Scripting in Audacity Audio Editor
Šípoš, Peter ; Pop, Tomáš (advisor) ; Jančík, Pavel (referee)
Audacity is popular and widely used audio editor available for all the main platforms including Windows, Mac as well as various Linux distributions. Audacity functionality can be controlled via sophisticated user interface, but the editor suffers from a lack of support for an automated execution of scripts and therefore, using audacity e.g., to perform the same action on multiple files can be tedious. The thesis aims at extending Audacity editor to allow using scripts in the audio editing workflow. The first part of the thesis overviews Audacity's architecture, and discuss, how Audacity can be extended and what alternative applications are available. Then, the thesis describes the most important decisions that were taken, including the choice of scripting language, managing errors and designing user interface. Finally, the extension functionality is shown on several examples reflecting a typical use-cases.

Application for automatic recognition of textures in map data
Šípoš, Peter ; Skopal, Tomáš (advisor) ; Lokoč, Jakub (referee)
This work has aimed to implement an easy-to-use application which can be used to navigate through aerial imagery, assign sections of this image for different classes. Based on these category assignments the application can autonomously assign categories to so-far unknown fields, hence it helps the user in further classification. The output of the application is an index file, which can serve as underlying dataset for further analysis of a given area from geographic or economic point-of-view. To fulfil this task the program uses standard MPEG-7 descriptors to perform the feature extraction upon which the classification relies.
