A method of embedding a color digital watermark into a gray level image is proposed.
本文提出一种将彩色数字水印嵌入到灰度级图像中的方法。
A gray level image with rich details is used as a watermark and embedded in vector transform domain, more than scalar transform domain used traditionally such as discrete cosine transform domain, etc.
本文提出了一种新的数字静止图像的水印嵌入算法，该算法将含有丰富细节信息的灰度级图像作为水印，水印嵌入过程不是在传统的标量变换域(如离散余弦变换域等)内进行，而是在矢量变换域实现。
The frequency domain algorithm adopts the common and information - rich gray level image as a watermark, which achieves the collaborative advantages of combining the DWT and DCT.
该频域算法采用更常见的含信息量丰富的灰度图像作为水印，结合离散小波变换和离散余弦变换的共同优点。
