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.

Traffic image sequence classification
Vomela, Miroslav ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
The article introduces a general survey of concepts used in traffic monitoring applications. It describes different approaches for solving particular steps of vehicle detection process. Analysis of these methods was performed. Furthermore this work focuses on the design and realization of complex robust algorithm for real-time vehicle detection. It is based on analysis of video-sequence acquired from static camera situated on highway. Processing consists of many steps. It starts with background subtraction and ends with traffic monitoring results, i.e. average speed, number of cars, level of service etc.

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...

Analysis of techniques in wild water kayaking during competitions in wild water slalom
Buchtel, Michal ; Bílý, Milan (advisor) ; Süss, Vladimír (referee)
Title: Analysis of techniques in wild water kayaking during competitions in wild water slalom Objectives: 1. To analyze race runs of the best world kayakers in top competitions in wild water slalom in frequency of use of individual types of strokes and technics of passing through upstream and downstream gates 2. Determine the percentage of using forwards and driving strokes in competition runs of best world kayakers Methods: Observationally descriptive study based on organized, non-behavioral observation of a targeted sample of the population of athletes, specifically a group of top kayakers. Sequence video analysis in the Darthfish computer program, based on the recording of predefined technical elements that appear in the competition runs of the best world kayakers. The observation was done by one professional expert by intra-observating method. The data was processed in the Microsoft Excel computer program using basic statistics. The individual outputs were described in details. Results: Top world kayakers are mostly using sweep technique when passing through the upstream gates in competitions There is a high share of forwards strokes against driving strokes in competition runs of top world kayakers Key words: wild water slalom, technique, tactics, competition, passing gates, video analysis

Technique on C1 in White water slalom
Foukal, Pavel ; Bílý, Milan (advisor) ; Busta, Jan (referee)
Title: Technique on C1 in White water slalom Objectives: The aim of the bachelor thesis is to describe the current concept of the technique on C1 category and create as an attachment video samples of the individual techniques, which will also be available electronically. Methods: At work we used the analysis method. Applied it in the analysis of the individual ways of going thru the slalom gates. We focused on key aspects of the all different techniques and attempted to describe them. Results: This work represents the contemporary concept of the technique and tactics of paddling on C1 and together with the annex is an output which can serve as a methodical material to canoe slalom competitors and coaches. Keywords: canoe, canoe slalom, upstream gates, downstream gates, technique, tactics, video analysis
