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.
Security Icon Checking Application
Ružička, Vladimír ; Jirák, Ota (referee) ; Ruttkay, Ladislav (advisor)
This work is about icons in Windows systems and about their format. The work shows the way, how the system use them and how malware can profit on icons. It explore how icons can be compared one to another. The work contains application, which tests icons.
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.
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.
