Anti-Drone Perimeter Protection
Janík, Roman ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
Developement of drone technology brings opportunities for many fields of human activity, but simultaneously brings security threats. A need to effectively face these threats arises. In this work, problematics and state-of-the-art methods for object detection in a video captured by moving camera. Further I proposed a system for a drone or a flock of drones detection and localization. Algorithm for detection is based on convolutional neural network, specifically on SSD algorithm. I implemented the system with library OpenCV with possible acceleration of algorithm with GPU via OpenCL. I tested the created solution on both a video and a video camera output.

Acquisition and Recognition of 3D Signature
Molitoris, Miloš ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
This work deals with methods of signing in 3D space, selecting a suitable scan model, obtaining a sufficient number of samples to create a database, and finally verifying signatures. The first part deals with the issue of existing solutions and methods of signature verification, further image processing required for marker shooting in 3D space. The following sections are dedicated to design a unique signature solution in free space using a pen without any contact. Two shooting models have been designed using cameras or Leap Motion sensor. The application was implemented based on DTW algorithm using this sensor resulting in a dynamic signature verification system. Furthermore, the work includes a description using of database creation and experimental signature verification. At the end, we find an assessment of the security and error rate of the system that is compared to other methods. The result of this thesis is an application for 3D signature capture and recognition with the potential of a new technique for secure signature.

Diagnostics unit for train protection system
Dvořák, Michal ; Žilka, Martin (referee) ; Tomíček, Pavel (advisor)
Aim of this work is to design electronic device capable of transfering and saving sent data from a comunication bus. First was introduced importance of such device in context of interstate rail travel. Next, the work introduces all the necessary norms, which must the device in question comply with, and how such norms affecting the design itself. This is followed by introduction of used communication protocols and buses and their implementation. Next, reader is introduced to design of the schematic and design considerations for PCB design. In the last chapter the data rate performance of the modul is evaluated.

Detection, Extraction and Measurement of the Length and Width of the Metacarpal Bones in Images
Paul, Daniel ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
Ľudské telo bolo po celé storočia bodom mnohých štúdií. Chceme zistiť všetko, čo je možné sa o nás dozvedieť, o tom, ako fungujeme a prečo tak fungujeme. Vedci nám poskytujú výskumy, ktoré objasňujú tieto otázky. Mali by sme byť súčasťou tohto výskumu a obohatiť naše vedomosti prispievaním do vedy. Preto bude táto práca zameraná na detekciu, extrakciu a meranie metakarpálnych kostí na obrázkoch. Táto práca poskytne čitateľovi vedomosti o určitých metódach spracovania obrazu a záprstných kostiach. Predstaví proces extrakcie ich kontúr a ukáže spôsob, ako merať ich šírku a výšku.

Possibilities of using computer Raspberry Pi in teaching at elementary school.
DVOŘÁK, Michal
This Bachelor thesis deals with testing of the performance, abilities and possibilities of a minicomputer Raspberry Pi 4 model B for it's utilization in primary school edu-cation. Raspberry Pi 4 model B is a minicomputer from British charity organization Raspberry Pi Foundation which made it as a teaching support for informatics classes at schools. In the theoretical part of this thesis, topics as personal computer, operating systems and computer hardware are elaborated on. The practical part deals with tes-ting the minicomputer itself, it's process and the results. It also includes sample in-structions and applications that could be appropriate for inclusion to the primary school education. In the conclusion of the thesis, I elaborated on the evaluation of the possibilities of the minicomputer Raspberry Pi 4 model B in primary school edu-cation and on the contrary, for which purposes it is not suitable.

The influence of employment policy measures on employing persons with disability
Dvořák, Michal ; Tomeš, Igor (advisor) ; Hutař, Jan (referee)
The object of the thesis - The influence of employment policy measures on employing persons with disabilites - is set of employment policy measures applying to emplyoing persons with disabilites in the Czech Republic, and the influence of the measures on employing such persons from 1997 through 2007. The thesis describes development of the measures, analyses the measures costs, and considers the measures influence on the progress of the unemployment rate among persons with disabilites.
