Eyetracking for traffic analysis
Veselá, Cindy ; Němcová, Andrea (referee) ; Janoušek, Oto (advisor)
This bachelor thesis deals with the analysis of eye movement during solving traffic situations using eyetracker. The theoretical part describes eye anatomy and the types eye movement. It also explains methods of how eye movement is tracked with a focus on eye-tracking methods. Practical part contains two programs and record of eye movement of drivers. The first program records eye movement during traffic observation in videos, the second program visualizes eye movement in displayed videos. It was examined parameters of eye movement, which could lead to differentiation of drivers according to their experience.

Program for deinterlacing in video sequences of different formats
Jirků, Pavel ; Kratochvíl, Tomáš (referee) ; Slanina, Martin (advisor)
The aim of this thesis is a study of advanced algorithms for removing interlacing in digital video sequences. The first part of the work is devoted to the theory, basic knowledge and processing characteristics using multimedia data. The second part is devoted to displaying the signal using interlaced and progressive spacing. The following part is focused on methods of conversion between the interlaced line spacing and progressive spacing. The last part deals with implementation of the proposed methods. The algorithm is implemented in C++ language, which provides sufficiently fast processing algorithms. The conclusion of work is focused in testing and verification of the implemented algorithms.

Monitoring of Solder Spreading Velocity on Metal Surface
Růžička, Miroslav ; Dušek,, Karel (referee) ; Starý, Jiří (advisor)
This work deals with flushing monitoring of spreading velocity on solder finishes Niau, OSP, Sn deposited on copper plated base material FR4 using digital cameras. After the reflow process is measured by length of spreading solder and size of wetting angle. It evaluates and compares the time dependence of velocity of spreading solder, length of solder spreading and wetting angle for NiAu, OSP, Sn finishes at different temperatures reflow and surface treatment.

Face recognition
Maňkoš, Richard ; Mézl, Martin (referee) ; Kolář, Radim (advisor)
This diploma thesis deals with face recognition in digital pictures. The first part describes biometry and, shortly, characterizes biometrical methods which are the most oftenly used. In the second part is described the approach of face recognition in a picture. Specifically, it is described the method for face detection - Viola-Jones and method for face recognition - PCA, which will be implemented in Matlab. The last part, which is practical, describes the scheme for video-sequence recording, implementation of the PCA method in Matlab and discussion of the achieved results.

Decomposition of video-sequences into components with different dynamics
Gebrtová, Karolína ; Druckmüller, Miloslav (referee) ; Rajmic, Pavel (advisor)
The thesis is focused on the decomposition of video sequences, primarily on background and dynamic component separation, where the background remains the same and only small parts are in motion. Such a video is represented by a low-rank and sparse component. Thanks to the low-rank structure, the background can be separated using a median filter and dynamic mode decomposition. Furthermore, the robust principal component analysis, formulated as an optimization problem and its non-convex variant, will be employed. Also mentioned will be the multiresolution DMD, which is capable of decomposing the dynamic component based on its velocity.

Anomaly detection in video sequences on devices with low computing power
Bílek, František ; Ježek, Štěpán (referee) ; Sikora, Pavel (advisor)
The bachelor’s thesis focuses on the problem of anomaly detection in video sequences on devices with low computational power. Traditional and current approaches to anomaly detection are described from the perspective of machine learning and neural networks. The goal of the thesis is to implement an efficient and reliable algorithm capable of detecting anomalies in real-time. Emphasis is placed on minimizing computational requirements and optimizing memory usage to achieve efficiency on devices with limited computational capacities.

The use of movie scenes in teaching physics
BURDOVÁ, Veronika
The aim of the thesis is selection, physical analysis and didactic analysis of scenes of the most famous mainly Czech movies. The movie scenes are chosen according to Framework Education Programme for Elementary Education and for Secundary General Education. Their didactic analysis is composed of inclusion in teaching, methodical analysis of the movie scenes and feedback.The didactic analysis was developer during whole school year at the grammar school. In the conclusion of the thesis there are three pedagogical studies focused on effectiveness of teaching consisting video-sequences, motivation of students and knowledge of movies from work.
