High-capacity steganographic method based on pixel-value differencing and LSB replacement methods
Journals/International Journals 2010. 2. 24. 15:14In this paper, we propose a high capacity steganographic method using modulus function of pixel-value differencing (PVD) and least significant bit (LSB) replacement methods. The main idea of the proposed method is that secret data can be embedded on the smooth area by LSB substitution and on the edge area by PVD with less distortion to the human visual system and improvement of the embedding capacity. The experimental results show that the proposed method sustains a higher capacity and still a good quality compared with LSB and PVD methods.
