Highlight-shading relationship as a cue for the perception of translucent and transparent materials.

摘要: Natural surfaces, such as those of food and drink, have translucent properties. Translucent materials involve complex optics, sub-surface scattering refraction, but humans can easily distinguish them from opaque materials. Here, we investigated image features that are diagnostic the perceived translucency transparency, focusing on fact variations in opacity a surface affect largely non-specular component (shading pattern) an little specular (highlights). In simple rating experiment with computer-generated objects, show tends to be blurred, faint, even partially contrast-reversed for objects appear more or transparent. A subsequent further demonstrated manipulation contrast blur dramatically alters apparent object. The results support notion spatial relationship between highlights shading patterns is robust cue transparency three-dimensional objects.
