On the basis of this, watermarking intensity is re-adjusted in watermarking high frequency coefficients according to texture characteristic of watermark image.

在此基础上又结合水印图像的纹理特性对于高频系数水印嵌入强度进行重新调制。

And it USES the texture, frequency and direction of image to choose the embedding position and intensity according to human visual properties.

根据人类的视觉特性，由图像的纹理、频率、方向特征自适应地确定嵌入位置与强度。
