Methods of object skeletonization in biomedical images
Matejčík, Martin ; Odstrčilík, Jan (referee) ; Jakubíček, Roman (advisor)
This thesis deals with the skeletonization of binary objects in 2D images. It describes the principles, approaches and uses of skeletonization. The functioning of the Lee, Zhang, Guo-Hall, and Medial Axis Transform methods is also theoretically explained. A custom image dataset consisting of biomedical and non-biomedical images of different topological levels was created. The image dataset was subjected to skeletonization by all of the selected methods. Experiments were designed to investigate the behavior of skeletonization under the influence of boundary noise and rotation. New modified images from the original dataset were created for individual experiments. The results indicated a degraded quality of skeletons from images affected by medium and high boundary noise. The methods showed robustness to rotation only at rotation angles of 90, 180 and 270 degrees, with the best results produced by Medial axis transform method. The calculation time of individual methods was also monitored depending on the increasing number of pixels in the image. The Guo-Hall method produced interesting results, but was also the slowest.

Spica/ Brno, Nove sady 49°11'20.3"N 16°36'29.4"E
Csanda, Denis ; Kisová, Barbora (referee) ; Nový, Vítězslav (advisor)
Design „micro-urbanism“ in designated area. Aim of this work is to find suitable development strategy of open city block. Bachelor‘s thesis adresses design of poly-functional building, including town hall and housing in city Brno. The main theme is to find maximal, yet optimal solution to site, which functions as parking space. The design tries to complete corner of designated city block, which will be part of future „south“ neighbourhood. The townhall and housing should function in harmony, which means the building will „live“ all-day long. The site is located in the node of historic centre and new planned neighbourhood. Between the site and neighbouring building will be parking garage tucked under the ground. Also there will be multifunction hall undergound center of the site. Design of the volume is complex and consists of pedestal and 3 towers. These towers volumes pixelate into the pedestal and open into the courtyard. Facade consists od unite form, which disolves and open in the upper levels.

Vertex and Pixel Shaders for 3D Visualization of grass
Dokoupil, Martin ; Chudý, Peter (referee) ; Kršek, Přemysl (advisor)
This thesis describes the way to create three-dimensional visualization of grass in computer graphic. Contains progress of grass visualization from past to present. Contains shader intro and its use for visualization. Text mention scene graph which has been used for implementation. Text describes three levels of detail and implemetation of waving grass. Text compares frame speed for each level of grass and frame speed for complete visualized grass.

The Students themselves - Student Center Poříčí
Turčan, Andrej ; Poslušná, Iva (referee) ; Jura, Pavel (advisor)
In my bachelor thesis I design the new student center situated on the bank of the river Svratka in the city of Brno. Main concept is based on mutual communication and common activities of the students. The body of project becomes diagonal stair hall, which connects all social areas and creates different platforms for various student activities.

Texture Characteristics
Zahradnik, Roman ; Šiler, Ondřej (referee) ; Švub, Miroslav (advisor)
Aim of this project is to evaluate effectivity of various texture features within the context of image processing, particulary the task of texture recognition and classification. My work focuses on comparing and discussion of usage and efficiency of texture features based on local binary patterns and co- ccurence matrices. As classification algorithm is concerned, cluster analysis was choosen.

Software for Microscope Image Processing and Analysis
Pavlišta, Libor ; Odstrčilík, Jan (referee) ; Čmiel, Vratislav (advisor)
This project informs about the basic image processing on grayscale and binary images. The project deals with analyzing the data obtained. Acquaints with terms such as morphology and image segmentation. Acquired knowledge is applied to create a program to complete the processing of microscopic images in LabView programming environment with subsequent analysis and plotting of results into image. For a better idea supporting data about operation in progress are continuous images.

Performance Evaluation of Graphics Accelerator
Dvořák, Milan ; Šolony, Marek (referee) ; Jošth, Radovan (advisor)
This bachelor thesis deals with a performance evaluation of graphics accelerators. Properties of the current graphics accelerators and existing solutions for evaluating their performance are summarized. An own methodology for performance evaluation is proposed and the implementation of an OpenGL aplication with GLUT and GLEW libraries is described. In the last part, several graphic cards are tested, the influence of various factors is examined, and the measured results are discussed.

Multimedia Browser for Lectures
Kubalík, Jakub ; Potúček, Igor (referee) ; Schwarz, Petr (advisor)
In preamble reader will understand the purpose of this project and why it was initiated. It's large team project, so description of its structure represents main part of this report. A core of the browser contain a lot of techniques, e.g. system of components, special internal communication and other. The main goals of this system are portability and reusability - there is exact specification of syntax rules and used data formats. Non-interchangeable role in project has format XML. Invention of new components was the last intervention in project, with intention to use of the project in future and involve in complex search engine - the engine discuss final part of report.
