Abstract :
We examine a new masking scheme for three-dimensional mesh watermarking in the spatial domain. The masking factor at each point is defined based an estimate of the average difference between the position of connected vertices to a vertex. We test the proposed watermarking scheme by embedding a random binary sequence and applying different attacks, such as additive random noise, compression by MPEG-4 SNHC, and mesh simplification, which shows that the proposed masking scheme can improve the robustness of the spatial domain watermarking scheme.
