Spread Spectrum Watermarking for Real Images: Is It Everything

Abstract

In this paper we perform the capacity analysis of knownhost-statitistics watermarking methods based on spread spectrum (SS) under Additive Whight Gaussian noise (AWGN) attack. The reason of our research is based on the paradox that being non-effective in theory SS-based practical watermarking systems outperform known-host-state methods when a commonly… (More)
