Extraction of Detailed Information from Palmprint
Folenta, Ján ; Sakin, Martin (referee) ; Kanich, Ondřej (advisor)
This master's thesis deals with obtaining information from palmprints. Its main goal is to extract information from the palmprint about the local orientation, frequency and width of the papillary lines, to detect principle lines and triradii and to track main lines, including the determination of the main line index. The result of this work is an application with a~graphical user interface, which, in addition to obtaining information from the palmprint, graphically displays this information, statistically processes it and enables its export. Testing and evaluation took place on a data set provided by the Department of Anthropology, Faculty of Science, Masaryk University in Brno, where detection of triradii achieved a success rate of 84.8 %, main line tracking reached success rate of 85.38 % and main line index determination reached success rate of 78 %.

Detection of Papillary Line Width by Fingerprints
Homola, Antonín ; Drahanský, Martin (referee) ; Lodrová, Dana (advisor)
This work outlines a method of detection of the papillary line width in fingerprints. This method is one of the possible methods of liveness detection. The first part of the work with deals defining of the fingerprint, attacks on today's systems and possibilities to improve security. The next section detection describes of the papillary line width. During the process of resolving, the first thing to do was to start operation of the scanning device and to read the database for tests and experiments. An independent application was created on this purpose. Further, there were projected methods for detection and measuring of the papillary line width. Use of the Canny edge detector with the Sobel operator and the Gaussian filter proved the best. Then, there is described implementation of individual methods. The next part of the work describes and assesses the results of the tests. The last chapter summarizes the work and proposes further possibilities of development.
