We used a visual-search method to investigate the role of shadows in the rapid discrimination of scene properties. Targets and distractors were light or dark 2-D crescents …

We have revealed a new role for colour vision in visual scene analysis: colour vision facilitates shadow identification. Shadows are important features of the visual scene …
We show that cast shadows can have a significant influence on the speed of visual search. In particular, we find that search based on the shape of a region is affected when the region …
We investigated the apparent spatial layout of cast shadows up to very wide fields of view. We presented up to 130° wide images in which two 'flat poles' were standing on a green …

Recently, psychologists have turned their attention to the study of cast shadows and demonstrated that the human perceptual system values information from shadows very …
In computer vision for object recognition or autonomous navigation, shadows are a frequent occurrence. However, shadows in an image can make it difficult to partition the image into …

Visual search is slowed for cast shadows lit from above, as compared to the same search items inverted and so not interpreted as shadows (RA Rensink & P. Cavanagh, 2004). The …
How the perception of shadows, studied by vision scientists and visual artists, reveals the inner workings of the visual system. In The Visual World of Shadows, Roberto Casati and …
