并利用视觉掩蔽效应自适应地选择嵌入强度，使得不可见性和鲁棒性得到很好的折中。

Using HVS to choose the adaptive strength of embedding, it has a better invisibility and robustness.

由于视觉系统具有一些视觉掩蔽效应，因此基于视觉特性的图像隐写算法可以在保证较大的数据嵌入量的同时，使得隐写图像保持良好的视觉效果。

Human visual system has some masking effects, that is the reason why steganography based on the characteristic of HVS has good visual imperceptibility and large payload.

事实上，在第一种情况下存在一些相关的掩蔽效应，相反，第二种情况导致了普通的视觉可视化，为数不多的可预料的数据模型中很少有隐含意义。

In fact, in the first case there are relevant masking effects, instead, the second case leads to common data visualization and rarely hidden meanings from few patterns of data can be expected.
