Web Interface for Image Processing
Wollný, Pavel ; Jošth, Radovan (referee) ; Beran, Vítězslav (advisor)
The bachelor's thesis treat of creation web interface for image processing. The basic demands for final application are defined here. Work is concerned with design client interface, server and their communication. After that implementation of these parts are described. System is based on technologies HTML, CSS, JavaScript, PHP and AJAX. Processing of photos is provided by GD library PHP and extern application, which is write with the help of library OpenCV.

Crowd-Sourcing Games for Annotations
Šujan, Tomáš ; Beran, Vítězslav (referee) ; Smrž, Pavel (advisor)
The goal of this bachelor thesis is to develop and implement a gaming application for the operating system Android, the purpose of which is to gather image annotations. The main purpose of this application is to simplify and improve this process, to extend the data range of these annotations and to provide entertainment for its users. The implementation of the application was processed in programming languages Android for the client segment and PHP for the server.

Protecting of image data
Nováček, Aleš ; Přinosil, Jiří (referee) ; Číka, Petr (advisor)
Bachelor´s thesis is about protection of digital images, especially about modern watermarking techniques. It consists of three main parts. The first one is the theoretical part, that describes watermarking terminology, techniques of embeding and detection of watermark, watermarking applications and watermarking requirements such as robustness and impercebility. The second and third part compares two methods of watermarking. Both methods are based on the transformation of image to the frequency domain. The first method uses discrete cosine transformation and the second one discrete wavelet transformation. Method using DCT embeds watermark by swaping DCT coefficients. The second method embeds watermark by modifying some coefficients of DWT decomposition according to the equation vi´= vi (1+sxi ), where vi´ is a coefficient of watermarked image, vi is a coefficient of original image, xi is pixel of watermark and s is scale factor, constant, that affects robustness of watermark.

High-Quality Visualization of Petri Nets for Publishing Purposes
Bednář, Drahoslav ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This work is trying to solve the problem of graphical visualization of Petri nets in text publications. The aim of the thesis is to create a tool that will simplify generating of Petri nets and at the same time provide a more aesthetic graphical output than existing tools do. A simplex algorithm was used for automatic network layout. The program has both graphical interface and text mode and can cooperate well with existing tools for working with Petri nets, which the text also mentions. The program is able to load a pnml file and produce a usable image in png, pdf, and svg formats.

MediaDiff - Diff for Static Images
Brothánek, Jan ; Mlích, Jozef (referee) ; Chmelař, Petr (advisor)
This bachelor's thesis focuses on comparison of digital documents, especially static images. This paper presents algorithms, which are usable for general data comparison and also specific algorithms major in image data comparison. We introduce possibilities of document comparison which are now available for users. On the basis of this current situation, a prototype of new modular application MediaDiff for various documents comparison is designed and implemented. We describe in detail each stage of the application development, problems which had arisen and their solutions. The possibilities of future development of the application are discussed.

Multiple Document Type Diff
Zemko, Michal ; Jirák, Ota (referee) ; Chmelař, Petr (advisor)
During the work on important projects, we have to backup current versions periodically. But sometimes we want to know what changes between two versions has been made. To recognize these changes, we can use the diff program that compares two text files line by line and can show differencies in various formats. A problem occurs, if we want to compare other than text files. The purpose of this bachelor thesis is to create one tool that can compare different types of files, for example images, Open Office files, DTP system LaTeX files, config files and, of course, standard text files. Each of listed types is specific and demands unique approach. This thesis deals with theoretical analysis of the problem and also with realization of the program which executes the comparision.

The Role of Visual Components in English Language Teaching Textbooks and in Teaching Methods from Diachronic Point of View
KUČEROVÁ, Alžběta
This thesis is concerned with visual components in English language teaching textbooks. The theoretical part presents basic types and functions of visual components and also deals with four language teaching methods, their development, principles that they are based on and techniques which are used during lessons. On the basis of findings from the theoretical part there are analysed four books. Each of them corresponds with one of the language teaching methods mentioned in the theoretical part. The analyses are supported with typical visual components from the textbook. The goal of this thesis is to evaluate to what extent is the typical usage of visual components from each method beneficial for teaching languages nowadays.

Choosen roles of photography in school mathematics at of "Group classes" Primary school
Urbánková, Šárka ; Kaslová, Michaela (advisor) ; Kvaszová, Milena (referee)
This thesis is pursued to the possibilities of using photography in teaching of mathematics. I have gathered enough information for condition of use photography. In the next step I made an analysis selected mathematics textbooks in terms of using photography according its six roles. Analysis has shown that most often use photos in textbooks is in a motivational role, that does not carry relevant information to solve a excercise. By the test I compared the influence of picture and photography on the correctness of solving excercises by pupils of the 2nd year of primary school. The test showed that a photography had a similar effect as a picture, and also it pointed out the need to looking for the right format, theme and quality of the photo. The next part of the thesis is devoted to the creation of excercises with photography in various roles for pupils of the 2nd year of primary school. Excercises include many different activities from manipulative to creative. Activities with phootgraphs is possible to use in different teaching organizations and can be used in teaching very quickly and easily. An important element is the emphasis on pupils' own creation, space for their representation of phenomena and joint evaluation of created photographs. Excercises can improve pupils' expression levels....

Choosen roles of photography in school mathematics at second grade of Primary school
Urbánková, Šárka ; Kaslová, Michaela (advisor) ; Kvaszová, Milena (referee)
This thesis is pursued to the possibilities of using photography in teaching of mathematics. I have gathered enough information for condition of use photography. In the next step I followed the objectives: to analyze selected mathematics textbooks in terms of using photography according its six roles; documenting the influence of photography in exercises on their answer; creating a task with photographs that would complement the gaps in their use in didactic materials. Analysis has shown that most often use photos in textbooks is in a motivational role, that does not carry relevant information to solve a excercise. The effectiveness of using a photo is verified on several excercises, which showed a higher abundance of right answers and pointed out the need to look for the right format, motive and quality of the photograph. This excercises also confirmed grasping a decimal system by pupils through a money model. The next part of the thesis is devoted to the creation of excercises with photography in various roles, which are less common in educational materials than the motivational role. Excercises include many different activities from manipulative to creative. Activities with phootgraphs is possible to use in different teaching organizations and can be used in teaching very quickly and easily. An...
