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.

Design of digital camera
Miklica, Martin ; Chorý, Tomáš (referee) ; Zvonek, Miroslav (advisor)
This work deals with the history, present and future of photography. The main objective however is to design a stylish compact digital camera with regard to the requirements of modern life, such as the expansion of internet social networks and the associated use of the camera as a visual scrapbook. Emphasis was placed on a new shape solution, simple operation and good ergonomics of holding.

Time-Gathering Video
Kárníková, Pavlína ; Sumec, Stanislav (referee) ; Herout, Adam (advisor)
This bachelor essay describes problems of creating time-gathering video, image processing and the theory of photography. Purpose is created program, which can modify photos and after that create video. Program is implemented in the C and C++ language and uses the OpenCV library. Application can run in the operation system Windows.

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.

Realization of digital exposure meter
Vacula, Richard ; Michal, Vratislav (referee) ; Frýza, Tomáš (advisor)
Bachelor’s thesis deals with the history of light measurement, ways of measuring exposure and constructions of exposure meters. In the last chapters it is treated of the realization of digital exposure meter. This project also examines the characteristics of digital light sensor ISL29003 and its use for purposes of measuring exposure.

Merging and Correction of Photos
Trčka, Jan ; Bařina, David (referee) ; Zemčík, Pavel (advisor)
The aim of this work is to design and implement an application using an OpenCV library. This paper describes issues of correct photo merging, attempts to eliminate defects which were created in process of taking these photos and which may occur in the actual merging process.

Detection of eyes in facial images by means of Hough transform
Janovič, Tomáš ; Čmiel, Vratislav (referee) ; Walek, Petr (advisor)
The thesis discusses the detection of eyes in facial images by means of Hough transform. It is dedicated in the necessary preprocessing of the image, especially in edge detection. Further it discusses the Hough transform itself and describes the method for detection of simple shapes such as lines and circles. Subsequently, the thesis illustrates the implementation of Hough transform for detecting circles along with an algorithm evaluating Hough space. The last part contains the results and an assessment of detection algorithm along with a discussion of utilization the Hough transform for detection of eyes in facial images.

Mapping Time of Creation of Multimedia File to Position where It Was Taken
Jurča, Josef ; Rozman, Jaroslav (referee) ; Horáček, Jan (advisor)
The aim of the bachelor thesis is to create a web application which enables uploading and localization of photographs and video sequences and displaying them on the map. The position of photos is to be extracted from its EXIF metadata. If necessary information is not contained in the EXIF metadata, coordinates are to be assigned by use of external log from GPS receiver and the time of creation of the photo. Location of photo is to be displayed with use of the points on the map. The GPS coordinates are to be assigned to the video with help of external GPS log and time of last modification of the file. The application is to enable displaying actual position and route during video playback. The thesis also describes formats of multimedia data and its metadata, the GPS system and possible ways of using the system. Afterwards existing solutions of localization of multimedia data on the map are compared and consequently it is focused on design and implementation of the new application. The thesis also deals with the process of testing of the final application and summarizes its software requirements and limits. In conclusion achieved solution is evaluated and proposals of future progress of the application are made. The outcome of the thesis is functional web application which enables user to upload multimedia data and subsequently assign their position and display them on the map.
