This paper investigates the ability of sparse line drawings to depict 3D shape. We perform a
study in which people are shown an image of one of twelve 3D objects depicted with one of …

Three experiments are reported in which observers judged the three-dimensional (3-D)
structures of virtual or real objects defined by various combinations of texture, motion, and …

Depth structure, the third dimension of object shape, is extracted from disparity, motion,
texture, and shading in the optic array. Gradient-selective neurons play a key role in this …

We present a semi-automatic system that converts conventional video shots to stereoscopic
video pairs. The system requires just a few user-scribbles in a sparse set of frames. The …

Humans can obtain an unambiguous perception of depth and 3-dimensionality with 1 eye or
when viewing a pictorial image of a 3-dimensional scene. However, the perception of depth …
