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.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Detection of the Cars Approaching the Crossroad
Hopjan, Tomáš ; Peringer, Petr (referee) ; Rozman, Jaroslav (advisor)
This project deals with monitoring cars approaching the crossroads. Describes various methods of detection and discussing their problems. Primary goal is surveillance during the day in different weather conditions, but method of detection cars during the night and low light is also introduced. The most widely used algorithms are implemented using the OpenCV library. Important part is testing different algorithms and also variety of lighting conditions, camera locations and settings.

Miniature Tracking Device
Šťáva, Radek ; Levek, Vladimír (referee) ; Macháň, Ladislav (advisor)
The main theme of this masters's thesis is to design and make a miniature universal tracking device. This device is primarily for tracking asset, pets or people. For detecting the position data is used GPS technology. Data transmission is carried out via the GSM network. The device is technically solved and realized with respect to miniature size, high battery life and with regard to resistance against water, dust and impact damage. It is selected unique design, suitable for hermeticaly closure of the entire facility. Due to hermetic closure there is any buttons, any connectors and the battery charging is wireless.

Detection, Tracking and Classification of Vehicles
Vopálenský, Radek ; Sochor, Jakub (referee) ; Juránek, Roman (advisor)
The aim of this master thesis is to design and implement a system for the detection, tracking and classification of vehicles from streams or records from traffic cameras in language C++. The system runs on the platform Robot Operating System and uses the OpenCV, FFmpeg, TensorFlow and Keras libraries. For detection cascade classifier is used, for tracking Kalman filter and for classification of the convolutional neural network. Out of a total of 627 cars, 479 were tracked correctly. From this number 458 were classified (trucks or lorries not included). The resulting system can be used for traffic analysis.

Person Identification for Surveillance
Hopjan, Tomáš ; Juránek, Roman (referee) ; Hradiš, Michal (advisor)
This project deals with camera system surveillance and identification of humans. Motion detection and identification methods are presented. The main issue is people tracking using multiple camera system. Identification of individuals is accomplished using processing of decomposed colors histograms. Based on the experiments benefits and problems are introduced.

Intergenerational comparison of reasons and motivations for not watching television
Florián, Petr ; Reifová, Irena (advisor) ; Vochocová, Lenka (referee)
This thesis focuses on an intergenerational comparison of reasons and motivations for not watching television broadcasting. The aim of the research is to find out why people do not watch television broadcasting and what activities they substitute for this activity. Then the differences between the responses of the first target group, which includes people aged 20-30 who do not watch television broadcasting, and the responses of the second target group, which includes people aged 50-60 who do not watch television broadcasting, are compared. The theoretical part focuses on the historical background of television, mass audience, post- broadcasting age, television viewing, leisure and digital detox. The next part of the thesis discusses the methodology that was used for the research part. The practical part focuses on the categorization and interpretation of the semi-structured interviews with the respondents. The research was conducted in the spring of 2023. The data then shows a number of findings regarding not only what the respondents' main reasons for not watching television are and what they substitute for this activity. At the very end of the paper, a transcript of one of the interviews is also included to give an example of how the semi-structured interviews were conducted.

Shadows have eyes
Grűnwaldová, Glorie ; Nádvorník, Filip (referee) ; Artamonov, Vasil (advisor)
My Bachelor thesis continues in longer-term work, which is spinning around curiosity, feeling of being watched and maybe even paranoia. It is based on my own experiences, which are related to today's digitized world. We can argue about whether there is privacy or we really live in a place of easily detectable information. These experiences are also based on anxiety and some sort of self control. In my paintings I try to move over the weight of this theme and work with humor. There are moments that make no sense, they are stylized into exaggerated form. The expression of the image is also important, painting itself and combination of techniques. My main goal is to share, lighten these experiences, but also transfer energy throughout the painting.
