Comparison of compression algorithms for high definition video
Dvořák, Martin ; Polák, Ladislav (referee) ; Slanina, Martin (advisor)
Bachelor's thesis deals with comparison and analysis of various instruments of the present-day compression algorithms used to compress high-definition video. Video sequences require a large amount of memory for their storage and take up bandwidth for their transmission, so it is necessary to compress video signals with regard to the quality of video after decompressing. The work focuses mainly on the differences between the algorithms and overall performance. Part of this work is a compressed video database, comparing the performance of different algorithms and the subjective quality of compressed video.

Picture Quality Analysis in Digital Television Systems
Bednarz, Robin ; Slanina, Martin (referee) ; Kratochvíl, Tomáš (advisor)
Diploma thesis deals with the analysis of quality in digital television systems and contains theoretical description of subjective and objective assessment of quality picture methods. The thesis contains short-term and long-term analysis of quality picture of terrestrial television DVB-T. Measurements and experimentations were carried out with the help of Rohde&Schwarz DVQ analyzer of picture quality and software MPEG-2 Quality Monitor and MPEG-2 Elementary stream analyzer.

Educational video codec
Dvořák, Martin ; Hála, Ondřej (referee) ; Slanina, Martin (advisor)
The first goal of diploma thesis is to study the basic principles of video signal compression. Introduction to techniques used to reduce irrelevancy and redundancy in the video signal. The second goal is, on the basis of information about compression tools, implement the individual compression tools in the programming environment of Matlab and assemble simple model of the video codec. Diploma thesis contains a description of the three basic blocks, namely - interframe coding, intraframe coding and coding with variable length word - according the standard MPEG-2.

Geodetic Observatory Pecny GNSS Analysis Supporting Solid Earth Tide Modelling
Nosek, Jakub ; Douša, Jan ; Václavovic, Pavel ; Běloch, Lukáš
The TILDE project deals with local solid Earth tide (LSET) modeling based on direct LSET observations using long-term GNSS time series. Geodetic Observatory Pecný of the RIGTC contributes to the TILDE project by processing GNSS data. We collected GNSS data from 98 stations, which were divided into three subnetworks. Quality control of all observational data was performed using advanced tools from the G-Nut library. High-accuracy GNSS processing using the GNSS-PPP method was performed using REPRO_2020 precise products by the CODE. The results were coordinate displacement component data. Based on these data, LSET models from individual critical areas will be created. These LSET models can be used to assess the risks of earthquakes and volcanic activity caused due to LSET.
