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.

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.

Techniques Used for Image Blurring and Sharpening
Lichý, Stanislav ; Juránek, Roman (referee) ; Venera, Jiří (advisor)
This bachelor's thesis deals with methods of digital image filtering. First of all, it contains basic notions necessary to understand problems, such as digital image, pixel, color spaces, noise and noise types. Secondly, important algorithms of image sharpening and noise reduction are described. Then, algorithms working principles are explained. Achieved results are analyzed together with a discussion about algorithms suitability and their time complexity. Lastly, selected algorithms are implemented by C++ programming language, using an open source library OpenCV.

Vertex/Pixel Shaders in Realtime Rendering
Ligmajer, Jiří ; Havel, Jiří (referee) ; Švub, Miroslav (advisor)
My bachelor's thesis is about vertex and pixel shaders. It is engaged in evolution, funcionality and usage of shaders in realtime graphics. This bachelor's thesis also includes tutorials, that are describing theory and implementation of three realtime rendering techniques, which were chosen by me. Results of my realtime techniques are evaluated at the end of my book.

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.

Image Interpolation
Václavík, Jan ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This bachelor’s thesis deals with the comparison of different interpolation methods. And their use on different grey scaled 2D images. The main part is dealing with linear, quadratic and cubic method and their qualitative evaluation for multiple resizing of image resolution. The analysis is resolved in computing system Matlab.

Implementation of edge detector using wavelet transform
Pálka, Zbyněk ; Rášo, Ondřej (referee) ; Růčka, Lukáš (advisor)
This thesis is focused on edge detection in image. In theoretical part are contained genarally used methods of edge detection using first and second-order derivate and both of mentioned methods are described here. Further it’s deiscribed here continuous, descrete and two dimensional descrete wavelet transform and process of noise removing in image by descrete wavelet transform. In next part are analysed two methods of edge detection using wavelet transform and their possible realizations in program Matlab. In practical part of thesis is in detail described algorithm of program on edge detection using wavelet transform and it‘s described here individual functions of program. The main content of practical part are visual results of wavelet edge detector and their comparison with Canny, Prewitt and Sobel edge detector.

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.
