SUMMARY:The effect of display capabilities on the gloss consistency betwee
 n real and virtual objects
DESCRIPTION:Technical Papers\n\nBin Chen (Max-Planck-Institut für Informat
 ik); Akshay Jindal (Intel Corporation, University of Cambridge); Michal Pi
 ovarči (Institute of Science and Technology Austria); Chao Wang and Hans-P
 eter Seidel (Max-Planck-Institut für Informatik); Piotr Didyk (Università 
 della Svizzera italiana); Karol Myszkowski (Max-Planck-Institut für Inform
 atik); Ana Serrano (Universidad de Zaragoza); and Rafał K. Mantiuk (Univer
 sity of Cambridge)\n\nA faithful reproduction of gloss is inherently diffi
 cult because of the limited dynamic range, peak luminance, and 3D capabili
 ties of display devices. This work investigates how the display capabiliti
 es affect gloss appearance with respect to a real-world reference object. 
 To this end, we employ an accurate imaging pipeline to achieve perceptual 
 gloss match between a virtual and real object presented side-by-side on an
  augmented-reality high-dynamic-range (HDR) stereoscopic display, which ha
 s not been previously attained to this extent. Based on this precise gloss
  reproduction, we conduct a series of gloss matching experiments to study 
 how gloss perception degrades based on individual factors: object albedo, 
 display luminance, dynamic range, stereopsis, and tone-mapping operator. W
 e support the study with a detailed analysis of individual factors, follow
 ing by an in-depth discussion on the observed perceptual effects. Our expe
 riments demonstrate that stereoscopic presentation has a limited effect on
  gloss matching task on our HDR display. However, both reduced peak lumina
 nce and dynamic range of the display reduce the perceived gloss. This mean
 s that the visual system cannot compensate for the changes in gloss appear
 ance across luminance (lack of gloss constancy), and the tone mapping oper
 ator should be carefully selected when reproducing gloss on low dynamic ra
 nge (LDR) display.\n\nRegistration Category: Full Access\n\nSession Chair:
