of two projectors are same to each other. This uncomfortableness can be abated by
turning down the luminance of the dominant projector. Secondly, the difference
between the resolutions of the stereoscopic images and the stereoscopic display
device also has influence on the stereoscopic quality assessment.
Subsequently, we will investigate the relationship between the perceived qual-
ity and the distortion types and parameters. Firstly, the DMOS values on Gaussian
blurred images are shown in Fig. 2. The perceived quality values of stereoscopic
images show a decreasing trend as the distortion levels on right view images in-
creasing. But all the DMOS values are below 20 regarding the whole range of
quality score being from 0 to 100. In our opinion, the stereoscopic image quality
degradation caused by Gaussian blur is less affected by the poor quality presented
to the right eye images because subjects pay more attention to the left eye images
that have no distortion. In addition, no obvious difference between the DMOS
values on different image contents was found for the blurring distortion.
