ABSTRACT
This paper investigates the shape description of the human body based on the discrete cosine transform (DCT). The DCT is able to compress a dense threedimensional (3D) surface into a small vector but preserve shape information truthfully. In order to apply the DCT to a 3D body scan, we segment each scan into six regions and represent them in a cylindrical coordinate system. In this paper we discuss this method and its application to torso shape retrieval.
