Similarity between dirty paper channel and watermarking system • the first noise (dirty paper) s plays the role of the original signal. Abstract dirty paper trellis codes are a form of watermarking with side information these codes have the advantage of being invariant to valuemetric scaling of the cover work. Trellis dirty paper watermarking is an implement of watermarking with side information, which has very good performances but the structure issue remains unclear, and . The writing on dirty paper method, one of the watermark coding techniques used in digital watermarking, is equivalent to a channel coding method in this model the watermark information treated as the signal is coded in favour of the cover vector, which can be treated as the known noise, thus the channel capacity is only dependent on other .
