Asymmetric stereo compression

…

Stereoscopic suppression occurs when a viewer, presented with two views of different qualities, perceives 3D at a quality close to that of the higher-quality view. The paper confirmed this effect, stating that the brain naturally discriminates between eyes, choosing a better-quality image. Information from the second image is used as auxiliary input, mainly for disparity estimation and depth perception.

3D strength versus quality of experience

Yet another paper studying the question of stereo perception quality examined the relationship between 3D effect strength (the difference between minimum and maximum disparity in a scene) and global QoE (3). The authors conducted subjective testing for various scene types in a number of videos, both captured and rendered, taking into account not only regular 2D image quality but also naturalness, overall visual comfort and depth rendering quality.
