An intelligent PSO watermarking
Yuh-Rau Wang, Wei‐Hung Lin, Ling Yang · 2010
Meerwald et. al. [2] revealed that the method proposed in [1] exists potential insecurity. This paper proposes an intelligent watermarking by invoking particle swarm optimization (PSO) technique in wavelet domain to overcome the revealed insecurity issue, furthermore resolve the conflict between imperceptibility and robustness of watermarking. Performance analysis shows that the proposed algorithm obviously outperforms the method proposed in [1] which does not use PSO.
