Abstract

We propose in this paper, a robust blind watermarking algorithm for 3D mesh models by embedding bits of signature in distributions of vertex norms. Using the Fast Marching Method (FMM), we define regions on the mesh according to a reference location. This robust source location are selected by the salient point detector based on Auto Diffusion Function (ADF). We show that robustness against cropping and other common attacks is achieved. Due to stability of salient points, we can retrieve the watermarked region and extract the watermark. Also, the proposed method has provided a minimal surface distortion in the embedding process.
