Generalization of the ZZW Embedding Construction for Steganography
Weiming Zhang, Xin Wang · IEEE Transactions on Information Forensics and Security · 2009
We generalize the Zhang, Zhang, and Wang (ZZW) construction to produce larger code families for steganography from existing codes, which can cover the range of relative payloads more densely. We also prove that the expanded code family keeps the similar asymptotic property as the code family produced by the ZZW construction, that is, the codes follow the theoretic upper bound on embedding efficiency as relative payload tends to zero.
