• In this paper, we propose a novel watermarking scheme for three-dimensional computer graphics (3-D CG) exploiting cross-correlation function in polar coordinate domain. First, we describe polar coordinate transform and its inverse transform. Next, we explain basic procedures for embedding watermarks into a 3-D model and detecting them from a watermarked model. Finally, we perform the computer simulation in order to prove the availability of proposed scheme. The experimental results for some test models show that the watermark information in each model can be detected by our scheme even when the watermarked models are subjected to attack such as random noise addition.
