兼顾数字水印的稳健性和不可见性要求，提出一种根据图像内容确定嵌入数字水印图像强度的方法。

Considering the requirement of watermarks robustness and imperception, we present a method which can definite the intensity of the image embedded by digital watermark by the content of image.

针对这种情况，本文提出采用基于相位信息的边缘检测方法，克服了基于图像强度信息进行边缘检测的不足，有效地提取了近场光学图像的边缘信息。

So an edge detection method based on phase information is presented, which is more efficiency in detecting the NOSM image edges than the method based on intensity.

数字图像的强度和像素结构具有一些自然的数据模式。

Digital images have natural statistical patterns in the intensity and texture of their pixels.

I think it's the imminence of their fallen-ness that lends this image its incredibly powerful emotional intensity and also, I think, its beauty.

这是它们即将堕落的迫切性,使这幅图像有了无穷的情感强度,和无边的美感。
