A robust and blind 3D watermarking algorithm for a triangular mesh is proposed. One of the most important issues in watermarking problems is the robustness, which measures the stability of extracting the watermarks when the watermarked models are attacked. The algorithm in this work is robust to most of the popular attacks. The two key techniques used here are principal component analysis and multi-scale radial basis functions. The experiments indicate that the algorithm is robust to translation, rotation, scaling, noise-adding, smoothing, vertex reordering, mesh cropping, mesh simplifying and remeshing.
