Algorithms for Automatic Spherical Image and Video Cropping
Ivančo, Martin ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
Cieľom tejto práce je priniesť detailný pohľad na doterajší prieskum v oblasti sférických videí. Konkrétne sa táto práca zameriava na problém tvorby videa s normálnym zorným poľom zo sférického videa pre potreby zobrazovania. Prináša tiež implementáciu niektorých dostupných metód. Doteraz boli predstavené tri metódy v štyroch článkoch, ktoré riešia tento problém. Všetky priniesli zaujímavé výsledky a táto práca sa dvomi z nich zaoberá hlbšie. Táto práca tiež prináša základnú metódu využívajúcu overené metódy automat- ického orezu obrazu. Táto metóda je využitá na porovnanie so skúmanými metódami, u ktorých zvýrazní ich vylepšenia ale aj nedostatky. Na základe porovnania metód pomocou užívateľského experimentu táto práca usudzuje, že najlepšou zo skúmaných metód pre túto úlohu je upravená varianta metódy od Pavel et al. [14], predstavená v tejto práci.
Design methods of Czech UX designers
Tsitova, Darya ; Brejcha, Jan (advisor) ; Slussareff, Michaela (referee)
(in English): The diploma thesis deals with the use of design methods among Czech UX designers in the design of web and mobile applications. The aim of this work is to find out and critically describe how Czech UX designers use design methods in practice. The thesis analyse the design process of website, web and mobile applications, its various stages and procedures. The theoretical part of the thesis introduces the basic terminology of the User Experience field and current research in the field, with emphasis on relevant terms and processes that occur in design practice. This part of the thesis is based on data obtained in the practical part, according to which popular approaches, frameworks, processes and methodologies of the UX field will be identified and described on the basis of professional literature. In the research part, qualitative research will be carried out in the form of semi-structured interviews with Czech User Experience designers, focused on the identification of methods, procedures and principles and ways of their usage. At the end of the thesis, the obtained data will be evaluated and it will be identified whether Czech designers in their practice adhere to academic approaches, or what existing and theoretically described methodologies and procedures their design process...
Virtual Waiting Room Data Base Storage
Sadloň, Matej ; Brejcha, Jan (referee) ; Kolář, Martin (advisor)
This thesis is part of project called Virtual Waiting Room. It is a cross-platform application which allows users to book a term with a provider without the need to personally wait in a waiting room. The thesis describes the design and implementation of database, library for work with this database, and a client for the administration of providers and waiting rooms. For this purpose, was used technologies such as MySQL, PHP and HTML.
Dynamic Image Presentations Using Depth Maps
Hanzlíček, Jiří ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
This master's thesis focuses on the dynamic presentation of still photography using a depth map. This text presents an algorithm that describes the process of creating a spatial model which is used to render input photography so that the movement of virtual camera creates parallax effect due to depth in image. The thesis also presents an approach how to infill the missing data in the model. It is suggested that a guided texture synthesis is used for this problem by using rendering outputs of the model themselves as guides. Additional information in model allows the virtual camera to move more freely. The final result of the camera movement can be saved to simple video sequence which can be used for presenting the input photography.
Augmented Reality on iOS - Displaying of Map Features in Terrain
Bezák, Adam ; Brejcha, Jan (referee) ; Herout, Adam (advisor)
This thesis aims to improve the user's orientation in terrain using his smartphone and augmented reality. By combining these two elements and cost-free OpenStreetMap database of geographic data, is possible to show nearby map features from the maps or show additional information about nearby objects. The resulting technology is used in implemented iOS application called Water Radar. This application displays nearby water streams (or other water objects) relative to the GPS position of the user. The application also uses Google Elevation API, in order to enable displayed water streams to follow the landscape.
Postcognitivistic HCI: Seeing interface as a sociotechnical relation
Ferenc, Jakub ; Brejcha, Jan (advisor) ; Malečková, Dita (referee)
(in English): This thesis focuses on the theories of Human-computer interaction, called by the selected authors "postcognitivistic", that react critically to the cognitivistic approach of the first- wave HCI. The working hypothesis of this work is to view the broader context of interface of technological objects as a medium of a sociotechnical relation between technological artefacts, human actors and the society. The goal of the thesis is to develop a theoretic-philosophical analysis and the comparison of how the primary sources focused on the HCI theory and sociotechnical systems, together with the chosen literature on the new media theory and philosophy of technology, contribute to the contemporary discussion about the contextual aspects of HCI, including the question of how seeing the interface as a sociotechnical relation influences the work of the designers who have to deal with the complexity of contemporary design problems.
Mobile App for Acquisition and Processing of HDR Images
Michalák, Patrik ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
The goal of this paper is to create an application that solves HDR image processing problems and focuses to interactivity with the user, offering him more opportunities in clear and minimalistic graphic user interface. Application generate HDR content by merging a series of low dynamic range images with different exposure time values. The solution provides work with HDR photography, four tone mapping methods and various tools for user.
Algorithms for Automatic Image Cropping
Ambrož, Vít ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
The main goal of this bachelor thesis is study and implementation of methods that can automatically crop images, so the result has good usability from a photographic view. In this thesis are made experiments with three methods and possible optimalizations are discussed. The properties of cropping algorithms are also described here and the evaluation of implemented algoritmhs is made according to user testing.
Web App for Capturing New Shots of Historical Photographs
Sikora, Martin ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
The aim of this diploma thesis is to design and implement a web application focused on rephotography management. Analyze existing solutions, create list of features and simple graphical user interface. It also includes a design of API structure to communicate with the mobile application. Essential application requirements include adding photos on a map and combining different photos in a photo editor with enhanced auto-alignment features.
Online System for Visual Geo-Localization in Natural Environment
Pospíšil, Miroslav ; Čadík, Martin (referee) ; Brejcha, Jan (advisor)
The goal of this master thesis is creation of an online system serving as a performing application for presentation results of visual geo-localization in nature and mountain environment. The system offers the users to choose one of the pre-defined photographs or~to~upload one's own photography while choosing a file or inserting an URL address. The~system will localizate a camera of a given image based on a visual geo-localization. The~geo-localization uses the mountain horizon as a key characteristic when searching for similar horizons. The~curve line of the horizon is extracted by a fully automatic algorithm based on supervised learning and dynamic programming. Visual geo-localization running on the server which using new inversed index with cache politic. This allows further scaling of the system. The server processing detected horizon curve and respond with set of the best candidates on results. Results are visualised to the user in form of classic map, detailed sattelite view and rendering of found panorama.
