  abstract =	 "An algorithm for automatic construction of a 3D
                  model of an object is presented. The construction is
                  based on a sequence of images of the object taken
                  from different viewpoints. The object's silhouette
                  is the only feature which is extracted from an input
                  image. Images are acquired by rotating the object on
                  a turntable in front of a stationary camera. The
                  algorithm uses an octree representation of the
                  model, and builds this model incrementally, by
                  performing limited processing of all input images
                  for each level of the octree. Beginning from the
                  root node at the level 0 a rough model of the object
                  is obtained quickly and is refined as the processed
                  level of the octree increases. Results of the
                  algorithm developed are presented for both synthetic
                  and real input images.",
