SUMMARY:Perceptually Adaptive Real-Time Tone Mapping
DESCRIPTION:Technical Papers\n\nTaimoor Tariq (Meta, Università della Sviz
 zera italiana) and Nathan Matsuda, Eric Penner, Jerry Jia, Douglas Lanman,
  Ajit Ninan, and Alexandre Chapiro (Meta)\n\nTone mapping operators aim to
  remap content to a display's dynamic range. Virtual reality is a popular 
 new display modality that has significant differences from other media, ma
 king the use of traditional tone mapping techniques difficult. Moreover, r
 eal-time adaptive estimation of tone curves that faithfully maintain appea
 rance remains a significant challenge. In this work, we propose a real-tim
 e perceptual contrast-matching framework, that allows us to optimally rema
 p scenes for target displays. Our framework is optimized for efficiency an
 d runs on a mobile Quest 2 headset in under 1ms per frame. A subjective st
 udy on an HDR-VR prototype demonstrates our method's effectiveness across 
 a wide range of display luminances, producing imagery that is preferred to
  alternatives tone mapped at peak luminances an order of magnitude higher.
  This result highlights the importance of good tone mapping for visual qua
 lity in VR.\n\nRegistration Category: Full Access, Enhanced Access, Trade
