DESCRIPTION:Abstract:\nIn stereoscopic displays\, such as those used in VR
 /AR headsets\, our eyes are presented with two different views. The dispar
 ity between the views is typically used to convey depth cues\, but it coul
 d be also used to enhance image appearance. We devise a novel technique th
 at takes advantage of binocular fusion to boost perceived local contrast a
 nd visual quality of images. Since the technique is based on fixed tone cu
 rves\, it has negligible computational cost and it is well suited for real
 -time applications\, such as VR rendering. To control the trade-off betwee
 n contrast gain and binocular rivalry\, we conduct a series of experiments
  to explain the factors that dominate rivalry perception in a dichoptic pr
 esentation where two images of different contrasts are displayed. With thi
 s new finding\, we can effectively enhance contrast and control rivalry in
  mono- and stereoscopic images\, and in VR rendering\, as confirmed in val
 idation experiments.
