Visual Anomaly Detection in Industrial Production
Hrabica, Jan ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
This thesis deals with the problem of unary classifiers for anomaly detection in industrial production. It starts with a discussion of classification as a general problem, classification methods and some of their evaluations, and then discusses the main categories of architectures used. Practical part describes the process of scene creation for the acquisitions of a datesed. Acquired dataset is then used for teaching a classifier, on which is then performer a number of experiments to determine its performance.

Stereo reconstruction of vehicles' cross section
Boch, Jan ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This master thesis deals with the design of a stereo system for processing vehicle images and subsequent reconstruction of their 3D model. The aim of the thesis is to reconstruct the vehicle model to control its dimensions and load on which restrictions are imposed in case of the use of critical transport infrastructure (tunnels, bridges). The thesis begins with a mathematical description of scene capture and continues with a research of theoretical possibilities of system configuration. One Intel RealSense 3D camera and one RGB camera were chosen as the most suitable configuration. The software solution works with the design of several different algorithms of which it is worth mentioning reconstruction using depth maps or triangulation.The resulting models in the last chapter contain data only from the aforementioned 3D camera. The model from the 3D camera could not be improved with the images from the RGB camera and camera can therefore be declared redundant. Resulting 3D model is still sufficient for the purpose of vehicle inspection and in case of continued work, another, more optimal configuration should be designed.

Investment Life Insurance and Individual Investments Connected with Insurance
Richter, Jan ; Jál, Lukáš (referee) ; Ptáček, Roman (advisor)
This diploma thesis deals with the comparison of investment life insurance with risk life insurance and individual investment in open mutual funds in the territory of the Czech Republic. The theoretical part describes the basic characteristics of life insurance, open mutual funds and as a cross-section of the two products of the investment life insurance. It also describes the main cost indicators that can be used to calculate the cost of the insurance product. The analysis of the current situation is focused on a model example, in which the insurance products are compared and the investment part is evaluated. Subsequent comparison of results, selection of the most effective tool and recommendations are contained in the proposal section. The main goal of the diploma thesis is to determine the best solution for the end customer and to propose possible changes in the investment life insurance to make it more competitive.

Temperature control
Soviš, Jiří ; Glos, Jan (referee) ; Richter, Miloslav (advisor)
The thesis deals with the issue of temperature control by means of an uncontrolled source of waste heat in a closed room. The main purpose of this thesis is to get acquainted with problematics and technology used in the field of HVAC. Part of the thesis is a solution design of temperature control in which the heat loss from the compressor is used to heat the compressor room and as a supplementary heat source to the production hall to reduce costs. As part of the algorithm solution, was created a temperature model, developed in Matlab / Simulink, which was used to design a PI controller using integral quality control criterion ITAE and Nelder-Mead simplex.

Track detection and planning
Brázdil, Jan ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
The goal of the thesis was to design and create a line follower with one-line camera on The Freescale Cup 2013 car model platform. Computational unit is microcontroller Kinetis K40, which receives data from camera and other sensors. Then use these inputs to calculate the ideal path. This bachelor thesis leads to test several different types of controlling in unknown environment – data table control, vector control and PSD controller. It then expolores in known environment – map creation and drive control with map data. The thesis describes all used components, control theory and creating and programming controllers. In conclusion of this thesis all algoritms are tested on real track and results are compared.

Distributed Brute Force Attacks Protection
Richter, Jan ; Čejka, Rudolf (referee) ; Lampa, Petr (advisor)
This project deals with analysis of brute force attacks focused on breaking authentication of common services (especially ssh) of Linux and xBSD operating systems. It also examines real attacks, actual tools and ways of detection of theese attacks. Finaly there are designed new mechanisms of coordination and evaluation of distributed brute force attacks in distributed environment. These mechanisms are then implemented in distributed system called DBFAP.

3D model
Krátký, Martin ; Klečka, Jan (referee) ; Richter, Miloslav (advisor)
The aim of this bachelor thesis is to create a spatial model from images capturing an object illuminated by a laser pattern. The thesis presents possible solutions to the problem using methods of active triangulation and stereoscopy. Methods are designed for laboratory and outdoor measurements. The requirements for the measuring workplace are defined and then the implemented workplace is presented. Each of the designed methods is tested by scanning a series of objects.

Automated optical measurement of drops contact angle
Dugáček, Ján ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
Measurement of surface tension of solids usually requires manual processing of photographs of droplets of liquids with known properties on the measured material's surface, during which the contact angle is manually determined. The objective of this work is to implement an algorithm that can determine these contact angles from photographs and does not require the photographs to be made under specific light conditions. The implementation cannot depend on paid libraries and must be simple to incorporate into existing software.

Defects classification
Benda, Jan ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
The thesis deals with a concept and creation of classifiers of defects found on continuous production lines. The first part presents an overview of methods used for image classification and a analysis of defects. The main part of the thesis consist of a description of created classifier interface and graphical user interface for classifier. The last part sums up reliability of each implemented classifer.

Path monitoring
Sedlařík, Jan ; Janáková, Ilona (referee) ; Richter, Miloslav (advisor)
This bachelor's thesis deals with path monitoring theme. To successful accomplishment of this task it is right to have the high-quality videos. It is imperative to concentrate to their correct scanning and preprocessing. Detection of objects and their monitoring are one of the most elementary parts of the challenge. Important part of image separation is edge detection.
