New wrinkle in dirty paper techniques

Brett A. Bradley, John Stach, Edward J. Delp III, Ping W. Wong
2003 Security and Watermarking of Multimedia Contents V  
Many of the proposed algorithms use quantization to carry out the embedding process.  ...  Although both powerful and simple, recovering the original quantization levels, and hence the embedded data, can be difficult if the image amplitude is modified.  ...  These algorithms, in part, owe their inspiration to a paper by Costa, which considers communication under the presence of noise from two disparate noise sources 1 .  ...
