VR Headset Assistance for Keyboard Playing
Chomo, Michal ; Polok, Lukáš (referee) ; Šolony, Marek (advisor)
This thesis presents a design and implementation of an application for a smartphone with Android operating system, which processes image recorded with phone camera, detects keyboard in it and then displays real image from camera on phone screen with chords or scales added directly on keyboards. Phone display is split in two, so there is individual image for each eye and the phone is inserted in the Google Cardboard headset. Application is implemented in Java and using Native Development Kit also in C++, for image processing, OpenCV library is used.

Tor Network Consensus Data Stored in OLAP Database
Chomo, Michal ; Bartík, Vladimír (referee) ; Polčák, Libor (advisor)
Tor is a distributed network providing privacy and anonymity on the Internet. Information about Tor is publicly available in a form of consensus documents. Existing tools that are able to display this information do not provide both historical and detailed view of it. A tool named Consensus Parser that provides a detailed, historical view of this information and extends it with geolocation and DNS information, was created as a part of TARZAN research project at Brno University of Technology. It stores the information in regular files on disk and makes it accessible via REST API. This thesis extends Consensus Parser with MariaDB ColumnStore database with a schema designed to conform to OLAP needs. The searching capabilities of Consensus Parser were enhanced by adding 109 new endpoints to 12 existing ones and adding the ability to limit the retrieved information to certain fields only. Disk space needed for storing the information was reduced by a factor of five.
