The Capacity Analysis on 3D Watermarking in Parallel-Gaussian Model

A further study on watermarking information-theoretic model based on game theory is presented in this paper. In addition, a parallel Gaussian channels model is set up according to that the assumption of i.i.d. Gaussian noise is reasonable when applied to the 2D geometry images´ AC coefficients of 3D models. The formula of the capacity is given, and the curves for the relationship between the distortion and channel capacity illustrated. Finally, a rudimental search for the solution of the capacity expression constrained by the distortion based on visual threshold is referred in this paper.
