Web App for Image and Video Quality Assessment
Píč, Karel ; Bobák, Petr (referee) ; Čadík, Martin (advisor)
This work will be a web application for image and video quality assessment, especially those with a high dynamic range (HDR). The metrics are used for the evaluation, the results of which will be used for scientific purposes. Broader public citizens will be acquainted with this issue. This app will have an assistant available for a simple understanding of the whole application. The application also tries to be autonomous and dynamic. For example, new metrics can be added from the administration environment and editing on the server side is not required. The administrator will be able to upload a metric, a local library, a startup script, and define the parameters. The parameters provide metrics necessary data from the processed image or video. Only installation of system applications and libraries will be required on the server side.

Polygonal Models Smoothing
Nečas, Ondřej ; Herout, Adam (referee) ; Kršek, Přemysl (advisor)
The result of digitalization 3d surface is affected by many factors. After digitalization can on the surface emerge some unwanted artefacts. The differences from original are caused by resolution of the device or its limited precision. For elimination of this artefact exists many smoothing algorithms, but we want to choose that which best suits this purpose. So it is useful to know their limits and characteristics.

Information System Design
Pisarčíková, Michaela ; Biolek, Jaroslav (referee) ; Koch, Miloš (advisor)
The master’s thesis deals with the design of a management information system, which is represented by a set of dashboards and reports. The main purpose of the system is to provide technological and information support to the management of company in terms of managing strategic goals and business performance. The information obtained by analyzing the company and its surroundings are subsequently used for draft creation. The thesis draft contains a project plan for the design and implementation of the system, the design of the system itself - its content and technical aspects, furthermore, we also deal with the implementation of the system and the management of this change.

Evaluation and design of performance reporting
Tichý, Tomáš ; Koch, Miloš (referee) ; Novák, Lukáš (advisor)
The aim of the thesis is to analyze the functioning of reporting of the selected department in the company ABB s.r.o. Based on the findings of the analytical part, a number of new reports on the performance of the selected department in the company and appropriate metrics are proposed. The implementation of these reports helps the company to predict the possibility of delays and also offers possible solutions to avoid this potential problem.

Security analysis of network traffic using behavioral signatures
Barabas, Maroš ; Hujňák,, Petr (referee) ; Zelinka,, Ivan (referee) ; Hanáček, Petr (advisor)
This thesis focuses on description of the current state of research in the detection of network attacks and subsequently on the improvement of detection capabilities of specific attacks by establishing a formal definition of network metrics. These metrics approximate the progress of network connection and create a signature, based on behavioral characteristics of the analyzed connection. The aim of this work is not the prevention of ongoing attacks, or the response to these attacks. The emphasis is on the analysis of connections to maximize information obtained and definition of the basis of detection system that can minimize the size of data collected from the network, leaving the most important information for subsequent analysis. The main goal of this work is to create the concept of the detection system by using defined metrics for reduction of the network traffic to signatures with an emphasis on the behavioral aspects of the communication. Another goal is to increase the autonomy of the detection system by developing an expert knowledge of honeypot system, with the condition of independence to the technological aspects of analyzed data (e.g. encryption, protocols used, technology and environment). Defining the concept of honeypot system's expert knowledge in the role of the teacher of classification algorithms creates autonomy of the~system for the detection of unknown attacks. This concept also provides the possibility of independent learning (with no human intervention) based on the knowledge collected from attacks on these systems. The thesis describes the process of creating laboratory environment and experiments with the defined network connection signature using collected data and downloaded test database. The results are compared with the state of the art of the network detection systems and the benefits of the proposed approximation methods are highlighted.

Efficient Application of SCRUM Methodology in a Development Team
Svoboda, Radek ; Kalouda, Petr (referee) ; Smolíková, Lenka (advisor)
The master thesis focuses on more efficient application of Scrum methodology in a development team within specific company. The thesis takes an advantage from the SW-CMM philosophy applied in agile environment in order to achieve better effectivity. Theorethical base is utilized for a comparison with current state in the company described in analytical part. Proposals for a solution of current situation are based on drawback detection. Proposals are subject for risk analysis followed by precaution. Costs of proposals implementation with included precautions are evaluated in economic evaluation part. This part also contains benefits of proposals.

Source Code Metrics for Quality in Java
Sherstobitov, Vladyslav ; Dvořák, Tomáš (referee) ; Křivka, Zbyněk (advisor)
Pro kontrolu a zlepšovaní kvality zdrojového kódu musí být zaveden systém, který se skládá z kvantitativních metrik a jejich analýzy. S použitím metrik kvality softwaru, které reprezentují, jak dobře je zdrojový kód napsán, lze hodnotit zdrojový kód. Na základě tohoto hodnocení může kód splňovat nebo nesplňovat stanovená kritéria, která mohou být použita pro mnohá účely. Daný výzkum prezentuje program vyvinutý na základě identifikovaných vlastností kódu a souvisejících metrik, metod používaných při tvorbě programu a výsledků testů založených na projektech s otevřeným zdrojovým kódem.

Source Code Metrics for Quality in Java
Sherstobitov, Vladyslav ; Burget, Radek (referee) ; Křivka, Zbyněk (advisor)
Aby bylo možné kontrolovat a zlepšovat kvalitu kódu, musí být zaveden systém, který se skládá z kvantitavních metrik a jejich analýzy. S použitím metrik kvality softwaru, které nejlépe reprezentují, jak dobře je zdrojový kód napsán, lze hodnotit zdrojový kód. Na základě tohoto hodnocení může kód splňovat nebo nesplňovat stanovená kritéria, která mohou být použita pro mnohé účely. Daný výzkum prezentuje program vyvinutý na základě identifikovaných vlastností kódu a souvisejících metrik, metod používaných při tvorbě programu a výsledků testů založených na open-source projektech.

Compression and analysis of digital video signals
Grúbel, Michal ; Slanina, Martin (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor's thesis deals with technical parameters of chosen algorithms for video compression, especially MPEG-1, MPEG-2, MPEG-4 Part 14 and DivX. Whitin it there was created a special software in Matlab that compares frames differences between reference and evaluated sequence. For this purpose there were recorded short test sequences with different properties in time and frequency domain, which recording, compressing, decompressing and decompiling to single frames are described and shown in detail. The results of evaluation are processed in graphs and then described in writing. In final overall evaluation is stated which algorithm for video compression is optimal for which type of sequences that differ in properties in time and frequency domain.
