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.

Object tracking in videosequence
Nešpor, Zdeněk ; Zukal, Martin (referee) ; Číka, Petr (advisor)
This thesis deals with tracking a predefined object in the movie. After a brief introduction describes the procedure suitable for the detection of an object in a video sequence, where the methods are also discussed in detail. There is dealt with issues of image preprocessing, image segmentation and object detection in the image. The main emphasis is laid on using detectors of interest points and descriptors of areas - SURF and SIFT. The second part deals with the practical implementation of a program suitable to monitor predefined object in the movie. First are analyzed libraries suitable for object tracking in a video sequence in an environment of Java, followed by a detailed description of the selected library OpenCV along with wrapper JavaCV. Further described is own application in terms of control and functionality are described key method. Outputs along with discussion and evaluation are presented at the end of work.

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.

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.
