Watermarking of 3D Polygonal Meshes Based on Feature Points

摘要：

In this paper, we propose a novel 3D watermarking scheme based on feature points. We propose an automatic selection of intrinsic feature points that are robust against surface remeshing and simplification. They are detected in the high variation areas. These feature points are then used as centroids for a Voronoi diagram to build a unique partition of the model in several segments. For each patch, we obtain a range image to embedding watermark bits using 2D watermarking algorithm, then modify the relative vertices to get a watermarked 3D mesh model. The experiment results show that the watermark is imperceptible and robust against various attacks.
