Digital equalizer with dynamic range compression
Šafer, Radim ; Kováč,, Michal (referee) ; Brančík, Lubomír (advisor)
The aim of the thesis is to create a digital equalizer with dynamic range compression. The master's thesis is focused on the comparison of functions and parameters of individual digital processors which are given entirely for sound signals processing. It contains the detailed analysis of singular blocks used for signal processing in the circuit AD1953 and possibilities of control over programmable parametres of those blocks by a user. This thesis also contains a comparasion of the chosen A/D converters together with a description of the UDA1361TS circuit. A designed functional diagram of the final device is introduced as well. Thereafter possibilities of controling the individual blocks in the signal processor are mentioned. The final design of the digital equalizer is also introduced along with a description of software essential to a successful control over the processing of the signal in the AD1953 circuit. This thesis also describes a construction of the digital equalizer and involves results of the chosen measurements.

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.

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.
