Speech activity detector in digital signal processor
 Kovařík, Jiří ; Mach, Václav (referee) ; Sysel, Petr (advisor)
In this diploma thesis were created voice activity detectors according to the standard ITU-T G.729 and G.723.1. The voice activity detectors were implements in the digital signal processor TMS320C6416 made by Texas Instruments. At the same time detectors were designed using by MATLAB programming language. The diploma thesis can be divided into two parts. In the theoretical section provides information on how to report detectors in the standard ITU-T G.729 and G.723.1. In the implementation part is described steps in the implementation of the detector in signal processor TMS320C6416 and there are discussed various differences compared to the documentation.

Toolbox for automatic EEG data quality assessment
 Meloun, Jan ; Gajdoš, Martin (referee) ; Lamoš, Martin (advisor)
This thesis deals with designing a tool for automatically evaluating the quality of electroencephalographic data. In the theoretical part of the thesis, there is a theoretical basis in the anatomy of the central nervous system and the brain, followed by a description of the origin and propagation of the action potential through the nervous system. Furthermore, the theoretical part of the work is devoted to electroencephalography (EEG) and the description of the EEG recording, including typical artefacts in it. The following describes the methods used to detect and remove artefacts. These are primary methods for extracting data quality features. The practical part of the thesis contains a description of the design of a tool for automatic EEG quality assessment and its testing on artificial and real data. The last part of the work is devoted to the discussion of the results of the success of the detection of channels or sections with artefacts and the possible further extension of the tool.
