the paper introduces method of motion detection based on Local Binary Patterns together with differential method above the HSV color space. The proposed method provides rapid and accurate movement detection in video sequences.

Tools for Automating the Workflow Processes
Vančura, Tomáš ; Macho, Tomáš (referee) ; Holek, Radovan (advisor)
The the thesis deals with tools for workflow processes automation. It describes in general what workflow is. It also briefly describes tools such as MS BizTalk Server, SAP NetWeaver, IBM WebSphere, ORACLE BPEL. The main part deals with Windows Workflow Foundation. This tool is decribed in detail together with its parts workflow runtime, workflow instances and workflow activities. One part of the thesis is a application, which uses all the possibilities of Windows Workflow Foundation.

Tracking People in Video Captured from a Drone
Lukáč, Jakub ; Orság, Filip (referee) ; Goldmann, Tomáš (advisor)
Práca rieši možnosť zaznamenávať pozíciu osôb v zázname z kamery drona a určovať ich polohu. Absolútna pozícia sledovanej osoby je odvodená vzhľadom k pozícii kamery, teda vzhľadom k umiestneniu drona vybaveného príslušnými senzormi. Zistené dáta sú po ich spracovaní vykreslené ako príslušné cesty. Práca si ďalej dáva za cieľ využiť dostupné riešenia čiastkových problémov: detekcia osôb v obraze, identifikácie jednotlivých osôb v čase, určenie vzdialenosti objektu od kamery, spracovanie potrebných senzorových dát. Následne využiť preskúmané metódy a navrhnúť riešenie, ktoré bude v reálnom čase pracovať na uvedenom probléme. Implementačná časť spočíva vo využití akcelerátoru Intel NCS v spojení s Raspberry Pi priamo ako súčasť drona. Výsledný systém je schopný generovať výstup o polohe osôb v zábere kamery a príslušne ho prezentovať.

Design of marker detection and tracking method for semi-autonomous convoy purpose
Kaura, Patrik ; Michl, Antonín (referee) ; Růžička, Michal (advisor)
This Bachelor’s thesis is focused on the description and implementation of the detection and tracking system of the passive marker for the purpose of controlling semi-autonomous platoon. The first part of the thesis summarizes certain convoy solutions, the measuring equipment used by the trucks in the convoy and it lists some of the available image processing libraries. The second part of the thesis deals with the design itself, the measurement and its results.
