Application of Genetic Algorithm for Embedding of Digital Watermark in Image DCT Domain
Meng Dai · Jisuanji gongcheng · 2008
This paper proposes a novel robust steganalysis system,adopts the genetic algorithm,embed is the watermark information into the DCT domain,and implements an optimized embedding of the watermark information.The genetic algorithm can keep good perceptual transparency,and don′t make distortion of extracted watermark.Experimental results show that the algorithm has the desired properties such as robustness against noise,but insufficiency against smoothing attack and sharping attack operation.
