Prague Dependency Treebank as a Czech grammar practice book Prague Dependency Treebank as an exercise book of Czech
Kučera, Ondřej ; Vidová Hladká, Barbora (advisor) ; Panevová, Jarmila (referee)
Prague Dependency Treebank (PDT) is one of the top language corpora in the world. The aim of this work is to introduce a software system that builds an exercise book of Czech using the data of PDT. Two kinds of exercises are provided: morphology (selecting correct parts of speech and their morphological cathegories) and sentence parsing (selecting analytical functions and dependencies between them). The PDT data cannot be used directly though, because of the differences between the academic approach in sentence parsing and the approach that is used in schools. Some of the sentences have to be discarded completely, several transformations have to be applied to the others in order to convert the original representation to the form to which the students are used to from school.

Input audio preamplifier used for laboratory measurements
Kučera, Ondřej ; Kaller, Ondřej (referee) ; Kratochvíl, Tomáš (advisor)
This article looks at pre-input low-frequency amplifiers for laboratory work. The task was to study, design and build a fully functional pre-input amplifier for use in low frequency audio technology. In each section, we will discuss the various preamps, which are classified according to signal processing parameters. The construction of each amplifier uses discrete components and operational amplifiers. The second part of the article looks at different measuring devices, such as input sensitivity, transfer characteristics and input impedance etc., which would form part of the amplifier.

Library for Evaluation of Noises Used in Procedural Texturing
Kučera, Ondřej ; Chudý, Peter (referee) ; Herout, Adam (advisor)
The aim of the work is to describe procedural texturing and usage of a noise for creating textures of real materials. The reader will learn the fundamentals of the noise, its properties and a way of using it. Random numbers and interpolation methods are important parts of the noise evaluations, therefore there are chapters about random numbers generating and interpolation methods. Obviously, there is not missing the chapter, which is depicting properties and principles of several methods of creating noise. The main part of this work is effective implementation of library with a chosen noise methods, so next chapters are about choosing methods and design of the interface, implementation and many kinds of tests and optimalizations. Achieved results and final conclusions are at the end of this work.

Colour image histogram processing
Kučera, Ondřej ; Číka, Petr (referee) ; Říha, Kamil (advisor)
This bachelor thesis deals with processing of colour image histogram. To better undestanding of this problem it describes individual methods which edit colour image and its histogram. The thesis suggests a program implementation which allows processing of colour image and its histogram.

New methods for super-resolution imaging
Kučera, Ondřej ; Rajmic, Pavel (referee) ; Špiřík, Jan (advisor)
This master's thesis deals with methods of increasing the image resolution. It contens as a description of theoretical principles and description of calculations which are wellknown nowdays and are usually used for increasing image resolution both description of new methods which are used in this area of image procesing. It also contens a method which I suggested myself. There is also a description of methods for an evaluation of image similarity and a comparation of results from methods which are described in this thesis. This thesis includes implementations of selected methods in programming language MATLAB. It was created an application, which realizes some methods of increasing image and evaluate their results relation to the original image using PSNR and SSIM index.
