Detection of Diseases of Diabetes on the Human Eye Retina
Sýkorová, Tereza ; Semerád, Lukáš (referee) ; Drahanský, Martin (advisor)
This bachelor's thesis deals with the detection of the symptoms of diabetic retinopathy at retinal images taken by a digital fundus camera. Optic disc, fovea, and blood vessels are found before searching for exudates and hemorrhages. This step improves final detection. The detector uses morphological reconstruction of a candidate region for determination of specific lesions. An algorithm based on thresholding precises its edges. Found regions are classified according to shape and color. Evaluation of detection was done using 120 images selected from three databases. Adding automatic detection of signs of diabetic retinopathy into equipment for retinal screening can help medical doctors in diagnosis and prevent possible vision loss which the disease can cause.

Automatic Image Analysis for Production Quality Control of Textile
Sýkorová, Tereza ; Dobeš, Petr (referee) ; Zemčík, Pavel (advisor)
This work deals with the classification of defects that occur in the production of nonwovens. The defect classification task is part of a system for automatic production quality control. The goal is to implement a method that will classify problematic defect classes with sufficient accuracy. That was achieved using convolutional neural networks (CNN). The best results were achieved by the EfficientNet network, which had an accuracy of 81% when evaluated by cross-validation on an available dataset. Within the work, a number of experiments are performed, which are focused on the modification of input data. The influence of the shape and composition of the input images on the final classification is examined. A CNN model was also implemented, which uses additional information for classification in addition to the image.

Bedřich Kocek and czech press photography
Sýkorová, Tereza ; Láb, Filip (advisor) ; Géla, František (referee)
The master thesis Bedřich Kocek and Czech Press Photography is concerned with the life and work of Bedřich Kocek - Czech photojournalist who worked in the renowned journal Svět v obrazech (translated as World in Pictures) for over thirty years. The theoretical part specifies the genre of journalistic photography and its development from the turn of the 19th and 20th centuries to the 1980s. Furthermore, the development of the journal Svět v obrazech serves as an example for outlining the media and political context in Czechoslovakia since the end of World War II, when the periodical was established, until the 1980s, when Bedřich Kocek left the profession of a photojournalist. An especially valuable and vital part of the thesis is a chapter about the life of Bedřich Kocek, which has not been previously researched and described in detail. That section is based on personal interviews with the photographer using the oral history method. Moreover, the thesis explores the photographic work of Bedřich Kocek through the use of compositional analysis as well as the characteristic features of his pictures, which were part of the reports produced for Svět v obrazech.

Travel Journalism in Selected Czech Media
Sýkorová, Tereza ; Němcová Tejkalová, Alice (advisor) ; Jirků, Jan (referee)
The theme of this bachelor thesis is travel journalism; despite being a lifestyle genre, it provides important information about the image of the world. The object of this work is to analyse selected travel articles in the Czech National Geographic magazine, Koktejl magazine and on the Big trip blog during the given period from July until December 2015. The Czech National Geographic magazine is a branch of American National Geographic, where most of the articles are translated from the original version. Koktejl is a Czech geographic magazine with articles written by local authors. Big trip is a personal blog of Ladislav Bezděk and Kateřina Dvořáková; therefore the texts published there are different than those published in the magazines. Researched travelogues are divided by media and cultural resemblance. The aim of the work is to determine, using the qualitative content analysis, in what way the chosen media inform about the areas contained in the texts. This bachelor thesis pays attention to the representation of the world, text range, style, and the position that the geography of travel journalism has in comparison with the geography of foreign news. The theoretical segment contains the characteristic of the chosen media and travel journalism, and is based mainly on foreign literature.

The Analysis of Personal Identity in Hume's Treatise of Human Nature
Sýkorová, Tereza ; Palkoska, Jan (advisor) ; Karásek, Jindřich (referee)
This bachelor's thesis puts forward an interpretation of David Hume's analysis of personal identity in his Treatise of Human Nature, as well as an interpretation of his subsequent doubts expressed in the Appendix. In the first part of the thesis an interpretation of Hume's theory of mind as a "bundle of perceptions", as well as an interpretation of his explanation of our propension to regard this bundle as a synchronically and diachronically identical entity is presented, after an introduction describing the philosophical discourse around personal identity, Hume's conception of philosophy and his revisionist ontology. In the second part an interpretation of the passage from the Appendix is presented, in which Hume expresses dissatisfaction with his account of personal identity. In this thesis I hold the view that the main source of Hume's dissatisfaction is the fact that the idea of the mind as a collection of all present perceptions interconnected through causal relations, which Hume held for a true idea and which serves as an implied foundation of the whole first book of the Treatise, turned out to be fictitious, just as all the other metaphysical ideas. His explanation of our propension to regard the collection of perceptions as a synchronically and diachronically identical entity, which is...
