Abstract

U radu je objašnjeno šest subjektivnih metoda za vrednovanje kvalitete 3DTV sekvenci propisanih ITU-R BT.2021-1 preporukom. Prikazan je način obrade rezultata, te su navedeni zahtjevi koji se moraju ispuniti pri subjektivnom vrednovanju kvalitete 3DTV sekvenci. Analizirani su postupci za objektivno vrednovanje 3DTV sekvenci (PSNR, SSIM, VQM. IW-SSIM i IQM2). Definirani su kriteriji za odabir sadržaja ispitnih 3DTV sekvenci, te vrste izobličenja koje se pojavljuju u 3DTV sekvencama. Odabrani su parametri kodera za kompresiju 3DTV sekvenci. Parametri su opisani za H.264 standard. Na primjeru 3DVCL@FER baze opisano je kako se oblikuje baza 3DTV sekvenci i na koji način je provedeno subjektivno i objektivno ispitivanje. Na kraju su dani rezultati ispitivanja i komentari rezultata.

Abstract (english)

This paper describes six subjective 3DTV quality evaluation methods wich are prescribed by ITU-R BT.2021-1 recommendation. Way of results processing is shown and requirements that must be fulfilled on subjective 3DTV sequence evaluation are listed. Methods for objective evaluation of 3DTV sequences (PSNR, SSIM, VQM. IW-SSIM i IQM2) are analysed. Criteria for selection of test 3DTV sequences content are defined. Parameters of encoder for 3DTV compression are chosen. Those parameters are described for H.264 standard. By example of 3DVCL@FER database, it is described how is database for 3DTV sequences formed and on which way is subjective and objective testing done. At the end of paper, results of testing and commentary of results is given.
