Improved Steganographic Method Preserving Pixel-Value Differencing Histogram with Modulus Function
We herein advance a secure steganographic algorithm that uses a turnover policy and a novel adjusting process. Although the method of Wang et al. uses Pixel-Value Differencing (PVD) and their modulus function provides high capacity and good image quality, the embedding process causes a number of art...
