Editorial stručně shrnuje obsah monotematického čísla, v němž jde o teoretické představení pěti přístupů k analýze argumentačního textu (neoaristotelský přístup, Toulminův model, přístup neformální logiky, pragma-dialektiky a kritické diskurzivní analýzy) a o ilustraci prostřednictvím aplikací těchto přístupů na konkrétní materiál. Ve všech textech čísla je jako společný materiál pro analýzu zvolen videoklip Přemluv bábu (2010). Editorial nabízí představení videa: jeho přepis, historický kontext a zhodnocení dosavadních pohledů na jeho přesvědčivost.

Aim of the thesis is to design and implement unique service based on the newest technologies in web apps fi eld which allows screen recording followed by P2P distribution between participating users using web browser only. Thesis deals with the analysis of modern and coming technologies which allow practical implementation of such a service. It involves obtaining access to the screen source data, its recording, transforming and transmission over the network followed by playing on the other side. Recorded videos are adapted for part by part use in a player with seeking capability. Distributed architecture for data exchange between peers using peer-to-peer connection based on hybrid P2P VoD network provides scalability of the solution. The player allows obtaining the necessary parts of the videos from the current watchers with smooth video playback experience during ongoing transmissions whilst allowing arbitrary video shifting. In consideration of early stages of development or experimental support for some of the APIs needed for this work, research into browsers' support with discussion on realistic applicability nowadays is always performed.

The aim of this diploma thesis is to create a practical solution for individual athletes in the form of a digital mirror, which can become an alternative to observing yourself in an ordinary mirror. The work contains and emphasizes the benefits of a digital mirror. Much of the work is devoted to the transfer of video between various devices for the ability to combine multiple videos on a single screen. The core of the solution is a mobile application for the Android platform, which works in various modes, the choice of which depends on how the application is used. The application was continuously tested with a group of users, resulting in iterative improvements to the application's features and the addition of new features. Furthermore, a web variant of the application was implemented, which increases the possibility of using the digital mirror across different platforms. The results of testing show that this whole solution can be used in the practical training of sports exercises and the application has the potential to connect with various sports.

Key tasks of this work are to create the simulation of a wireless network in ns-3 and to stream a video over this network by using MPEG-DASH technology. It describes the tools and methods how to encode a video according to MPEG-DASH. It is explained what is needed to run video server, which uses MPEG-DASH technology to stream videos. Then, it is described how a simulation of wired and wireless WiFi and LTE networks is created. The simulation starts a server and shows how it works, how many nodes can be used and chooses suitable segment duration.

This masters thesis is focused around the comparison of time dependent video grayscale conversion methods based on a user experiment. The test methodology is based on the pairwise comparison method 2AFC. It is composed of two test variants: a test with a reference video and a test without a reference video. The coefficients of agreement, consistency and correlation are utilized in the result analysis. The testing was done on 60 subjects which have done 7200 pairwise comparisons. The test results show that the time dependent method Hu14 is the most universal. Time dependent method Kim09 was bested by some non-dependent methods. The results also indicate that there is some correlation between the two test variants and that the choice of the input video can have impact on the method performance. The main contribution of this thesis is that non-dependent methods can under certain circumstances rival the performance of dependent methods and that the addition of a reference video did not have a meaningful impact on the test subjects judgements.

This project deals with a web-based lecture browser, whose goal is to simplify the gaining of knowledge with the use of multimedia. It presents an existing lecture browser that was created for a diploma thesis at FIT VUT Brno. Demonstrated are the technologies that are used and which will be used to migrate the browser to a MySQL database and to develop a transcription module for speeches. The reader will be acquainted with an analysis and model of the new application. Furthermore, implementation methods for development and subsequent testing are discussed. At the end of the project is a conclusion about the future development of web-based lecture browsers.

The diploma thesis discusses the phenomenon of tutorials uploaded on the most visited server for viewing and sharing video content nowadays - YouTube. The term tutorial here is used for referring to the specific instructional video content, which primarily aims to show, by means of the step by step illustration, how to proceed within particular activity that usually requires to adopt a certain extent of specialized knowledge or skills. At the same time, the attention is focused on the graphic design and fine art tutorials. The main goal of the thesis is to answer following question: what motivations might internet users have both for the reception and for the production of tutorials. In other words, the thesis is oriented on searching for the highest possible amount of motives that can lead to the viewing as well as to the shooting of this specific media content. Therefore, this requires examining a given field from two different perspectives: from the perspective of receiving viewers and from the perspective of video makers. Whole thesis structure is then subordinated to these two perspectives. The first part introduces the relevant theoretical approaches related to the tutorial reception/production, whereas the second practical part is devoted to the presentation of particular motivation...

Title: Image Deblurring in Demanding Conditions Author: Jan Kotera Department: Institute of Information Theory and Automation, Czech Academy of Sciences Supervisor: Doc. Ing. Filip Šroubek, Ph.D., DSc., Institute of Information Theory and Automation, Czech Academy of Sciences Abstract: Image deblurring is a computer vision task consisting of removing blur from image, the objective is to recover the sharp image corresponding to the blurred input. If the nature and shape of the blur is unknown and must be estimated from the input image, image deblurring is called blind and naturally presents a more difficult problem. This thesis focuses on two primary topics related to blind image deblurring. In the first part we work with the standard image deblurring based on the common convolution blur model and present a method of increasing robustness of the deblur- ring to phenomena violating the linear acquisition model, such as for example inten- sity clipping caused by sensor saturation in overexposed pixels. If not properly taken care of, these effects significantly decrease accuracy of the blur estimation and visual quality of the restored image. Rather than tailoring the deblurring method explicitly for each particular type of acquisition model violation we present a general approach based on flexible automatic...
