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.
