“…the number of locally embedded bits) in rough areas of the cover mesh. Different roughness measures have been proposed in the literature of mesh watermarking, respectively based on the minimum [YIK03] or total [Bor06] length of the incident edges of a vertex, the dihedral angle between neighbouring facets [CW07] and the variance of the facet normal directions [YPSZ01]. Lavoué [Lav09] devises a roughness measure based on the curvature difference between the input mesh and a carefully smoothed version.…”

Almost all mesh processing procedures cause some more or less visible changes in the appearance of objects represented by polygonal meshes. In many cases, such as mesh watermarking, simplification or lossy compression, the objective is to make the change in appearance negligible, or as small as possible, given some other constraints. Measuring the amount of distortion requires taking into account the final purpose of the data. In many applications, the final consumer of the data is a human observer, and therefore the perceptibility of the introduced appearance change by a human observer should be the criterion that is taken into account when designing and configuring the processing algorithms. In this review, we discuss the existing comparison metrics for static and dynamic (animated) triangle meshes. We describe the concepts used in perception-oriented metrics used for 2D image comparison, and we show how these concepts are employed in existing 3D mesh metrics. We describe the character of subjective data used for evaluation of mesh metrics and provide comparison results identifying the advantages and drawbacks of each method. Finally, we also discuss employing the perception-correlated metrics in perception-oriented mesh processing algorithms.

“…Spatial techniques [1,2] are quite fast and simple to implement, but do not yet provide enough robustness and are rather adapted for blind fragile watermarking or steganography. Spectral algorithms decompose the target 3D object into a spectral-like (or multi-resolution) domain using wavelets [3], multi-resolution decomposition [4,5] or spectral analysis [6,7,8] in order to embed the watermark by modifying kinds of spectral coefficients. Our objective is to propose an efficient watermarking algorithm for subdivision surfaces, which have not been, for the moment, considered in existing 3D techniques.…”

Abstract. This paper presents a robust watermarking scheme for 3D subdivision surfaces. Our proposal is based on a frequency domain decomposition of the subdivision control mesh and on spectral coefficients modulation. The compactness of the cover object (the coarse control mesh) has led us to optimize the trade-off between watermarking redundancy (which insures robustness) and imperceptibility by introducing two contributions: (1) Spectral coefficients are perturbed according to a new modulation scheme analyzing the spectrum shape and (2) the redundancy is optimized by using error correcting codes. Since the watermarked surface can be attacked in a subdivided version, we have introduced a so-called synchronization algorithm to retrieve the control polyhedron, starting from a subdivided, attacked version. Through the experiments, we have demonstrated the high robustness of our scheme against both geometry and connectivity alterations.

“…There are a great number of existing robust watermarking algorithms designed to protect 3-D graphic models [1,2,3], [8], [11,12,13], [16], [19]. Their common purpose is to provide a robust way to protect target contents when attacks are encountered.…”

Abstract. Designing a powerful fragile watermarking technique for authenticating 3-D polygonal meshes is a very difficult task. Yeo and Yeung [17] were first to propose a fragile watermarking method to perform authentication of 3-D polygonal meshes. Although their method can authenticate the integrity of 3-D polygonal meshes, it is unable to distinguish malicious attacks from incidental data processings. In this paper, we propose a new fragile watermarking method which not only is able to detect malicious attacks, but also is immune to incidental data processings. During the process of watermark embedding, mesh parameterization techniques are employed to perturb the coordinates of invalid vertices while cautiously maintaining the appearance of the original model. Since the proposed embedding method is independent of the order of vertices, the hidden watermark is immune to some attacks, such as vertex reordering. In addition, the proposed method can be used to perform region-based tampering detection. The experimental results have shown that the proposed fragile watermarking scheme is indeed powerful.
