Optical Method to Evaluate the Contractile Function of Isolated Cardiac Myocytes
Kopečný, Josef ; Harabiš, Vratislav (referee) ; Čmiel, Vratislav (advisor)
In this master´s thesis we will firstly focused on the description of a cyte in terms of structure as well as in terms of electrical and chemical processes. We will examine a processes, which make a contraction and the processes on cyte membrane. We will also analyse image processing methods and methods for measuring the contraction. The block diagram will be designed and requirements for the measuring platform will be specified. The programme will be realized in LabWIEV programming language.

Program for deinterlacing in video sequences of different formats
Jirků, Pavel ; Kratochvíl, Tomáš (referee) ; Slanina, Martin (advisor)
The aim of this thesis is a study of advanced algorithms for removing interlacing in digital video sequences. The first part of the work is devoted to the theory, basic knowledge and processing characteristics using multimedia data. The second part is devoted to displaying the signal using interlaced and progressive spacing. The following part is focused on methods of conversion between the interlaced line spacing and progressive spacing. The last part deals with implementation of the proposed methods. The algorithm is implemented in C++ language, which provides sufficiently fast processing algorithms. The conclusion of work is focused in testing and verification of the implemented algorithms.

Development of IMS platform applications
Martinek, Pavel ; Nagy, Ľuboš (referee) ; Mácha, Tomáš (advisor)
This master’s thesis is focused on the network architecture of IMS (Internet Protocol Multimedia Subsystem) and development an application for IMS. IMS architecture is the convergence of fixed and mobile networks. IMS enables rapid deployment of new multimedia services. In the first chapter is showed and described architecture IMS in four layers and block model of architecture IMS. Next chapter is focused to protocols, which are used in IMS. One of the most important protocols in network IMS is SIP. This protocol is analyzed in details. For development IMS platform application was used Ericsson SDS (Service Development Studio) in version 4.1. In SDS were created applications type of client and servlet. In this master’s thesis is also used development environment NetBeans. In NetBeans was created application for management of captured images. In the same development environment was developed application that shows the contents of a database. Last chapter is devoted to analyze individual parts of communication between client and servlet, and when client uses http to download image file.

PPTX to HTML Conversion
Vilímek, Hynek ; Szentandrási, István (referee) ; Herout, Adam (advisor)
PowerPoint is an excellent tool for creating presentations and people are accustomed to using it. Its only handicap is that it is not installed everywhere and it exists in numerous versions. But there is an application that is installed almost everywhere and that application is the web browser. This work aims to create the PowerPoint presentation viewer for the web browser. With the internet as the environment, it may have a wide range of applications from the content sharing point of view. The solution is a web application that allows to upload the PowerPoint file and then the application displays the content of the file. The application also offers functionality such as navigation between slides and full-screen mode. The rendered slides in the web browser are very similar to the slides in PowerPoint. It does not support advanced features, but it supports displaying text, pictures, video and audio. Further, it supports basic styling options such as colours, margins, position and line height.

Software for manual focus of camera with 4K resolution
Sláma, Adam ; Přinosil, Jiří (referee) ; Kříž, Petr (advisor)
This Master thesis is focused on the analysis of currently used methods which whose target is to determine the rate of image focus. This analysis was used during the development of the program which evaluates the rate of image focus in percentage rate, works in real time and cooperates with a camera capable of 4k image resolution with a manual focus of the lenses. Application is then capable of a finding of a pre-defined image under certain circumstances which is being used for increasing of effectivity of image focusing. Another option is represented by a method that is searching the most suitable area for focusing in the center of the image. A detailed description of these methods and program itself are also included in the thesis. The final part of the thesis contains records of measurement tests with its results.

3D model of selected object
Ptáček, Pavel ; Vacková, Eva (referee) ; Bartoněk, Dalibor (advisor)
The objective of this diploma thesis is creating digital 3D model of Dolní morový hřbitov in Žďár nad Sázavou. The building is measured primarily by classical geodetic methods. The final appearance of the model is created in AutoCAD 2015. Complementary are presented additional possibilities for creating digital models of building objects and their associated advantages and disadvantages. Much attention is paid to the photogrammetric method based on correlation of images, and work with the program 123D Catch and Cinema 4D.

Arc optical diagnostics
Čermák, Jiří ; Valenta, Jiří (referee) ; Dohnal, Petr (advisor)
The aim of this bachelor thesis is to sort out the individual types of electric discharges, explain the ionization inside the plazma of the electric arc and the elucidation of the energetic balance inside the plazma. The electric arc is an undesirable and hardly predictable phenomenon occurring in switching devices during switching on and switching off the electric circuit. Some older methods of image processing obtained by a high-speed camera are also mentioned. Based on the images obtained from the camera, it is possible to make an equidensity or an equidensitogram that is used to monitor the arc in a quenching chamber. The second part includes the description of an experiment performed in a laboratory and the description of the high-speed camera used during this experiment. A modern method of the image processing using software Matlab is also described. An equidensitogram showing different levels of radioation was made in Matlab from the obtained images.
