“…The results reported in Tables 3 and 4 also compare the data payload, the watermark correlation (corr), and the MRMS measures provided by our method with those provided by two existing watermarking methods (without any robustness consideration): Wang et al method [26] (for Venus, Rabbit, Horse meshes), and Lee et al method [16] (for Horse, Bunny, and Venus meshes). It should be noted that in the case of Wang et al watermarking algorithm, the tested mesh is first remeshed to construct a semi-regular mesh before passing through the wavelet decomposition process.…”

“…It should be noted that in the case of Wang et al watermarking algorithm, the tested mesh is first remeshed to construct a semi-regular mesh before passing through the wavelet decomposition process. The watermarking algorithm presented in [16] consists in modifying the vertices geometry information based on histogram bin shifting. Figure 4 illustrates the maps of the objective distortions between original and watermarked Rabbit mesh using our method and Wang et al watermarking scheme [26].…”

International audienceDigital watermarking can be used as data hiding technique to interleave cover content with auxiliary information before transmitting and storing applications. While image and video watermarking has been widely studied, much less attention has been paid to its application in 3D mesh models. This is principally due to their intrinsic irregular sampling nature. This paper proposes a high-capacity watermarking scheme for the purpose of inserting meta-data into 3D triangle meshes. Our proposal can be applied to meshes with arbitrary topology by using irregular wavelet-based analysis. The watermark is embedded in an appropriate resolution level by quantizing the norms of wavelet coefficient vectors. To ensure robustness to similarity transformation, a robust synchronization (indexing) mechanism is performed on the 3D model after irregular wavelet analysis. Experimental results show that our watermarking framework is robust to common geometric attacks and can provide relatively high data embedding rate whereas keep a relative lower distortion

Abstract:This paper presents MEPP, an open source platform for 3D mesh processing. This platform already contains a large set of processing tools from classical ones (simplification, subdivision, segmentation) to more technical algorithms (compression, watermarking, Boolean operation, perceptual metrics, etc.). Its main objective is to allow a quick start for both users and developers by providing highly detailed tutorials and simple integration mechanisms, through a modular architecture where components are implemented as dynamic plugins.

“…So it is difficult to operate and implement [15]. In 2011, Ho L embedded the watermark by using the vertex information of three-dimensional model surface and the progressive mesh compression to protect the threedimensional detailed model watermark, but the histogram bin shifting technology changes the geometric information of the vortexes [16]. Liu Quan proposed a non-blind watermarking algorithm to construct the spherical coordinate mapping matrix and apply SVD decomposition for constructing a more stable watermarking element to embed the watermark.…”

This paper proposes a holographic blind watermarking algorithm of the three-dimensional mesh model based on QR decomposition. Firstly the three-dimensional model is pre-processed by moving the model center to the coordinate origin and doing PCA analysis. Secondly the model's geometric feature matrix is constructed by using the distance from the three-dimensional mesh model vortex to the model center in the column coordinate system. Then the watermarking information generated by the holographic encrypted technology is embedded into the normalized and blocked model's geometric feature matrix based on QR decomposition. Finally the watermark is embedded into three-dimensional mesh model via inverse QR decomposition and inverse normalization operation. The experimental results indicate that this algorithm can resist translation, rotation, scaling, vertex reordering, noise and cropping attack, which has good robustness. This method can effectively protect the three-dimensional mesh model intellectual property.
