Detection of Traffic Signs and Lights
Chocholatý, Tomáš ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
The thesis focuses on traffic sign detection and traffic lights detection in view with utilization convolution neural network. The goal is create suitable detector for detection and classification traffic sign in real traffic. For training of convolution neural network were created appropriate datasets, that contains synthetic and real dataset. For synthetic dataset was create generator, that can simulated different deformation of traffic signs. Evaluation is done by own program for quantitative evaluation. The detection rate successfully detected signs is 89\% over own test dataset. The results allow to find out importance of representation real or synthetic dataset in training dataset and influence individual deformations synthetic dataset for final detection quality.

Traffic Violation Detection on Crossroads
Karpíšek, Miroslav ; Bartl, Vojtěch (referee) ; Špaňhel, Jakub (advisor)
This bachelor thesis presents procedure for the detection of red-light violation. In the theoretical part of the thesis, the current solution aproaches used in image processing are described. The practical part focuses on creation of program for automatic traffic corridors detection, vehicle tracking and the current traffic light state detection. The results obtained by experimenting with the proposed procedure and the possibilities of its further improvement are also discussed.

Video Anonymization
Mokrý, Martin ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
The goal of this thesis is to design and create an automatic system for video anonymization. This system makes use of various object detectors on an image to ensure functionality, as well as active tracking of objects detected in this manner. Adjustments are later applied to these detected objects which ensure sufficient level of anonymization. The main asset of this system is speeding up the anonymization process of videos that can be published after.

Automatic Traffic Camera Calibration for Vehicle Speed Measurement
Nociar, Marián ; Bartl, Vojtěch (referee) ; Špaňhel, Jakub (advisor)
This thesis deals with design and development of a system for Automatic Traffic Camera Calibration for Vehicle Speed Measurement. The thesis contains a theoretical introduction to the camera calibration, describes the principles of the methods used in the implementation and displays the proposed solution that was implemented in Python3 using OpenCV and NumPy libraries. The achieved results were evaluated over the BrnoCompSpeed dataset with the average speed measurement error reaching 6.71 km/h.

Fooling of Algorithms of Computer Vision
Hrabal, Matěj ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
The goal of this work was to research existing methods of computer vision and computer recognition fooling. My focus was on group of methods called pixel attacks. Another part of my thesis talks about methods of detecting and fighting against computer vision fooling. Implementation of various pixel attack methods and methods of defending against these kinds of attacks was done using the python programming language and python library Keras. Solution that I have created works as standalone application allowing user to perform various pixel attack methods on chosen image. This tool also allows collection of statistics from performed pixel attacks and is able to detect possible attacks in these images.

Information System and User Interface for Career Fair
Pavlík, Tadeáš ; Bartl, Vojtěch (referee) ; Dobeš, Petr (advisor)
This work focuses on the design and implementation of an information system and user interface for day of career opportunities at Olomouc grammar school. The aim of this thesis is to design an information system and user interface through which the presenters can apply for the event, the organizers can manage the event and interact with the visitors of the event. This thesis focuses on implementing an clear and easy - to - use user interface. The information system is implemented using Laravel framework, PHP language and Bootstrap 3 library. The thesis presents the design and implementation of database structure, use cases, information system and user interface. Testing was carried out using participants from previous years. The resultant information system is ready for deployment. The contribution of this work is simplifying the work of the organizers, providing visitors with information and getting information easily on mobile devices.

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.

Set Game for Android
Vlach, Antonín ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
The aim of this thesis was to create an adaptation of card game Set for Android devices. The application should be easy to use. Another purpose of the application is to help beginner users with understanding the game rules. The outcome is a native Android application using simple material design. The main part is a time game. There is also explanation of rules with some graphical examples. Tutorial mode provides more difficulty levels helping beginners to master the game. One game takes about 3-10 minutes (depending on players skills), therefore the game is good to make some boredom more pleasant (e.g. waiting for public transport).

Mobile App: SuperSimple Shared Shopping List
Krhovský, Patrik ; Bartl, Vojtěch (referee) ; Herout, Adam (advisor)
The aim of this thesis is to create a mobile application for sharing daily-needed stuff with your family or friends and let each other know if something runs out and buy it. For sharing this stuff between users in real time is used database Google Cloud Firestore. The application is implemented in React native and it is available for iOS and Android devices. REST API is implemented in Node.js where is saved data from the mobile application and sending push notifications to mobile devices. This work is focused on user interface design which was implemented and tested. The application is available in Apple App Store and Google Play. With this application, a user should never forget to buy what he really needs.
