Computation of the eigenvalues and eigenvectors of Hermitian matrix
Štrympl, Martin ; Bohrn, Marek (referee) ; Fujcik, Lukáš (advisor)
This project deals with computation of eigenvalues and eigenvectors of Hermitian positive-semidefinite complex square matrix of order 4. The target is an implementation of computation in language VHDL to field-programmable gate array of type Xilinx Zynq-7000. This master project deals with algorithms used for computation of eigenvalues and eigenvectors of positive-semidefinite symmetric real square and positive-semidefinite complex Hermitian matrix and the analysis of algorithms by AnalyzeAlgorithm program assembled for this purpose. The closing part of this project describes implementation of the computation into field-programmable gate array with use of IP core Xilinx® Floating-Point \linebreak Operator and SVAOptimalizer, SVAInterpreter and SVAToDSPCompiler programs.

Watermarking as Document Protection
Segedy, Patrik ; Kočí, Radek (referee) ; Hanáček, Petr (advisor)
This thesis is dealing with document protection using a digital watermarking. First, a watermark characteristics are presented. Then, different usages of the watermarking are discussed. Next part of the thesis is dedicated to current development in watermarking field. It is aimed at various principles of watermark embedding into different multimedia types. Subsequently, a watermarking scheme for still images is proposed and implemented. Finally, the watermarking scheme undergoes attacks, which should damage embedded watermark. Attacked watermark is then extracted and compared to the embedded watermark.

Multipoint identification of position and orientation of object
Řičánek, Dominik ; Ligocki, Adam (referee) ; Burian, František (advisor)
The goal of this paper is to find a good method to determine the pose of two, mutually rotated, objects and to try and implement it first in C++ without the usage of any external libraries and then in Kuka Robot Language (KRL). First we are going to look at two different approaches to solving this problem: The Iterative Closest Point algorithm (ICP) and the Kabsch Algorithm. From them one is going to be chosen and a program will be build around it. Following its implementation, the algorithm’s precision is going to be tested. Finally KRL will be briefly introduced and the various problems involving transition of the algorithm from C++ to KRL will be talked about.
