Time-Gathering Video
Kárníková, Pavlína ; Sumec, Stanislav (referee) ; Herout, Adam (advisor)
This bachelor essay describes problems of creating time-gathering video, image processing and the theory of photography. Purpose is created program, which can modify photos and after that create video. Program is implemented in the C and C++ language and uses the OpenCV library. Application can run in the operation system Windows.

Influence of the different light sources of the vehicle headlights on the perception of an obstacle by the driver of the vehicle
Sklenář, Michal ; Bradáč, Albert (referee) ; Motl, Jakub (advisor)
This thesis focuses on examining the influence of various light sources (halogen, xenon, LED) of vehicle headlights (Škoda Octavia III. generation) on the perception of pedestrians by the driver of the vehicle. The theoretical part contains the concepts essential for a general understanding of the main topic of this thesis. The aim of the thesis is to present how the brightness and contrast between the pedestrian and his surroundings changes when illuminated by one of these light sources due to the increasing distance between the pedestrian and the vehicle and the different type of pedestrian clothing. The results of the measured experiment are presented using charts, photo documentation and brightness maps. These are then compared with the results obtained by measuring the distance of pedestrian perception by individual probands. The conclusions applicable to forensic engineering practice are drawn from the compared values.

Design of lighting system in high school
Borůvka, Jan ; Štěpánek, Jaroslav (referee) ; Škoda, Jan (advisor)
The theoretical part is focused on lights, notions and calculations in the area of light technology, basic lightning sources and lamps. This work is also about the principle of lightning measuring. The main aim of the work is design of a new artificial lightning system in a High school agriculture in Prerov. At first, the control measuring of existing lightning was done which is mentioned in this work. From the results of control measuring is clear, that existing lighting system in classroom does not suit requirements, which are mentioned in the valid technical norm. Design of a new lightning system meets the requirements in all of the rooms in the building of school. Design of lightning system was done in two variants. The first variant uses lamps with fluorescent tube light sources. The second variant uses lamps with LED light sources. Also is here evaluated financial difficulty of possible installation and comparation of each variants with respect energetic difficulty.

Program for monitor testing
Matyáš, Pavel ; Prokeš, Aleš (referee) ; Michálek, Václav (advisor)
The goal of this term project are problems of LCD panels. The beginning of the term project is about theoretical description of particular types and features of actual LCD panels, origin of picture defects on computer monitors, measuring and picture quality testing methods of monitors. Practical part of project involves designing testing patterns and it's realisation in Borland Delphi development environment.

Coulomb Interactions in Electron Beams in the Vicinity of a Schottky and Cold Field Emission Sources
Liška, Ivo ; Kotačka, Libor (referee) ; Radlička, Tomáš (referee) ; Lencová, Bohumila (advisor)
Dizertační práce se zabývá problematikou výpočtu vlivu coulombovských interakcí částic na parametry emitovaného elektronového svazku v blízkosti Schottkyho a studené katody. Práce poskytuje základní předhled o problematice, popisuje vytvořené modely emisních zdrojů a metodu simulace Monte Carlo. Představuje novou metodu generování vstupních dat, která klade větší důraz na přesnou simulaci emisního procesu. Pozornost je zde věnována zejména vlivu interakcí na energiovou šířku, velikost virtuálního zdroje a jas katody v závislosti na velikosti poloměru hrotu a emisním proudu. Sledováním vývoje energiové šířky bylo zjištěno, že naprostá většina interakcí se odehrává v prostoru do několika mikrometrů od hrotu katody. Závislost spočtené celkové energiové šířky na úhlové intenzitě je ve shodě s dostupnými experimentálními daty. Spočtené energiové rozšíření vlivem coulombovských interakcí bylo srovnáno s hodnotami vypočtenými pomocí vzorců založených na analytických přiblíženích. Bylo zjištěno, že některé z nich přijatelně předpovídají trendy ale nemohou být použity pro kvantitativní odhad.

Analysis of pulsations in retinal image data
Plavcová, Daniela ; Kolář, Radim (referee) ; Odstrčilík, Jan (advisor)
Analysis of pulsation in retinal image data can be used to early diagnose of glaucoma. With the record of experimental videoophthalmocope and subsequent segmentation of optic disc the pulsation curves from various parts of optic disc were evaluated and the dependence between brightness, PAA and RNFL parameters was compared.

System for Management of Photographic Collections
Faika, Petr ; Kučiš, Michal (referee) ; Zemčík, Pavel (advisor)
Primary objective of my thesis is the choice, suggestion and implementation of a feature to manage a collection of photos. The current status regarding photography collection is described as well as two existing sotware for that purpose. Description of a photo file, choice of features, suggestion and implementation description follows. I've chosen the feature to merge photos from multiple cameras. At the end of the thesis there's a proof of results and discussion about further extension options.
