Implementation of Statistical Compression Method
Šreibr, Jakub ; Polok, Lukáš (referee) ; Bařina, David (advisor)
In this thesis statistical methods for data compression are presented. It deals with projecting of compression process and with it's implementation in a form of program library, which is created in language C++. Description and analysis of compression methods are discussed. The results of tests, which were performed with different compression methods are demonstrated.

Visualization of lossless compression algorithms
Madeja, Jiří ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This thesis focuses mainly on the development of visualization software for some of the most used lossless data compression algorithms. The first part of the thesis is devoted to the theoretical findings from the lossless data compression field. The second part of the thesis deals with the description of practical development of the software using Matlab. The draft is mainly focused on creating such environment to input data which will be encoded using most common lossless data compression algorithms, the comparison based on efficiency of those algorithms and visualization of the algorithm characteristics while in the process of encoding. Last part of the thesis is focused on presenting the final result of the software development.

Comparison of Lossy Image Compression Formats
Koláček, Ladislav ; Svoboda, Pavel (referee) ; Bařina, David (advisor)
This bachelor thesis deals with comparing of lossy image compression formats. The chapters describe principles of image compression and lossy formats themselves. Specifically the lossy formats JPEG, JPEG 2000, JPEG XR and WebP. The thesis includes theoretical comparison of the formats mentioned above, along with the methods used for measuring image quality. The practical part contains the results of the quality measurements of each format and description of design together with implementation of the tutorial.

Lossless Image Compression
Komjáthy, Gergely ; Polok, Lukáš (referee) ; Bařina, David (advisor)
This thesis deals with lossless image compression. In this paper are shown some colour models, which can be used for lossless image compression and formulas how to convert them to RGB and vica versa. You can learn predictors, how they work and discription of some of them. There is described the function of arithmetic coder, PPM coder and a brief description of Huffman coding.

Library of Compression Algorithms
Kozák, Filip ; Kaštil, Jan (referee) ; Košař, Vlastimil (advisor)
The purpose of this bachelor's thesis is to create the Library of Compression Algorithms which operates with data in memory. There is explained the principle of compression and decompression of individual methods, described steps and solutions for potential issues of individual algorithms and practical implementation of these algorithms. In conclusion there is the comparison of results of implemented algorithms with some existing programs for data compression.

Medical Image Data Compression
Balarin, Jakub ; Španěl, Michal (referee) ; Kršek, Přemysl (advisor)
The efficiency of various compress algorithms on medical images is explored in this paper. It try's to find algorithm or group of algorithms with the best compress efficiency. Except classic algorithms the medicine data properties (it contains many similar image points) can be used to reach higher compress level. We verify delta coding efficienty to final compress ratio. At the end the best founded method is presented.
