Optimalization for Stereoscopic Visualization
Zelníček, Leoš ; Seeman, Michal (referee) ; Beran, Vítězslav (advisor)
This work envolves basic options of human visual sense, describes matter of depth perception. We analyze binocular vision of humans, its limits, which must be considered, and followed when trying to project stereoscopic pictures. Then, we mention the most common methods of stereoscopic projection, reader is made acquainted with their options, advantages, and difficulties. The biggest part of this work is dedicated to the optimalizations themselves. They are focused on the most effective rendering of 3D scenes using stereoscopic technology. The effort is to make the best stereoscopic engine as possible and to inspect and improve displayed scene, so that the stereoeffect would be the best. Trivisio ARvision-3D HMD was used for testing purposes.

Simulation of Lens Features
Kučiš, Michal ; Seeman, Michal (referee) ; Zemčík, Pavel (advisor)
Computer vision algorithms typically process real world image data acquired by cameras or video cameras. Such image data suffer from imperfections cause by the acquisition process. This paper focuses on simulation of the acquisition process on simulation of the acquisition process in order to enable rendering of images based on a 3D generated model. Imperfections, such as geometry distorion, chromatic aberration, depth of field effect, motion blur, vignetting and lens flare are considered.

"Fisheye" Camera Projection
Macík, Pavel ; Juránek, Roman (referee) ; Seeman, Michal (advisor)
The thesis describes theoretical fundamentals of optics and problems of ray-tracing method, ray-triangle intersection computation included. Next section describes concept of three different camera models for ray-tracing method - plain camera, pinehole camea and spherical camera (fish-eye). The thesis comparse properties and capabilities of camera models and their effect to projected image of a scene. The program for raytracing was implemented for purposes of the thesis including implementation of camera models described in the thesis.

Realistic Rendering of a Building with Varying Lighting Conditions
Navrátil, Jan ; Seeman, Michal (referee) ; Herout, Adam (advisor)
This paper is focused on realistic rendering of interior environments with varying lighting conditions. It proposes methods of setting properties of light sources to achieve a specific scene appearence. It mainly works with light comming from a sky and sun to the scene and describes this light in relation to weather conditions, time of day and overcast factor. The goal is creating easily configurable system in which a single parameter change leads to significant change of lighting conditions. All these changes should be presented in a short video.

Application for Practicing Rapid Reading Techniques
Sokol, Miroslav ; Seeman, Michal (referee) ; Herout, Adam (advisor)
Main goal of this bachelor´s thesis is creation user interface for correct fast reading practise. Four moduls train various abilities of human eyes in regard to average and advanced reader. Application was created as WinForm and thematically is connected with human sight, which hide incredible potential for most of people. The bachelor´s thesis analyse features of eye, individual types of exercises, implementation, concrete developement of user interface and users reactions from their own testing.

3D Photo Slideshow Using OpenGL
Ondrejíček, Marián ; Navrátil, Jan (referee) ; Seeman, Michal (advisor)
The aim of this thesis was to design a photo slideshow in 3D space using OpenGL and to implement functional application. Also there is description of Qt toolkit, which was used to design graphical user interface of the program. Furthermore there are explained basics of quaternion interpolation, which is the core of animation and camera system. The second part describes practical realization and each part of the project in details. Application was successfully implemented. In the end, the results are discussed, including possibilities of future development.

Lens Distortion Correction
Doležel, Michal ; Seeman, Michal (referee) ; Šiler, Ondřej (advisor)
The bachelor thesis deals with methods of removing digital photographies aberrations caused by photographical lens distortions. It describes the most frequent lens aberrations, deals with their causes, followed by consequences of these aberrations on destination pictures and ways of their removing from digital photographies. The main goal of the thesis is to design and implement tools for removing lens distortions aberrations from a digital photography. The application was created in C++ programming language with the support of Cimg and Imagemagick libraries. The application was also developed and tested for MS Windows XP and Linux Kubuntu 7.10 operation systems. The results are compared with professional tools for digital photography processing.

Algorithm Acceleration on Larrabee Platform
Veselý, Ivo ; Seeman, Michal (referee) ; Zemčík, Pavel (advisor)
Intel Larrabee is one of the first of fully programmable graphical architectures. Thesis describes this many-core architecture by hardware implementation and programmer's model point of view. Larrabee bets on many complete in-order cores, built over x86 instruction set. Cores contains four hardware threads, each with it's own register file, and new vector processing unit. Vector processing unit together with instruction set extension rapidly increases system performance. New cache modes helps to increase throughput even when irregular data structures. This architecture is not focused only on computer graphics nor image processing, but all parallel tasks. Second part of this text deals with hologram synthesis. Specifically, it brings two new methods for patch of point light sources generation with concrete radiation.

Presentation Software for Physics on Elementary Schools
Matoušek, Miroslav ; Seeman, Michal (referee) ; Štancl, Vít (advisor)
This final thesis deals with the software supporting the education through the presenting the physical process. Specifically, it deals with the kinematics on the level of the basic school and secondary school. Next there are described the basics of pedagogy, didactics, simulation and modelling referring to the suggested programme. There is also a suggested system and its graphic user interface based on the gained findings which is later implemented.
