Abstract
Cast shadows are an informative cue to the shape of objects. They are partic-
ularly valuable for discovering object's concavities which are not available from
other cues such as occluding boundaries. We propose a new method for recovering
shape from shadows which we call shadow carving. Given a conservative estimate
of the volume occupied by an object, it is possible to identify and carve away re-
gions of this volume that are inconsistent with the observed pattern of shadows.
We prove a theorem that guarantees that when these regions are carved away from
