Abstract :
This paper proposes a blind and high-capacity watermarking framework for 3D triangle meshes. The basic idea is to use a quantization based approach in the transform domain to embed the secret message. Our proposal can be applied to regular as well as irregular meshes by using irregular wavelet-based analysis. The watermark is inserted in an appropriate resolution level by quantizing the norms of wavelet coefficients vectors. Simulation results show that our watermarking framework is robust to common geometric attacks and can provide relative high data embedding rate whereas keep a relative lower distortion.
