DOI: 10.3389/fnbot.2022.1041702
Abstract: Obtaining accurate depth information is key to robot grasping tasks. However, for transparent objects, RGB-D cameras have difficulty perceiving them owing to the objects' refraction and reflection properties. This property makes it difficult for humanoid… read more here.

DOI: 10.3389/fpsyg.2022.766056
Abstract: Specular reflections and refractive distortions are complex image properties of solid transparent objects, but despite this complexity, we readily perceive the 3D shapes of these objects (e.g., glass and clear plastic). We have found in… read more here.
