Control and acquisition of data from camera sensor OV2312
Kováč, Dávid ; Kříž, Petr (referee) ; Přinosil, Jiří (advisor)
This bachelor thesis deals with the implementation of a driver for the camera sensor OV2312 into the libcamera framework, with the creation of an API interface that allows direct frame capture from a camera in the C++ language and with the creation of a program for demosaicing raw data from the camera sensor for the Raspberry Pi platforms. The aim of this thesis is not only the creation of software that would allow the camera sensor OV2312 to work with Raspberry Pi computers, but will also provide extended control options. The theoretical part describes the single board computers Raspberry Pi, the Libcamera library, the demosaicing process and the troubleshooting procedure. The output of the thesis is a modified Libcamera library that allows the user to capture images and change the parameters of the camera sensor. The created library for direct access to the camera in the C++ language allows to expand the capabilities of the camera sensor. The program for demosaicing provides the user the ability to convert raw data into images.
Data collecting tool from the open-source datasets
Kříž, Petr ; Martinásek, Zdeněk (referee) ; Gerlich, Tomáš (advisor)
The thesis examines the field of intelligence disciplines in detail, with an emphasis on open source intelligence (OSINT). The thesis includes a detailed description of the intelligence cycle, including an analysis of the different phases of the cycle. Furthermore, the theoretical part of the thesis provides a overview of the social network Instagram from an OSINT perspective. This includes a description of the types of data available on this platform and the methods that are used to collect it. The practical part then demonstrates the design and implementation of an open data monitoring tool on Instagram. This tool is designed to monitor public posts and comments on Instagram. The main output of this thesis is a functional tool that not only collects data but is also able to visualize this data effectively.
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.
Creation of the Graphic Library for VST Plug-Ins
Dufka, Filip ; Kříž, Petr (referee) ; Přikryl, Lubor (advisor)
Master‘s thesis covers use of graphical user interface in audio plug-ins. In first part structure and rendering techniques of audio plug-ins graphical libraries are described. Their efficiency and their way of memory utilization is questioned. Next part puts these techniques in comparison with the state of the art methods used in computer graphics and gaming industry. Their possible use in audio graphical interafaces is analyzed. In the following part, thesis finds solutions to uneffective methods in frequently used situations by presenting deferred shading into audio parameter editor with the goal of photorealistic rendering. Second introduced technique of „Knob Normal Maps“ reduces number of images needed for rendering of turning knob from hundereds to six with comparable results. Goal of diploma thesis was to create graphical library. Graphical library with name RealBox was created, and introduced techniques are the core features. Library reduces work needed to achieve graphical user interfaces for 2D and 3D cases of use. Full class and method documentation for RealBox library was assembled. Library was tested during creation of three VST plugins, with different approaches and emphasis on quick work and fine rendering. Graphical library offers new, faster way of creating audio plug-in interfaces.
Optimization Rewarding Shareholders Ltd
Hlavatá, Yvona ; Kříž, Petr (referee) ; Kopřiva, Jan (advisor)
This Bachelor thesis is focusing on possible forms of remunerating members of a limited liability company. It analyses the existing way of remunerating a member of a particular company and by means of created models of remuneration it is looking for the most optimal combination of paying out a share in profits, remuneration on the basis of the commercial-law relationship and salary on the basis of the labour-law relationship from the point of view of the tax burden, including the social and health insurance payments by this company.
Online vibration diagnostics of the DATRON milling machine spindle
Kříž, Petr ; Hammer, Miloš (referee) ; Jankových, Róbert (advisor)
This master’s thesis deals with online vibration diagnostics of the milling machine spindle. It is aimed at the implementation of the complex online vibration diagnostics system to chosen milling machine, the suggestion of the vibration measurement system and the suggestion of the evaluation of changes of the technical condition of this milling machine spindle. The description of the vibration diagnostics, the description of the milling machine spindle construction and function and the suggestions for the practical application of vibration diagnostics are also parts of this thesis.
Development of a PLC code generator for faceplate blocks for S7-1200, S7-1500, S7-300/400
Kříž, Petr ; Weber, Martin (referee) ; Pásek, Jan (advisor)
The main goal of this bachelor’s thesis was creating a tool for generating PLC code according to entered data. Generator works with function blocks that are assigned to each faceplate object from faceplate library provided by COMPAS Automatizace, spol s.r.o. Source file is created from generated code and program blocks in program TIA Portal V13 are created from this source file.
Optimalization of internet presentation for e-marketing maintenance
Kříž, Petr ; Luhan, Jan (referee) ; Dydowicz, Petr (advisor)
Bachelor’s thesis is construct methodistic directions for profit new possible customers from internet medium with using an optimization techniques for internet presentations. Optimization techniques are divided for full and implicitly suggestible factors. These factors are combinable with internet marketing.
4K real-time video encoding using NVENC technology
Buchta, Martin ; Přinosil, Jiří (referee) ; Kříž, Petr (advisor)
Diploma thesis is focused on real-time 4K video encoding using NVENC technology. First chapter describes the most used video codecs H.264 and HEVC. There is an explanation of the principle of graphic cards and their programmable units. Analysis of the solution of open source Video Codec SDK is also part of the thesis. The main focus of the thesis is an implementation of an application which can handle 4K video encoding from multiple cameras in real time. Performance and qualitative tests were performed for application. Results of these tests were analyzed and discussed.
Detection of changes in digital images
Dorazil, Jan ; Kříž, Petr (referee) ; Říha, Kamil (advisor)
This thesis concerns with change detection problematics in digital images captured under indoor conditions with an ordinary integrated camera in two consecutive moments. All challenges that accompany this problem will be discussed, starting with preprocessing and arriving to evaluation of the results. Currently used methods from this field are described and compared with each other such as differencing and LCP (Local Correlation Peak). A novel method, based on LTP descriptors, effectively solving this problem is proposed in this work. The proposed method is then tested on real data. The results of this tests are discussed subsequently. Besides the change detection method a method for parallax error minimization is proposed here.
