Evaluation of authenticity by perception-based rendering for a reflected image
  DOI :  10.2352/CIC.2012.20.1.art00018  Published OnlineJanuary 2012

This paper presents the results of subjective evaluations to investigate the authenticity of a reflected image captured at various positions on virtual object. We attribute correct reflection to visual equivalence by curvature and distortion of a surface. Here, the distortion is defined as magnification and displacement of reflected object. Using captured images and computer graphics, we attempt to confirm the sensitivity of an observer to magnification and displacement by conducting two sets of experiments. Upon conclusion of these experiments, we establish that the displacement component of the reflected image is more sensitive to the observer than that of magnification. In addition, these results suggest the importance in considering symmetrical or asymmetrical positioning of the reflection image in guaranteeing authenticity.
