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.

Adaptive histogram equalization for digital images processing
Kvapil, Jiří ; Martišek, Karel (referee) ; Druckmüller, Miloslav (advisor)
The diploma thesis is focused on histogram equalization method and his extension by the adaptive boundary. This thesis contains explanations of basic notions on that histogram equalization method was created. Next part is described the human vision and priciples of his imitation. In practical part of this thesis was created software that makes it possible to use methods of adaptive histogram equalization on real images. At the end is showed some results that was reached.

Application of Neural Networks for Human Face Localization
Libosvár, Jakub ; Řezníček, Ivo (referee) ; Španěl, Michal (advisor)
This bachelor thesis deals with detection and localization of human upright faces in images. At first, there are considered current methods. Then the face detection concept is presented. The thesis is focused on practical implementation of artificial neural network-based face detector designed by H. Rowley. Finally, training process and results of detector are discussed in more detail.

Arteries and veins segmentation in retinal images
Šumberová, Dagmara ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This thesis deals with the necessity of vascular segmentation in digital image analysis of the retina and thein subsequent classification.It briefly describes the segmentation of vessels using matched filtering. Next part of this thesis is focused on processing of the retinal images, their manual segmentation and subsequent testing to determine the best discriminating parameters for classification. Finally there is an evaluation of measured parameters and the propřed extension of this method.

Java applets for image processing
Čišecký, Roman ; Číka, Petr (referee) ; Šmirg, Ondřej (advisor)
The bachelor´s thesis is concerned with image processing techniques such as calculating his-togram and its equalization, image filtering in frequency and time domain, creating panoramic pictures and creating a disparity map This thesis describes the various methods of image processing and their use in practice. The last part deals with creating particular applications for image processing and its transformation to applets executable on the web.
