ABSTRACT
This paper develops the theory for shadow formation and the theory for
recovery of the shape of curved 3-D objects from single aerial images
using shadows. We model curved 3-D objects as generalized cones and
develop methods to obtain the generalized cone parameters of the
object using the shadow. The paper then presents a preliminary
implementation with experimental results and performance evaluation on
real aerial images.
