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.

Image Management Toolkit
Navrátil, Rudolf ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
This work deals with the possibilities of additional entering of metadata into pictures in the form of key words. It describes the most important existing tools which make this possible. It also mentions and analyzes commonly used picture formats, standards for saving metadata in pictures and their indexing options. It provides a description of the solution to the given task and, in the conclusion, indicates the opportunities for further development.

Automatic Photo Sorting
Weiser, Michal ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
The purpose of this article is to show how intuitive can be work with pictures sorting. Drag&drop technology in combination with interactive picture moving makes this application easy to use. To sort pictures with some feature you just must drag magnetic attractor into some place in workspace and choose attracting feature with specific value. Pictures with alike value are attracted. Difference in values determines the distance between picture and attractor. Combination of many attractors can help you sort pictures in short time with just couple of clicks.

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.

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.

System for Management of Photographic Collections
Faika, Petr ; Kučiš, Michal (referee) ; Zemčík, Pavel (advisor)
Primary objective of my thesis is the choice, suggestion and implementation of a feature to manage a collection of photos. The current status regarding photography collection is described as well as two existing sotware for that purpose. Description of a photo file, choice of features, suggestion and implementation description follows. I've chosen the feature to merge photos from multiple cameras. At the end of the thesis there's a proof of results and discussion about further extension options.

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.

System for Management of Photographic Collections
Marcelyová, Andrea ; Juránková, Markéta (referee) ; Zemčík, Pavel (advisor)
This bachelor’s thesis deals with design and implementation of a selected feature to manage a collection of photos. The history and development of photography is described as well as digital image representation, ways to modify photos, metadata in digital photos and two existing applications for managing and editing photo collections. The choice of feature, design and implementation description follows. I have chosen the Exif data editing in a digital photography. The method of proving the application functionality is suggested. At the end of the thesis there is a discussion about results and further extension options.

HDR Image Composition from Multiple Images
Raszka, Aleš ; Maršík, Lukáš (referee) ; Musil, Martin (advisor)
Bachelor thesis deals with the problems of the low dynamic range of today's cameras. This problem is solved by composing multiple images with different exposures into the final HDR image. The thesis also includes performances next part of the process, which is tone mapping. The issue is packed into the resulting library in C ++ that can create HDR image.

Automatic Selection of Representative Pictures
Bank, Tomáš ; Beran, Vítězslav (referee) ; Polok, Lukáš (advisor)
This paper belongs to field of computer vision. It deals with clustering photographs by content and selection of representative one. In this paper is described a few methods and approaches to reach the goal, and proposal of algorithm comes from those approaches. The example of usage this application can be selecting a representative photo from large albums.
