Automatic vocal-oriented recognition of human emotions
Houdek, Miroslav ; Přinosil, Jiří (referee) ; Atassi, Hicham (advisor)
This master thesis concerns with emotional states and gender recognition on the basis of speech signal analysis. We used various prosodic and cepstral features for the description of the speech signal. In the text we describe non-invasive methods for glottal pulses estimation. The described features of speech were implemented in MATLAB. For their classification we used the GMM classifier, which uses the Gaussian probability distribution for modeling a feature space. Furthermore, we constructed a system for recognition of emotional states of the speaker and a system for gender recognition from speech. We tested the success of created systems with several features on speech signal segments of various lengths and compared the results. In the last part we tested the influence of speaker and gender on the success of emotional states recognition.

Identification of emotional state using speech signal analysis
Navrátil, Michal ; Atassi, Hicham (referee) ; Smékal, Zdeněk (advisor)
The diploma thesis deals with the analysis of human emotional states speaker by the help of analyse speech signals. The thesis has two parts. In the first part, the process of speech generating is described in addition to the description of the commonly used pre-processing methods such as denoising or preemphasis. The first part also deals with the major and minor prosody features, these features are: the fundamental frequency, energy, spectral features and time domain features such as the speech rate. The second part of this thesis deals with a task of emotion recognition from the speech signal. When we accumulate sufficient of the number of recordings emotive state will be able to rekognize emotive state with high probability. All project is prepared for use in real time. The last part of this thesis thesis contains description and results of the experiments made on a large number of speech records.

Human preferences to primate species and their consequences
Zelenková, Michaela ; Frynta, Daniel (advisor) ; Sedláček, František (referee)
One of the most important traits of an individual is the appearance. Though mankind desires to unlock the "beauty code" for centuries, it is very difficult to do so. A lot of papers focuses on the characterization of appearance and preferences towards it. It is now obvious that instead of using just one factor to describe the nature of "beauty", we need to comprehend a lot of factors that put together the puzzle pieces of an attractive individual. Nowadays, a widely accepted fact is that symmetry makes facial and other body features attractive. Other important factors are averageness or so-called baby schema with distinct young features. Similar rules apply for evaluation of preferences towards other, non-human species, especially primates. The most attractive primates have facial features that resemble humans or that are round with big, distinctive eyes (baby-schema). Thus, for humans, the most attractive primates are the ones that are similar to us and that are large in body size, while the unattractive ones have an appearance distinctive to humans. Moreover, humans distinguish two main primate faces: nice and friendly, baby-like faces, and aggressive, dangerous faces.

Thrown into reality: Beginning teachers'expectations confronted with professional practice (radio documentary)
Štylerová, Valérie ; Štoll, Martin (advisor) ; Čeňková, Jana (referee)
This practical bachelor's thesis, which includes a 16-minute radio documentary titled Thrown into Reality, deals with the study preparation and professional beginnings of graduates in teaching disciplines and their original expectations compared to the reality of pedagogical practice. Given the ambiguity of the radio documentary genre, which oscillates on the border of journalistic and artistic style, one of the goals of this theoretical part of the work is to provide insight into this genre in comparison with other journalistic genres, which are very close to its definition and characteristics (feature, band, reportage). The primary way of obtaining information for this document - a dialogue or interview - is also shortly described. One of the subchapters presents several examples of contemporary Czech radio documentaries. In the second part, the topic of radio document itself is introduced, namely the most common issues of beginning teachers and the introduction of recent graduates to their first job position, followed by author's reflection of the work. The radio documentary consists of authentic testimonies of beginning teachers and statements of other relevant respondents connected by the entries of the moderator. The aim of this entire thesis is to provide the listener with the life...

