User Interface Using WWW for Photo Image Analysis
Balcárek, Lukáš ; Láník, Aleš (referee) ; Zemčík, Pavel (advisor)
This master's thesis deals with the user interface for machine quality assessment of the technical groups of photos. This work is written about photos, graphics editors and their evaluation. The practical part is focused on the design and creation of application with web user interface, which evaluates and compares the quality of photos. Finally is this created application with its user interface tested by users, its benefits and opportunities for further expansion are evaluated.

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.

Image similarity based on colour
Hampl, Filip ; Přinosil, Jiří (referee) ; Uher, Václav (advisor)
This diploma thesis deals with image similarity based on colour. There are discussed necessary theoretical basis for better understanding of this topic. These basis are color models, that are implemented in work, principle of creating the histogram and its comparing. Next chapter deals with summary of recent progress in the field of image comparison and overview of several most used methods. Practical part introduces training image database, which gives results of success for each created method. These methods are separately described, including their principles and achieved results. In the very end of this work, user interface is described. This interface provides a transparent presentation of the results for the chosen method.

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.

Proxy Server for Mobile Devices
Vašenka, Václav ; Chmelař, Petr (referee) ; Weiss, Petr (advisor)
This thesis should introduce principles of proxy servers. Main focus is on using proxy as a mediator between a web user, accessing the web from mobile devices and a web server. Next, this paper deals with web design and with aspects that have affect the speed and effectiveness of web page browsing via a proxy server. Moreover, the realization of such a system is described in this paper.

User interface for adaptive RCL modules
Novitchi, Dumitru ; Frýza, Tomáš (referee) ; Kubíček, Michal (advisor)
The purpose of this thesis is to create an simple graphic library in the programming C language, through which it will be possible to draw and simulate the basic functions of a car backlight, and subseguently to create the graphic user interface.v The first part of the thesis is based on the study of the given issue, briefly it describes the differences between raster and vector graphics,most used formats, describes diverse color models and the area of their use, ,basic graphic adapters, video memorry and its control in the operating system Linux. In the second part there is stated the practical realization of the basic graphic algorithms needed for drawing the algorithm primitives. An mathematical aparatus described in detail and well-founded with formulas. Also there are the advantages and disatvantages of each used algorithm and their realization in the programming C language. The 3rd and the last part of the thesis is dedicated to the creation of the graphic user interface in the FreePascal programming language and further to the describtion of his main elements.
