Potential usage of geothermal energy in the Czech Republic
Bombík, Zdeněk ; Mastný, Petr (referee) ; Radil, Lukáš (advisor)
This bachelor thesis is dealing with geothermal energy problems and its potential of possible utilization in the Czech Republic. In this work, the description of technologies for utilizing geothermal energy of higher, middle and lower temperatures, is presented. The thesis also includes the description of methods for direct and cogenerative development of electrical power. At the end of this thesis, the first realized project of geothermal equipment in the Czech Republic, situated in Litoměřice, is clarified. The work is also concerned about the analysis of its area and geothermal energy utilizing potential

Merging of Different Exposured Photographs, HDR
Šmida, Vladimír ; Juránek, Roman (referee) ; Seeman, Michal (advisor)
High Dynamic Range Imaging (HDRI) is an emerging field in image postprocessing with non-trivial relations to many different areas, such as image synthesis, computer vision, video and image processing, digital photography, special effects among others. This bachelor's thesis deals with the usage of HDRI in digital photography. Conventional digital cameras are not able to record the full tonal range of the scene. Therefore, if we want to capture a high dynamic range scene, by setting the exposure time we have to choose only a small range of tones which will be well depicted. The rest of the photograph will loose important detail. The method presented and implemented in the scope of this thesis enables us to create HDR picture with realistic values of tones out of several differently exposured photographs.

HDR Images Processing
Musil, Martin ; Pečiva, Jan (referee) ; Zemčík, Pavel (advisor)
HDR images have much wider range of luminance values, than photographs created and displayed in a standard 24-bit format. There are several ways to create images with high dynamic range, but this diploma thesis focuses just on one of them, and it is the method of composing out of series of standard photographs. The goal of the first part of the text consists of studying, understanding and eventually writing down the basic terms and knowledge in the subject of image composition and other processes, necessary to create HDR photographs. Next the procedure of creating images with high dynamic range, processing and converting them into viewable form, is described. The following chapter contains the design of the application, which creates this kind of photographs, and which is smoothly changing into its actual implementation afterwards. The process of experimenting and its results are presented and discussed firstly in their own chapter and secondly in the attachment. The conclusion contains the summary of the work and the options of possible expansion.

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.

The use of high-resolution photographs in the real estate practice.
Janů, Ondřej ; Daňhel, Petr (referee) ; Klika, Pavel (advisor)
The aim of the work was to put together the list of possible ways to use high resolution image in real estate practice. Photographies are created by stitching more than one image on itself. Further on was developed methodology of working with these images and was made an illustration with detailed description of the procedure for each individual case. For each procedure were proposed possibilities in practical using. For the thesis purposes was conducted real estate and public survey. Based on results of the survey were purposed draft measures to improve internet real estate advertising.

HDR image processing tool
Kocich, Petr ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
First part describe terms HDR, image processing and some basic terms of photography. There is describe requirements for corect capture high dynamic range scene through the use of colection of photos with same scene but with diferent exposure value. Next thing is describnig principles for connect these photos to one photo with high dynamic range. Tone mapping methods describes compression of high dynamic range to dynamic range of standard screens. Some commercial program for HDR making is describe here. Main algoritmus show possibility how display high dynamic range scene through the use of kernel of usefull areas.

Simulation of LED retrofits under operational conditions
Tomeš, Martin ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
This Master’s Thesis on Simulation of LED retrofits under operational conditions is divided into theoretical and practical part. Theoretical part in the introductory section deals with the concepts of lighting technology and presents some electric light sources, such as classic bulbs, halogen bulbs, linear and compact fluorescent lamps. It also describes the principle of electroluminescent light sources (LED), which discusses principles of yielding a white light, the main advantages of LED etc. The reader is familiar with the issue of compensation the linear fluorescent lamps tubular LED source and with the work environment programme ReluxPro that is used for design of the lighting system. Practical part of the thesis is divided into two chapters. In the first chapter, measured linear fluorescent lamps and LED modules for the light-technical parameters, luminous intensity, radiation spectrum and settling time of light sources are evaluated and compared. The second chapter is solved by using ReluxPro, which explores the impact on the lighting and the brightness of the room layout SA 5.10 while using various light sources. In conclusion, there is an economic aspect of linear fluorescent lamps and LED modules analyzed. Results from the program ReluxPro are continuously compared with real measured values.
