HDR image processing tool
Kocich, Petr ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
First part describe terms HDR, image processing and some basic terms of photography. There is describe requirements for corect capture high dynamic range scene through the use of colection of photos with same scene but with diferent exposure value. Next thing is describnig principles for connect these photos to one photo with high dynamic range. Tone mapping methods describes compression of high dynamic range to dynamic range of standard screens. Some commercial program for HDR making is describe here. Main algoritmus show possibility how display high dynamic range scene through the use of kernel of usefull areas.

HDR Tone-Mapping
Vančura, Jan ; Mlích, Jozef (referee) ; Seeman, Michal (advisor)
This thesis concerns with the introduction to the problematics of images with high dynamic range (HDR) and possibilities of HDR images compression options for display on devices with a low dynamic range (LDR). In the introduction is described historical evolution of recording of reality. It is focusing towards point of view of physics, human visual perception and digital recording. There are described the ways of generating and holding of HDR images. The thesis is corncerned to the techniques of HDR compression, it means the tone-mapping. The different techniques of tone-mapping are explained and specific aproach is targeted to the gradient domain high dynamic range compresion.

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.

Tone-Mapping HDR Images
Nejezchleb, Ivan ; Glembek, Ondřej (referee) ; Seeman, Michal (advisor)
This thesis focuses on the high dynamic range (HDR) imaging problematic. It describes process of capturing and storage of HDR images in brief. Main part of thesis deals with techniques of how to display HDR images on common visual display devices, which are not able to represent them directly. This process is called tone-mapping. It is firstly described in general and than the text focuses on several techniques of tone-mapping, mainly on tone-mapping using bilateral filtering.
