AN EFFECTIVE 3D BLIND WATERMARKING ALGORITHM BASED ON LOCAL ROUGHNESS MEAUREMENT

摘要：

For ensuring robustness and minimizing the distortion of a 3D mesh model, an effective 3D blind watermarking algorithm is proposed. The roughness of a 3D mesh model is iteratively computed by some constraints at first. The constraints consist of a mesh curvature measurement and the angle between adjacent surfaces designed to embed the watermark with the minimal visual quality degradation. The experiment results proved the efficiency of the proposed method.
