Analysis of General Polygon Boolean Operation Algorithms
Daněk, Tomáš ; Zemčík, Pavel (referee) ; Beran, Vítězslav (advisor)
This thesis deals with general polygon boolean operation algorithms. Boolean operations are e.g. intersection, union or difference. A general polygon can be e.g. a selfinterecting polygon with inner hole. Clipping of polygons against a rectangular window is probably the most familiar boolean operation on polygons. At first, basic definitions are listed. Then the principles of a selected set of boolean operation algorithms are reviewed. Finally, a complex comparison of the algorithms is undertaken. Performance as well as the ability to handle degenerate cases are tested. The output of this thesis is an overall evaluation of algorithm properties and a dynamic library that contains the implementation of all of the tested algorithms.

Visualization and Modelling of Molecules and Crystalles
Bubník, Václav ; Chudý, Robert (referee) ; Zemčík, Pavel (advisor)
Aplikace pro vizualizaci a modelování molekul nejsou dosud příliš poznamenány současným hardware vyvinutým pro potřeby počítačových her. Cílem projektu je navrhnout intuitivní rozhraní s novými widgety specializovanými na atomové struktury a vizualizací využívající moderní hardware grafických karet. Důležitou částí je také dosažení vysoké přesnosti modelování, obvykle dostupné pouze u profesionálních CAD programů.

Online Business Cards Generator
Turic, Matúš ; Zemčík, Pavel (referee) ; Beran, Vítězslav (advisor)
Vizitky jsou stále nedílnou součástí marketingu. Vizitka představuje snadný způsob výměny základních kontaktních informací mezi jednotlivci. Tato bakalářská práce se zabýva popisem a tvorbou webové aplikace, pomocí níž si bude každý moci vytvořit vlastní vizitku podle předem připravených šablon. Výsledkem webové aplikace je PDF soubor s vytvořenými vizitkami.

Radar Altimeter for Ultralight Aircraft
Absolon, Marek ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
The main topic of this paper is a radar ranging for use in an aircraft altitude measurement. This should help beginner pilots in practicing landing and take off. To achieve this aim, we chose to use continuous-wave radars with frequency modulation (FMCW). Our solution is based on linear frequency modulation method using triangular modulation pattern. During the testing, it was found out, that radars with 24 GHz bandwidth have a range resolution from 1 meter (depending on modulation depth) to 13 metres. This range is sufficient for usage in training of takeoffs and landings, which is the real purpose of this paper. Another good finding is, that during takeoff and landing, there is minimal occurrence of doppler frequencies. Final algorithm works on principle of two currently processed spectrums, which are substracted. Afterwards, found peaks are validated on current spectrum.

Parametric Geometry Sketch Tool
Čižmarik, Roman ; Klepárník, Petr (referee) ; Zemčík, Pavel (advisor)
The aim of this work is to design and implement parametric geometry sketchtool. The solution to this problem consists of two parts, to create a library of base dynamic geometry functions and GUI. Functionality of the created library will be demonstrated by two user interfaces, each using the library in different way. Using the resulting library and toolkit Qt allows to quickly and easily create new geometric sketchtools.

Strategy for Game Systems
Švestka, Marek ; Tóth, Michal (referee) ; Zemčík, Pavel (advisor)
This thesis resolves the artificial intelligence representation in computer games. The goal was to find it's suitable interpretation methods. The issue was solved with "map"implementation, which is the n-dimension matrix holding the information about current game state for the concrete player. There were various types of these matrixes used in this thesis. Furthermore was designed a way to evolve computer opponents during the gameplay and created an algorithm, that gives the idea of the space in which it is located. Benefit from this thesis is a solution that makes artificial adversary close to human gameplay behavior. The outcome could also be used in simulators for military battles in real world.

Evaluation of Object Detection in Image
Černošek, Bedřich ; Behúň, Kamil (referee) ; Zemčík, Pavel (advisor)
The main goal of this bachelor's thesis was to propose the evaluation method of object detection. Result of this work was to create a program which performs the evaluation of object detection on suitable data sample and intuitively displays result to user. The task was to propose suitable experiments and dataset for proving correctness of evaluation. Part of this work was to find optimal parameters for face detection and optimal photo preprocessing before the face detection.

System for Import of Photos
Pučálka, Martin ; Mlích, Jozef (referee) ; Zemčík, Pavel (advisor)
The goal of this thesis is design and implementation of stand-alone program for import of photos. Program can find already imported photos in computer and skip them during next import. Searching for identic photos is based on comparing metadata. Thanks to this way of comparasion, aplication doesn't need to load and compare image data and searching can be faster. Implemented were also functions for separating, renaming and adding metatada to photos.

Object Detection and Recognition in Image
Muzikářová, Michaela ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
This bachelor's thesis deals with design and implementation of client-server application for object recognition with the use of existing mobile application. Theoretical part describes the differences between human and computer vision, followed by information about object detection and recognition with selected methods. The next section provides a detailed overview of artificial neural networks, which were used for this work, with their qualities for object recognition. Following part examines selected mobile applications for object recognition, followed by existing frameworks and libraries with focus on artificial neural networks. Among these, Caffe Framework was selected for the work. The next section illustrates the progress of design and implementation and describes the system, along with experiments and dataset used to prove its functionality.
