Abstract : With the increasing use of three-dimensional (3-D) models in various practical applications, more and more attention has been paid on the research of digital watermarking techniques for 3-D polygonal meshes. In this thesis, we first provide a comprehensive survey on the state of the art in 3-D mesh watermarking, with an original attack-centric investigation. Then, we make use of the scalar Costa quantization scheme to construct a number of effective blind mesh watermarking schemes. We successfully embed multibit quantization-based blind watermarks in three different mesh domains: the wavelet domain of a semi-regular mesh, and the spatial and spectral domains of a general mesh. The watermarking primitives, which are subject to scalar Costa quantization, are respectively the norms and orientations of the wavelet coefficient vectors, the analytic volume moments and the manifold harmonics spectral amplitudes. Finally, we detail the design and implementation of a robust mesh watermark benchmarking system, which has been made publicly available on-line. This benchmarking system comprises a standard mesh data set, a software tool and two application-oriented evaluation protocols. The robust mesh watermarking schemes proposed in this thesis and a state-of-the-art method are compared within this benchmarking framework. The comparison results demonstrate both the effectiveness of our blind watermarking schemes and the relevance of our benchmarking system.
