The application of genetic algorithm in digital watermark
YE Xiong-fei · Journal of Wuhan Institute of Technology · 2008
An optimal watermark embedding strength is obtained to use the optimization of genetic algorithm,and the watermark is embedded with using DCT.According to the characteristics of genetic algorithm and digital watermark,the methods of selecting fitness function value and ending rule of genetic algorithm are proposed.Experimental results indicate that optimizing the embedding strength based on genetic algorithm can solve the contradiction of robustness and imperceptibility,and implement the optimization embedding of watermark.
