![]() These results provide new insight into how the visual system might infer translucency from the structure of specular and non-specular shading generated by glossy semi-opaque materials.ģD shape Image feature Material perception Translucency Visual perception.Ĭopyright © 2022 Elsevier Ltd. This model was found to outperform other models based on explicit subjective measures of perceived surface shape, suggesting it implicitly taps much of the relevant geometric information necessary for predicting observer judgments of translucency for glossy materials. We proposed a new computational model based on measurable image features informative of shading relative to specular highlights that accounted for 59% of the variability in judgments of perceived translucency from the result of 10-fold cross validation. Translucency (also called translucence or translucidity) allows light to pass through, but does not necessarily (again, on the macroscopic scale) follow Snells law the photons can be scattered at either of the two interfaces, or internally, where there is a change in index of refraction. The object or material which allows light to pass through completely is called a Transparent object or transparent material. Results revealed that perceived translucency could be explained by incongruence in 3D shape used to generate specular and non-specular image components. Here, we performed experiments to test whether interactions between specular and non-specular image properties generated by different 3D shape information influences perceived translucency. A translucent material allows light to pass through, but prevents the light from forming images. ![]() It is possible for an object to be transparent to one type of wave but opaque to another. We considered the possibility that perceived translucency might also depend on 3D shape inferred from surface gloss (i.e., shape from specular highlights). Objects are classified as opaque, transparent, or translucent based on how they interact with waves. Labeled examples with light passes through glass or objects. Transparent, translucent or opaque physical properties explanation vector illustration. See transparent translucent opaque stock video clips. Understanding how we visually perceive translucency from these images is challenging, but previous studies have demonstrated that perceived shape and shading is important for perceiving translucency. 1,376 transparent translucent opaque stock photos, vectors, and illustrations are available royalty-free. Translucent objects (like fruit and wax) reflect and transmit incident light to generate complex retinal image structure. ![]()
