Shadow generation from stereo images

Abstract

A novel approach to generating object shadows using two dimensional (2D) information is presented. Existing approaches to shadow generation are generally based on 3D geometry. The proposed method is based on deriving accurate shadows of a 3D object using only stereo images of the object taken from two different viewpoints. The approach can be extended easily to solve more general problems which involve multiple objects as well as multiple planar surfaces on which object shadows are to be cast.
