On the appearance of translucent edges [PDF]

open access: yes2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015
Edges in images of translucent objects are very different from edges in images of opaque objects. The physical causes for these differences are hard to characterize analytically and are not well understood. This paper considers one class of translucency edges—those caused by a discontinuity in surface orientation—and describes the physical causes of ...

Top-down effects on translucency perception in relation to shape cues. [PDF]

open access: yesPLoS ONE
It is well established that object shape perception significantly influences the perception of translucency. However, how object shape cues such as motion and binocular disparity affect the perception of translucency in rich environments, like virtual ...

Translucency perception: A review

open access: yesJournal of Vision, 2021
Translucency is an optical and a perceptual phenomenon that characterizes subsurface light transport through objects and materials. Translucency as an optical property of a material relates to the radiative transfer inside and through this medium, and translucency as a perceptual phenomenon describes the visual sensation experienced by humans when ...

Comparison between different breeds of laying hens in terms of eggshell translucency and its distribution in various ends of the eggshell

open access: yesPoultry Science, 2021
: Eggshell translucency is a ubiquitous external eggshell quality problem caused by variations of eggshell ultrastructure or shell membrane. In previous studies, researchers have widely investigated this phenomenon with nutritional, environmental, and ...

Diffusion in Translucent Media [PDF]

open access: yesConference on Lasers and Electro-Optics, 2018
AbstractDiffusion is the result of repeated random scattering. It governs a wide range of phenomena from Brownian motion, to heat flow through window panes, neutron flux in fuel rods, dispersion of light in human tissue, and electronic conduction.

Influence of ZrO2 Nanoparticle Addition on the Optical Properties of Denture Base Materials Fabricated Using Additive Technologies

open access: yesNanomaterials, 2022
This study investigated the translucency of 3D-printed denture base resins modified with zirconium dioxide nanoparticles (ZrO2NPs) under thermal cycling. A total of 110 specimens were fabricated and divided into 3 groups according to the materials, i.e.,

Effects of trace minerals source in the broiler breeder diet and eggshell translucency on embryonic development of the offspring

open access: yesPoultry Science, 2023
: In 2 experiments, interactions between trace mineral (Zn, Mn, Cu, Se) source (organic or inorganic) in the broiler breeder diet and egg translucency (high or low) on egg characteristics and embryonic development were investigated.
