Abstract	In this paper, a 3D video watermarking scheme is proposed for depth image based rendering (DIBR) based multi view video plus depth (MVD) encoding technique. To make the scheme invariant to view synthesis process in DIBR technique, watermark is inserted in a center view which is rendered from left and right views of a 3D video frame. A low pass center view, obtained from the motion compensated temporal filtering over all the frames of a GOP, is used for embedding to reduce the temporal flickering artifacts. To make the scheme invariant to the DIBR process, 2D DT-DWT block coefficients of low-pass center view are used for embedding by exploiting its shift invariance and directional property. A comprehensive set of experiments have been carried out to justify the robustness of the proposed scheme over existing schemes with respect to compression of the 3D-HEVC video codec and synthesis view attack.
