Creating programs for teaching signal and image processing
Novotný, Luděk ; Číž, Radim (referee) ; Rajmic, Pavel (advisor)
The bachelor thesis deals with the problém of creating interactive JAVA applets. The practical part of work consist of desing, development and debugging four applets. The first one clearly explains the issue of phasor theory, the second one shows frequency filtering of audio signals, the third one demonstrates artificial coloring of grayscale images and the fourth one creates Huffman code from input text. The theoretical part describes the JAVA language, advantages of applets and theory, which relates to particular applets.

Multimedia player controlled by hand gestures.
Novotný, Luděk ; Přinosil, Jiří (referee) ; Olejár, Adam (advisor)
This diploma thesis deals with the hand gesture detector. Theoretical part is devoted to the discussion of current segmentation and detection methods. They were chosen those, which would work best as the controlling methods of multimedia player. The proposed algorithm is described with the help of flowcharts. Detector is written in Java language with the use of OpenCV library. Background subtraction segmentation method and convex hull approximation are used for gesture detection. Detector can distinguish between six gestures and track the center of palm. Finally, the detector was connected with proposed and implemented document, image and multimeda files browser.
