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.

USB a FireWire camera aplications
Berka, Petr ; Janáková, Ilona (referee) ; Richter, Miloslav (advisor)
This diploma thesis deals with a interface USB and FireWire cameras to a computer through a technology called DirectShow. I used mostly a development kit „MontiVision“, which cooperates with a programming environment as is e.g. Microsoft Visual C++. You find here how to use a direct pixel access, how to get singles photos from a video, how to set up and calibrate a camera and how can look a particular application of the image processing. I wrote an introduction to the stereo-vision above the frame of my task. This thesis is like a manual for students. It includes my personal experiences and experimentations too.

Lossless Video Compression
Němec, Jaroslav ; Polok, Lukáš (referee) ; Bařina, David (advisor)
This master's thesis deals with lossless video compression. This thesis includes basic concepts and techniques used in image representation. The reader can find an explanation of basic difference between lossless video compression and lossy video compression and lossless video compression limitations. There is also possible find a description of the basic blocks forming the video codec (every block is described in detail). In every block there are introduced its possible variants. Implemented lossless videocodec was compared with common lossless videocodecs.

Videocodec - Videosequence Compression
Vančura, Jan ; Herout, Adam (referee) ; Sumec, Stanislav (advisor)
This thesis is concerned with design and implementation of application for video compression. Application is implemented with programming language C++ in Microsoft Visual Studio 2005 by using library Video for Windows and DirectShow. It is focused to decrease size of video data stream. It describes lossy and lossless data compression.

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.
