Design of Grammar and User Interface for Visualization and Filtration of Spatio-Temporal Data of Road-Users
Hauerland, Richard ; Zbořil, František (referee) ; Rozman, Jaroslav (advisor)
Objective of this thesis is about design of grammar and user interface for filtering and visualization of spatiotemporal data. The initial task is to get acquainted with evaluation of traffic data based on trajectory analysis. The next part is the design and description of a formalism which allows spatial filtering and filtering based on static and dynamic attributes. Based on the created formalism, data analysis application with a user interface is designed. Design process was preceded by a comparison of existing solutions. Application is implemented in Qt Framework using C++ and QML languages.
Active Learning for Processing of Archive Sources
Hříbek, David ; Zbořil, František (referee) ; Rozman, Jaroslav (advisor)
This work deals with the creation of a system that allows uploading and annotating scans of historical documents and subsequent active learning of models for character recognition (OCR) on available annotations (marked lines and their transcripts). The work describes the process, classifies the techniques and presents an existing system for character recognition. Above all, emphasis is placed on machine learning methods. Furthermore, the methods of active learning are explained and a method of active learning of available OCR models from annotated scans is proposed. The rest of the work deals with a system design, implementation, available datasets, evaluation of self-created OCR model and testing of the entire system.
Comparison of JavaScript-Based Web Application Development Tools
Gajdošík, Jakub ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
The aim of this work is to explore the modern web application development process. Comparison of procedures and tools used in web application development. The work will be mainly focused on a new trend, web application development using JavaScript using various frameworks. The work will compare two frameworks for application development.
Path Planning for Autonomous Vacuum Cleaners
Hranický, Jan ; Janoušek, Vladimír (referee) ; Rozman, Jaroslav (advisor)
Complete coverage path planning is a task of finding such path that passes over all points in given area at least once. This thesis applies complete coverage path planning to autonomous vacuum cleaner robots. Thesis summarises current deal of autonomous vacuum cleaner robots. But mainly it focuses on describing complete coverage algorithms. Selected algorithms are implemented using Java vizlib library.
Additional Metadata Management for Music Files: Finding Original Vinyl Records Metadata
Svěrák, Tomáš ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
The main goal of this work is to design and create an application that searches online music databases for information about the original vinyl records. It is a cross-platform desktop application that searches for data in Discogs, MusicBrainz, 45cat and 45worlds databases and stores them in a local database. It then allows the user to manage the retrieved information in a user-friendly interface and on their basis to decide on originality of the found recordings.
Distributed iOS System for Internet Marketing
Klembara, Radovan ; Rozman, Jaroslav (referee) ; Hrubý, Martin (advisor)
The goal of this thesis is to design and implement distributed system, which covers work with internet surveys. The result of this thesis is a system consisting of mobile application for devices with iOS operating system and server application. Mobile application is created to mediate surveys operations. Server application maintains data in database. Thesis also focuses on creating the motivational system, to improve response rate.        In this thesis I created mobile application for devices with iOS operating system, which version is not older than iOS 14. I have created server application maintainig PostgreSQL database. In the thesis I am solving user motivation for filling surveys with a reward system. For each filled survey every user is rewarded by some amount of inner application currency. This currency can be exchanged for discount coupons.      Solution of this thesis brings mobile application to users, where they can efectively fill up surveys, get rewards and buy coupons. Users also can create surveys and are able to receive survey results. It is possible to add new coupons to motivate other users.
Testing of Coverage Path Planning
Krajňák, Damián ; Janoušek, Vladimír (referee) ; Rozman, Jaroslav (advisor)
The aim of this thesis is to design and implement a program with graphical user interface, designed for algorithm testing and complete coverage of a given area. Problem was solved by decomposition of a 2D space into cells, which were sequentially covered. The areas of individual cells are covered in a way, that is selected based on the selected algorithm. Created solution provides a draft of an optimal pathway for robots intended for complete coverage of space, which are, for example, autonomous vacuum cleaners, cleaning robots, robotic lawn mowers etc.
Design and Implementation of IoT for Monitoring and Control of Smart Homes
Smejkal, Jakub ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
This thesis deals with a generic design and implementation of an IoT system, specifically for a smart home. The thesis aims to compare existing systems and hardware solutions. In this thesis there are a few examples of hardware firmwares and a prototype of a software for controlling and monitoring. The selected problem is resolved by designing a general system for a smart home. As a sample implementation, the system will be created by using hardware devices from Czech company HARDWARIO and sensors from various vendors. It will contain some environmental sensors, motion detectors, etc. The implemented prototype of an application allows easy monitoring of the whole home in one place thanks to an uncluttered UI, which is fully customizable for the user's needs.
Automatic Adjustment of Photographed Documents
Kuchta, Lukáš ; Šátek, Václav (referee) ; Rozman, Jaroslav (advisor)
This work deals with the automatic editing of photographed documents, specifically the creation of a library that will take care of cropping, alignment, transformation and brightness editing of photographed documents. The goal is to use this library to create a program into which a photo of the document is uploaded and which returns a modified version of the document. The functions of the OpenCV library for the Python programming language are used for the implementation of the library, specifically the functions for finding the edges of the document pages, their cropping, alignment and brightness adjustment. The PyQtlibrary is used to create the graphical user interface of the resulting program. The goal was fulfilled, a program with a pleasant user interface for automatic editing of photographed documents was created. The benefit of this work is the possibility of using the created program to detect documents in the image and edit them.
Differential GPS
Lebó, Denis ; Hrubý, Martin (referee) ; Rozman, Jaroslav (advisor)
My thesis studies the navigational technology for determining the current location of an object -- differential global navigational system (DGPS) with real-time kinematic (RTK) enhancement. The use of this technology is calculating the position of an object in real-time using two GNSS recievers. These recievers are used to acquire positional information from GNSS satellites (GNSS technology), which is then made more precise by the exchange of information between the recievers(DGPS/RTK technology). The thesis also provides a way to visualize the acquired location and provides a channel of communication for the GNSS recievers using the internet. The channel of communication will be provided by the program SNIP made by SubCarrier Systems. The correctional data from the GNSS recievers will be transmitted using the NTRIP (Network Transport of RTCM via Internet Protocol) protocol. For the creation of the website the web application framework Flask, written in Python, was chosen.  For the visualization of the acquired location the platform with use of the application programming interface developed by for this platform -- Mapy API was chosen.
