Implementation of Statistical Compression Methods
Ftorek, Peter ; Polok, Lukáš (referee) ; Bařina, David (advisor)
The aim of this thesis is to describe statistical methods for data compression. Introduction covers theoretical minimum of data compression. Center of the work is about description of each method and implementation of Burrows-Wheeler compression algorithm in C programming language. It contains test results of each method and their evaluation.

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.

Medical Image Data Compression
Šebek, Jiří ; Bařina, David (referee) ; Kršek, Přemysl (advisor)
This thesis deals with several lossless methods of image compression. The main goal is to achieve the best compression ratio for set of medical images. This paper provides brief introduction into the data compression theory. It also contains design of image compression and description of designed compression modules implementation. Also the verifi cation of suitability of designed method for medical images compression is involved.

Implementation of Statistical Compression Methods
Beněk, Tomáš ; Polok, Lukáš (referee) ; Bařina, David (advisor)
This thesis deals with the statistical compression methods. This work describes basic theoretical introduction to the data compression and the most important representatives of statistical methods. There is also described compression process based on the Burrows-Wheeler algorithm, which is implemented in the form of portable library in C++ programming language. This work compares effectiveness of each method on suitable data corpus, which contains various data types and according to achieved results discusses suitability of usage of methods and possible improvements.

Personal expirience of transsexuals with the process of gender transformation
Angelisová, Aneta ; Goldmann, Petr (advisor) ; Adámková, Jana (referee)
The diploma thesis deals with the issue of gender identity disorders, specifically transsexualism. The theoretical part defines the basic concepts that are essential for understanding the whole issue and which are used throughout the thesis. It includes a total of five chapters to the topic of transsexuality in terms of psychology and legislation. The first chapter briefly defines the term transsexuality from the perspective of various experts and professional publications, it is devoted to the history and etiology of transsexuality. The second chapter discusses gender identity and factors that may influence the development of identity. The third chapter deals with the process of gender transformation in transsexual subjects from the very beginning of treatment to its termination. The fourth chapter deals with partnership, sexuality and adaptation of transsexual individuals. The fifth chapter looks at transsexuality from the legislative point of view, defines the laws that deal with the issue of transsexualism. The empirical part is devoted to the realized research focused on own experience with coming out, process of gender transformation, environment reactions and partnership relations. The research is of a qualitative nature; it was conducted through semi-structured interviews with 8 of the 16...
