Automatic positioning of the rear view mirror
Návara, Marek ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This thesis solves design of functional device that will be able to automatically positioning back view mirrors according to the positio of driver face. Measuring position of the face provides stereovision of two webacams. The device is based on a computer Raspberry Pi 2 with designed expansion board. The created prototype can follow set view int the mirror with accuracy up to 7 cm (horizontally up to 5cm) in level of rear corner of a car. The results of this project validate design of automatic positioning mirror and it can be basis for specific implementations of the device in car.

Human-Computer Interaction with Laser Pointer
Pavlín, Václav ; Ševcovic, Jiří (referee) ; Šolony, Marek (advisor)
This bachelor's thesis deals with the design and implementation of a system for controlling a PC via a laser pointer on a projection screen. Using a laser pointer can completely replace a computer mouse. The system simulates mouse cursor movements and clicks. The application uses homography for automatic camera calibration as well as for the conversion of coordinates between the image on the projection screen and the image on the computer.

Camera based eye tracking
Otáhal, Miroslav ; Walek, Petr (referee) ; Janoušek, Oto (advisor)
The aim of this master thesis is to understand problematic of eyes movement tracking using webcam. In individual chapters there are introduced basic approaches of eyes movement tracking, based on this method we can get the position of eye pupil and identify where a person looks. The part of this work is program in Matlab, which using the method of infrared detection follow the position of eye pupil and transfer this movements to the movements on the computer screen. Using this program it was tested several volunteers and the results of detection were transferred to the visual form. As part of this program it was created template for assessment of accuracy of used method. At the end of work are discussed achieved results.

Stereoscopic sensor for distance measurement
Vavroš, Ondřej ; Hasmanda, Martin (referee) ; Říha, Kamil (advisor)
This master's thesis will take us through theoretical procedure that allows us to determine the distance of an object by stereoscopic sensor. Part of this work presents the description of the steps to achieve image of objects, calibraton and rectification. At the next part our study provides an overview of algortihms for creating disparity maps and determining the distance of the object from sensor. In the following part of thesis deals with the implementation of these processes into aplication which aim is to measure the distance.

Special security system
Náhlík, Ondřej ; Masopust, Jiří (referee) ; Hanus, Stanislav (advisor)
This master’s thesis is focused on design and realisation of special security system for space and property protection. System is devided into two parts, transmitting and receiving. Transmitting part is formed by Raspberry Pi Model B+, motion sensor, webcam and USB LTE modem Huawei E398. Receiving part consists of computer with suitable application for communication with FTP server. Data transfer in mobile systems is described in the first part of this thesis, transmitting part is designed in the second part. There is one transmitting option chosen in the third part and there are also described applications of the transmitting part. The last part of this thesis is focused on the receiving part and its application.

Web applications for user authentication
Vybíral, Petr ; Dzurenda, Petr (referee) ; Hajný, Jan (advisor)
The thesis deals with the problems of user authentication. The first chapter analyzes the problem of authentication, its methods and its utilization. The second chapter presents the different security options for communication. The chapter describes security, communication and authentication protocols. There is the 2D barcode QR Code described at the end of the chapter. The third chapter is devoted to ASP.NET technology, its development and possibilities of utilization. Attention is focused on web form and server controls. There is an analysis of elements of cookies and possibilities of their use. The last chapter consists of a practical part, which describes the development of a web application. There is a description of the parts of application, such as the database, the Web navigation, master pages and etc. in the following chapter. The cardinal part of the chapter consists of an analysis and implementation of forms authentication, the attribute authentication and authentication with QR code. Finally, there is a description of way how to secure the communication by using a certificate.

Eye tracking
Magula, Filip ; Rajmic, Pavel (referee) ; Vlach, Jan (advisor)
This work deals with tracing the eyes in real-time video using infrared radiation treatment and detection of its rebound on pupils. It describes the human eye and its response to infrared radiation. It contains proposals for hardware and software solutions and the final realization of the basic options in Simulink, explains the selected methods of digital image processing and includes an assessment of the methods used in this work in conclusion.

HTML5, getUserMedia and its use with camera
HEJTMÁNEK, Lukáš
The AIM of this thesis is the current analysis of the development of new method getUserMedia in web browser, which is a part of HTML5. This technology enables the website to approach to the webcam or microphone. In the past this was possible only via using of plugins, which had to be installed. Nowadays mainly Adobe Flash belongs to these plugins. This thesis deals with advantages and disadvantages of this new technology against other technologies enabling to approach to the webcam. There will be carried out testing of support of this new technology in available versions of browsers either desktop or mobile (smartphones/tablets). As a practical part of my work I will create a set of examples, which will be available on the Internet. The main practical example will be a creation of a simple web application enabling videoconferencing using getUserMedia and third-party frameworks.
