Detecting Presentation Attacks Using Face Spoofing
Homola, Tomáš ; Orság, Filip (referee) ; Goldmann, Tomáš (advisor)
Face detection is one of the most important and widespread methods of verifying a person's identity. However, this method also raises concerns about privacy and security. It is important to be aware of the dangers it brings and constantly develop the necessary means to protect against them. This thesis aims to explain the issue of face spoofing, the threat that arises from a successful attacker's attempt at spoofing, and the detection of these spoofs using algorithms.

I thought I will pause my endless wandering for a while, but I just don´t think I really can
Hrabců, Jamie ; Spáčilová Blažková, Kateřina (referee) ; Javůrek, Tomáš (advisor)
The bachelor's thesis entitled "I thought I will pause my endless wandering for a while, but I just don't think I really can" consists of a series of shirts with applications of patches created by screen printing technique, based on the author's photographs. The photographs are transferred onto the patches by screen printing using special inks, namely heat-sensitive and UV-responsive inks. Formally and thematically, the bachelor thesis is based on the author's previous work. The theme of the thesis is the changing perception of the world and how this perception is influenced by various external or internal factors. The colour used for the patches sewn on the inside of the shirt fabric reacts to the body temperature, the colour layer on the patches on the front side of the shirt reacts to the amount of sunlight and thus to the environment and the time of day. The selection of photographs to be printed and sewn onto the shirts is aimed at creating small wearable "galleries". By wearing the shirts, by varying bodily activity or exposure to sunlight, the viewer-participants can influence the actual form of the images in these "galleries".

HDR Tone Mapping for Low-Light Conditions
Macejka, Lukáš ; Polášek, Tomáš (referee) ; Čadík, Martin (advisor)
This bachelor's thesis focuses on the development and implementation of three specific tone mapping methods into the existing TMS system. The tone mapping process involves converting images with high dynamic range to images with low dynamic range. Its importance lies primarily in its ability to display images originally with high dynamic range on devices that only support standard dynamic resolution. The work thoroughly explains the basic principles of digital imaging and the methods used in this process. Each of the implemented methods is described in detail, and their results are subsequently compared in terms of the quality of the resulting images. The goal of the work is not only to adapt the image according to specific requirements but also to integrate new techniques into the system, which should lead to improved functionality and overall visual quality of the image outputs.

Severin, Svatopluk ; Andreska, Jan (advisor) ; Hanel, Lubomír (referee)
The thesis focuses on visual media in science textbooks and specifically on the diacritical characteristics of animals. The theoretical part concentrates on the textbook, its function and nonverbal media. The thesis elaborate more closely on the form and function in education of illustration and photography. It also discusses the creation of biological illustrations and the work of the illustrator of the groups of animals used in the questionnaire survey. In the practical part, quantitative research through a questionnaire survey determines how students of lower secondary education perceive the diacritical characteristics of selected animals depicted through illustrations and photographs in natural textbooks.

Transformations of manipulation in Czech photography at the turn of 20th and 21st centuries
Růžičková, Tereza ; Francová, Sylva (advisor) ; Magidová, Markéta (referee)
The bachelor thesis deals with the problematics, which has existed since the inception of photography and is constantly becoming more and more current - manipulation in photography. Over a brief overview of the history of photography and the development of manipulation in photography in pre - and (post-) digital production, the thesis focuses primarily on the transformations of manipulation in photography, prompted by the arrival of digital technology in the Czech Republic. The issue is demonstrated through several artists who, from the 1990 s onwards, began to work with new possibilities of manipulation in photography, thus disrupting the traditional view of this medium. In the didactic part, the work focuses on techniques of manipulation with photography that can be used in art classes, especially at the second level of primary schools and secondary schools. The practical part presents a series of author's photographs that disrupt the stereotype of everyday life by means of editing. KEYWORDS photography, digital technology, manipulated photo, manipulation

Contemporary forms of photography in art education
Zavadilová, Šárka ; Francová, Sylva (advisor) ; Magidová, Markéta (referee)
This diploma thesis focuses on the utilization of contemporary photography in art education and its influence on the development of creativity and perception of art among primary and secondary school students. The theoretical part of the thesis presents the evolution of photography over the last thirty years, including definitions of new terms and directions, and introduces the most important authors of this period. In the didactic part of the work, educational programs working with contemporary photography for general high school students are designed, implemented, and evaluated. Finally, an author's portfolio reflecting trends in contemporary fine art photography is presented. The aim of the thesis is to explore various methods and strategies that enable the effective inclusion of digital and post-digital photography in art education and to analyze the benefits of this approach for the development of visual thinking and expressiveness of pupils. KEYWORDS photography, digital photography, art education, didactic transformation, digital competence, digital technology, graphic editors

Shades
Králová, Balbína ; Kovář, Petr (referee) ; Fexová, Patricie (advisor)
The result of my thesis is a set of paintings in dry pastel on canvas. Through the deliberate deformation of figures, which I use as a means of artistic expression, I try to capture the fragile nature of human existence, characterized by instability and transience. The subjects of the resulting paintings are portraits that depict my sisters and me.

Insight
Valentová, Aneta ; Chalánková, Vendula (referee) ; Mikyta, Svätopluk (advisor)
This diploma thesis Insight brings philosophical reflection on photographic media in the form of installation with video-projection in space. Issues over problems of photographic media (locked doubles, stopped time, framed imprint of reality, real raw depiction) are opening by using story about creation of picture of a rabbit on the moon in the style of open metaphors in a white room. Through this myth photographic medium gets the concrete form - in the form of symbolic environment with objets and signs. The whole work is free personification of photograph in whose inside the audience may find themselves.
