Signalling gateway for videoconferencing
Seifert, David ; Číka, Petr (referee) ; Zukal, Martin (advisor)
Generally, the term gateway (gateway) in computer networks holds a node that connects two networks with different protocols. This thesis deals with the translation between two protocols, SIP protocol and WebSocket. This translation is the work first described theoretically and then work deals with the way this translation solutions using tools available on the Internet.

Object Description in Images
Dvořák, Pavel ; Šmirg, Ondřej (referee) ; Zukal, Martin (advisor)
This thesis consider description of segments identified in image. At first there are described main methods of segmentation because it is a process contiguous before describing of objects. Next chapter is devoted to methods which focus on description identified regions. There are studied algorithms used for characterizing of different features. There are parts devoted to color, location, size, orientation, shape and topology. The end of this chapter is devoted to moments. Next chapters are focused on designing fit algorithms for segments description and XML files creating according to MPEG-7 standards and their implementation into RapidMiner. In the last chapter there are described results of the implementation.

SIP Protocol Implementation
Dušek, Martin ; Zukal, Martin (referee) ; Číka, Petr (advisor)
This Master’s thesis deals in detail with the SIP protocol – a method of communication between two entities, various types of transmitted messages and their content. Few SIP libraries are introduced and two of them are used for development of an application for audio/video conference-calls. Compilation of OPAL and PTlib libraries for Windows 7 Professional (64bit) is described, and problems resulting from lack of information provided by authors. New improved “how to build” is presented. At the end, paper focuses on several ways of development of mentioned application.

Porovnání technologií dojicích robotů značky Fullwood
ZUKAL, Martin
The topic of this thesis is: Problematics of Fullwood milking robots. Milk, mammary gland anatomy, milk production and milking are described in the literature review. The overview also deals with the methods of milking, machine milking and automated milking. In the practical part were selected two farms with milking robot Fullwood M2erlin, and were monitored parameters such as the number of milked cows in 24 hours, the number of tumbling and unset milking kit, milking time and daily yield from 1 January 2018 to 31 December 2018. These parameters were subsequently evaluated and analyzed. The results were processed into tables.

Stroje pro sklizeň píce: příprava výukových materiálů
ZUKAL, Martin
This bacalar thesis provides an overview of forage harvesting machines. The thesis is divided into chapters according to individual types of machines and provides a view of their agrotechnical requirements, partition, description of basic carried out operations and description of their basic work. The bacalar thesis should serve as supplementary teaching text for students of the Department of Agricultural, transport and handling Technology of the Faculty of agriculture of South Bohemian University. Information and parameters are found in the technical literature on agricultural machinery, promotional materials and websites of manufacturers and vendors of this technique.

SIP client with advanced features
Šacl, Vojtěch ; Číka, Petr (referee) ; Zukal, Martin (advisor)
The main objective of this thesis is the design and implementation of client software, which will be able to conduct text and video communication over an IP based network. The client application is supposed to run from a web page without the need of any additional software. The first part describes possible technologies suitable for the development of such an application. After that follows a brief description of the selected technology with emphasis on SIP protocol. The thesis also includes a brief description of characteristics of libraries that were considered for implementation into the application. The proposed solution consists of the description of the graphic environment and behavior of the application. The developed application is tested in different situations in the last part of the thesis.

Video conference in HTML 5
Wiesner, David ; Zukal, Martin (referee) ; Číka, Petr (advisor)
This bachelor thesis follow proposal and realization of client-type web application, which uses SIP protocol for multimedia communication signalization. The communication is relayed via TCP protocol, more precisely via WebSocket. There are described basic properties of SIP and WebSocket protocols together with information about webRTC in first part of this thesis. The main part of thesis describes proposal and implementation of web application for AV and text communication. The briefing about progress reached during development is mentioned here as well as used libraries. Application was tested after finishing.

Detection of groups of people in images
Mikulčík, Ondřej ; Zukal, Martin (referee) ; Číka, Petr (advisor)
This work describes two methods for detecting objects in images. The first method is the Viola-Jones, the second is the method of histograms oriented gradients. Start of work deals with the theoretical description of the methods. In the other parts of this work is presented creation of the training databases, implementation methods in the RapidMiner and their testing. In conclusion, the results and the use of methods for detection of groups of people in the database of images are evaluated.

Open-source systems for image processing
Slinták, Vlastimil ; Zukal, Martin (referee) ; Mikulka, Jan (advisor)
The aim of this document is to describe open-source libraries for image processing — ITK, VTK and OpenCV. Their architectures are described and it is shown how to compile and use them in real applications. It also provides basic description of algorithms for image processing. In the second part of this document, we try to use ITK library with data-mining environment RapidMiner.

On-line Communication Client
Húserka, Jozef ; Zukal, Martin (referee) ; Číka, Petr (advisor)
Main focus of this thesis is protocol XMPP (Extensible Messaging and Presence Protocol) and its implementation into on-line client built in JAVA programming language. Purpose of XMPP protocol is to deliver messages in real-time between two or more users. It’s standardized protocol with open specification based on XML (Extensible Markup Language). This thesis describes various aspects and specifications of XMPP protocol, the way the messages are exchanged between users, various types of XML information contained in stream which is exchanged between entities in network and generally describes functioning of XMPP protocol. The output of this thesis is an on-line client for instant messaging developed using Smack API package for JAVA – various aspects of this package are described in this document alongside explanation of implementation of the client.
