Abstract
We examined the spatial frequency characteristics of the relationship between skew of the sub-band filter outputs and gloss perception. We performed two experiments to measure the effects of the adaptation to skew on perceived gloss. Both results showed that the effect of skew adaptation varied by the spatial frequency of the adaptation stimulus. These suggested that gloss perception depend on the skew of particular sub-bands. Furthermore, we performed the rating experiment to investigate the relationship between sub-band skews and perceived gloss. The result showed the similar spatial frequency dependency of perceived gloss. We concluded that human visual system uses sub-band skews to estimate the surface gloss.
