3D mesh watermarking using salient points

Blind Robust 3D Mesh Watermarking Based on Mesh Saliency and Wavelet Transform for Copyright Protection

“…To further evaluate the performance of the proposed method, we compare it with methods [3,11,12,14,24] in terms of imperceptibility and robustness. It can be seen from Table 13 that the proposed method outperforms the imperceptibility of the schemes [14,24], and [11] in terms of MRMS and MSDM.…”

“…It can be seen from Table 13 that the proposed method outperforms the imperceptibility of the schemes [14,24], and [11] in terms of MRMS and MSDM. In addition, the imperceptibility performance in terms of the HD of the proposed technique is compared to the scheme [12]. Table 13.…”

“…Moreover, our scheme outperforms Wang et al's [3] scheme for MRMS and HD for the three objects Venus, Horse, and Rabbit. Table 15 sketches the imperceptibility comparison with [14] and [12] schemes in terms of the Hausdorff distance for Bunny, Venus, and Horse models. As depicted in Table 15, the proposed technique achieves good results since all the obtained HD values are less than 1.71.…”

“…The importance of a vertex of a region can be different throughout the 3D surfaces for the human eye. To describe this importance, some techniques used the mesh saliency in order to define salient and non-salient regions [10][11][12]. Therefore, to ensure the invisibility requirement of the 3D mesh, the embedding of the watermark should not have a visual impact in the geometry of perceptual important regions.…”

“…Indeed, the watermark is embedded by modifying the mean or the variance of the vertex norm histogram. Recently, Medimegh et al [12] proposed a robust and blind watermarking method for 3D meshes based on auto diffusion function (ADF). The authors extract the salient point using the (ADF), and the mesh is segmented according to these points and the watermark is inserted statistically in each region.…”
