Editor for WSQ Format of Fingerprint Images for Demonstration
Németh, Patrik ; Rydlo, Štěpán (referee) ; Kanich, Ondřej (advisor)
The goal of this thesis is to design and implement an application suitable for demonstrating the individual steps of fingerprint analysis, and which is able to automatically process fingerprints stored in the most widely used formats for storing fingerprint imagery, such as WSQ, PNG and JPEG 2000. In this thesis special attention was given to automatic processing methods and analysis of fingerprint imagery. It also offers an overview of the WSQ format and of its comparison to JPEG 2000. The output of this work is a graphical application capable of demonstrating individual steps of widely used methods of fingerprint imagery processing and analysis. The application implements Gabor filtering, line thinning based on the Zhang-Suen method, and other methods of fingerprint processing. With some error, it is capable of detecting minutiae, singularities and the class of a fingerprint. Some of the processing parameters may be modified by the user via the graphical interface. Processed images can be exported in various image formats.

ECG Data Compression
Németh, Patrik ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
This work tackles the subject of ECG data compression on microcontrollers. First, the physiology of the heart and recording of the heart’s activity is explored. Then the work provides an overview on various compression methods with a focus on their usability on systems with limitied computing power and memory. This work also outlines the architecture and instruction set of ARM processors and then proposes and implements a compression algorithm based on existing research. A Python prototype and a C implementation for microcontrollers are both evaluated and the results are then discussed.
