Design of Security Camera
Řihánek, Šimon ; Řezníček, Svatopluk (referee) ; Zvonek, Miroslav (advisor)
The subject of this bachelor’s thesis is to design a security camera, respecting the functional, structural, technological and aesthetic requirements. The aim is to create a design that would be elegant, universally applicable, would not appear too distracting, while still serving a preventive function.

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.

Identification of Persons in the Video from Quadcopter
Mojžiš, Tomáš ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
The aim of this thesis is to make an application capable of recognizing people's faces based on a user-created database in drone footage. The database is made of pictures of people that should be identified in the footage. The output of this application is a video where the demanded people are labeled with their names. Some face detection and recognition state of the art solutions based on neural networks are compared in this work. The final solution consists of the MTCNN detector and a face embedding extractor based on ArcFace. The created multiplatform application allows to recognize people in drone footage even with face width of less than 20 pixels. The final solution was tested on a private dataset comprised of drone footage.

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.

Estimate the Height of a Persons from the Video Data
Jelen, Vilém ; Orság, Filip (referee) ; Goldmann, Tomáš (advisor)
The aim of this bachelor thesis is to create an application that can detect pedestrians and make an estimate of their height from the video data. In the main part of the thesis I introduced security cameras and image processing methods suitable for detecting and classifying objects. Based on the comparison of these methods, I realized the pedestrian detection using Histograms of Oriented Gradients. As the input parameters of the proposed height estimation algorithm, I used the position and properties of the camera and reference objects or points.

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.

System for Guarding and Securing Objects and Areas
Komínek, Petr ; Schwarz, Josef (referee) ; Strnadel, Josef (advisor)
This bachelor´s thesis is about design and realization of electronic System for Guarding and Securing Objects and Areas. System is designed for small house. It has low supply, easy mounting and it is possible to change configuration. System can be controlled by keyboard as local or by GSM and Internet as remote. Events are written into history. Also is possible inform the user about events by SMS or E-mail. System includes automation module, object remote controlling and camera's system with Internet connection. Project is described with details about configuration of all components.
