چکیده

This paper presents a generalization of the singular spectrum analysis (SSA) and applies it to the construction of a new robust watermarking method that adds a watermark to a 3D polygonal mesh in the spectral domain. The SSA is originally designed as a tool for analyzing one-dimensional sequence such as time series, and hence it is not suitable for multi-dimensional data. In order to overcome this difficulty, we generalize the basic SSA in such a way that it can be used for the 3D polygonal meshes. Watermarks embedded by this method are resistant to similarity transformations and random noises.

New Spectral Decomposition for 3D Polygonal Meshes and its Application for Watermarking

This paper present a generalization of a data analysis technique called a singular spectrum analysis (SSA). The original SSA is a tool for analyzing one-dimensional data such as time series, whereas our generalization is suitable for multi-dimensional data such as 3D polygonal meshes. One of applications of the proposed generalization are also shown. The application of the generalized SSA is a ...

Watermarking 3D Polygonal Meshes Using the Singular Spectrum Analysis

Watermarking is to embed a structure called a watermark into the target data such as images. The watermark can be used, for example, in order to secure the copyright and detect tampering. This paper presents a new robust watermarking method that adds a watermark into a 3D polygonal mesh in the spectral domain. In this algorithm, a shape of a 3D polygonal model is regarded as a sequence of verti...

Digital Watermarking of Compressed 3D Meshes

This paper presents a robust watermarking algorithm applied to 3D compressed polygonal meshes. Copyright protection of 3D models becomes very important for many applications using public networks. As some recent compression techniques allow very high compression rates, it is of interest to verify that watermarking techniques support this kind of attack. In this paper we present the complete sch...

Impact of MPEG-4 3D mesh coding on watermarking algorithms for polygonal 3D meshes

The MPEG-4 multimedia standard addresses the scene-based composition of audiovisual objects. Natural and synthetic multimedia content can be mixed and transmitted over narrow and broadband communication channels. Synthetic natural hybrid coding (SNHC) within MPEG-4 provides tools for 3D mesh coding (3DMC). We investigate the robustness of two different 3D watermarking algorithms for polygonal m...

Watermarking 3D Polygonal Meshes in the Mesh Spectral Domain

Digital watermarking embeds a structure called watermark into the target data, such as image and 3D polygonal models. The watermark can be used, for example, to enforce copyright and to detect tampering. This paper presents a new robust watermarking method that adds watermark into a 3D polygonal mesh in the mesh’s spectral domain. The algorithm computes spectra of the mesh by using eigenvalue d...
