Automatic Acquisition of Data from the Internet for Training of Recognizers
Jeřábek, Jan ; Glembek, Ondřej (referee) ; Szőke, Igor (advisor)
This paper describes the design and creation of an application to facilitate downloading of audio data from Internet for training recognizers. Focuses on selection of optimal data source and analyzes options for searching and downloading from selected medium. On this base appropriate selection of tools and libraries is described. Description of the implementation follows where key parts of application are described. In the conclusion are summarised the achieved results and proposal for futher development.

Mobile Application of Image Processing
Planer, Jan ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
This thesis addresses video streaming from smartphone to smartwatch. The main goal of the thesis is to find a way how to handle the limited hardware features of the watch and make video streaming as fast and smooth as possible. A part of this work is focused on implementation of client-server application, which streams video from Android device to Tizen smartwatch over Bluetooth channel.

Advanced algorithms for compression of video sequences with ultra high resolution
Soukeník, Ondřej ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This bachelor thesis provides an overview of advanced video codecs and explores their applicability for compression ov videosequences in ultra high resolution (UHD). The thesis is divided into two parts, theoretical and experimental. The theoretical part of the thesis gives an overview of advanced video codecs for video compression. Furthermore, objective metrics used for evaluation of the quality of a compressed video are briefly described. This part of the thesis also contains a detailed description of the created tool, employing a reference implementation of the selected video codecs, for easy compression of video sequences in UHD. This tool is used in the experimental part to compress different video sequences. The compression efficiency of each video codec is evaluated in terms of different objective metrics. Furthermore, the Bjntegaard Delta analysis is employed to obtain infromation about the compression efficiency of the used video codecs.

3D Video Browser
Míchal, Vít ; Štancl, Vít (referee) ; Beran, Vítězslav (advisor)
The aim of this project is to design and create application for the visualization of interconnected video data. Visualization takes place in 3D space and seeks to exploit its advantages (such as depth perception). This document contains survey to different categories of spatial user interfaces. In addition, includes three possible designs of user interfaces and control. Implementation details and made usability tests are also described. Application is implemented in C++ using Open Inventor. The document includes evaluation of the results and made tests.

Video Library for Android Platform
Slavotínek, Tomáš ; Polok, Lukáš (referee) ; Láník, Aleš (advisor)
This thesis deals with processing of video content on Android platform. Libraries for video encoding and decoding usable on this platform are described first. One of these libraries - FFmpeg - is used as core to design and implement middleware video-processing library. This library will provide simple but e fective API for multimedia Java applications.

Videocodec - Videosequence Compression
Bařina, David ; Motlíček, Petr (referee) ; Smrž, Pavel (advisor)
This thesis deals with modern methods of a lossy still image and video compression. Wavelet transformation and SPIHT algorithm also belong to these methods. In second half of this thesis, a videocodec is implemented based on acquired knowledge. This codec uses Daubechies wavelets to analyse an image. Afterwards there is a modified SPIHT algorithm applied on gained coefficients. A lot of effort was put in order to optimize this computation. It is possible to use the created codec in Video for Windows, DirectShow and FFmpeg multimedia frameworks. At the end of this thesis, commonly used codecs are compared with newly created one.

Web Browser for IP Cameras
Černý, Pavel ; Veigend, Petr (referee) ; Zbořil, František (advisor)
The aim of the work described in this thesis was to enable live video streaming from IP cameras to selected users, using simply a modern web browser with no need to install special client-side software. The solution was found by utilizing programs FFmpeg (for communication with camera and video conversion to WebM format), Stream-m (for distribution of the data received from FFmpeg to clients), and a newly-created web application built on the Spring framework, which was used to control the aforementioned programs, and also allows camera management and user authorization. The resulting system reduces the effort required for client nodes deployment and maintenance. Thanks to the image size downscaling, the system brings about a considerable reduction of data flow in the network caused by camera output, and minimizes the load on client computers.

Audio/video streaming
Čeněk, Radek ; Jeřábek, Jan (referee) ; Číka, Petr (advisor)
This thesis introduces the reader in detail with the problem of audio / video streaming overtheInternet.IntroducestechnologiesMySQL,PHP,JavaScriptandffmpegfurthermore. There is little research which examines presented similar solutions. Creating video library program shows the complexity of the problem and its possible solution. The work also finding how is compression difficult for the server.
