Triangle Surface Mesh Watermarking based on a Constrained Optimization Framework

Abstract : A watermarking strategy for triangle surface meshes consists in modifying the vertex positions along the radial directions, in order to adjust the distribution of radial distances and thereby encode the desired payload. To guarantee that watermark embedding does not alter the center of mass, prior work formulated this task as a quadratic programming problem. In this article, we contribute to the generalization of this formulation with: (i) integral reference primitives, (ii) arbitrary relocation directions to alter the vertex positions, and (iii) alternate distortion metrics to minimize the perceptual impact of the embedding process. These variants are benchmarked against a range of attacks and we report both improved robustness performances, in particular for simplification attacks, and improved control over the embedding distortion.
