Minimizing additive distortion in steganography using syndrome-trellis codes FREE-DOWNLOAD T Filler, J Judas… – Information Forensics and …, 2010 Abstract—This paper proposes a complete practical method- ology for minimizing additive distortion in steganography with general (non-binary) embedding operation. Let every possible value of every stego element be assigned a scalar expressing the distortion of an embedding
Image Steganography-02
A Modified Side Match Scheme for Image Steganography FREE-DOWNLOAD PY Chen… – 2009 Abstract: In this paper, we proposed an image stegangraphy scheme to further improve the side match method proposed by Chang et al. in 2004. By hiding more information in the edge portions, image quality is improved while maintaining the same embedding capacity. This
