A Hardware Platform for a Promotional Robotic Vehicle
Koláčný, Michal ; Burian, František (referee) ; Jirgl, Miroslav (advisor)
This thesis serves as a feasibility test for the construction of a robotic vehicle, where its autonomous movement will be provided by a camera and QR code scanning, for the company B:TECH. Specifically, it deals with the interaction of the hardware platform of the robotic vehicle together with selected electrical components. It describes the design of the structure printed on a 3D printer and its electrical and mechanical components enabling movement. Furthermore, the work focuses on the selection of suitable electrical components related to the safety of operation in the form of sensors. A necessary part is also the control and coordination of the movement of the vehicle using control microcontrollers. Specific components and equipment are described in the following chapters. The result of the thesis is the creation of a hardware concept of an autonomous robotic vehicle.

QR code detection using deep learning
Černohous, Matěj ; Kříž, Petr (referee) ; Přinosil, Jiří (advisor)
This bachelor thesis deals with the design of an algorithm for detecting and decoding QR codes in images using deep learning techniques. The work involved the construction of 2 datasets, a YOLOv7 neural network model for detecting QR codes in images, a YOLOv4-tiny neural network model for detecting position markers of QR codes, and a Python program utilizing these models to read QR codes in images. For evaluation, the algorithm was compared with other options for QR code reading.

Secure data transmition using bar codes
Kratochvíl, Martin ; Herout, Adam (referee) ; Beran, Vítězslav (advisor)
The goal of this thesis was to create a system for visual data transmition using bar codes. It focuses mainly on the protection of the system against abuse. A mechanism was designed for the data transmition itself and the various security concepts. The most appropriate bar code for data transmition was selected on the basis of the analysis.

SAP Modul for Encoding Invoices to QR Codes
Švancar, Boris ; Hrubý, Martin (referee) ; Kočí, Radek (advisor)
The master's thesis deals with encoding payment data invoices into QR codes in accordance with the by square standard. The SAP system along with a process of encoding data into QR codes and by square PAY standard is introduced in my thesis. In compliance with the standard function module is designed for the SAP system which is in the ABAB language, using Smartforms form allowing the QR codes to generate the invoice. The module is then subjected to testing. The results are evaluated in conclusion of the master's thesis and a description of potential further development is assessed as a final step.

Attribute Authentication on Android Platform
Strakoš, Jan ; Ricci, Sara (referee) ; Malina, Lukáš (advisor)
This master’s thesis focuses on implementation of ABC (Anonymous attribute-based credential) pilot system on the Android platform. The support for attribute authentication on the Android platform is very weak in terms of the number of implementations and needs a special attention. The theoretical part of the thesis describes the cryptographic support on the Android platform, the use of the Android Native Development Kit (NDK) and the Host-Card Emulation (HCE) service. The theoretical part of the thesis also includes a description of attribute authentication schemes, including a pilot RKVAC system. The practical part describes the implementation of the RKVAC system on the Android platform along with the implementation of a custom cryptographic kernel based on the native MCL cryptographic library. The practical part of this thesis describes implementation proces of RKVAC system on Android plaform, that uses native cryptographic library MCL. The final part shows the results of time, memory and computation difficulty of developed applications.

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.
