Intelligent Security Camera Based on Raspberry Pi
Vinarčík, Peter ; Španěl, Michal (referee) ; Materna, Zdeněk (advisor)
The aim of this thesis is to create Pan-Tilt-Zoom security camera which will be constructed from Raspberry Pi and camera module. Camera tries to be compliant with ONVIF standard. Software of this camera is implemented in Python and partially in Node.js. Camera module captures 200 degrees field of view. Captured image is transferred as simulation of Pan-Tilt-Zoom camera with the help of computer vision - library OpenCV for Python. The resulting image will be possible to control and watch in network video recorder called Shinobi.

Wireless robot control using mobile platform
Matuška, Jakub ; Kiac, Martin (referee) ; Přinosil, Jiří (advisor)
This bachelor’s thesis deals with design and implementation of an application for robot’s omnidirectional movement control using mobile platform. Implementation includes an Android application, used as user interface, as well as robot–side Python program for controlling movement and sending RTP stream to Android application. User can control robot’s movement using two virtual joysticks. Raspberry Pi was used as the control unit. The application has security module. Pipeline-based multimedia framework named GStreamer was used to implement RTP steaming. This paper describes necessary theory first and then introduces basic building blocks used in creation process of the application.

Video Capture and Compression on Embedded Devices
Dušek, Oto ; Chlubna, Tomáš (referee) ; Bařina, David (advisor)
Industrial cameras are often used in conjunction with the application of machine learning. However, these cameras produce large bitrate and it needs to be reduced when processing video further away from the camera. This thesis tries to solve the problem by design of system suitable for grabbing video from industrial cameras, its compression and distribution to machine learning application. The thesis describes technologies applicable to the development of the multimedia application. For example frameworks FFmpeg and GStreamer were used implementation of the system.

Comparison of Multimedia Frameworks
Brandejs, Zdenko ; Klíma, Ondřej (referee) ; Bařina, David (advisor)
The aim of this work is to create a comparison of the most famous multimedia frameworks according to supported platforms, formats and usage. To familiarize with a multimedia frameworks and their libraries for work with multimedia. Concretely with Video for Windows, DirectShow, Media Foundation, FFmpeg, GStreamer, xine and QuickTime. Describe in detail, how separate technologies work including their architectures. Building web tutorial, where will apply theoretical knowledge during creating players.

Video mixer/translator for web-based videoconference system
Hutar, Jan ; Balík, Miroslav (referee) ; Číka, Petr (advisor)
Bachelor s thesis specialises in a basic description, comparing and processing of video standards H.264 and VP8 in real time. Particularly it concerns a support of videoconfe- rence systems working with those mutually incompatible standards. The work enquires and tests two most considerable software devices convenient with basic requirements for working with video in real time and available with LGLP licence respectively FFmpeg and GStreamer. The thesis suggests practice video mix implementation of data input and the way of code translation into required outgoing stream. FFmpeg tool has been used for realization and message of mixer/translator and simple interface has been established available from web browser with assistance of HTML, PHP and Javascript.

Embedded Vision System on NVIDIA platform
Krivoklatský, Filip ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with design of embedded computer vision system and transfer of existing computer vision application for 3D object detection from Windows OS to designed embedded system with Linux OS. Thesis focuses on design of communication interface for system control and camera video transfer through local network with video compression. Then, detection algorithm is enhanced by transferring computationally expensive functions to GPU using CUDA technology. Finally, a user application with graphical interface is designed for system control on Windows platform.

Mobile Robot with Telepresence Control
Svědiroh, Stanislav ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This thesis deals with the proposal and implementation of a robotic platform for the purpose of visual telepresence. The aim of the work is to create a robotic platform remotely controlled by a virtual reality headset, being capable of moving on a flat surface and rotating the camera plaform in two degrees of freedom independently. This work provides a complete solution - both in terms of software and hardware.

Design of adaptive wireless video and data transmission
Lorenc, Tomáš ; Nykodým, Jiří (referee) ; Götthans, Tomáš (advisor)
Cílem této diplomové práce je sestavit zařízení, které bude umět vytvořit bezdrátový přenos real time videa a posílat video do počítače, kde bude zobrazeno. Zařízení je postavené na jednotce NVIDIA Jetson Nano a vysílání videa probíhá bezdrátově pomocí WiFi rozhraní. V teoretické části je popsána problematika přenosu videa a komprese videa. Používají se kodeky h264, h265 a VP8. Byl proveden subjektivní test pro nalezení minimální akceptovatelné hodnoty kvality videa. Bylo provedeno měření, které odhalí nejlepší kodek pro real time přenos videa. Měření probíhalo i v reálných podmínkách. V závěru jsou komentovány výsledky měření a výběr nejlepšího kodeku pro real time video přenos.
