Barcode recognition system
Pribula, Wojciech ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
This thesis describes barcodes which are used in postal services. Specifically, it is concerned with Intelligent Mail Barcode, the GS1-128 code, the C128 code of Ceska posta (Czech Postal Services) and the QR code. The thesis attempts to analyze methods of encoding information into barcodes and error detection algorithms used for error correction during the decoding processes. Most importantly, there is described Reed-Solomon error correction in the QR code. There are presented and evaluated different methods of code detecting which are suggested by authors of various academic articles. The thesis also describes the method of creating test sets of images and proposed appearances of the scanning scene. Additionally, there are described algorithms for detection and decoding barcodes GS1-128, C128 and IMB in the image which was created during the work on this thesis. Finally, there is the evaluation of the percentage success of algorithms.

The Impacts of Maritime Piracy on International Trade
Mühl, Adam ; Černá, Iveta (advisor) ; Čajka, Radek (referee)
The diploma thesis analyzes the impacts of maritime piracy on international community. The study analyzes the situation in terms of economic impacts, but also in terms of international cooperation in solving piracy issues. The aim of the diploma thesis is to define most vulnerable locations, quantify economic impacts and evaluate the impacts of military missions in the affected regions, as well as analyze the published recommendations.
