Techniques Used for Image Smoothing, Blurring and Sharpening
Kubínek, Jiří ; Šilhavá, Jana (referee) ; Venera, Jiří (advisor)
This work is dedicated to methods used for digital image editing. It defines fundamental terms for this work as color space or noise. Above all, it analyses methods allowing image sharpening and blurring. It describes some of the most known algorithms from the theoretical point of view, but also introduces their implementation in C programming language. There are compared according to time complexity. The purpose of this work is to introduce digital image filtering and demonstrate elementary procedures used for their implementation.

Raster to Vector Conversion
Siblík, Jan ; Venera, Jiří (referee) ; Šilhavá, Jana (advisor)
This bachelors thesis inspects an issue of converting a raster image into vector representation. It describes theoretical basis for image preprocessing techniques, theory and means of edge detection and some possible techniques of image vectorization. It also desribes designing and realization of a demostrative aplicetion, which is the programming part of this thesis.

Image Transformations
Novák, Radim ; Juránek, Roman (referee) ; Venera, Jiří (advisor)
The main goal of this thesis is to introduce two fundamental geometric transformations in 2D space - by changing the resolution together with related image resampling and image rotation. Also brightness interpolation, technique of mapping and other problems related to the topic are explained there, i.e. Fourier transformations, problem with aliasing and technique of aliasing suppression.

Light Maps in 3D Computer Graphics
Vrána, Jaroslav ; Přibyl, Jaroslav (referee) ; Venera, Jiří (advisor)
Bachelor´s thesis describes techniques that are used in virtual terrain creation. First part describes generating of the height maps and the textures, after that is shown the terrain rendering and texturing. And next that is described the light maps generating. I show tree algorithms for the light maps generating, two for the terrain a one for the water. At the end I describe extension for the acceleration of the scene.

Fractals in Computer Graphics
Šelepa, Jan ; Venera, Jiří (referee) ; Sumec, Stanislav (advisor)
The goal of this work is to give introduction and specification of fractals. The first chapter presents the basics of fractal geometry. The second chapter maps the history of fractals and points out the most important people of fractal science. The third chapter presents fractal classification based on several criteria and gives basic examples. The fourth chapter is a summary of widely used applications for fractal creation. The last chapter describes the application that was made to demonstrate given algorithms and fractals mentioned in this thesis.

Image Morphing and Warping
Kuběna, Petr ; Šilhavá, Jana (referee) ; Venera, Jiří (advisor)
Warping and morphing are computer effects that are mainly used in show-bussines. Thessis contains procedures and techniques that are necessary for their creation. It is aimed at work with discrete two-dimensional image. Integral part is the demo program, which allow users to create such effects.

Canny's Operator and Other Useful Edge Detectors
Janda, Miloš ; Juránek, Roman (referee) ; Venera, Jiří (advisor)
This work introduces main approaches for digital image processing and defines fundamental terms for successful understanding. Main aim is description of several suitable methods used in digital image pre-processing, methods for edge detection and consequent post-processing of these. The final goal of this work is effective implementation and complex comparison of methods for edge detection.
