Multimedia Diff - Audio Documents
Komadel, Michal ; Dittrich, Petr (referee) ; Chmelař, Petr (advisor)
This work describes development of a diff tool working with audio files containing general sound such as music, speech and other sounds. There are presented facts from different domains of science related to sound, such as psychoacoustics, speech recognition and automatic music genre categorisation. This paper also contains description of some diff algorithms and external tools needed for development of the goal application. Moreover, there is introduced design and implementation of the application, settings used for sound features extraction and evaluation of attained results.

Multiple Type Office Documents Diff
Varga, Tomáš ; Volf, Tomáš (referee) ; Chmelař, Petr (advisor)
This bachelor thesis deals with comparing different types of office documents. The aim of this thesis is to create a module into an existing application called mediadiff for comparing documents of the Open Office office suite, including text documents, presentations and spreadsheets. This thesis describes algorithms for comparing text and tree structures. Furthermore, there are described the best known office suites and Access to the content of their documents.

Multimedia Document Type Diff
Lang, Jozef ; Hlosta, Martin (referee) ; Chmelař, Petr (advisor)
Development of Internet and its massive spread resulted in increased volume of multimedia data. The increase in the amount of multimedia data raises the need for efficient similarity detection between multimedia files for the purpose of preventing and detecting violations of copyright licenses or for detection of similar or duplicate files. This thesis discusses the current options in the field of the content-based image and video comparison and focuses on the feature extraction techniques, distance metrics, design and implementation of the mediaDiff application module for the content-based comparison of video files.

Multiple Document Type Diff
Zemko, Michal ; Mlích, Jozef (referee) ; Chmelař, Petr (advisor)
This thesis deals with comparing different types of files, especially source codes. It describes the problem of comparing source code and different ways of solving this problem, from simple line comparison, to AST comparison. Chosen method was comparison based on lexical analysis. This is also described in the work with instruments of its automation. The goal of this thesis is to design and implement modular application, which compares different types of files. The implemented module compares source code in programming languages C/C++, Java a Python. This module is easily extendable for comparisons with other languages.

Analog IO simulator
Maslák, Petr ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This bachelor’s thesis deals with measuring device USB 6008. This thesis describes at the beginning properties of measuring device like count of channel, speed, accuraccy. Next chapter concerns with programming environment like MS Visual C++, CVI and LabView. The most suitable programming environment was chosen Labview. The result of this thesis is programm that can read and write analog samples, display signals in Chart, simulate first order dynamic system.

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.

A backup system
Setnička, Jiří ; Mareš, Martin (advisor) ; Veselý, Pavel (referee)
An overview of existing approaches to data backup and their strengths with regard to use. After considering the previous describe the resulting backup system FenixBackup as file-oriented differential backup system capable holding more historical versions. In conclusion, outlines the possible directions which the development of the system could follow. Powered by TCPDF (www.tcpdf.org)
