Movement Identification in the Space
Šolony, Marek ; Beran, Vítězslav (referee) ; Potúček, Igor (advisor)
The aim of this paper is to suggest optical system capable of movement identification in space and its reconstruction. The motion capture system uses markers attached to parts of human body, and a camera pair to capture the movement. This paper describes step-by-step parts of this system. Epipolar geometry is used to deal with problem of object correspondence between two views.

Acquisition and Recognition of 3D Signature
Molitoris, Miloš ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
This work deals with methods of signing in 3D space, selecting a suitable scan model, obtaining a sufficient number of samples to create a database, and finally verifying signatures. The first part deals with the issue of existing solutions and methods of signature verification, further image processing required for marker shooting in 3D space. The following sections are dedicated to design a unique signature solution in free space using a pen without any contact. Two shooting models have been designed using cameras or Leap Motion sensor. The application was implemented based on DTW algorithm using this sensor resulting in a dynamic signature verification system. Furthermore, the work includes a description using of database creation and experimental signature verification. At the end, we find an assessment of the security and error rate of the system that is compared to other methods. The result of this thesis is an application for 3D signature capture and recognition with the potential of a new technique for secure signature.

Application of ArcGIS Program in Telecommunication Networks
Štohanzl, Pavel ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
This thesis deals with the issues of locating and marking both metalic and optical transmission network. The choice of an appropriate program for creation and management of map document is discussed. In the following chapter some necessary adjustments to the ArcGIS ArcView program are made so that it is applicable to the field of telecommunication networks. The last chapter addresses the design of documentation options in optical transmission network. For metalic cables the possibilities of attaching transmitter to a cable and locating the induced magnetic field is covered. Among the methods for finding optical cables we list ways of locating through the use of markers, GPS location and added metalic conductors. Fundamentals of markers and their types are thoroughly analysed. In the chapter on GPS we examine how this system works and evaluate its accuracy. The next chapter enumerates requirements that a program should meet. We analyse properties of considered programs and evaluate them with respect to these requirements. For a chosen program the possibilities of enriching it with selected map document are discussed. For these map document, information about their applicability and source is presented. We also quote the cost for these maps wherever possible. The last chapter treats ways of documenting optical networks.

Augmented Reality in CAVE
Kolčárek, Michal ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
Tato práce se zaměřuje na technologii Cave Automatic Virtual Environment a konkrétně pak na využití principů rozšířené reality v tomto prostředí. Dává si za cíl odpovědět na otázku, zdali je možné použít v prostředí CAVE existující frameworky pro rozšířenou realitu, konkrétně ty, pracující na platformě iOS. Hlavní důraz je kladen na rozpoznávání markerů v tomto prostředí a na zvýšení přesnosti jejich rozpoznání. Práce odpovídá na množství otázek z této oblasti, jako jaké markery je vhodné použít, jaké jsou omezení a největší obtíže. Výstupem je demonstrační aplikace, pracující na platformě iOS, která v je prostředí CAVE otestovaná a plně použitelná. Tato aplikace by měla vylepšit uživatelský vjem z prostředí CAVE tím, že mu poskytne dodatečné informace a také základní možnosti interakce se zobrazenými objekty.

Synthesis and Detection of Color Markers for Augmented Reality
Beťko, Peter ; Szentandrási, István (referee) ; Herout, Adam (advisor)
This master's thesis emerges from the research in the field of uniform marker fields for augmented reality and broadens it by the possibility of generating colored marker fields based on arbitrary pictures. The thesis describes basics of augmented reality and explains the ideas from the Uniform Marker Fields paper. Presented is a program for generating colored marker fields as well as a tool for detecting markers and evaluating success rate of the detection. In addition, the work proposes a study of color constancy in the process of printing and recording. This study exceeds the scope of the requirements for this master's thesis; the knowledge can be used in arbitrary applications that use colors to code information. Finally, the integration of the knowledge into the marker field generating algorithm and resulting improvement of detection success rate are discussed.

Intelligibility of Lexical Units in the Extracts From Reading-Books for Pupils of Lower Secondary Schools
Pastýříková, Barbora ; Nedvědová, Blanka (advisor) ; Hájková, Eva (referee)
This bachelor's thesis deals with the issue of comprehensibility of lexical units in examples from reading-books for lower secondary school pupils. The work is divided into a theoretical part and a practical part. The theoretical part deals with lexicology and individual concepts that relate to this linguistic discipline and the subject of research. It also includes a discussion of writing style, current research, the concept of teaching the Czech language and the relationship of RVP to teaching vocabulary. The practical research part presents and interprets data obtained from quantitative and qualitative research conducted at two schools. The research was carried out using a questionnaire survey and subsequent interviews with pupils of the 6th and 9th grades of lower secondary school. The questionnaires contained the highlighted lexemes under study in excerpted sentences selected from the reading books intended for the respective classes. The aim of the research was to find out whether the pupils understand the words listed in the questionnaire, whether they can explain them or replace them with synonyms or whether they can derive their meaning from the context of the sentence. In our work, we focused on words that appear in fictional writings and which we evaluated as challenging to explain...

Genotypization of selected candidate markers for resistance against lentiviral infections of small ruminants
FARKOVÁ, Barbora
Small Ruminant Lentiviruses (SRLV) known as maedi-visna in sheep, and viral arthritis and encephalitis in goats are widespread worldwide and cause significant economic losses. Lentiviral diseases have been included in the current Animal Health Control and Vaccination Guidelines for Breeding Controls. Control programs are generally based on serological screening and subsequently serologically positive animals are removed from breeding. In the literature review I write about important lentiviruses, including those that have not been analyzed. The aim of this work was to screen for the occurrence of lentiviral infections in small ruminants in the Czech Republic and the genotyping of selected candidate markers and finding the genotype related to the possibility of gene resistance. In total, over 3200 blood samples were collected from sheep and goats from breeders all over the Czech Republic. Genotyping was carried out in herds where serologically positive animals were detected. Amplification of the DNA sequence of interest was performed by PCR (Polymerase Chain Reaction) analysis, followed by genotyping by sequence analysis, and the results were statistically evaluated. In my work, I came to the conclusion that in the Czech Republic the occurrence of 2 out of 5 possible SRLV genotypes (genotype A and B) and distribution of different subtypes in sheep and goats has been detected so far. The greatest differences were in the sequence of genotype A, where one group of isolates showed the possibility of classification into a completely new subtype. In sheep, all three genotypes of the TMEM154 gene were identified. The incidence of serologically positive was statistically significantly higher in animals with a risk genotype. Because of the possible mutation of the virus and the emergence of a new subtype of genotype A, the virus is more likely to adapt to attack and infect individuals with a more resistant genotype. Only one genotype has been demonstrated in goats, so most likely there is no marker associated with resistance to SRLV infections.
