We aimed to extract object image regions contributing to translucency perception using the Classification Image method with CG images whose translucency was controlled by the strength of subsurface scattering (SSS) in order to examine image statistics related to translucency on 3D objects. The stimulus was the composition of two CG images with different SSS strengths according to a random spatial pattern. The observer simultaneously viewed the two stimuli that were created based on different composition patterns, and responded which stimulus yielded stronger translucency perception. The composition patterns of all trials were classified into two classes based on the observers' responses, and were averaged in each class. Then, we derived CIs as the differences between the averaged patterns between the two classes. The CIs showed that the observer judged the object translucency not on the whole image but on certain regions in the object images, indicating that these regions were more strongly related to translucency perception. In addition, the observer judged translucency based not on regions with clear shading luminance edges, but on regions that have little luminance variations. These results suggested that translucency perception do not strongly depend on local luminance contrast information. |
