Temperature control and monitoring system
Mitter, Martin ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This work is dealing with the design for maintaining and monitoring optimal temperature for home-based data center. The purpose of this work is to prolong the life of hard drives in data center for as long as possible. First of all, the attention is given to establishing what the optimal temperature for maintaining long-live of hard drives is and how to correctly measure it. Based on the knowledge obtained from theory and from the prototype testing the final design of embedded system for maintaining this function is created.

Object detection
Baáš, Filip ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
This bachelor thesis deals with detection of rigid objects in images. Chamfer matching algorithm, which is built for this kind of tasks is used as detection algorithm. First part of this work is dedicated to theoretical explanation of the algorithm. Most commonly used metrics of distance transform are explained, which is needed for the algorithm. Also explanation of chamfer distance calculation and pyramid representation of information is here. Next part is dedicated to development tools used in this work, which is integrated development environment Visual Studio and libraries OpenCV for image processing and Qt for graphical user interface creation. In last part of this work, practical implementation of object detection is described. This part explains the way objects are rendered, steps for creating a template from rendered image, method to create set of templates, comparison of speed of distance transformation calculation in different metrics, comparison of speed of common and pyramid detection and method of score calculation. The conclusion summarizes reached goals of this work.

Digital device for supervising and evaluating outdoor activities
Pecen, Vojtěch ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This project deals with development of portable electronic device which brings new opportunities to leisure activities and their evaluating. At first, analysis of devices available on market and their acquisitions is made, then tips and ideas of new activities, which would be played with digital devices, summation of features, that the device would do, choosing adequate components, their assembly, configuration and programming. After it, domonstration of the device is described and this document is summarized.

Computer simulator for education
Friml, Dominik ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This bachelor thesis is divided into several parts. The first part consists of an introduction to individual parts of a processor and some of its peripheries. Next part of thesis is a research of existing educational and demonstrative tools usable in education. Results of the research were compiled into requirements for educational system. Using those requirements, and design of an architecture for educational processor for education, not only on FEEC BUT was created. As a next step, there is described a procedure, that led to a creation of a working simulator of the designed processor. Last part of this thesis is a design of several educational exercises, that demonstrates principles of computers and programming in a machine code and an assembly language.

Information system for network devices documentation
Kozlovský, Jiří ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This study is focused on creating and realisation of the concept of information system for network devices documentation at The Faculty of Electrical Engineering and Communication at Brno University of Technology. The aim of the study is to create system analysis, create process and data model, to solve the problematics of the documented entities lifecycles, solve problems of system access, including user roles. Then to implement the system, debug it and verify it's functionality.

Retargeting of the assembler language compiler
Navrátil, Jan ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This bachelor thesis describes a design and implementation of modification of retargetable compiler Flat Assembler G that provides a translation of assembly language for HCS08 microprocessor family. It describes current solutions in the design of assembly language compilers, existing retargetable compilers and their differences from Flat Assembler G. Furthermore, it shows process that can generate binary output in selected format with the compiler. Last part of this thesis is dedicated to testing of the correctness of the implementation and demonstration of the correctness on a real hardware.

Objects Classification in Images
Gabriel, Petr ; Petyovský, Petr (referee) ; Janáková, Ilona (advisor)
This master's thesis deal with problems of classification objects on the basis of atributes get from images. This thesis pertain to a branch of computer vision. Describe possible instruments of classification (e.g. neural networks, decision tree, etc.). Essential part is description objects by means of atributes. They are imputs to classifier. Practical part of this thesis deal with classification of object collection, which can be usually found at home (e.g. scissors, compact disc, sticky, etc.). Analyzed image is preprocessed , segmented by thresholding in HSV color map. Then defects caused by a segmentation are reconstructed by morfological operations. After are determined atribute values, which are imputs to classifier. Classifier has form of decision tree.

Image processing library wrapper for Lua
Prymus, Jiří ; Dusíková, Hana (referee) ; Petyovský, Petr (advisor)
The thesis deals with OpenCV library and its implementation into scripting language Lua. The first part of the thesis concentrates on description of the course Computer vision MPOV and description of mathematical basics needed for further understandings. The second part describes OpenCV library and its potential usage in the MPOV. Next chapter examines the programming scripting language Lua. The description of the implementation of binding the OpenCV library to Lua language along with its overall functionality is included in the practical part of the thesis. The use of LuaCV is more comfortable thanks to Open Source projects for cross-platform compilation and distribution. Part of the thesis is also generator of Latex documentation for LuaCV binding. The last chapter deals with testing LuaCV in course MPOV and analysis of criticism from students.

Automated optical measurement of drops contact angle
Dugáček, Ján ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
Measurement of surface tension of solids usually requires manual processing of photographs of droplets of liquids with known properties on the measured material's surface, during which the contact angle is manually determined. The objective of this work is to implement an algorithm that can determine these contact angles from photographs and does not require the photographs to be made under specific light conditions. The implementation cannot depend on paid libraries and must be simple to incorporate into existing software.

Optimal Deployment of Multiple Hypotheses Generators for Detecting Traffic Lights in Camera Images
Bajus, Tomáš ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
Táto práca sa zaoberá detekciou semafórov na snímkoch z kamery. Cieľom je nájsť vhodné nastavenie a kombináciu dostupných detektorov. V prvej časti práce je vysvetlený princíp funkcie použitých detektorov. Nasleduje zhodnotenie vlastností jednotlivých detektorov pred ich optimalizáciou. V ďalšej časti práce je popísaný proces testovania a evaluácie detektorov a predstavený nový systém pre zefektívnenie hľadania optimálneho nastavenia detektorov. V rámci optimizácie je popísaný effekt jednotlivých parametrov na chovanie systému a sú navrhnuté rozpätia vhodných hodnôt pre každý parameter. Taktiež je predstavené nové zapojenie detektorov sú nájdené optimálne pracovné body systému. Posledná časť sa zaoberá použitím vhodných metód na filtorvanie a zhlukovanie hypotéz. Nakoniec je prezentovaná celková funkčnosť systému pred a po optimizácii a výsledky sú zhodnotené.
