Scene Analysis Based on the 2D Images
Hejtmánek, Martin ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
This thesis deals with an object surface analysis in a simple scene represented by two-dimensional raster image. It summarizes the most common methods used within this branch of information technology and explains both their advantages and drawbacks. It introduces the design of an surface profile analysis algorithm based on the lighting analysis using knowledge and experiences from previous work. It contains a detailed description of the implemented algorithm and discusses the experimental results. It also brings up options for the possible enhancement of the projected algorithm.

IR camera data processing
Malík, Dalibor ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
The aim of this master’s thesis is to give information about the thermo camera measurement with error minimization. The basic concepts of thermography are explained with an implementation of postprocesing technique which uses graphically modified thermogram back projected to the scene. This is closely related to the scene design, calibration of thermal camera with projector, image rectification, thermogram processing with highlighting of interesting information and implementation of control elements as the user interface. The results obtained are analyzed and re-evaluated.

Firearm Type Identification in an Image
Čech, Ondřej ; Drahanský, Martin (referee) ; Dvořák, Michal (advisor)
Main goal of this work is to design, implement and test an approach for classifying firearms in an image into categories with short and long fireams, and then with single shot, multi-barreled, repeating and semi-automatic/automatic firearms. This problem was solved using SVM classifier together with Harris corner detector, FREAK descriptor and Bag of Words method. Accuracy of final program is up to 13,3 %.

Performance Evaluation of Graphics Accelerator
Vanek, Juraj ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
This paper deals with possibilities and functions of modern graphic accelerators and with measuring performance under OpenGL interface. Widespread algorithms to render scene in real-time are used. It focuses on how to test every part of accelerator's graphic pipeline as well as measure performance in rendering of advanced effects and theoretical speed at general purpose calculations through graphic processor. This testing is realized by implementing multiple test series and their further evaluation. Final application enables setting of test parameters and outputs a score, by which is possible to judge accelerator's performance in comparison among themselves.

Culture and public centre Brno-damlake/Theme"Brno-city in the midle of the Europe"/
Mikulka, Petr ; Žalmanová,, Petra (referee) ; Šindlar, Jiljí (advisor)
The theme of Master Thesis is the Brno dam and its effective utilization. The very subject of this thesis is the Cultural and Social Center (the Center). The project follows a broad urban context and provides a new insight into the operation and use of this site. It contains a proposal of movement coordination and effective utilization of the most attractive areas closely related to the water surface. Cultural and Social Center is designed as a part of the landscape. It connects two levels of trails leading around the object. This connection is expressed through the dominant stairs. The program of the Center complements and evaluates leisure activities of the site, plus the Center offers an extraordinary space. Digital RGB spectrum system senses the current weather and converts the results into a graphic and scenic projection. Thanks to this system a new concept of space is continuously formed. The atmosphere, temperature, texture, intensity etc.. The visitor thus will never be a part of the same "exhibition." The first floor, (level +0,00m) around the water surface, is preferably used as a Cultural and Social Center. It has three naves of the Center, foyer with cafe and snacks, as well as it covers a DPMB building of cabeling. Few parts of the facade are designed as a sliding facade, thus visitors could stay in direct contact with the water surface and landscape. Second floor – (level +3,50m) is an spatial continuation on the Center and the rest is mostly used for technical security of the building. In foyer there is a second part of cafe – more private and relaxing room. Third floor (level +7,00m) is connected with the trail going around the building. At this level takes place leisure and educational center, which is complemented by the multifunction hall and an administrative facilities. The idea of landscape use is to provide an outdoor sports urban park a la Miralles urban parks.

Slovene National Theatre in Ljubljana
Pivoňková, Dagmara ; Bajger, Oldřich (referee) ; Kynčl, Jakub (advisor)
The plot for a new theater is in historic centre of Ljubljana and it is defined by block of existing buildings. I designed theatre with 3 variable scenes – one for 500 spectators, two for 100 people each. In addition i propose the theatre square – big exterior arena. The proposed building is an ending of urbanictic axe, that is why it has shape of monumental gate. The gate is oriented to the south, so i covered the fasade with huge fotovoltaic sreen, that is collecting electric energy during the day and shining this energy out during the night as a big city culture screen..

Special Effects in Cinematography
Frkáň, Lukáš ; Rujbrová, Šárka (referee) ; Ellederová, Eva (advisor)
Cílem této bakalářské práce je vymezit pojem speciální efekty v kinematografii, poskytnout základní informace o speciálních efektech v teoretické a praktické rovině, rozdělit speciální efekty do kategorií a podkategorií včetně podrobného popisu speciálních efektů uvedených v práci a historického pozadí. Práce se také zabývá návrhem speciálních efektů a jejich omezeními, aplikacemi ve filmovém průmyslu a případně v dalších průmyslových odvětvích. V první fázi je stručně zmíněna historie kinematografie. Tato studie se dále zaměřuje na popis vizuálních efektů používaných v raných stádiích kinematografie, zatímco na závěr se věnuje moderním efektům, které se v současnosti používají. Následně zkoumá popis praktických efektů, čímž uzavírá teoretickou část. V poslední části se znalosti konceptu speciálních efektů získaných v teoretické části promítají a aplikují při analýze filmů, kterým byla udělena Cena Akademie v kategorií nejlepší vizuální efekty.

Rendering Complex 3D Scenes
Mrkvička, Tomáš ; Kršek, Přemysl (referee) ; Herout, Adam (advisor)
This thesis deals with representation of large and complex 3D scenes which are usually used by modern computer games. Main aim is design and implementation of data driven rendering system. Proper rendering is directed (driven) by scene description. This description is also designed with respect to scene creators whose typically do not have deep knowledge of programming languages in contrast to game programming developers. First part is focused on design of efficient scene description and its possible applications at scene rendering. Second part is focused on proper system implementation. Finally, consequently important system optimizations are mentioned too.

Large Scene Rendering
Langer, Lukáš ; Tóth, Michal (referee) ; Starka, Tomáš (advisor)
Work discusses rendering of complex scenes and terrain. It's main task is to show the extensive scenery terrain that normally do not fit in the graphic card memory. It introduce the theory of terrain rendering including terrain level of detail algoritms. The paper presents the design and implementation of application that implements dynamic streaming of complex terrain.
