Human observers perceive the
three-dimensional structure of objects thanks to a large number of
depth cues. These cues are unequal with respect to their reliability
and to the nature of the information they provide (e.g. depth, surface
orientation, or local shape). We have investigated the ability of
human observers to infer 3D shape from shading, texture, binocular
disparities, motion, and linear perspective. We have also been
interested in the way these various cues interact.
