Visualization of Route Information and Elevation Profile
Kolčárek, Michal ; Přibyl, Bronislav (referee) ; Kubíček, Radek (advisor)
An ambition of this thesis was to create a complex program for managing geographic data from GPS receiver with graphic user interface. The final application is able to show an information about tracks, to draw tracks into map and to create graphs. Main challenge was to create a user friendly aplication, which is easy to manage even by beginner users. In this application was used a Java language using objected-oriented paradigm.

Content Based Photo Search
Bařinka, Radek ; Přibyl, Bronislav (referee) ; Španěl, Michal (advisor)
This thesis deals with the problematics of searching of photographs by the content and existing applications dealing with this subject. The aim is the local working application for searching of photographs by the content given by a pattern. The solution consists of the simple graphical interface, the support of saving data and the reading of data from the transferable local database. The application searches the photographs of a given set that are similar to the given pattern. The results are visually depicted to the user. Feature extraction and detection by photo content is solved by means SURF algorithm, visual vocabulary created by method k-means and a description of photography as a bag of words. In addition,the searching of photographs by cosine similarity of vectors enriched with the independent calculation of homography and the selection of regions searched in an example photography. At the end of the technical report the results of testing are presented.

Real-Time Displaying Quality Maps of Silicon Wafers
Mareček, Matěj ; Přibyl, Bronislav (referee) ; Herout, Adam (advisor)
The goal of this bachelor's thesis is to design and implement a software system that can collect real-time data from measurements of silicon wafers. There could be tens or hundreds data sources of measurements and data from these measurements can be rendered (also in real time). This work contains a description of the process of manufacturing and testing of integrated circuits. Subsequently, there is description of system architecture design, interior architecture of real-time server and GUI of client application. In the last section, there is shown how rendering of silicon wafers was implemented on platform JavaFX 2.2 and also implementation of hybrid multi-threading server architecture.

Social Network from Photo Gallery
Polesný, Ondřej ; Přibyl, Bronislav (referee) ; Mlích, Jozef (advisor)
This thesis deals with recognition of persons and their relationships from static images and presents ways in which these information can be used. That includes methods for detection and recognition of faces, presentation of photos in web-based gallery and methods for recognition of relationships between photographed persons. Part of this thesis is evaluation of the results, both in terms of program success in automated operations by establishing a set of test data with known relationships between people, and in terms of efficiency and functionality of the system for end users.

Microcomputer in Ultramicro Aircraft/Helicopter
Široký, Adam ; Přibyl, Bronislav (referee) ; Zemčík, Pavel (advisor)
This thesis deals with the development of embedded system for ultra light airplanes and helicopters. The aim is to suggest, make and test the system with help of which it would be possible to take notes of a flight data set. The set is formed by GPS coordinates, altitude, speed and leans in both axes. The base of the system is created on microcontroller of the MSP430 family by Texas Instruments. A reader will be offered the used hardware, the system suggestion, its realization, the way of function verification and the possibility of using of the suggested system.

Camera Pose Estimation from Lines using Direct Linear Transformation
Přibyl, Bronislav ; Pajdla, Tomáš (referee) ; Koch, Reinhard (referee) ; Zemčík, Pavel (advisor)
Tato disertační práce se zabývá odhadem pózy kamery z korespondencí 3D a 2D přímek, tedy tzv. perspektivním problémem n přímek (angl. Perspective- n -Line, PnL). Pozornost je soustředěna na případy s velkým počtem čar, které mohou být efektivně řešeny metodami využívajícími lineární formulaci PnL. Dosud byly známy pouze metody pracující s korespondencemi 3D bodů a 2D přímek. Na základě tohoto pozorování byly navrženy dvě nové metody založené na algoritmu přímé lineární transformace (angl. Direct Linear Transformation, DLT): Metoda DLT-Plücker-Lines pracující s korespondencemi 3D a 2D přímek a metoda DLT-Combined-Lines pracující jak s korespondencemi 3D bodů a 2D přímek, tak s korespondencemi 3D přímek a 2D přímek. Ve druhém případě je redundantní 3D informace využita k redukci minimálního počtu požadovaných korespondencí přímek na 5 a ke zlepšení přesnosti metody. Navržené metody byly důkladně testovány za různých podmínek včetně simulovaných a reálných dat a porovnány s nejlepšími existujícími PnL metodami. Metoda DLT-Combined-Lines dosahuje výsledků lepších nebo srovnatelných s nejlepšími existujícími metodami a zároveň je značně rychlá. Tato disertační práce také zavádí jednotný rámec pro popis metod pro odhad pózy kamery založených na algoritmu DLT. Obě navržené metody jsou definovány v tomto rámci.

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.

FIT Inner Stereopanorama
Štechr, Vladislav ; Přibyl, Bronislav (referee) ; Juránková, Markéta (advisor)
This bachelor thesis is about combination of stereoscopic and panoramic photography. It describes creation of panoramas especially by stitching a set of images. Principles of depth perception and possibilities of stereoscopic images projection are discussed. This thesis includes software for presentation stereopanoramic pictures of Faculty of Information Technology interiors on the Internet and its description.

Correction of Geometric Distortion in Photographs
Cyprich, Miroslav ; Seeman, Michal (referee) ; Přibyl, Bronislav (advisor)
The resulting image of photographing is usually geometrically distorted. The most common of such distortions are called pincushion or barrel distortion, which can cause disturbing impression in photographs. There are currently several applications that allow to correct the geometrical distortion, but [proprietary, unergonomic, ...]. This paper describes the current state of knowledge in the field of geometric distortion correction and proposes a new software. An application with graphical user interface, whitch is focused on simplicity and ergonomics. It presents two possibilities of geometric distortion correction in photographs. Functionality and usability of the application has been tested and validated on a sample of real users

Photography Geotagging Application
Pavelková, Alena ; Přibyl, Bronislav (referee) ; Kubíček, Radek (advisor)
This bachelor's thesis describes photography geotagging -- finding and storing their position. There are mentioned several differed ways to geotag photos and explained related terms and needed technologies. Furthermore, there are introduced some existing applications for photography geotagging and described design and selected implementation problems of application created as part of this thesis. This application enables to geotag photos as a result of synchronization with route in GPX format or using map. There is described GUI, its parts and connections between them, used tools, and solutions to some problems.
