The Visual Hull of Curved Objects


The visual hull is a geometric tool which relates the 3D shape of a concave object to its silhouettes or shadows. This paper develops the theory of the visual hull of objects bounded by smooth curved surfaces. From the basic definitions of visual hull we determine the surfaces which bound the visual hull of such objects. We show that these surfaces are… (More)
