Search for Duplicities and Quality Evaluvation of Photos
Sklenář, Zdeněk ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
This bachelor thesis is about the analysis, design, and implementation and testing of an application, which is used to find duplicates in photographs according to it's Exif metadata. The app can also let you preview the photo, including Exif metadatas. It is possible to filter your photos. You can group duplicates with the original photo, and select the best photos to keep it in accordance with a user-defined parameter, then manually adjust this option, and deleting others. There is also a possibility to export selected photos to a ZIP archive.

Machine learning models for quantifying phenotypic signatures of cancer cells based on transcriptomic and epigenomic data
Koban, Martin ; PhD, Florian Halbritter, (referee) ; Mehnen, Lars (advisor)
S rozvojom techník pre efektívnu akvizíciu genomických dát sa jednou z kľúčových vedeckých výziev stala interpretácia výsledkov týchto experimentov v zmysluplnom biologickom kontexte. Táto práca sa zameriava na využitie informácií ukrytých v dobre charakterizovaných transkriptomických a epigenomických dátach z verejne dostupných zdrojov pre účely takejto interpretácie. Najskôr je vytvorený integrovaný súbor dát generovaných metódami DNase-seq a ATAC-seq, ktoré kvantifikujú chromatínovú dostupnosť. Tieto údaje sú doplnené verejne dostupnými výsledkami techniky RNA-seq pre kvantitatívne hodnotenie génovej expresie a vhodne predspracované pre ďalšiu analýzu. Pripravené dáta sú následne použité na trénovanie modelov strojového učenia (klasifikátorov) s dvomi základnými cieľmi. Po prvé za účelom augmentácie metadát prislúchajúcich k jednotlivým biologickým vzorkám v trénovacom dátovom súbore pomocou predikcie nedefinovaných anotácií. Po druhé pre anotáciu zle charakterizovaných testovacích dát (nepoužitých v trénovacej fáze) za účelom overenia generalizačnej schopnosti zostavených modelov. Dosiahnuté výsledky ukazujú, že natrénované klasifikátory sú schopné zachytiť biologicky relevantné informácie, zatiaľ čo vplyv technických artefaktov je minimalizovaný. Navrhnutý prístup je preto schopný prispieť k lepšiemu pochopeniu komplexných transkriptomických a epigenomických dát, predovšetkým v oblasti onkologického výskumu.

Usability Improvement of Geovisto Library
Koscielniak, Tomáš ; Rusňák, Vít (referee) ; Hynek, Jiří (advisor)
This thesis aims to improve the user interface of Geovisto library, used for geospatial visualization. This is achieved by identifying issues using user testing and designing a solution for them. These solutions were implemented, and the second user testing tested their benefit. The result of the thesis is expanding the library with legends, units for numerical values, and tools for visualization of metadata, which all improve the user experience when using the library. Another result is a standalone web presentation of the library, its tools, and data miner.

Semantic Annotation of the OpenDocument Format
Nakládal, Jan ; Šperka, Svatopluk (referee) ; Schmidt, Marek (advisor)
This work is about analysis, design and implementation of application as an extension to office suite OpenOffice.org. This application allows users to view metadata RDF format found in text content and editing By using this functionality, we can see specific information about people, places or objects mentioned in the document and paste it directly into the document itself. Practical we can use this for more details information about the person used in text.

Extended Manipulation of Music File Playlists and Metadata in GMPC
Adamec, Jakub ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
The aim of the bachelor thesis is to design and supplement a client application for the music server Music Player Daemon (MPD), which allows editing local music files and downloading data from internet services. Along with provide extraordinary operations with playlists and extracts tempos from songs. Before solution of application, we can find theoretical analysis, which includes a description of metadata, music data formats and an analysis of MPD and GMPC. In the last chapters of the work is a description of the application solution ending with the evaluation of the results.

The API of a Video and Image Datastore
Fröml, Vojtěch ; Volf, Tomáš (referee) ; Zendulka, Jaroslav (advisor)
This master's thesis proposes and implements an extension of the database interface VTApi which is being developed as a part of the MV ČR project "Tools and methods for video and image processing for terrorism prevention" at FIT VUT. This interface provides support for representation, management and indexation of multimedia data and related descriptive metadata used by analytic applications based on computer vision. It currently uses DBMS PostgreSQL as its default datastore. Paper describes basic techniques for processing image and video data, VTApi concept and proposes and implements its modifications for the purpose of supporting multiple types of datastores. As an example of an alternative datastore, support for usage of a SQLite database is integrated into VTApi.

Multimedia Browser for Lectures
Kubalík, Jakub ; Potúček, Igor (referee) ; Schwarz, Petr (advisor)
In preamble reader will understand the purpose of this project and why it was initiated. It's large team project, so description of its structure represents main part of this report. A core of the browser contain a lot of techniques, e.g. system of components, special internal communication and other. The main goals of this system are portability and reusability - there is exact specification of syntax rules and used data formats. Non-interchangeable role in project has format XML. Invention of new components was the last intervention in project, with intention to use of the project in future and involve in complex search engine - the engine discuss final part of report.

Detection of Groups and Duplicities of Photos
Václavík, Vojtěch ; Kolář, Martin (referee) ; Zemčík, Pavel (advisor)
The bachelor's thesis aims to create an application that allows import of photographs and to sort duplicities. The application simplifies the import by showing already imported photographs and also hiding the not necessary ones. The application can also be used for finding duplicities or comparing folders, helping the user to clean their photo gallery. Other than that, it is also possible to show photographs with similar timestamps. To identify duplicates the application uses EXIF metadata included in photographs. The application was implemented in C++, graphical interface in Qt framework, work with metadata mediates EasyEXIF library and the database communication uses SQLite library.
