Synthetic Data Set Generator for Traffic Analysis
Šlosár, Peter ; Juránková, Markéta (referee) ; Herout, Adam (advisor)
This Master's thesis deals with the design and development of tools for generating a synthetic dataset for traffic analysis purposes. The first part contains a brief introduction to the vehicle detection and rendering methods. Blender and the set of scripts are used to create highly customizable training images dataset and synthetic videos from a single photograph. Great care is taken to create very realistic output, that is suitable for further processing in field of traffic analysis. Produced images and videos are automatically richly annotated. Achieved results are tested by training a sample car detector and evaluated with real life testing data. Synthetic dataset outperforms real training datasets in this comparison of the detection rate. Computational demands of the tools are evaluated as well. The final part sums up the contribution of this thesis and outlines some extensions of the tools for the future.

Changing Object Appearance by Adding Fur
Pražák, Martin ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
Cílem této práce je demonstrovat možnost renderování srsti přímo do existujících obrazů bez toho, aby bylo po uživateli požadováno překreslení všech pixelů nebo dodání kompletní 3D geometrie a osvětlení. Srst je přidána na povrch objektů pomocí extrakce jejich přibližného tvaru a světelných informací z obrazu a takto získaný objekt je poté přerenderován. Tento přístup je nový v tom, že vysokoúrovňové úpravy obrazu (jako např. přidání srsti), mohou úspěšně vést k vizuálně korektním výsledkům a to i přes omezení nepřesnou geometrií a světelnými podmínkami. Relativně velká množina technik použitých v této práci zahrnuje obrazy s velkým dynamickým rozsahem, metody extrakce 3D tvaru z obrazu, výsledky výzkumu vnímání tvaru a osvětlení a fotorealistické renderování. Hlavním cílem práce je potvrdit koncept popsaný výše. Hlavním implementačním jazykem bylo C++ s použitím knihoven wxWidgets, OpenGL a libTIFF. Renderování bylo realizováno v software 3Delight kompatibilním se standardem Renderman, za pomoci množiny shaderů implementovaných v nativním jazyce Rendermanu.

Photorealistic Rendering Using "Photon Mapping" Method
Lysek, Tomáš ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
This master thesis focuses on photon mapping rendering technique. A simple photon mapping was implemented as a baseline and then progressive photon mapping was prepared for CPU and GPU. After implementing progressive photon mapping on GPU, further acceleration techniques were proposed. Finally, in the thesis, genetic clustering algorithm for suitable clusters on GPU was proposed.

Multispectral Map Building in Mobile Robotics
Burian, František ; Mazal,, Jan (referee) ; Zemčík, Pavel (referee) ; Žalud, Luděk (advisor)
The dissertation deals with utilisation of multispectral optical measurement for data fusion that may be used for visual telepresence and indoor/outdoor mapping by heterogeneous mobile robotic system. Optical proximity sensors, thermal imagers, and tricolour cameras are used for the fusion. The described algorithms are optimised to work in real-time and implemented on CASSANDRA robotic system made by our robotic research group.

Visualisation of hydraulic structures
Urbanec, Luděk ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The aim is to implement the process for creating realistic visuals (including animations) for a small hydroelectric power plant Litomerice. This thesis is the creation of spatial models based on existing drawings. Using these models will be developed with an emphasis on rendering realistic scenes created. An important part of the work output will also be focused primarily on the animation feature demonstrations of technological equipment, handling and maintenance work on the water. A key outcome will be the documentation process of spatial models, realistic rendering and animation.

3D modelling in Blender
Matiášek, Tomáš ; Šedivá, Zuzana (advisor) ; Pour, Jan (referee)
The goal of this work is to create a comprehensive manual for program Blender. The work will guide a beginner user through the process of modelling. Blender is a free software used for creating animations and 3D visualizations which can then be used in the television industry, game industry, movies or commercials. This work in it's introduction mentions benefits and disadvantages of this product and lists similar products available worldwide. The rest of the work is dedicated to creating 3D models and describes scene modelling, texturing, lighting and rendering practices.
