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.

Detection of Objects on Belt Conveyer
Láník, Aleš ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
In this master thesis, object's detection in image and tracking these objects in temporal area will be presented. First, theoretical background of the image's preprocessing, image filtration, the foreground extraction, and many others various image's features will be described. Next, design and implementation of detector will be processed. This part of my master thesis containes mainly information about detection of objects on belt conveyer Finally,results, conclusion and many supplementary data such as a photography camera's location will be shown.

Methods for texture analysis in ophthalmologic images
Hanyášová, Lucie ; Szabó, Zoltán (referee) ; Kolář, Radim (advisor)
This thesis is focused on texture analysis methods. The project contains an overview of widely used methods. The main aim of the thesis is to develop a method for texture analysis of retinal images, which will be used for distinction of two patient groups, one with glaucoma eyes and one healthy. It is observed that glaucoma patients don´t have a texture on the eye ground. Preprocessing of the images is found by transfer of the image to different color spaces to achieve the best emphasis of the eye ground texture. Co-occurrence matrix is chosen for texture analysis of this data. The thesis contains detail description of the chosen solutions and feature discussion and the result is a list of features, which can be used for distinction between glaucoma and healthy eyes. The method is implemented in Matlab environment.

Spectral Analysis in Microscopy
Sýs, Michal ; Procházková, Jana (referee) ; Štarha, Pavel (advisor)
The aim of this work is to develop a mathematical apparatus for the accurate description of the colour of objects in a microscope image. This problem is solved by extracting the brightness intensities of pollen grains at fourteen wavelength bands and representing them in color space. The developed apparatus has been successfully applied to two series of images, allowing comparison of the color of individual objects and simplifying its description. The results obtained allow accurate investigation of the colour of objects in the image and form a simple tool for spectral analysis.

Applications supporting lectures in image processing
Hlavatý, Jindřich ; Říha, Kamil (referee) ; Rajmic, Pavel (advisor)
The bachelor thesis deals with development of the programs for supporting of the tuition. The aim of my work is create to set of java applets. Introduction of my thesis explains concepts associated with this topic and necessary for solving this issue. Then I will take a closer look at color models and spaces. The conversion of color models to RGB models are described in this section. The following section shows decomposition into a bit level binary or using Gray code. Then, I will focus on image processing using convolution, conversion color image into gray scale image and dithering. In the end of my thesis the individual java applets are shown and described.
