Techniques for movement detection and prediction in video sequences
Nešpor, Zdeněk ; Říha, Kamil (referee) ; Číka, Petr (advisor)
This bachelor thesis deals with techniques for motion detection and prediction in digital images. After an initial consideration over the need of digital video compression a basic concepts of digital video is introduced. The MPEG-1 video compression standard and using of motion detection and prediction inside the compression technique is described in the next part. The following part describes motion estimation methods. The most widely used motion estimation methods, block matching methods, are described in detail together with proposed improvements. The second part of this paper concentrates on a developed application in C++ language that demonstrates performance of described motion estimation techniques on slow, medium and fast motion. The results of testing and suitable method for each motion type is in the end of this work.

Vefication of Metadata for Sound Recordings
Přerovský, Petr ; Bartoň, Radek (referee) ; Láník, Aleš (advisor)
The work deals with verification of the metadata of audio recordings in an environment of mobile phones running Android. The text work is divided into three main parts. The first part is focused more on theoretical basis, where the main emphasis on the description of Android, application structure, description of the audio MP3 file and theoretical basis of Fourier transform in signal processing. The second part is devoted to solution design, analysis and implementation. The third part deals with testing.
