Enhancement of Glossiness Perception by Retinal-Image Motion: Additional Effect of Head-Yoked Motion Parallax

Figure 5

Comparison of the results for each condition.

The perceived glossiness ratios of the D_image-D_observer, D_image-S_observer, and S_image-D_observer conditions to the S_image-S_observer condition for specular levels between 0.30 and 0.60 and for all specular levels. The error bars represent the standard error of the mean. The asterisks indicate the existence of a significant difference [*: p<0.05, **: p<0.01; ***: p<0.001].
