Abstract

U ovom radu prvo su ukratko objašnjene značajke ljudskog vizualnog sustava koje omogućavaju percepciju dubine (stereoskopski vid). Zatim je dan pregled tehnika generiranja stereoskopskih 3D slika te formata prikaza 3D sadržaja. Nakon tog su objašnjena moguća izobličenja specifična za prikaz 3D sadržaja. Ukratko je objašnjen postupak subjektivnog ispitivanja kvalitete i objašnjene su neke objektivne metode (PSNR, SSIM, IQM2, 3D-SSIM) za ispitivanje kvalitete 3D slike i videa. Provedeno je objektivno ispitivanje kvalitete slike na odabranoj bazi 3D videosekvenci. Na kraju je donešen zaključak o tome koja objektivna metoda pokazuje najbolje rezultate u usporedbi sa subjektivnim ispitivanjima kvalitete.

Abstract (english)

In this thesis, first the features of the human visual system that enable perceiving depth have been briefly described (stereoscopic vision). Then, an overview of the existing techniques for generating 3D stereoscopic images has been given and formats used for displaying 3D content have been explained. Specific distortions for 3D content have been listed and described. The process of subjective evaluation is briefly introduced, followed by the explanations of some of the objective assessment methods used for measuring quality of 3D content (PSNR, SSIM, 3D-SSIM, IQM2). The objective quality measuring has been conducted on a 3D videosequences database. In result, a conclusion on which objective assessment method is the best is given, based on correlations with MOS scores of the subjective evaluation.