Weapon as a work of art. With focus on problems of specific weapons identity and interpretation of weapon as feature
Schartel, Tomáš ; Sýkora, Ondřej (advisor) ; Filip, Michal (referee)
TITLE: Weapon as a work of art. With focus on problems of specific weapons identity and interpretation of weapon as feature AUTHOR: Tomáš Schartel DEPARTMENT: Institute for professional development, faculty of education SUPERVISOR: Mgr. Ondřej Sýkora ABSTRACT: The purpose of this bachelory diploma is to present a weapon as a mean of hunting or fighting, as well as the masterpiece, which says a lot about a person who created it. The creator gave to each weapon himself, didn't he? He had to be a good craftsman but he had to have art feeling too. Some people said the weapon had a magic power, according to others it wasn't difficult to recognize their owner. A long time ago the typical weapon was a sword which the kings and knights used to show their power. The sword as the most important weapon of medieval fighter, was very efficient and it was used for fighting at close range. The sword wasn't only the symbol of war but also the sign of prior role in society. But we can't only see the sword as a weapon. Sovereigners handed over the sword to each other as a symbol of reign leaving. The sword was a symbol of faith at the time of crusade when its shape was taken as a cross. The contribution of the bachelory diploma is acquisition of basic knowledges from the history of development and establishment the variety...

Felis versus Felix - Symbolic and narative content (of Cat) in Art and Art education
Pikorová, Karolína ; Velíšek, Martin (advisor) ; Raudenský, Martin (referee)
The theme of this diploma thesis is Felis versus Felix - symbolical and narrative content within art and arts education. This thesis is both theoretical and practical study of the topic. Theoretical part is concerned with understanding key words, their meaning, cat itself, its symbolic, history, properties, and connotations connected to it. The author of the thesis maps the occurrence of cat in art and literature, which she supports by specific examples. She further offers using the theme of the thesis in arts education and introduces already existing art set called "Animal within us". The author proposes another possibilities of using the theme within pedagogical practise. Practical part of the thesis stems from results of heuristic preparation. It contains two sets of art works of various but interconnected nature.

Comparison of Narrative Methods in Features Published by Respekt and New Yorker
Janauerová, Barbora ; Hájek, Roman (advisor) ; Krobová, Tereza (referee)
The aim of this thesis is to analyse narrative strategies in the texts of the feature genre in two periodicals. Feature genre is longer genre of journalistic (opinion) character regularly used in printed world media, especially magazines. It is a genre which combines elements of two genres - report and analytical article. This thesis compares features in Czech and American environment, the latter being a more tradiotional for the genre. The two periodicals in question are Respekt and New Yorker. The choice is influenced by the fact that the chief editor of Respekt claims the medium to be inspired by New Yorker. The research method of the work is narrative analysis. Analysed categories are then narrator, focalization, description of a character and a alternating of the report and contextual parts of the feature genre. An important part of the work is analysis of intentionality of the use of certain type of narrators and focalization. Some of the narrative strategies, types of narrators and focalization used in the context of the journalistic texts influence the degree of objectivity/subjectivity of the narrative. Through analysis the comparison of the feature genre in Czech and Anglo-American journals is made, how they differ and what they have in common.

Detection and Vizualization of Features in a Point Cloud
Kratochvíl, Jiří Jaroslav ; Mikeš, Josef (referee) ; Martišek, Dalibor (referee) ; Procházková, Jana (advisor)
The point cloud is an unorganized set of points with 3D coordinates (x, y, z) which represents a real object. These point clouds are acquired by the technology called 3D scanning. This scanning technique can be done by various methods, such as LIDAR (Light Detection And Ranging) or by utilizing recently developed 3D scanners. Point clouds can be therefore used in various applications, such as mechanical or reverse engineering, rapid prototyping, biology, nuclear physics or virtual reality. Therefore in this doctoral Ph.D. thesis, I focus on feature detection and visualization in a point cloud. These features represent parts of the object that can be described by the well--known mathematical model (lines, planes, helices etc.). The points on the sharp edges are especialy problematic for commonly used methods. Therefore, I focus on detection of these problematic points. This doctoral Ph.D. thesis presents a new algorithm for precise detection of these problematic points. Visualization of these points is done by a modified curve fitting algoritm with a new weight function that leads to better results. Each of the proposed methods were tested on real data sets and compared with contemporary published methods.
