Methods of image dithering
Pelc, Lukáš ; Křupka, Aleš (referee) ; Rajmic, Pavel (advisor)
Master’s thesis discusses methods for dithering image. The basis is the explanation of the theory of digital images, color models, color depth and color range. Followed by the dismantling of the basic dithering methods which are a thresholding method, a random and matrix diffusion. Discussed are advanced methods of dithering with error distribution, bee with best known method Floyd-Steinberg. Included is a comparison of different methods including subjective comparison using a questionnaire. Program part is JAVA applet that shows the possibility of generating images using various dithering methods.

Dithering the image
Štefaník, Pavel ; Zátyik, Ján (referee) ; Rajmic, Pavel (advisor)
Bachelor work deals with the reducing of picture color depth by various dithering methods. These methods are compared between each other and demonstrated on various types of pictures. Each method is described and implemented in MATLAB. The results are compared from different angles: time duration of algorithm, survey based on form, my opinion and SSIM comparison.

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.
