Outline of Final Research Achievements

(1) We investigate the consistency of novice and expert participants’ pearl grading skill and found that novices’ grading was significantly less concordant and consistent than experts. However novices’ consistency was relatively high.
(2) We examine the relationship between perceptual surface features and material category discrimination performance for pictures of materials. The results showed that visual feature ratings were correlated with material discrimination performance for short reaction times or short stimulus durations, while non- visual feature ratings were correlated only with performance for long reaction times or long stimulus durations.
(3) Our other experiments revealed that perceptual translucency does not rely on global luminance statistics, but rather depends on local image features within specific image regions, and that motion parallax enhances the perception of glossiness.
