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.
