2D barcode recognition system
Sedlář, Martin ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
This bachelor’s thesis deals with 2D barcode reading. At the beginning a brief overview of the most used barcodes is shown. The work mainly deals with QR codes. Their structure, composition and rules for encoding and decoding are explained. Problems with arrangement of photographic scene are solved too. C++ algorithm for QR code reading is described with usage of the OpenCV library.

Barcode recognition system
Pribula, Wojciech ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
This thesis describes barcodes which are used in postal services. Specifically, it is concerned with Intelligent Mail Barcode, the GS1-128 code, the C128 code of Ceska posta (Czech Postal Services) and the QR code. The thesis attempts to analyze methods of encoding information into barcodes and error detection algorithms used for error correction during the decoding processes. Most importantly, there is described Reed-Solomon error correction in the QR code. There are presented and evaluated different methods of code detecting which are suggested by authors of various academic articles. The thesis also describes the method of creating test sets of images and proposed appearances of the scanning scene. Additionally, there are described algorithms for detection and decoding barcodes GS1-128, C128 and IMB in the image which was created during the work on this thesis. Finally, there is the evaluation of the percentage success of algorithms.

User verification based on smart-phones
Bělík, David ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
The main aim of this diploma thesis is to get acquainted with the area of secure authentication and authorization of users in smartphones on the Android platform. Individual types of encoding, authentications, authentication devices and characteristics of QR codes are decribed in the chapters. In the practical part of this thesis the applications are created with an implemented authentication scheme, which is being developed at FEKT VUT in Brno. The client part of the application, that generates QR code, as well as the server part, that verifies the authenticity of the data, are set up.

Web applications for user authentication
Vybíral, Petr ; Dzurenda, Petr (referee) ; Hajný, Jan (advisor)
The thesis deals with the problems of user authentication. The first chapter analyzes the problem of authentication, its methods and its utilization. The second chapter presents the different security options for communication. The chapter describes security, communication and authentication protocols. There is the 2D barcode QR Code described at the end of the chapter. The third chapter is devoted to ASP.NET technology, its development and possibilities of utilization. Attention is focused on web form and server controls. There is an analysis of elements of cookies and possibilities of their use. The last chapter consists of a practical part, which describes the development of a web application. There is a description of the parts of application, such as the database, the Web navigation, master pages and etc. in the following chapter. The cardinal part of the chapter consists of an analysis and implementation of forms authentication, the attribute authentication and authentication with QR code. Finally, there is a description of way how to secure the communication by using a certificate.

Advanced QR-Code reader for Android
Kubík, Martin ; Přinosil, Jiří (referee) ; Šmirg, Ondřej (advisor)
The aim of this diploma thesis was to created application for detection and decoding QR codes using devices with the Android Operating System. For preprocessing of the visual field camera is used OpenCV library. Designed preprocessing string searches a perspective transforms possible QR codes. This is suppressed a shape distortion QR code that would otherwise reduce the successful decoding. At the same time the preprocessing string applied unsharp mask, which reduces the effect of motion blur image caused by the camera motion. Thus preprocessing scene is finally decoded using ZXing library. Described manner it is possible to achieve a higher success rate detection and decoding of QR codes than other conventional QR readers.

Embedded QR code generator with a graphic OLED display
Lakomý, Tomáš ; Krajsa, Ondřej (referee) ; Hanák, Pavel (advisor)
This master’s thesis deals with coding information and QR codes generating. There is described operation principle of QR codes for this purpose, and design of the equipment. This device is able to encode the information received through the serial port and display it in the QR code on the OLED display. Microprocessor is part of the device, so there is outlined the procedure for programming and testing equipment.

Development and publication of an application on Android platform
Plevka, Ondřej ; Pavlíčková, Jarmila (advisor) ; Šlajchrt, Zbyněk (referee)
The aim of this bachelor's thesis is to gradually familiarize the reader with the development process and publication of an application on the Android mobile platform. This is the practical part of this thesis. The application deals with the dynamic collections management based on barcodes or QR codes. Among other things, the application can communicate with a remote database on the web server. The gradual process of development as analysis, design and subsequent publication are described in the theoretical part of this thesis. The last part discusses the possibilities of promotion applications on the Internet.

The folk culture as a factor of tourism development in the region of Valašsko
BLÁHOVÁ, Petra
The aim of this thesis is to highlight the importance of folk culture for tourism development and to suggest options for better evaluation and effective use of the potential of folk culture tourism in the selected region based on the results of the analysis in the region of Wallachia. In the introduction of the practical part I deal with the current supply of Wallachia. The fundamental part was quantitative marketing research in the form of a questionnaire survey. The aim of the survey was to identify the participants of tourism in terms of demographic characteristics, determine the purpose of the visit, analyse their financial expenses, and identify subjective perception of culture and assessment of infrastructure and services in the region. I designed a new product called "Wallachia hunt", which aim was to involve young people in the Wallachia culture, tourism allows participants to actively and an interesting way to travel around the region and specifically to discover its natural and cultural wealth. "Wallachia hunt" is based on the worldwide known activity called geocaching. In my work I have put together a detailed proposal for annual testing of this activity.

Payment for goods and services via mobile communication
Roman, Martin ; Pavlíček, Antonín (advisor) ; Exnarová, Anna (referee)
The aim of my work was to analyze actual possibilities of payment by mobile communications, focusing on the European Union and to detect on the basis of a survey how the current services are used and how they are perceived by users. Next, there is suggested own solution of using mobile phones for payments with the present conditions. The work includes a case study which focuses on mobile micro-payments and involves currently used solutions for these payments in the Slovak Republic. The work is divided into three parts. The first part contains a definition of the mobile payments, explains words which are related to the work and analysis of the current payment options with comparing payments via mobile phones. The second part analyzes the most used payment options via mobile phones and their use in different regions of the world. The third part consists of evaluate analyze, a concept of own solution for mobile payments, a case study of micro-payments and the questionnaire.
