Interactive web applications for support of teaching signal processing
Mašek, Petr ; Rajmic, Pavel (referee) ; Záviška, Pavel (advisor)
The bachelor thesis deals with the topic of processing one-dimensional signals. Five interactive web applications have been created in JavaScript to support teaching. These are applets that relate to the following topics: rational number resampling of the discrete signal, mean and root mean square signal values, discrete linear and circular convolution in 1D, and discrete cross correlation. The thesis introduces each topic by a theoretical foreword, followed by description of implementation and user interface of the created applications and further there is a commentary on the development and testing of applets.

Interactive web applications for teaching purposes in the field of signal processing
Kuba, Michael ; Rajmic, Pavel (referee) ; Záviška, Pavel (advisor)
This thesis deals with selected topics of signal processing. The aim of the project is the implementation of four interactive web applications in JavaScript, intended for teaching purposes. These applications deal with following topics: rational number resampling of the discrete signal, mean and root mean square signal values, discrete linear and circular convolution in 1D, and discrete cross-correlation. The thesis is divided into the theoretical and the practical part. There is a theroretical foreword of topics the applications deal with, including an introduction to signals followed by a description of functionality and the user interface of created applications.

Acoustic Detection of Speaker Position Using Microphone Array
Pelz, Zdeněk ; Novotný, Ondřej (referee) ; Szőke, Igor (advisor)
This thesis explores problematics of speaker localization using microphone array. Aim of this thesis is implementation of algorithms for speaker localization and experiments with those algorithms. Calculation of TDOA was done using cross-correlation and hyperbolic method was used to calculate position estimation. Finished microphone array is able to locate speaker within certain variance. Results of this thesis allow reader to make assumptions regarding accuracy of localisation using microphone array and ARM kit with limited performance. Precision of position estimation using microphone array reached several decimeters, but this precision is dependent on distance from microphone array.

Small-Size Microphone Array for Estimation of Direction of Arrival of Sound
Kubišta, Ladislav ; Honzík, Petr (referee) ; Schimmel, Jiří (advisor)
This thesis describe detection of direction receiving sound with small–size microphone array. Work is based on analyzing methods of time delay estimation, energy decay or phase difference signal. Work focus mainly on finding of angle of arrival in small time difference. Results of measuring, as programming sound, so sound recorded in laboratory conditions and real enviroment, are mentioned in conclusion. All calculations were done by platform Matlab

Interactive software tools for teaching signal processing
Pacas, Ondrej ; Rajmic, Pavel (referee) ; Mangová, Marie (advisor)
This thesis deals with creation of four interactive applications for educational purposes in the field of digital signal processing. The goal of this work is to create four applications which will visually interpretate each of the methods of signal processing. This involves applications for linear regression and least squares method, interpolation and signal reconstruction from its samples, discrete linear convolution and discrete cross-correlation. Applications are created using JavaScript programming language.

Evaluation of Target Shooting by Computer Vision
Gregorová, Jana ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
Cílem této práce je aplikace, která bude v reálném čase automaticky vyhodnocovat skóre střelby na terč ze střelné palné zbraně pomocí kamery připojené k počítači. Střelec tak bude mít možnost sledovat výsledky střelby přímo ze střeleckého stanoviště i během střelby. Výsledná aplikace zpracovává vizuální data z kamery, která sleduje terč. Terč a plochy na tomto terči s různým skóre jsou detekovány automaticky. Obraz z kamery je stabilizován pomocí křížové korelace a nové zásahy jsou detekovány v masce popředí. Výsledkem této práce je aplikace, která zefektivňuje trénink sportovní střelby.

High precision sub-pixel image registration methods and their applications in astrophysics
Hrazdíra, Zdeněk ; Švanda,, Michal (referee) ; Svoboda,, David (referee) ; Druckmüller, Miloslav (advisor)
Mnoho vědeckých pozorování a měření, které pracují s obrazovými daty, obsahují krok, ve kterém je nutno dané obrazy registrovat (navzájem sesadit). Výsledky těchto metod tak často silně závisí na přesnosti registrace obrazů. Tato práce popisuje novou, robustní a vysoce přesnou metodu sub-pixelové registrace obrazů (založenou na registraci standardní fázovou korelací) a její aplikace v různých oborech.
