Color-to-Grayscale Conversions
Pospíšil, Petr ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
Grayscale pictures were never replaced by color ones and will probably never be, because they are indispensable in many areas. In this thesis was chosen three methods for color-to-gray conversion. These methods was implemented afterwards. Within this thesis was also made test set of 24 HDR pictures, which was together with existing set of 24 LDR pictures used to test and evaluate features of implemented methods. These methods were also compared from the point of accurancy and preference using questionnaire.

User Interface Using WWW for Photo Image Analysis
Balcárek, Lukáš ; Láník, Aleš (referee) ; Zemčík, Pavel (advisor)
This master's thesis deals with the user interface for machine quality assessment of the technical groups of photos. This work is written about photos, graphics editors and their evaluation. The practical part is focused on the design and creation of application with web user interface, which evaluates and compares the quality of photos. Finally is this created application with its user interface tested by users, its benefits and opportunities for further expansion are evaluated.

Web Interface for Image Processing
Wollný, Pavel ; Jošth, Radovan (referee) ; Beran, Vítězslav (advisor)
The bachelor's thesis treat of creation web interface for image processing. The basic demands for final application are defined here. Work is concerned with design client interface, server and their communication. After that implementation of these parts are described. System is based on technologies HTML, CSS, JavaScript, PHP and AJAX. Processing of photos is provided by GD library PHP and extern application, which is write with the help of library OpenCV.

HDR Image Acquisition from Sequence of Images
Staněk, Jiří ; Maršík, Lukáš (referee) ; Musil, Martin (advisor)
This bachelor thesis deals with high dynamic range image acquisition based on composition of ordinary digital photographs. Using this composition method, a program with graphical user interface is implemented. This application is able to save created images with high dynamic range or convert them to figures that are displayable on common displays using tone mapping.

Windows Phone 7 Application for Traffic Sign Recognition
Dvořák, Marek ; Orság, Filip (referee) ; Procházka, Boris (advisor)
Purpose of this thesis is to create an application that detects and recognizes traffic signs for mobile phones running Windows Phone 7 operating system. Theoretical part contains information about history and characteristics of Windows Phone 7 system, traffic signs in Czech Republic and various methods of image processing. Practical part of this thesis describes particular implementation of recognizing of traffic signs in photographs taken with mobile phone built-in camera. In last part this app is tested in real-life conditions and results of these tests are evaluated.

Digiverse Monument
Tajovský, Jakub ; Blažíček, Martin (referee) ; Resslová, Veronika (advisor)
In my diploma thesis I deal with the image on the border of digital and analog media and horizon as border of visual perception. Output is computer program, variable image, digital version of artefact. The image is the grid of pictures superimposed in horizontal strip, particular pictures we can vary for their alternatives. The image we can see from various point of view: 1. As a picture on the wall of gallery, 2. from the space behind the canvas, from where is able to contol it with cursor, 3. on the internet, as video stream.

Merging of Different Exposured Photographs, HDR
Šmida, Vladimír ; Juránek, Roman (referee) ; Seeman, Michal (advisor)
High Dynamic Range Imaging (HDRI) is an emerging field in image postprocessing with non-trivial relations to many different areas, such as image synthesis, computer vision, video and image processing, digital photography, special effects among others. This bachelor's thesis deals with the usage of HDRI in digital photography. Conventional digital cameras are not able to record the full tonal range of the scene. Therefore, if we want to capture a high dynamic range scene, by setting the exposure time we have to choose only a small range of tones which will be well depicted. The rest of the photograph will loose important detail. The method presented and implemented in the scope of this thesis enables us to create HDR picture with realistic values of tones out of several differently exposured photographs.
