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.

Let There Be Light? Impact of Light Pollution on the Environment
Svoboda, Lukáš ; Mihai, Hana (referee) ; Ellederová, Eva (advisor)
Světelné znečištění patří mezi mnoho druhů znečištění, které ohrožují naši planetu. Důvod jeho vzniku je vedlejší efekt průmyslové civilizace a jeho negativní dopad ohrožuje lidské zdraví, zvěř, rostlinstvo a klima. Cílem této bakalářské práce je vymezit koncept světelného znečištění, popsat způsoby měření a negativní dopady. Teoretická část bakalářské práce se zabývá definováním pojmu světelného znečištění a popisuje způsoby, jakými se světelné znečištění projevuje. Dále řeší možnosti měření světelného znečištění, a také diskutuje negativními dopady na lidské zdraví, přírodu, ekonomiku, bezpečnost a astronomii. Navazující kapitola popisuje parametry běžně užívaných světelných zdrojů pro veřejné osvětlení, a nakonec jsou probírány základní praktiky, které napomáhají snížit světelné znečištění a jsou doplněny příklady správně navrženými svítidly pro venkovní osvětlení. Praktická část této bakalářské práce se zabývá kvantitativním výzkumem, který měl za cíl objasnit úroveň povědomí o světelném znečištění mezi širokou veřejností. Data pro tento výzkum byla shromážděna pomocí dotazníkového šetření.

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.

Subjective tests of influence of the content of the scene on the spatial effect of 3D images and videos
Kaučiarik, Filip ; Kufa, Jan (referee) ; Boleček, Libor (advisor)
This thesis is concerning with study of video sequence parameters which influence the quality of picture during watching 3D frames and videos. It´s focused on comparing individual parameters of video sequences which are spatial and temporal information and depth map range and their influence on subjective testing and assessment of quality of experience by respondents . This thesis contains specification of testing sequence plan based on diversity of video sequence parameters and also a layout of subjective testing. An absolute parameter J was determined to achieve the maximum effect of objective parameters of sequency to 3D effect and comfort of the scene within subjective assessment.

Synthesis of astronomical images
Sauer, Petr ; Babinec, Tomáš (referee) ; Červinka, Luděk (advisor)
The aim of this work is to create a program for fitting astronomical images. The input image is corrupted by atmospheric influences. The work describes the way the alignment and fitting methods. To select appropriately aligned images are used filtration method "Lucky imaging". The program is created in the "Matlab" and is controlled via a graphical user interface.

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.
