Generally it demands robustness and imperceptibility.

它一般要求具有稳健性和不可见性。

How to embed enough message on condition of imperceptibility is our object.

如何在满足不可感知性的前提下隐藏尽可能多的信息是追求的目标。

The research on the imperceptibility of information security is developed.

3.对信息隐藏安全性的隐蔽性进行了研究。

By adjusting coefficient difference based on edge detection in wavelet transformation domain,integrative optimization of watermarking imperceptibility and robustness is implemented.

通过基于小波边缘的检测,调节系数差,实现了水印透明性和鲁棒性的综合优化。
