Recognizing and Classification of Traffic Situations
Zbořil, Jiří ; Musil, Petr (referee) ; Smrž, Pavel (advisor)
The aim of this thesis is to identify and classify dangerous situations from surveillance cameras, monitoring traffic. An example of such situations is dangerous standing near by the road and car crash, on which this work focuses. The created system uses object detector, analyzing average images in given interval, K nearest neighbor and K Means algorithm and re-detection of enlarged local area in a frame to select anomaly candidates. Detected objects, that do not belong on the road are eliminated by attaching created road mask. At the very last phase, the interval, together with the classification is determined. Calculated F1 score is 0.645, S4 score 0.535 and precision of classification 80 %.

Comparison of technologies for vehicle passage detection
Mareková, Martina ; Frolka, Jakub (referee) ; Krajsa, Ondřej (advisor)
System for vehicle detection and speed measurement system is an important part in traffic control as well as in providing data for intelligent and automated traffic signs. These technologies are divided into two types: intrusive and non-intrusive methods. Traditional traffic control is based on inductive loops. This method is intrusive and therefore requires intervention under the road and higher maintenance requirements. We can avoid this problem with non-intrusive methods, including video analysis, microwave radars, geomagnetic radars, weighing sensors and laser sensors, but these are more expensive alternatives. By implementing radars we performed measurements on road sections, on the basis of which the output data from microwave, weigh-in-motion sensors and induction loops were displayed. We receive processed and unprocessed output data of measurements from each sensors. For processing of those data is created software solution for graph rendering and direct measurement of the sensor accuracy in comparison with competing technology. The results of the measurements showed that the efficiency of the individually implemented sensors is sufficient for use in traffic control. As well we can consider the implementation of microwave radars and cameras for video analysis as a replacement for the conventional method of induction loops.

Characteristics of Men's professional volleyball league in terms of technical-tactical aspects of the sport
Svobodová, Iveta ; Buchtel, Jaroslav (advisor) ; Kočíb, Tomáš (referee)
Title: Characteristics of Men's professional volleyball league in terms of technical-tactical aspects of the sport. Objectives: The main objective was to determine which final game activities led to the selected teams obtaining a point and to determine the ratio of final game activities in their triumphant sets. The selected matches were played at the 2015 Men's European Volleyball Championship. The next objective was to compare the selected teams with each other. Methods: In order to meet the objectives, video recordings of played matches were analysed and scores were tallied and compared across all selected teams. Tallying of scores was applied to all video recordings of selected plays in which four teams were analysed in total. The frequency method was used in order to detect which final game activities led to winning of the ball. The comparison method was later used for comparing the selected teams with each other. Results: In detected ratios of final game activities that led the teams to obtain a point we can see the deviations from the average (attack 60%, opponent errors 24%). We found out that the gratest amount of points gained was due to the attacks and opponent errors. We can confirm the trend of top league teams showing the gratest amount of points won due to the attack from the quick...

Athletic physical literacy of secondary school pupils
Vitovský, Radek ; Vindušková, Jitka (advisor) ; Jebavý, Radim (referee)
Title: Athletic physical literacy of secondary school pupils Objectives: The aim of this thesis was to compare athletic literacy of seventh and ninth-graders and to test if these pupils are able to perform athletic excercises and can be therefore called athletically literate. Methods: Cross-sectional study, video analysis. Results: The final evaluation showed that the results of both tested grades in the nodal points are similar. Both groups have comparable athletic skills, however, the ninth-graders reached slightly better results. These pupils have more experience and they were able to coordiate their movements better and their performance was also smoother. This "extra" ability is what can be called athletic literacy. The pupils have basic athletic skills and they also know how and when to use these skills properly. Keywords: Athletic literacy, video analysis, kinogram. pupils

Time characteristics of workload during climbing the same route on a climbing wall and treadwall
Maťochová, Šárka ; Baláš, Jiří (advisor) ; Gajdošík, Jan (referee)
Title: Time characteristics of the load when climbing the same path on an artificial wall and on a climbing ergometer Objectives: The aim of this work was to assess the time characteristics of the grip when climbing on a climbing wall and on climbing ergometer and to compare these results. Methods: Twenty female participants were divided according to their performance into two groups. Two identical routes were climbed- one on a climbing ergometer, the other on an artificial climbing wall. Climbing routes were 18 m long and were rated Grade 7 on the IRCRA scale. There were 45 grips used in total, the starting hand grip was 1.5 m above the ground. The profile of the climbed route was perpendicular (90 ř). The task was to climb the route in the specified time. Data were collected by making a video recording of the movement on the climbing wall and the climbing ergometer. To determine the time characteristics, video recordings were analyzed in Dartfish 10 software and the duration of the static and dynamic phases were assessed. Results: The total time of climbing on the ergometer was 258.0 ± 16.1 s for less advanced, 263.8 ± 4.4 s for more advanced. The total time for wall climbing was 273.4 ± 22.9 s in the less advanced group and 259.5 ± 18.4 s in the more advanced group. The mean time of static...

The evaluation of a tennis groundstroke by qualitative examination of functional movement
Vojtěchovská, Karolína ; Oplatková, Lenka (advisor) ; Kolář, Jáchym (referee)
This bachelor's thesis describes the evaluation of the tennis groundstroke and the influence of postural stabilization on the resulting quality of activation of the trunk in the groundstroke. The theoretical part summarises the knowledge of the optimal performance of the forehand, as well as the method of evaluating the forehand. In the practical part of the bachelor's thesis, we qualitatively assessed postural stabilization of players according to the concept of DNS. We followed the process of qualitative movement diagnosis and we performer video analysis of the forehand from the Slow-motion recording. The specific parameters of the tennis groundstroke were objectified by using the program Tracker and Zepp Tennis 2 sensor, which gave us the values of angular displacement of the body segments, the angular velocity of hip and shoulder rotation, and the ball speed, the ball spin and the percentage success rate of impact location in the sweetspot of the racket. We made a table of qualitative movement that takes into account key features of the forehand, depending on each phase of the groundstroke. Then we made a complex evaluation of the player's forehand. We concluded that it is not possible to establish a uniform ideal angular alignment of body segments. It is always necessary to respect the...
