摘要:In this paper, we propose a reversible data hiding technology based on a Vector Quantization (VQ) index table. To improve the hiding capacity, every VQ image has its own corresponding codebook in which the index sequence is reorganized according to the index appearance frequency in the VQ index table. Our proposed scheme is flexible in hiding capacity. That is, the proposed scheme can meet the needs of the user who wants to embed a large amount of secret information in an image and the user who desires a compact final output. The experimental results show that our proposed scheme offers good data hiding capacity and has a good bit rate. Furthermore, to illustrate the performance of our proposed scheme, it was compared with the scheme that Yang and Lin proposed in 2009. Experimental results show that our proposed scheme outperforms the scheme proposed by Yang and Lin. ? 2010 ACM.
