Effects of pattern, size and background contrast of prey on discrimination learning in avian predators
Kuncová, Aneta ; Exnerová, Alice (advisor) ; Komárek, Stanislav (referee)
The topic of this master thesis was the effects of pattern, size and background contrast of prey on discrimination learning of avian predators. The aim of this study was to investigate the influence of selected components of warning coloration on aversive discrimination learning of avian predators of different age and sex. The choosen model organism was the Great tit (Parus major). The comparision was done between hand-reared naïve birds and wild-caught adults of different age and sex. The experiment was taking place in the experimental cage with one way mirror. The experiment used a design of simultaneous task with two pray which differed in one component of the coloration (pattern, size and background kontrast). The differencies in the ability of discrimination learning was found just between hand-rared naïve birds and wild-caught adults. Better results were shown by the wild-caught adults. The ability of discrimination learning of wild-caught adults was not influenced by the age and sex. Pattern was the only significant component of the warning coloration due to which the birds were able to memorise the discrimination task. Key words: avoidance learning, unpalatable prey, pattern, size, background, contrast

High dynamic range imaging
Kupka, Petr ; Zach, Ondřej (referee) ; Slanina, Martin (advisor)
Bachelor thesis deals with basic principles of increasing the dynamic range of digital photography. The work also looks for the methods that are used to create high dynamic range (HDR) photography, and examines methods for compressing HDR images for low dynamic range (LDR) imaging. Implemented algorithms for tone mapping are performed in HDR_lab program created in Matlab.

textual modifications of Lustig's prose
Peštálová, Lenka ; Peterka, Josef (advisor) ; Mocná, Dagmar (referee)
Cizojazyčné resumé Textual modifications of Lustig's prose The aim of the thesis was to discover the processes of Arnošt Lustig's interference into his previously published work and giving them the final form. The author of this paper was interested in the changes being only supplementary additions of the story or if the meaning is significantly influenced by writer's editing. At the same time, the question about the reason, function and meaning of the changes was raised. For the research three Lustig's books, were chosen: Noc a naděje, Modlitba pro Kateřinu Horovitzovou and Dita Saxová. They slightly vary in genre. The first chapter is about textology. The second chapter Poetics of Arnošt Lustig deals with Judaism as his inspiration, context of the time period in which he was active - the second wave of War prose, the topics of his prose being rather mono-thematically from Jewish background and with his characters, weak and humiliated people who remain moral winners although they often die. The third, fourth and fifth chapter are more about individual books. Their first publication is compared with the last one. The added texts are then sequenced into logical units, described and commented. All chapters contain short conclusion. The last closing chapter presents the results of the thesis. Lustig's...

Modern Imaging Techniques in Medicine
Pařízek, Aleš ; Neuwirthová, Ludmila (referee) ; Rujbrová, Šárka (advisor)
Cílem této práce je popsat základní principy a fyzikální veličiny spjaté s jednotlivými zobrazovacími metodami a poté jednotlivé metody porovnat. Práce popisuje vznik rentgenového záření, jeho interakci s různými materiály a metody snímaní pro vytvoření obrazů. Dále se práce zabývá základním principem vytvoření 3D obrazů pomocí počítačové tomografie a jednotlivými generacemi tomografických strojů. V poslední části se práce věnuje principu nukleární magnetické resonance a základním parametrům pro vytvoření obrazů pomocí MRI systémů.

TOWNHOUSE ON THE WATERFRONT IN PŘEROV
Veselý, Josef ; Wahla, Ivan (referee) ; Nový, Vítězslav (advisor)
Problems arising in the town house near the city center is largely determined by context and situation. The house is not possible to propose no relation to surrounding Material, shape, urban, typology context. Context, therefore, may seem to be anything problematic, but a proper understanding of context and unloading only leads to the correct destination. The house should have all these connections encoded in nature.

Synthesis of astronomical images
Sauer, Petr ; Babinec, Tomáš (referee) ; Červinka, Luděk (advisor)
The aim of this work is to create a program for fitting astronomical images. The input image is corrupted by atmospheric influences. The work describes the way the alignment and fitting methods. To select appropriately aligned images are used filtration method "Lucky imaging". The program is created in the "Matlab" and is controlled via a graphical user interface.

Recognition of Weather in an Outdoor Stationary Camera View
Jenčo, Michal ; Juránková, Markéta (referee) ; Herout, Adam (advisor)
This thesis deals with classification of weather from stationary outdoor camera images with a landscape view. It classifies fog, clear, partly cloudy and overcast weather in particular. The problem was solved by computing five image flags and using machine learning. Hit rate of 95% was achieved with only small variances between weather types. The main finding of this work is that it is possible to successfully differentiate between the selected weather types with the chosen set of simple image flags. The implementation of this system enables plotting a graph of weather progression during a chosen day.
