Image Processing in FPGA
Přibyl, Bronislav ; Seeman, Michal (referee) ; Zemčík, Pavel (advisor)
Images for scientific purposes are taken by optical devices, such as microscopes, cameras etc., which usually consist of system of lenses and optical sensor. Most lenses suffer from various distortions. Geometrical distortion may not be acceptable for example for precise distance measurement in the image. This thesis describes fast algorithm for separable image resampling capable of correcting smooth geometrical distortions caused by lenses. An FPGA implementation of this algorithm is also described.

Generating Procedural Textures in Shader
Veverka, Pavel ; Navrátil, Jan (referee) ; Polok, Lukáš (advisor)
This work deals with procedural texture generation using programmable graphics pipeline in OpenGL. It describes basics of OpenGL operation and programmable shading. The main contribution is the analysis of methods used for generating procedural textures using various algorithms and noise functions, with focus on Perlin noise. The examples of procedural texture shaders are demonstrated by a C++ application, displaying 3D model of Božetěchova building.

Rendering Using Deep Shadowmaps
Hypský, Jan ; Kobrtek, Jozef (referee) ; Polok, Lukáš (advisor)
In computer graphics is problematic shadow rendering. Applications require to choose the appropriate lighting and shading method with respect to speed and display quality. This work is focused on rendering the shadows and eliminate alias, arising during their creation. For to create shadows will work to implement the methods Shadow Maps and she's extensions variant Deep Shadow Maps. Shadow maps allow to create shadow independently of the scene complexity without treatment alias. Deep shadow maps are able to display shadows along with the removal of alias thereby improve the quality of shading. For lighting scene are used local Lambert lighting models. The resulting application is created with using library OpenGL.
