Optimizing Image Blind Watermarking Using Genetic Algorithm
图像盲水印算法的遗传优化

To improve the practicability of digital watermarking,watermarking imperceptibility and robustness must be ensured. Under the instruction of watermarking robust theory proposed by Cox et al,considering human vision system characteristics fully,a blind digital watermark method based on genetic algorithm is proposed. By adjusting coefficient difference based on edge detection in wavelet transformation domain,integrative optimization of watermarking imperceptibility and robustness is implemented. Experiment show that the method we proposed not only is robust to attacks,but ensures the quality of watermarking-embed image.
