Material and shape perception based on two types of intensity gradient information
Fig 20
(a) Ratings for the glossiness judgment and (b) for the non-uniformity judgment are plotted as a function of the skewness of the intensity histogram. Stimulus conditions are shown as in the legend. Error bars indicate ± 1 SEM across observers. The ratings for the object with veridical highlights in Experiment 1 (Fig 10(A)) are plotted again in the glossiness judgment (red).
