Ball Tracking in Sports Video
Motlík, Matúš ; Špaňhel, Jakub (referee) ; Bartl, Vojtěch (advisor)
This master's thesis deals with automatic detection and tracking of a soccer ball in sports videos. Based on the introduced techniques focusing on tracking of small objects in high-resolution videos, effective convolutional neural networks are designed and used by a modified version of tracking algorithm SORT for automatic object detection. A set of experiments with the processing of images in different resolutions and with various frequencies of detection extraction is carried out in order to examine the trade-off between processing speed and tracking accuracy. The obtained results of experiments are presented and used to form proposals for future work, which could lead to improvements in tracking accuracy while maintaining reasonable processing speed.

Vehicle On-Board Camera Analysis
Kadeřábek, Jan ; Bartl, Vojtěch (referee) ; Špaňhel, Jakub (advisor)
This thesis focuses on analysis of video from vehicle on-board camera. During the process of analysis, probihibitory traffic signs are detected and their specific type is classified. For recognized speed limit signs, their numeric value is extracted. From the processed information, it will try to create a file containing the unique occurrences of traffic signs including their GPS coordinates. For the purpose of detection and recognition of traffic signs, several data sets were created. A~cascade classifier with LBP features is used as a detector. Classification of the type and value of traffic signs is done using the k-Nearest Neigbour method.

Mapping the Motion of People by a Stationary Camera
Bartl, Vojtěch ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
The aim of this diploma thesis is to obtain information on the motion of people in a scene from the record of the stationary camera. The procedure to detect exceptional events in the scene was designed. Exceptional events can be fast-moving persons, or persons moving in di erent places than everyone else in the scene. To trace the motion of persons, two algorithms were applied and tested - Optical flow and CAMSHIFT. The analysis of the resulting motions is performed by monitoring the progress of motion, and its comparison with the other motions in the scene. The analysis result is represented by detected exceptional motions that can be found in the video. The areas where the motion occurs in the scene, and where the motion is the most common are also described together with the motion direction analysis. The exceptional motion parts extracted from the video represent the main result of the work.

Web App for Simple Editing of Short Text with Limited Vocabulary
Poláčeková, Simona ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
The aim of this thesis is a draft, an implementation and subsequent testing of a simple and user-friendly web application, which makes use of a limited dictionary to check the language. The limited dictionary is a dictionary of the most commonly used Czech words. The application can be used for simple writing of texts. The user can test if he can write a more complex thought, sentence or text using only the most commonly used Czech words. The introduction of this thesis describes the technologies used to make this application, their functionality and the way in which they are used. Then there is described implementation of the application. As a conclusion, there is a summary of the testing of the application by users and the overall results of this bachelor thesis.

Mobile Application for Finding Meeting Participant Photos
Červený, Martin ; Bartl, Vojtěch (referee) ; Beran, Vítězslav (advisor)
The goal of this work is to design and implement an application to find meeting participants, their photos and to manage these meetings with the ability to write notes. The application should make preparations for these meetings more efficient. For the successful development, the target group survey, the requirements analysis and subsequently the design and implementation were performed. The result is a functional mobile application that is tested with aspect to usability of the user interface.

Recognition of Driving Lane Borders in Video from On Board Camera
Letovanec, Lukáš ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
This thesis is dedicated to the issue of driving lane borders recognition in frames of an onboard camera. In this thesis, an architecture of a deep convolutional neural network is introduced, by means of which the said problem is dealt with. The net was trained on a large dataset using gradient descent algorithm. The trained model has demonstrated the ability to recognize borders of a driving lane well in different situations and conditions. The result of the thesis confirms that deep convolutional neural networks are a suitable tool for driving lane borders recognition.

Web Tool for Testing Based on Q-Sorting
Persich, Alexandr ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
Q-sorting is one of many methods used to determine people's subjectivity. The main goal of this thesis is to present ways used to design and create web application for Q-sort method. I have been focusing mainly on designing user interface which greatly affects the number of successfully finished surveys. To accomplish this, I have used common web technologies. The result is a web tool which allows to create and manage new surveys. For respondents it provides simple and intuitive user interface which makes the process of Q-sorting easier.
