Material and shape perception based on two types of intensity gradient information
Fig 10
(a) Rating results for the glossiness judgment plotted as a function of the skewness of the intensity histogram. Error bars indicate ± 1 SEM across observers. (b) The perceived tilt (left) or slant (right) for the histogram-modulated object plotted as a function of those for each original object. Different symbols indicate different skew parameters as shown in the legend.
