Interactive applets supporting teaching digital image processing
Křivánek, Jiří ; Mangová, Marie (referee) ; Rajmic, Pavel (advisor)
This thesis deals with the creation of applications for support of education computer graphics. The aim is to create a simple application which will show the functioning of the various methods. I implemented convolution methods for image filtering, dithering engaged in the distribution errors, bit planes that show each bit plane image, gamma correction to lighten or darken the image and procedural textures. All these methods are created in the form of Java applets.

Preprocessing of 1D gel electrophoresis image
Svozilová, Veronika ; Škutková, Helena (referee) ; Vítek, Martin (advisor)
The aim of this work is to propose an algorithm in MATLAB, allowing image processing and evaluation of one-dimensional gel electrophoresis. At first describes the detection of samples based on the horizontal segmentation of electrophoresis gel image, followed by detection of the minimum intensity values of the image, a vertical segmentation and determination of the sample boundaries in the image. The final phase involves testing of the method on publicly available images and evaluation of the results.

Application for Editing the Histogram
Nezhyba, Jiří ; Kohoutek, Michal (referee) ; Říha, Kamil (advisor)
The object of this bachelor‘s thesis is create an application for editing the histogram. The program is realized by programming language C++ and programming tool Microsoft Visual C++ 2005 Express Edition. It defines fundamental terms for this work as histogram or transformation of grey level scale. Above all, it analyses individual grey level transformations, which used for editing the histogram. It describes designing and realization of application. Input data of program is any input digital image, which user order, selected grey level transformation and its parameters. Output data are input image in grey levels, histogram input image, transformed input image and its histogram. Output images can be saved.

Digital filters for image processing
Všetička, Václav ; Říha, Kamil (referee) ; Číka, Petr (advisor)
This work is dedicated to methods for editing the digital image. When you need an suitable algorithm to highlight the desired information from the image, or conversely, suppress disturbing elements in the picture. This work describes a few most basic image editing filters to use common in technical and medical practice. The result of this work are implementing some filters into Java.

Time-Lapse Video
Jirka, Roman ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
This thesis deals with the introduction into the topic of time-lapse video creation. It focuses on cases where tripod is not used and therefore it is necessary to eliminate incurred shortcomings. The main shortcomings are different position of individual frames, different brightness and color adjustment. The next topic describes which principles should be followed during the creation process. Thesis describes and implements methods for elimination of main shortcomings during process long time-lapse videos, which are recorded by hand. Thesis also precisely describes image registration, correction of brightness and colors. Thesis is also considers histograms comparison. Result of this work is application, which eliminates problems described above.
