SUMMARY:Perceptually Adaptive Real-Time Tone Mapping
DESCRIPTION:Technical Communications, Technical Papers\n\nTaimoor Tariq (M
 eta, Università della Svizzera italiana) and Nathan Matsuda, Eric Penner, 
 Jerry Jia, Douglas Lanman, Ajit Ninan, and Alexandre Chapiro (Meta)\n\nTon
 e mapping operators aim to remap content to a display's dynamic range. Vir
 tual reality is a popular new display modality that has significant differ
 ences from other media, making the use of traditional tone mapping techniq
 ues difficult. Moreover, real-time adaptive estimation of tone curves that
  faithfully maintain appearance remains a significant challenge. In this w
 ork, we propose a real-time perceptual contrast-matching framework, that a
 llows us to optimally remap scenes for target displays. Our framework is o
 ptimized for efficiency and runs on a mobile Quest 2 headset in under 1ms 
 per frame. A subjective study on an HDR-VR prototype demonstrates our meth
 od's effectiveness across a wide range of display luminances, producing im
 agery that is preferred to alternatives tone mapped at peak luminances an 
 order of magnitude higher. This result highlights the importance of good t
 one mapping for visual quality in VR.\n\nRegistration Category: Full Acces
