Path Planning in 3D Space
Sasýn, Radek ; Zbořil, František (referee) ; Rozman, Jaroslav (advisor)
This work describes path finding among obstacles in 3D space using probabilistic algorithms. Users can create scene in application GUI - define start object, obstacles, goal position and run probabilistic algorithm. The finding path is visualized. The work describes probabilistic algorithm, collision detection and the basics of 3D graphics and shows design and implementation of an application created.

Robot Programming Framework in Virtual Environment
Maťátko, Martin ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This diploma thesis deals with a theoretical analysis, a design and an implementation of a programming framework in a virtual environment. Robots use sensors to gain information about the environment and they subsequently modify this environment as a result of an instruction code. The instructions are entered in a graphic form using a visual programming language. The analysis and the outline of this language is discussed in detail in this work as well. The last part describes editing and rendering of the virtual world in which the robots are moving, considering sample tasks of following a line and movement inside a maze according to the rules of the Micromouse competition. The thesis includes solution proposals for both tasks regarding the possibilities of the programming environment. The result of the work is a concept of the aforementioned components and their implementation and linking to a functional unit.

CAPTCHA Recognition
Klika, Jan ; Samek, Jan (referee) ; Rozman, Jaroslav (advisor)
This thesis describes the design and implementation of an application for breaking the CAPTCHA. It also describes the history and evolution of CAPTCHA and the ways of its generating and possible techniques of its breaking. This thesis focuses on the new types of CAPTCHA, based on hard character segmentation. So the main target of this thesis is the design and implementation of the new segmentation method, allowing the recognition of modern CAPTCHAs, especially reCAPTCHA.

Real-time text translation with using mobile devices
Sztefek, Lukáš ; Rozman, Jaroslav (referee) ; Samek, Jan (advisor)
The aim of this thesis is design and implementation of Android application which will serve as real-time translator from one language to another, including several world languages and Czech. The text obtained from image is translated and replaces the original one with keeping its visual look as much as possible. The reader gradually gets familiar with getting text from images, text translation, displaying text on mobile device and Android OS implementation. In conclusion, the experiments with multiple input images and comparison of existings applications have been done.

The Betting Agent
Bělohlávek, Jiří ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This master thesis deals with design and implementation of betting agent. It covers issues such as theoretical background of an online betting, probability and statistics. In its first part it is focused on data mining and explains the principle of knowledge mining form data warehouses and certain methods suitable for different types of tasks. Second, it is concerned with neural networks and algorithm of back-propagation. All the findings are demonstrated on and supported by graphs and histograms of data analysis, made via SAS Enterprise Miner program. In conclusion, the thesis summarizes all the results and offers specific methods of extension of the agent.

Support of Learning the Lithuanian
Kunetka, Martin ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This thesis analyzes the requirements imposed on applications for teaching foreign languages and proposes a structure and functions of a program fulfilling these requirements in a specific case of Lithuanian language. The proposal is afterwards implemented and evaluated in the respect of meeting the objectives.

Application for Processing of a Photographed Text
Genčúr, Martin ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This work introduces main approches for converting a photographed text into black and white form. It analyses particular methods being used for this task. Following part describes implementation of the application performing a conversion. The program is tested with suitable data (coloured picture, a picture with various shades etc.) and illustrates the usability of the application. The thesis also contains an introduction to optical character recognition (OCR) and suggests potential ways of development of this application.

Alignment of DNA Parts
Pejř, Václav ; Burgetová, Ivana (referee) ; Rozman, Jaroslav (advisor)
This thesis deals with finding the possibilities within the sphere of alignment of DNA sequences. Based on these findings, the best solution should be found with regard to the quickness of computation and quality of alignment. Following this I intend to implement and thus create a functioning program that will do the alignment. The thesis starts with introducing issues dealing with biology, DNA and genetics. The introduction is followed by a survey of algorithms that are used for alignment, their evaluation and selection of the most appropriate algorithm for the implementation. The thesis also focuses on the usage of parallel programming by means of OpenCL libraries. The alignment is being done above many sequences at the same time, so that the methods how this process can be done and how to reach the best results are being examined.
