Měření kvality pro HEVC

Abstract

This diploma thesis deals with standard objective and subjective video quality assessments and with analysis of their applicability to HEVC. Also basic description of video compression standard H.265/HEVC is presented. The main focus of the thesis is a creation of the database of compressed video sequences. Important parameters and features of the reference encoder HM-12 are discussed. Selected methods of objective video quality assessments are implemented on the created database. A part of this thesis is also a suggestion of method for objective video quality assessment, application of this method and associated data collection. Final data is statistically analyzed and it’s correlation with objective tests is discussed.

Diplomová práce se zabývá popisem základních metrik pro objektivní a subjektivní hodnocení kvality videa a analýzou jejich aplikovatelnosti pro HEVC. Dále obsahuje základní popis komprimačního standardu H.265/HEVC. Hlavním zaměřením práce je vytvoření vhodné databáze komprimovaných videosekvencí. Jsou uvedeny parametry a vlastnosti referenčního enkodéru HM-12. Dále jsou na vytvořenou databázi aplikovány vybrané metody objektivního hodnocení kvality. Součástí práce je návrh metody pro subjektivní hodnocení kvality, aplikace této metody a s tím spojený sběr dat. Výsledná data jsou pak statisticky zpracována a je diskutována jejich korelace s objektivními testy.
