Optimization of the experimental parameters for laser induced breakdown spectroscopy (LIBS) of selected plant samples
Prochazka, David ; Novotný, Karel (referee) ; Kaiser, Jozef (advisor)
This diploma thesis describes optimization of the experimental parameters for Laser-induced breakdown spectroscopy of plant samples. First part deals with the theoretical method of LIBS and explains the principles and terms. In the next part there is described device which was used for measurements. Main part of diploma thesis describes creation of program for measurement-automation. Main task of program was to solve the connection of autofocus on the sample with the sample automatic movement. Furthermore are described and elaborated specific measurements for optimization of the experimental parameters for Laser-induced breakdown spectroscopy of plant samples.

Autofocus using CAN-EF interface
Ižarík, Marek ; Nováček, Petr (referee) ; Honec, Peter (advisor)
The main topic of this master thesis is creating, testing and implementation of algorithms for autofocus with Canon camera lens using CAN-EF interface, while one of the assignments is possibility to continuous focus to the vehicle in traffic monitoring. There are tested a number of criteria for the assessment if sharpness in the image and is designed automatic control system of the lens and camera.

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.

Modern methods for digital scene capturing
Nováček, Petr ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
The thesis composes conventional and modern methods for digital scene capturing. The target of the thesis is a comparison of CMOS with Bayer mask and Foveon X3 Merrill sensors followed by a design of algorithms for image fusion which can combine advantages of the both sensor types. The thesis starts with an introduction and a description of methods and processes leading to scene capturing. The next part deals with capturing a gallery of test images and with a comparison of both sensors based on the gallery images. Further there are algorithms designed for image fusion which can combine advantages of the selected sensors. The last part of the thesis is devoted to an evaluation of results and of the used algorithms.

Software for the Spectroscopy Method LIBS
Vyroubalová, Jana ; Mráček, Štěpán (referee) ; Orság, Filip (advisor)
This thesis discusses creating of software for the LIBS spectroscopy method (for an electronic chamber). In the first part the reader will learn about the LIBS method and about a short description of a workplace, where the project is being created. Then I write about an application design for laboratories, which are going to use this method. Next I describe an implementation of software, where the reader can find some details about used algorithms for autofocus (an evaluation of image sharpness and an iterative determination of the position of the camera). The end of this work is focused on the assessment of GUI and testing the application.

System for maintaining the sharpness of the image for the light microscope
Dokulil, Jakub ; Bouchal, Petr (referee) ; Dostál, Zbyněk (advisor)
Live imaging je klíčovým nástrojem pro moderní biologické objevy. Bez techniky pro udržení ostrosti obrazu je však stěží proveditelný. V této práci předkládám aplikaci optických vírů pro axiální lokalizaci vzorku tak, aby se obraz mikroskopu udržoval zaostřený. Experimentalní sestava pro axiální lokalizaci z předchozích experimentů byla přepracována, aby se rapidně zmenšily její zástavbové rozměry, tak, aby jí bylo možné integrovat jako modul do mikroskopu. Sestava byla následně realizována a byla úspěšně experimentálně otestována. K tomu bylo třeba také navrhnout řídící software. A připravit skript se zpětnou vazbou pro budoucí integraci do mikroskopu.
