Figure trracking
Berka, Jiří Michael ; Řičánek, Dominik (referee) ; Richter, Miloslav (advisor)
This bachelor's thesis focuses on the development of software for tracking an exercising person and evaluating deviations from the correct execution of movement tasks. Initially, the thesis theoretically examines the fundamentals of digital image processing, the use of various types of cameras, and computer vision technologies. Subsequently, methods of artificial intelligence and deep learning that enable motion detection and analysis are described. The main part of the thesis focuses on the implementation of the OpenPose system for real-time pose estimation. Technical challenges are discussed, and solutions are proposed to achieve the accuracy and reliability of the system. The practical part includes testing the software on real videos and evaluating its performance. The results show that the developed software can effectively help in correcting movements and preventing injuries in various applications.

Analysis of Motion of People by a Stationary Camera
Smatana, Stanislav ; Juránková, Markéta (referee) ; Herout, Adam (advisor)
Hlavním cílem této práce bylo navrhnout a vytvořit systém sledování osob s aplikací v oboru bezpečnosti nebo pro analýzu chování zákazníka v obchodě. Systém byl úspěšně implementován pomocí metod KLT trekování, AdaBoost klasifikátoru a datové asociace pomocí Markovských řetězců a metody Monte Carlo. Implementace umožňuje analýzu pohybu lidí ve vnitřních i vnějších prostorech.

Swimming analysis using a SwIMU measuring device
Láznička, Jakub ; Šťastný, Jan (referee) ; Bátorová, Michaela (advisor)
This bachelor thesis deals with the description of the inertial sensor for measuring swimmers.The work contains a description of the possibility of performing swimming performance analyzes. In the practical part, a pilot measurement was performed and a detailed manual was created containing a description of accessories, the measurement process and the methodology of subsequent evaluation. An external database in MS Excel was created to compare the evaluated measurements, used to sort data with the possibility of statistical processing.

Measuring unit for race swimmers motion analysis
Kumpán, Pavel ; Hrbáček, Jan (referee) ; Krejsa, Jiří (advisor)
The master’s thesis deals with a design of the computational method for the analysis of swimmers training with the use of an inertial measurement unit. The developed algorithm uses quaternion-based Unscented Kalman filter and merges accelerometer and gyroscope measurements. The proposed method enables analysis of velocity, acceleration and inclination of a swimmer. Verification of the method was based on an underwater video camera capturing and a tethered velocity meter.

Measuring of Vehicle Instant Velocity
Štencel, Jakub ; Petyovský, Petr (referee) ; Horák, Karel (advisor)
The theoretical part of this paper summarizes the methods for motion analysis in an image. Inspected in detail are the methods used for motion detection in the image sequences. The practical part is focused on finding the significant points in the image (the targeting reticles on the body of the vehicle) which are then used to calculate the speed of the vehicle.

Robust Detection of Moving Objects in Video
Klicnar, Lukáš ; Herout, Adam (referee) ; Beran, Vítězslav (advisor)
Motion segmentation is an important process for separating moving objects from the background. Common methods usually assume fixed camera, other approaches exist as well, but they are usually very computational intensive. This work presents an approach for scene segmentation to regions with coherent motion, which works faster than similar methods and it is capable of online processing with no prior knowledge of objects or camera. The main assumption is that the points belonging to a single objects are moving together and this applies as well in the opposite direction. The proposed method is based on tracking of feature points and searching for groups with similar motion by using RANSAC-based algorithm. Short-range repair of broken tracks is applied to increase the overall robustness of tracking. Found clusters are subsequently processed to represent separate moving objects.

Interest Points Tracking in Video Sequence of Non-stationary Camera
Studený, Pavel ; Davídek, Daniel (referee) ; Horák, Karel (advisor)
The thesis deals with the issue of tracking feature points earned from videosequences of hand helded camera. The work is focused on the case of moving camera and static background, and events that are associated with this case and can occur. There is studied the movement of the camera, which is given its direction and speed. The aim of this work is the election and the subsequent implementation of three fundamentally different methods suitable for tracking feature points in case of moving camera and their comparison according to set criteria. On the basis of comparison will be under pre-defined conditions chosen algorithm that is best able to deal with tracing these points.

Development of equipment for body posture analysis
Vančura, Lukáš ; Krejčí, Petr (referee) ; Pillet,, Helene (advisor)
Zařízení k analýze pohybu umožnují zdokonalit chirurgický zákrok, rahebilitaci patologií pohybového systému a jsou také velmi přínosné pro výzkum v oboru biomechaniky. V dešní době existuje mnoho zařízení k analýze pohybu, jejihž cena může dosáhnout až 150 k€ (Vicon, Motion Analysis). Cílem této diplomové práce je vyvinutí levného prototypu zařízení k analýze pohybu založeného na sledování barevných terčíků pomocí dvou jedoduchých digitálních kamer a programu ke zpracování obrazu.
