Enhanced Lossless Steganography in 3D H.264 Using Orthogonal Vectors & Limited Distortion Diffusion 🎥

Title ======= Lossless Steganography on Orthogonal Vector for 3D H.264 with Limited Distortion Diffusion Authors ======= Juan Zhao1 and Zhitang Li2, 1Wuhan Polytechnic University, China, 2Huazhong University of Science and Technology, China Abstract ======= In order to improve the undetectability, a lossless algorithm based on orthogonal vectors with limited distortion diffusion for 3D H.264 video is proposed in this paper. Inter-view distortion drift is avoided by embedding data into frames, which do not predict other views. Three conditions and pairs of coefficients are proposed to prevent intra-frame distortion diffusion. Several quantized discrete cosine transform coefficients are chosen from an embeddable luminance 4×4 block to construct a carrier vector, which is modified by an offset vector.
