Effect of Eye Dominance on the Perception of Stereoscopic 3D Video

TL;DR

This study investigates how eye dominance influences the perception of stereoscopic 3D video quality, revealing that aligning higher quality images with the dominant eye improves viewer experience.

Contribution

It provides the first comprehensive analysis of eye dominance effects on asymmetric 3D video perception through subjective experiments and a dedicated database.

Findings

Viewers prefer asymmetric videos when the dominant eye receives higher quality.

Eye dominance can alter perceived 3D quality scores by up to 16%.

Impact varies with type of asymmetry, often being negligible.

Abstract

Asymmetric schemes have widespread applications in the 3D video transmission pipeline. The significance of eye dominance becomes a concern when designing such schemes. In this paper, in order to investigate the effect of eye dominance on the perceptual 3D video quality, a database of representative asymmetric stereoscopic sequences is prepared and the overall 3D quality of these sequences is evaluated through subjective experiments. Experiment results showed that viewers find an asymmetric video more pleasant when the view with higher quality is projected to their dominant eye. Moreover, the eye dominance changes the mean opinion quality score by 16 % at most, a result caused by slight asymmetric video compression. For all other representative types of asymmetry, the statistical difference is much lower and in some cases even negligible.
