My shadow, myself: cast-body shadows are embodied.
Objects that serve as extensions of the body can produce a sensation of embodiment, feeling as if they are a part of us. We investigated the characteristics that drive an object's embodiment, examining whether cast-body shadows, a purely visual stimulus, are embodied. Tools are represented as an extension of the body when they enable observers to interact with distant targets, perceptually dist...
متن کاملThe multisensory body revealed through its cast shadows
One key issue when conceiving the body as a multisensory object is how the cognitive system integrates visible instances of the self and other bodies with one's own somatosensory processing, to achieve self-recognition and body ownership. Recent research has strongly suggested that shadows cast by our own body have a special status for cognitive processing, directing attention to the body in a ...
متن کاملRendering of Cast Shadows
Appearance-based approaches have the advantage of representing the variability of an object’s appearance due to illumination change without explicit shape modeling. While a substantial amount of research has been performed on the representation of object’s diffuse and specular shading, little attention has been paid to cast shadows which are critical for attaining realism when multiple objects ...
متن کاملThe perception of cast shadows.
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, especially when the shadow is in motion. This find...
متن کاملSelf Shadows and Cast Shadows in Estimating Illumination Distribution
This paper compares two methods for estimating illumination distributions from shadows: methods using self shadows and cast shadows. The cast shadow method provides an effective framework for recovering illuminations in a real scene utilizing variations of image brightnesses inside shadows cast by an occluding object of known shape. The shadow surface is typically the same plane on which the ob...
