QR Code and decoding
Zajíčková, Adéla ; Drápal, Aleš (advisor) ; Šťovíček, Jan (referee)
The aim of this paper is to descript QR codes. First of all we focus on a description of a structure and then we deal with decoding, more specifically with the part which uses the theory of error-correcting codes. From the viewpoint of this theory QR codes can be perceived as an instance of Reed-Solomon codes. For that reason the paper deals with elementary properities of RS codes and with one of the technique of decoding, concretely Euclidean decoding algorithm. An example shows the knowledge and futhermore the paper includes detailed description of mathematical principle of used algorithm.

QR code detection under ROS implemented on the GPU
Hurban, Milan ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
Tato diplomová práce se zabývá vývojem a implementací algoritmu pro detekci QR kódů s integrací do platformy ROS a výpočty běžícími na grafické kartě. Z rešerše současně dostupných nástrojů a technik je vybrán vhodný postup a algoritmus je napsán jako modul v programovacím jazyce Python, který je snadno integrovatelný do ROS. Ke zprostředkování výpočtů na vícejádrovém hardware, jako jsou grafické karty či vícejádrové procesory, je využita knihovna OpenCL.

The concept of an information retail technology
PUCOVÁ, Alena
Information technologies are very important for many people because the technologies are used every single day. This thesis deal with applying information technologies in the chosen retail chain Globus České Budějovice. One specific technology (Scan&Go) is chosen for research and the aim is to find out the customer´s opinion about this technology. The thesis describes the information systems and the newest technologies. This thesis also explains concepts like a QR codes, virtual dressing room or information kiosks. Literature and internet resources are used for study about this issue. The quantitative marketing research is one of the best option for getting right information about this topic, because specific information is needed. The method inquiring "face to face" is used because of personal contact with customers. The data are processed in a special computer program PSPP. This gained information is very useful for confirming or refutation the hypotheses. One part of this thesis are recommendations for future.

Monitoring System Communicating with Mobile Device
Ilavský, Filip ; Šimek, Václav (referee) ; Očenášek, Pavel (advisor)
This thesis deals with design and implementation of hardware peripheral measuring temperature, and implementation of client application, displaying the measured data. Wireless communication between the peripheral and the client is implemented under the protocol Bluetooth Smart (version 4.0 and higher) and secured by a security protocol against the attacker capturing this communication. The result of this thesis is a fully functional peripheral prototype measuring temperature and application displaying this temperature, designed for iOS version 8.0 and higher.

Security applications on the Apple iOS platform
Kolář, Michal ; Martinásek, Zdeněk (referee) ; Hajný, Jan (advisor)
This document deals with the security of iOS operating system. It describes applications which ensure the safety of the entire file system and private files of the user. It further describes mechanisms for authentication of the user and for credibility verification of third- party applications. The practical part is devoted to the installation of the development environment Xcode and introduces the reader to its work environment. The practical part is focused to create an application which will implement a security protocol. Also include work with another additional libraries which will be needed to create an application. Output application will be generated QR code with all required values of cryptographic protocol

Android Application for Gas Furnace Servicemen
Podola, Adam ; Maršík, Lukáš (referee) ; Szőke, Igor (advisor)
This thesis describes the required specifications as well as the design and implementation of an application for devices running Android operating system which is primarily used by service technicians of gas boilers. This application allows the creation of an appropriate knowledge base which is useful for operations performed by a service technician. The application user interface is based on the functionality provided by the fragments. SQLite database is used in combination with an external storage device to preserve data.

Decoding Barcode in Image in Real Time
Krupa, Martin ; Kajan, Rudolf (referee) ; Herout, Adam (advisor)
The goal of this thesis is to describe barcodes used in real world applications and to create application for real time detecting and decoding of chosen barcodes using computer vision. Normal linear barcode is first introduced, and then two dimensional matrix barcode is described with focus on its origin, usage and structure. Especially the process of localization, encoding and decoding of QR Code, which is chosen for future use in work, is described mainly. Also briefly description of computer vision and OpenCV library is available. Next the concept and implementation of application for localization and recognition of QR Codes is described. Finally description of testing, evaluation of thesis and ways of improvements are discussed.
