Changing Object Appearance by Adding Fur
Pražák, Martin ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
Cílem této práce je demonstrovat možnost renderování srsti přímo do existujících obrazů bez toho, aby bylo po uživateli požadováno překreslení všech pixelů nebo dodání kompletní 3D geometrie a osvětlení. Srst je přidána na povrch objektů pomocí extrakce jejich přibližného tvaru a světelných informací z obrazu a takto získaný objekt je poté přerenderován. Tento přístup je nový v tom, že vysokoúrovňové úpravy obrazu (jako např. přidání srsti), mohou úspěšně vést k vizuálně korektním výsledkům a to i přes omezení nepřesnou geometrií a světelnými podmínkami. Relativně velká množina technik použitých v této práci zahrnuje obrazy s velkým dynamickým rozsahem, metody extrakce 3D tvaru z obrazu, výsledky výzkumu vnímání tvaru a osvětlení a fotorealistické renderování. Hlavním cílem práce je potvrdit koncept popsaný výše. Hlavním implementačním jazykem bylo C++ s použitím knihoven wxWidgets, OpenGL a libTIFF. Renderování bylo realizováno v software 3Delight kompatibilním se standardem Renderman, za pomoci množiny shaderů implementovaných v nativním jazyce Rendermanu.

Human fur patterns and their evolution
Fischer, Jan ; Tureček, Petr (advisor) ; Hora, Martin (referee)
Human fur, although absent on the first sight, is one of human unique features. But the question is, what influences shaped it into its current state. First part ergo the loss of dense fur coat stands on two main hypothesis. The first one being increasing effectivity of sweating for active diurnal lifestyle and the second one being parasite avoidance. There are other hypothesis, although not as reputable. These are aquatic ape hypothesis and importance of fire use hypothesis. The second part are the remaining parts of human fur patterns, some of which even expanded, scalp hair, beards, eyebrows, pubic and axillary hair. Most of these are explained thru hypothesis regarding the importance of communication in expanding human societies but there are also some talking about typical mammalian hair function - environment protection. Scalp hair are mostly explained as health, beauty and individuality signal but it also probably had protective function. Beards as extremely sexually specific trade helped in competition between men although in more of a demonstrative way. They also played role in sexual selection. Eyebrows are irreplaceable in face recognition, emotion expression and they also protect an eye from sweat. Axillary hair preserves armpits and hosts an axillary organ useful in chemical communication....

Is the fur good predictor of intoxification of European beaver (Castor fiber) populations?
Faltová, Karolína ; Vorel, Aleš (advisor) ; Korbelová, Jana (referee)
This thesis deals with the burden of European beaver (Castor fiber) populations with risk elements in three areas of the Czech Republic and one area in Slovakia. There were investigated concentrations of heavy metals (Cd, Zn, Fe, Cu, Pb and As) in the kidneys, livers, lungs, hearts, muscles and fur of 19 found dead beaver individuals. Furthermore, their food was analysed to determine the contamination of their areas of origin and discover, which organ reflects the observed concentrations of Cd the best. The main aim of the study was to determine whether the analysis of hair could be used as a non-invasive method to reflect the concentrations of heavy metals in beaver populations in future. The results were conclusive only for As, whose concentrations in the hair was the second highest and correlated with the content of As in the lungs, which contained the highest concentrations of arsenic. Cadmium in the fur showed a reverse structure compared to the content of Cd in kidney and liver. There were found significant differences in the contamination with heavy metals between beaver populations and their environments. Analysis of the fur is not proved for most of the elements and it is necessary to investigate further non-invasive methods to determine the load of toxic elements on beaver populations.

Exterior changes during dog domestication
Wagnerová, Lucie ; Hofmanová, Barbora (advisor) ; Čapková, Zuzana (referee)
Domestication of a dog is a long-term proces which consists of series of modifications of various physiological and behavioral traits. There are several different opinions on the period when domestication started and on the original reasons of domestication. Archeological excavations of wolf skeletons were founded in Southeast Asia, America and in Europe. The oldest findings are 150000 years old. These excavations were especially found in China. Younger findings are 15000 - 33000 years old. Study of mitochondrial DNA supports the idea that the main center of domestication is the Southeast Asia. Currently there are two regions considered to be the center of domestication - Southeast Asia and Middle East.
The idea that wolf is an ancestor of a dog can be proved by the excavations found for example in Germany or in Předmostí u Přerova in Czech Republic.
During the domestication process there has been several changes at dogs - ethological changes and changes of the exterior of a dog. Behavior, vocalisation and response to human signals belong to ethological changes. Changes of exterior are especcially change of skin, length of limbs, shape and position of ears, size of skull, structure, length and colour of fur. Three types of skull can be found at current breeds - brachycephalic, mesocephalic and dolichocephalic skull. Dogs with the brachycephalic skull can suffer some health problems more often. There are three main genes which influence the structure and length of fur - RSPO2, FGF5 and KRT71. Based on these genes there were described mutations which influence different length of fur and different structure of fur. Relating absence of fur at several breed (for example Peruvian Hairless Dog) there were described mutations of gene FOX13. The coloring of fur is affected by productions of two types of melanin - eumelanin and feomelanin. Production of these pigments is controlled especially by genes MC1R, CBD103, ASIP, TYRP1. In this work we will compare all these changes (exterior and ethological) with the ancestor of dog - with a wolf.

The effect of structure and color of the hair dogs on their application in canistherapy
Šedová, Markéta ; Fiala Šebková, Naděžda (advisor) ; Chmelíková, Eva (referee)
This bachelor´s thesis has the character of a scientific literary review. This work follows up a specific kind of therapy, where dogs are doctors of human souls, but also describes structure and color of the hair of dogs.
Our primary aim is to introducenetwork of facts representing that structure and color of dog´s hair is related to value, effectivity and quality of their role as a therapist.
The first chapter covers the skin system and its function. The second chapter concerns hair follicle and its associated structures. We are also concerned with information about different types of hair, its structure and exchange. In this chapter, we inquire the coat of the dog and the care about it, as well as skin diseases and resultant examinations. The penultimate chapter is devoted to hereditary characteristics of coat color like chemical substance pigmentation of hair and color genotypes of Small Münsterländer, Pyrenean mountain dog and shih-tzu. I have chosen such breeds because I cooperate with their representants in my owh canistherapy, where my supervisor is a very experienced therapist Monika Posekaná. The last chapter deals with canistherapy in general. In this part, I provide information about the history od canistherapyin the Czech Republic, list of animals that took part in therapied during the 20th century, utilization of canistherapy, standards for selecting a suitable dog for therapy; the last part commentssome aspects of animal assisted therapy in homes for the elderly. From my point of view, this part is crucial, especially for its practical ground. My bitch and me come to help to such houses regularly and very intensively.
