Abstract

Security in terms of copyright measurement for digital media distribution is the most challenging task. To maintain the digital right in 3D media, a watermarking scheme is proposed for Multi-view Video plus Depth (MVD) representation to sustain against the view synthesis and RST attack. The Singular Value Decomposition (SVD) is carried out on the left and the right video sequences to find view-invariant coefficients for watermark insertion. Motion compensated Discrete Cosine Transform (DCT) based Temporal Filtering (MCDCT-TF) is used in the temporal direction to make the scheme robust against video compression attack. The 2D Discrete Wavelet Transform (2D-DWT) is processed on the temporally filtered low-pass frames as a pre-processing to get to make the SVD coefficients more connected or say correlated in between the 3D view such that robustness can be achieved against RST and view synthesis with minimum visual degradation. A set of experiments is carried out with different 3D video sequences to justify the robustness of the proposed scheme over the RST attack.
