Easily Configurable Visual Inspection System for Industrial Applications
Andrla, Ondřej ; Špaňhel, Jakub (referee) ; Španěl, Michal (advisor)
The aim of this thesis is to create a prototype of an easily configurable camera system, used to control products on an automated assembly line. The thesis is especially focused on the issue of LED detection. Their very presence in the image is detected and the system also evaluates whether the LED is lit and, if so, in what color. The final solution allows the user to easily define control metric for searching for circular objects in the image in a configuration application with a graphical user interface. The configuration is saved in a JSON file. Furthermore, a runtime which independently processes the recording from the camera, checks the products and reports on them to other components of the system based on the configuration was implemented. The system uses the Hough circular transformation to detect objects in the image. To test the efficiency of the system, a dataset was created using the FitKit tool with a LED matrix. When testing the runtime on the dataset, the overall accuracy of LED detection was 97,79%.

Monitoring and Security System
Felix, Martin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This master's thesis deals with design and implementation of system for securing and monitoring objects. The whole system is serving as an application getaway between typical TCP/IP network and heterogeneous network containing different end devices such as security cameras, microphones and some sensors (e.g. for temperature measurement). In case of detected event, the notification is created, recorded and the user is informed via administrative front-end. System can be managed from remote location and data from devices can be shown by web interface. Theoretical part of this project concerns with the analysis of different types of connecting devices and sensors and the possibilities of their usage for the monitoring systems along with description of communications protocols for each end device. The next part deals with the cameras interfaces, content analysis and connectivity with central server. Practical part describes methods and techniques used for implementation of system.

Cybernetic applications against COVID-19
Hyhlík, Pavel ; Lázna, Tomáš (referee) ; Chromý, Adam (advisor)
This bachelor thesis deals with possible solutions of the COVID-19 crisis, with the help of knowledge in the field of cybernetics. It describes problems that cause spread of the disease, precautions that have been made and possibilities for improvement of their efficiency using this specialization, or also new solutions. The advantages and disadvantages of particular solutions and their effect on spread will be analysed as well. A system for spacing monitoring is chosen and constructed from them.

Reconstruction of Facial Images Using Neural Networks
Zubalík, Petr ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
The main purpose of this bachelor's thesis is to propose and implement a model, using neural networks, that will be able to reconstruct low-resolution facial images with blurry parts of the face. The task of super-resolution of facial images is solved by two models based on convolutional neural networks. The first model is built upon the architecture of ResNet whereas the other model makes use of the principles of generative adversarial networks. The proposed models are implemented in the Python programming language with the use of application programming interface of the TensorFlow framework. Moreover, as a part of this work, an application with a simple grafical user interface was created. This application makes it easy to use the implemented models. Several experiments are analyzed in the last chapter of this thesis to evaluate the performance of the models.

Detection of Anomalies in Pedestrian Walking
Pokorný, Ondřej ; Orság, Filip (referee) ; Goldmann, Tomáš (advisor)
The goal of this work was to create a system that would be able to detect anomalies in pedestrian walking. As the core of my application, I have used OpenPose, which is an application for detecting human skeletons. Then I used a bidirectional LSTM neural network to detect anomalies in video sequences. This architecture was chosen during the experiment because it outperformed other solutions. I trained my model to detect three types of anomalies. The output of my application is a video with marked sequences of anomalies. The whole system is implemented in Python.

Camera surveillance system
Lazarević, Veljko ; Přinosil, Jiří (referee) ; Koton, Jaroslav (advisor)
The bachelor thesis is focused on the introduction and design of a camera system. The theoretical part briefly deals with the description of individual components and basic parameters of the camera system, especially the personal protection. Security systems today rely heavily on cameras. Cameras can be useful in identifying potential threats and protecting people and property. It is important to take precautionary measures to protect yourself and your property. This bachelor thesis deals with various camera systems, namely analog, hybrid and currently digital. The practical part is about the design, installation and maintenance of a digital camera system.

Design and Implementation of a System for Checking the Boxes Completeness
Filipský, Dalibor ; Pásek, Jan (referee) ; Jirgl, Miroslav (advisor)
This thesis describes the design and implementation of a system for checking the boxes completeness. Thesis is divided into several parts. The first part includes an introduction into the manufacturing process and also devices, for which the system is designed. The second part consists of system design and a description of hardware components used for the system. The third part deals with the creation of a scheme used for connection an electrical switchboard. The fourth part is focused on a design of mechanical constructions, such as construction plan used for vision sensors connection, lighting system and design mechanical parts of stopper. A simulator of the system for checking the boxes completeness is described in the fifth part. It is used for a demonstration of functionality and controllability of the system. The sixth part deals with enabling of a communication between particular sub-systems, such as vision sensors, control panel and control system. The seventh part is focused on creation of the software required for the control system, HMI panel and deals with the configuration of pair vision sensors. In the final part there are some illustrations of designed system in real process of manufacturing.
