The perception of cast shadows
Trends in Cognitive Sciences, 1998 When an object casts its shadow on a background surface, the shadow can be informative about the shape of the object, the shape of the background surface and the spatial arrangement of the object relative to the background. Among all these roles, we found that cast shadows were perceptually most relevant for the recovery of spatial arrangement ...

Casting a Shadow on Lewis’s Theory of Causation
Organon F, 2019 First I present a puzzle involving two opaque objects and a shadow cast on the ground. After I offer a solution to this puzzle by identifying which of the objects is causally responsible for the shadow, I argue that this case poses a counterexample to ...

Support structure tomography using per-pixel signed shadow casting in human manikin 3D printing
Fashion and Textiles, 2022 This study proposes an advanced algorithm for predicting the optimal orientation in human manikin 3D printing. We can print the manikin mesh data on any scale depending on the user’s needs. Once the 3D printing scale was determined, the manikin data were

Casting shadows on holographic reconstruction [PDF]
Physical Review D, 2015 In the context of the AdS/CFT correspondence, we study several holographic probes that relate information about the bulk spacetime to CFT data. The best-known example is the relation between minimal surfaces in the bulk and entanglement entropy of a subregion in the CFT.

HDR Radiance Learning and Shadow Regularization for Satellite NeRF 3D Reconstruction [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesHigh dynamic range (HDR) variations in satellite optical imagery arise from extreme differences in surface reflectance and illumination conditions. Conventional satellite NeRF frameworks are typically trained on tone-mapped or radiometrically enhanced ...

Objects Versus Shadows as Influences on Perceived Object Motion
i-Perception, 2016 The motion trajectory of an object’s cast shadow has been shown to alter the perceived trajectory of a casting object, an effect that holds even if the cast shadow appears unrealistic. This raises the question of whether a cast shadow per se is necessary

Behavioral and Brain Functions, 2010 Background Humans readily perceive whole shapes as intact when some portions of these shapes are occluded by another object. This type of amodal completion has also been widely reported among nonhuman animals and is related to pictorial depth perception.
