Laboratory site for color measurement in video technology
Melo, Jan ; Kejík, Petr (referee) ; Slanina, Martin (advisor)
The diploma thesis is dividend into four parts. The first part describes basic terms in video technology (luminance, hue, diagrams CIE). The second part includes types of colour spaces RGB, HSV, CMY(K), YUV, YCbCr, YIQ. In the third and fourth part, these theoretical findings are used to propound laboratory observations. The laboratory observation processes the colour rendition of the colours in video technology. In the Matlab software, a user system environment was developed for operations with measured values. The software is capable of recalculating chromaticity coordinates between different colour spaces, to screen colours into diagrams CIE and to show the vectors of colours. The device used for measuring was Chromametr Konica Minolta CS-100A. A manual for the device was created. The laboratory observation was measured and processed in the form of a laboratory protocol.

Interactive web applications for education of color theory
Koroleva, Anfisa ; Přinosil, Jiří (referee) ; Rajmic, Pavel (advisor)
This bachelor thesis deals with the issue of interpretation of colors and color images in computer graphics. Specifically, the work is focused on the development of simple web applications – applets that will serve for interactive submission of methods used in the field of computer processing of color images. The created applets should demonstrate the relevant theory relating to color mixing in different color models, conversion of a color image to a gray-scale image, conversion of a gray-scale image to a false-color image, conversion of physical light into CIE XYZ and L*a*b* color spaces. The first part of the thesis describes the theoretical basis for the required applets. The following practical part is dedicated to the process of implementing the applets using JavaScript and HTML.

An application for color coordinate transforms and color mixing
Jurzykowski, Michal ; Štukavec, Radim (referee) ; Slanina, Martin (advisor)
The most important human sense is sight. We can see thanks to eyes, which are very sensitive on small part of electromagnetic wave. White sunlight contents all the spectrum visible. By decomposition of white sunlight we get colour spectrum. We recognize colours by cones, which are sensitive on red, green and blue spectrum of white light. Informer times it was denited many colour models, which have been using additive and subtractive method od mixing colours. One of the first models which were matemacily defined was CIE 1931, also known as XYZ. Together with this model was created xy chromatic diagram for displaying of colour space. Best known colour models are RGB and CMY. In TV technics is used model YUV. Models HSV and HSL are more intuitiv. This models have three basic parameters: hue, saturation and brightness.

Interactive web applications for image processing education
Krolop, Filip ; Záviška, Pavel (referee) ; Rajmic, Pavel (advisor)
Introduction to theory related to applets that will be used for educational purposes, creation of custom design, draft of their basic functionality and control elements, followed by own implementation and optimization. This is an interactive submission of image processing algorithms specifically, applets are focused on color models, their relationships and calculations between each other: 1 / Pallet (index) image representation, 2 / Colormixing in different models, 3 / Color image conversion to grayscale image, 4 / Conversion of a grayscale image to color image (false colors). Applets implemented using HTMLand JavaScript to demonstrate the theory and encourage students to interact.

Education Computer Program for Demonstration of Images Colors Space Reduction Methods
Pekař, Daniel ; Švub, Miroslav (referee) ; Štancl, Vít (advisor)
This work describes an Education Computer Program for Demonstration of Images Colors Space Reduction Methods creation. This program does not only constitute a means to reduce colors space in images but adverts to principles of individual reduction methods as well. The possibilities of program´s employment expand due to theoretical background´s incorporation into a practical application. The program can be in service as a reduction methods´demonstration tool in a class or as a study material for an individual learner.
