We propose a neighborhood-level representation-guided tensor voting model for 3D mesh steganalysis. Specifically, we utilize a tensor voting model to reveal the artifacts caused by embedding data. The normal voting tensor (NVT) operation is performed on original mesh faces and smoothed mesh faces separately. Then, the absolute values of the differences between the eigenvalues of the two tensors (from the original face and the smoothed face) are regarded as features that capture intricate relationships among the vertices. Subsequently, the extracted features are processed with a nonlinear mapping to boost the feature effectiveness.
