Education Computer Program for Demonstration of Colors and Colors Models Principles
Vojíř, Jaromír ; Jančík, Zdeněk (referee) ; Kršek, Přemysl (advisor)
The thesis deals with development of an educational program for demonstration of principles of colors and of color models. The thesis contains theoretical study of the given question from basic terms up to use of individual color models. This is followed by a detailed analysis of the requirements necessary for development of the given educational program. In the implementation part, the process of development of the application itself is described. In the end of the thesis there is a discussion of contribution of the thesis and of possibility of future adaptations. The program can serve as a complement of study materials for students.

Hierarchical Techniques in Lighting Computation
Ligmajer, Jiří ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This master thesis deals with description of hierarchical techniques in global lighting computation. Here is explaining the importance of hierarchical techniques in lighting computation and shows method, how to use these hierarchical techniques in realtime radiosity and its extension to dynamic area lighting. These two techniques are described in detail in the first part of this project. In the other part is desing and implementation of application for dynamic area lighting computation.

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.

Realistic Rendering of a Building with Varying Lighting Conditions
Navrátil, Jan ; Seeman, Michal (referee) ; Herout, Adam (advisor)
This paper is focused on realistic rendering of interior environments with varying lighting conditions. It proposes methods of setting properties of light sources to achieve a specific scene appearence. It mainly works with light comming from a sky and sun to the scene and describes this light in relation to weather conditions, time of day and overcast factor. The goal is creating easily configurable system in which a single parameter change leads to significant change of lighting conditions. All these changes should be presented in a short video.

Study of Scattering and Polarization of Light in Biological Tissue
Abubaker, Hamed Mohamed ; Hrabovský, Miroslav (referee) ; Číp, Ondřej (referee) ; Tománek, Pavel (advisor)
Tkáňová optika nabývá rychle na významu a přesná znalost optických vlastností biologických tkání je podstatná pro výzkum v biomedicíně i pro kontrolu kvality potravin. Jestliže je vzorek tkáně osvětlen, dochází k mnohonásobnému odrazu světla. V případě postmortem neživých tkání (maso) je rozměr buněk větší než vlnová délka použitého světla. Dochází k Mieovu rozptylu prošlého nebo zpět odraženého světla, v důsledku čehož se objevují různé polarizační stavy světla. Polarizační stavy světla rozptýleného na difúzním prostředí jsou experimentálně zkoumány a modelovány. V práci jsme provedli dva modifikované experimenty: rozptyl polarizovaného světla, které dvakrát prochází vzorkem (vpřed a vzad) a jen světla, které jen prochází vzorkem. Měření rozptýleného světla ukazuje, že dochází k depolarizaci a ke stáčení polarizační roviny, což obojí závisí na orientaci svalových vláken a stárnutí tkání postmortem. Mimo experimentů byl také proveden teoretický popis difúzní biologické tkáně a byla vypočtena radiační přenosová rovnice pomocí modifikované Monte Carlo metody, která zahrnuje polarizační stav světla (PLMC). Je ukázáno, že stupeň polarizace podstatně závisí na optických vlastnostech rozptylového prostředí. Výsledky ukazují, že stav polarizace světla na výstupu závisí na stavu polarizace světla před vzorkem a na optických vlastnostech a tloušťce vrstvy prostředí v průběhu jejího stárnutí. Je také provedena korelace změn polarizace na čerstvosti masa, i popis dynamického chování polarizace při stárnutí masa.

Eye Perception of Drivers in Traffic
Vorálková, Kateřina ; Plch, Jiří (referee) ; Sedlák, Robert (advisor)
The aim of thesis is a summary and assessment of perception of drivers in traffic from the view of psychology and its influence on various aspects and the resulting effects on driving. Furthermore, it is mainly a description of the visual system and the description of light as factor of visual perception. The thesis also presents two experiments refer to the reaction time and mental reactions of driver, depending on drank out alcohol. Results of the first test of reaction time starting at the traffic lights were just a confirmation of the mentioned values from different publications and the Internet. The results of the second test, which was focused on the emotional reaction depending on the amount of ingested alcohol would be surprising to many.

Topic is processed sunset painting technique oil painting means to Latn and is crowned by a series of "Afterglow". is a continuation of previous work dealing with optical illusions and phenomena occurring in nature. "Glare, however, focuses on logical Only authorized color and shape inspired by the light background storyline. This resulted in a series of closed playing with forms and means in the final painting abstract painting

The Book in Space
Valášková, Kateřina ; Binder, Ivo (referee) ; Kocman, Jiří Hynek (advisor)
This final work is focused on the space and light and its screening by the medium of the venetian blinds which are used to separate inner and outer space. This instalation made with 5 Venetian blinds is a parallel to the book. The object is in a form of the hexagon space. It mirrors surrounding story and closes it in the pages by the mirror film. The text is called Chronicle of the melancholy and indicates the intimite of the space of book. Between lines there is a penetration of the space and light behind the pages.
