Interactive Animation Viewer and Editor
Ducháč, Michal ; Seeman, Michal (referee) ; Pečiva, Jan (advisor)
Since the introduction of high end graphical workstations, computer animation has quickly replaced the traditional means of animation. Nowadays computer animation has many applications e.g. video games, motion picture industry, media, weather forecasting and many others. This master thesis discusses various techniques used to created animations using computers. Keyframing, is the most common approach in computer animation. Borrowing its name from the concept of traditional hand animation, the workflow process remained the same. Basic principles of animation using key-frames are explained and an Interactive Animation Editor solution based on keyframing is proposed and the implementation of this editor is described. Editor uses the Kochanek-Bartels interpolation of values between each key-frame.

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.

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.

Water Flowing in the Landscape Visualization
Vlček, Adam ; Pečiva, Jan (referee) ; Seeman, Michal (advisor)
This work covers visualization of water flowing in the landscape with focus on displaying the results in real time. For in order to obtain data for visualization also common procedures for artificial terrain and natural looking textures are introduced, as well as simple water flow simulation algorithms. The final objective of this work is to present an interactive environment, which will offer interesting visual output in direct response to the user.

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.

Semi-Automatic Control of RC Models
Filo, Martin ; Seeman, Michal (referee) ; Zemčík, Pavel (advisor)
The Bachelor thesis describes problems connected with automatization of RC airplane models. It solves problem with stabilization during the flight from any space orientation. It attaches a set of functions to control the model behavior. There is also a brief description of easy "Do it yourself" gyrocopic unit aimed to testing the behavior of the model on the ground. The thesis uses provided set of functions for very basic control of board with microcontroller MSP430F169.

"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.

Motion-Blurred Image Restoration
Rajnoch, Zdeněk ; Seeman, Michal (referee) ; Bařina, David (advisor)
Goal of this thesis is restauration of motion blurred images. Motion blurr is assumed to be only over a narrow line rotated by any angle to x axis. There are several methods which are theoretically explained and compared on synthetically blurred images in several different conditions. After that motion blurred images are restaurated with some of deconvolution methods.

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.
