Efficiency of diverse video standards according to the compression factor

Magistrsko delo je osredotočeno na učinkovitost različnih video-standardov za stiskanje z izgubo podatkov. Predstavljene so različne tehnike stiskanja in razvoj standardov. V teoretičnem delu sta definirana tudi faktor stiskanja in objektivna vizualna kvaliteta. Empirična raziskava vsebuje eksperiment stiskanja različnih video sekvenc s standardi MPEG-2, MPEG-4 Visual, H.264 in H.265. V namen primerjave učinkovitosti so izračunani faktorji stiskanja pri določeni objektivni vizualni kvaliteti. Sledi razlaga rezultatov ugotovitev.Master thesis is focused on efficiency of various video standards for lossy compression. Standard development and different compression techniques are presented. Theoretical part also contains definitions of compression factor and objective visual quality. The empirical part of the thesis is conducted by an experiment on compression of multiple video sequences with MPEG-2, MPEG-4 Visual, H.264 and H.265 standards. Compression factors at specified visual qualities are calculated for the purpose of efficiency comparison and the results are given
