Abstract

Distortion drift, including intra-frame and inter-frame, is a big problem of data hiding in 3D video streams. With the analysis of the coding structure of MVC videos, we propose a new data hiding algorithm without inter-frame and intra-frame distortion drift. Firstly, an ideal that modify the 4×4 QDCT coefficients of the inter-MBs except the rightmost column and the bottom row is proposed, and it can completely prevent intra-frame distortion drift. Then, we point out that hiding data into b4-frames can completely prevent inter-frame distortion drift. The algorithm has lower complexity and a greater embedding capacity than the current algorithms. Experimental results confirm the embedding capacity and complexity superiority of the proposed algorithm while keeping the similar human visual effect. © 2014 Springer International Publishing Switzerland.
