Automation of RC Models Control with Videocamera
Záň, Drahoslav ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
Nowadays, there is a big variety of RC models, but their use and control is basicaly the same. The aim of this thesis is therefore a modification of suitable RC model in such way, that it can be controlled via PC. The model is equipped with a computer plus video camera and using wireless technology is enabled video transmission into the final destination. This modified model can be used as a simple tool to explore an unknown terrain, or for spying purposes.

System with Model Servos
Švec, Radek ; Materna, Zdeněk (referee) ; Zemčík, Pavel (advisor)
The aim of this thesis was to study the ways of controlling hobby servos, and then to design and create small machine with hobby servos. The created machine is a six-legged walking robot - hexapod with 18 servos for movement. This robot can be remotely controlled using a mobile application for Android. Main control unit of the robot is ESP32 development board. The resulting hexapod is able to walk in all directions and rotate on spot with different walking gaits. It can also change its ground clearance and walking speed. The result of this thesis is a compact walking robot with basic functions, which is suitable for extensions, eg. adding a camera or measuring sensors.

System with Model Servos
Jablonický, Jaroslav ; Nosko, Svetozár (referee) ; Zemčík, Pavel (advisor)
This work is focused on exploring how to control modeling servos by computers. It will also serve as an overview or a guide for beginners. The work includes the design of a simple robot, more precisely it is a simple robotic hand, but in particular it contains control designs from different platforms using different means. Finally, there are recommendations for each platform.

From a Dumb Boiler to a Smart One Using a Smart Socket
Mitura, Jacek ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
Nowadays, the world of smart devices is growing very fast. Nevertheless, it remains difficult to acquire smart device for water heating applications. The usual reasons complicating this fact include the lack of the possibility of connection to the central control unit, or the need to replace the entire boiler with a new smart model. In both cases, the additional disadvantage is the higher price of such a solution. Therefore, the aim of this bachelor's thesis is to create a comprehensive and affordable solution, ensuring the conversion of an existing boiler to smart using a smart socket and a central server controlling the household. The solution uses a daily consumption forecast based on an exponential moving average to save electricity.

Steganography
Podhorský, Jiří ; Kubíček, Radek (referee) ; Zemčík, Pavel (advisor)
This bachelor project focuses on steganography and presents new modifications of known metods steganography and their implementation. It also presents implementation of adaptive metod Neighbours, for comparison. Both of the metods are based on the "Least Significant Bit" exploitation. It is also demonstrated that newly proposed modification can be used in other metods of steganography. The purpose of proposed method is to encode a secret information into the digital image so that the information is not easily detectable.

Automatic User Interface Design for Remote Access
Koriťák, Jan ; Láník, Aleš (referee) ; Zemčík, Pavel (advisor)
This thesis explores the possibilities of abstraction of graphical user interface and automation of its design and development process at runtime. Emphasis is placed on possibility of remote control over computer network and accordingly on delegation of the interface creation on the human operated remote machine. The thesis analyzes contemporary approaches to and methods of interface generation. As a goal of the thesis a system for automatic user interface generation for remote applications was designed and implemented. The generation is based on specified data model.

Multispectral Image Processing
Li, You ; Juránek, Roman (referee) ; Zemčík, Pavel (advisor)
S rychlým rozvojem technologie multispektrálního zobrazování v posledních desetiletích obrázky získané zobrazovacími systémy obsahují nejen barevná pásma RGB v každodenním životě, ale také mají multispektrální barevná pásma a vysoké prostorové rozlišení v multispektrálních obrazových datech. Díky tomu obrázky obsahují bohaté informace o charakteristických cílových oblastech. Fúze obrazu je také důležitou větví v oblasti zpracování obrazu, kde je více obrázků ze stejné oblasti ve stejné výšce sloučeno do jednoho obrazu. Poté se zlepší korelace mezi spektrálními informacemi multispektrálních obrazů. Aby se informace na obrázku neztratily. Tato práce obsahuje popis návrhu a implementace multispektrálního obrazového systému, předzpracování multispektrálních obrazů, fúzi multispektrálních obrazů a analýzu hlavních komponent. Nakonec je představeno hodnocení celého systému.

Distance Measuring by Mobile Phone
Pokorný, Karel ; Zemčík, Pavel (referee) ; Szőke, Igor (advisor)
Target of this thesis is to find out the way to create a mobile phone application, that is capable of meassuring the distance, phone covers above a suitable surface, using integrated camera. Usage of one of motion detection methods is needed to reach the target. Final application uses constant optical flow estimation algorithm. It gives only one value of optical flow between two succeding video frames as a result - movement of whole scene in the picture is assumed. Application was realized for Symbian operating system with S60 3rd Edition user interface. Implementation language is C++.

Smart Home Control
Fučík, Jan ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
This thesis summarizes the subject of intelligent homes and describes commonly used standards and commercial solutions on the market. The thesis covers the design of a low-cost and easy to use smart home system which can be managed over the internet, uses a genetic algorithm for heating regulation optimization and its central computing unit is a low-cost, embedded device with low power consumption. The functionality of the system is verified on a practical application of heating regulation in a house. The efficacy of the system for energy savings is shown; it is based on measured data statistics.
