Web for HDR Image and Video Processing
Beran, Martin ; Beran, Vítězslav (referee) ; Čadík, Martin (advisor)
The main goal of this bachelor thesis is the creation of web system, by which it is possible to convert photos and videos into HDR format and then adjust and display them. During processing and adjusting it is possible to see the actual view in the miniature of subsequent photo. After completing the adjusments it is possible to display and download the final file in full resolution. For interaction with user is prepared interface for uploading photos and a set of operators and filters for their adjustment.

HDR Composition for Dynamic Scene
Martinů, Lukáš ; Musil, Martin (referee) ; Maršík, Lukáš (advisor)
Master's thesis is focused on capturing of low dynamic range images using common devices such as camera and its multiple exposure. The main part of thesis is dedicated to composing these images to HDR image, inclusive sequence of images of static scenes, but also dynamic ones. Next part describes tone mapping used for display HDR image on LDR monitors. Moreover, there is given design and implementation of application solving problems mentioned earlier. In the end, the implemented application is evaluated and the possible continuation of this work is stated.

Temporal Tone-Mapping Methods for HDR Video
Staněk, Jiří ; Musil, Petr (referee) ; Nosko, Svetozár (advisor)
The diploma thesis provides the theoretical background needed to understand the complex topic of high dynamic range, and deals with the implementation of an innovative method for temporal video tone-mapping. At first, high dynamic range image acquisition, storage and processing are described. Afterwards, a general introduction to tone-mapping, description of undesirable image artifacts and an overview of existing state-of-the-art algorithms are presented. The part which follows focuses on the implementation of the chosen method and proposes several additional enhancements of the initially selected algorithm. Based on the information provided, an application with an intuitive graphical interface, which can be used for temporal HDR video tone-mapping, has been created. Finally, the the achieved results are demonstrated and visually compared with existing methods for temporal video tone-mapping.

Advanced HDR image viewer
Wirth, Michal ; Křivánek, Jaroslav (advisor) ; Wilkie, Alexander (referee)
04.01.17 abstract.txt 1 file:///home/misa/Desktop/dp/abstract.txt The primary purpose of this thesis is to determine criteria for a high- dynamic range (HDR) image viewer accented by computer graphics artists and other users who work with HDR images produced by physically-based renderers on a daily basis. Also an overview of already existing solutions is present. Based on both of them, a new HDR viewer is designed and implemented giving an emphasis on its memory and performance efficiency. For these purposes two alternative image data layouts, Array-of-Structures (AoS) and Structure-of-Arrays (SoA), are discussed and their impact is measured on the speed of an algorithm for changing image saturation which has been selected as a representative part of whole tone mapping process of the viewer. It has turned out that the latter type of layout allows the algorithm to run about 3 times faster or more under the conditions of a defined testing environment. The thesis has two main contributions. First it gives the above users a tool which could help them when working with HDR images. Second it indicates that there may be a potential of significant speed-up of implementations of tone mapping algorithms.
