Shape and source from shading
Webb17 dec. 2013 · The perception of shape-from-shading was found here to be influenced by an external light source, even when the light was obstructed and did not directly illuminate a two-dimensional stimulus. The results imply that this effect is robust and not low-level in nature. The perception of shape from shading is not necessarily based on a hard-wired ...

We demonstrate that 3D reconstruction from shadows can even outperform shape-from-shading in certain cases.
