Automated object tracking using robotic manipulator
Zelený, Miroslav ; Ligocki, Adam (referee) ; Chromý, Adam (advisor)
This diploma thesis deals with the tracking of objects using a robotic manipulator Epson C3 and a color camera. The work describes the basic qualities of the device to be used. The OpenCV library and its wrapper EmguCV are used as software tools for computer vision. It discusses the basic issues and principles of tracking objects in the image and introduces some methods of tracking. These methods have been tested and therefore their strengths and weaknesses, which appeared during testing, are listed here. Furthermore, there is a procedure for calculating the new coordinates of the camera and the manipulator effector using homogeneous transformations. The work contains the results of testing the algorithms and their evaluation. The output of the work is a test application for the Epson C3 robot.

Zahrádka, Jiří ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This thesis falls into a field of user interface design. It focuses on tangible user interfaces which utilize a camera and projector to augment physical objects with a digital information. It also includes description of calibration of those devices. The primary object of this thesis is the implementation of an augmented user interface for application windows management. The system consists of a stationary camera, overhead projector and movable tangible objects - boards. The boards are equipped with fiducial markers, in order to be tracked in a camera image. The projector displays the conventional desktop onto the table and the tangible objects. For example, application windows can be projected onto some boards, while the windows move and rotate simultaneously with the boards.
Eye Tracking During Interaction with a Screen
Pavelková, Alena ; Kajan, Rudolf (referee) ; Herout, Adam (advisor)
Tato práce popisuje systém pro sledování obrazovky počítače v reálném čase a určení pozice uživatelova pohledu na tuto obrazovku s využitím dat z eye-trackovacích brýlí a Uniform Marker Fields. Vytvořený systém lokalizuje obrazovku počítače ve snímcích z kamery umístěné na eye-trackeru snímající scénu před uživatelem. V této scéně je detekován marker zobrazený na monitoru počítače. Po jeho úspěšné detekci je marker skryt a ke sledování pozice obrazovky jsou dále využívány významné body detekované ve snímku z kamery ležící na obrazovce, případně z celého snímku. Pokud sledování významných bodů selže, marker je znovu zobrazen a systém je znovu inicializován pomocí detekovaného markeru. Aby byl marker pro uživatele co nejméně nápadný a obtěžující, jsou využity data z eye-trackeru k tomu, aby byl marker zobrazen co nejdále od oblasti uživatelova zájmu. Pro vyhodnocení výkonu a přesnosti vytvořeného systému a rušivosti markeru pro uživatele bylo provedeno několik experimentů a testování s uživateli.
Augmented User Interface
Vladík, Ondřej ; Beran, Vítězslav (referee) ; Najman, Pavel (advisor)
The purpose of this thesis is to design and implement an augmented user interface for widget management which uses a camera-projector system. Implement also includes a library of functions for semi-automatic calibration of this system. An interface to control the widgets using markers was designed. Various markers are arranged on the desktop (desk, wall or table) . The camera captures these markers in a camera image.The position of the markers in space is then determined from the camera image . Widgets are projected on the desktop next to the markers. User can freely move those markers and the widgets will follow the markers.

PharmDr. Josef Malý, Ph.D. Consultant: PharmDr. Petr Domecký Department of Social and Clinical Pharmacy, Faculty of Pharmacy in Hradec Králové, Charles University Introduction and aims: Periprosthetic joint infections are considered as the biggest complication of the implementation of the total arthroplasty which may be reduced by the observation of inflammatory and nutritional markers. The aim of this thesis is to analyse the possibilities of influencing the antibiotic prophylaxis (AP) on the basis of those markers observed on patients that underwent the total hip arthroplasty (THA) and the total knee arthroplasty (TKA). Methods: Data was collected from a prospective study which began in March 2020 at the Department of Orthopedics at the University Hospital Hradec Králové. There were 118 patients from May 2021 to June 2022 older than 18 years with THA and TKA included in the analysis. The analysed data were sourced from the paper and electronic forms of medical documentary materials of those patients. Patients'personal and medical details (including the information about the operation, the thromboprophylaxis (TP), AP, and the results of physical and...
Methodology for identification of pollution sources using PMF for strategic decision making in air protection - update 2023
Horník, Štěpán ; Sýkora, Jan ; Pokorná, Petra
The presented methodology proposes utilizatíon of the spectroscopy of nuclear magnetic resonance (NMR) as another analytical technique for the identification of compounds in atmospheric aerosols. This technique makes significantly increases the number of deterined substances and thus a number of possible markers, which can be subsequently used together with other methods to identify sources of air pollution using advanced statistical\nanalysis. Among the markers determined by NMR spectroscopy there are several organic and sulfonic acids or carbohydrates, wich are characteristic for relevant sources of air pollution. The updated methodology also shows the identification of a biogenic source that previous methodologies were not able to determine.

Study of inflammation using epithelial cells
Majerová, Barbora ; Hodek, Petr (advisor) ; Koblihová, Jitka (referee)
The human respiratory system is in constant contact with heterogeneous agents from the environment. There must be effective mechanical lung barriers and sufficient immune protection due to continuous deposition of various substances in the respiratory system. The mutual balance between the mechanisms of natural and adaptive immunity of the lungs is essential for destruction of infectious agents without initiation of inflammatory response. Overreaction of the immune system of the lungs may lead to the production of various inflammatory mediators and cytokines such as interleukins IL-1, IL-6 and IL-18. When determining the immunogenicity of a substance, it has to be exposed to lung epithelial cells, and then the concentration of cytokines produced is measured. To determine the immunogenicity of mammalian immunoglobulin G and chicken immunoglobulin Y the subsequent twenty-four hour exposure to A549 lung cancer cell line was made. Concentration measurement of cytokines IL-1 and IL-6 was performed using Luminex method, which pointed out the immunogenicity of goat immunoglobulin G and certain chicken immunoglobulins Y.
