A Study on the Relationship Between Depth Map Quality and the Overall 3D Video Quality OF Experience

TL;DR

This paper investigates how the quality of depth maps influences the perceptual quality of synthesized 3D videos, highlighting the importance of depth map fidelity for optimal viewing experience.

Contribution

It provides a comprehensive analysis linking depth map quality to 3D video quality, including both subjective and objective assessments, and identifies key correlation metrics.

Findings

Depth map quality significantly affects 3D video perception.

Visual Information Fidelity index correlates with subjective 3D quality.

Strong Pearson and Spearman correlations demonstrate the importance of depth fidelity.

Abstract

The emergence of multiview displays has made the need for synthesizing virtual views more pronounced, since it is not practical to capture all of the possible views when filming multiview content. View synthesis is performed using the available views and depth maps. There is a correlation between the quality of the synthesized views and the quality of depth maps. In this paper we study the effect of depth map quality on perceptual quality of synthesized view through subjective and objective analysis. Our evaluation results show that: 1) 3D video quality depends highly on the depth map quality and 2) the Visual Information Fidelity index computed between the reference and distorted depth maps has Pearson correlation ratio of 0.75 and Spearman rank order correlation coefficient of 0.67 with the subjective 3D video quality.
