Depth from cast shadows
Together with Pascal Mamassian, David Knill at U. Rochester., and Isabelle Bülthoff and Heinrich Bülthoff at the (Max-Planck Institute, Tubingen, Germany), we have investigated human perception of depth from cast shadows.
See Shadows and depth for some demonstrations.
For 12 minutes worth of assorted shadow demonstrations, you can download the 57Mbyte Shadow Demos quicktime movie.
