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.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
