- 由于二维DCT变换是对数字图像矩阵而言的，所以对于RGB位图不能进行DCT变换我在这里先将它转换成灰度图像再把水印嵌入到灰度图像中来进行基于DCT变换的图像水印研究。-As the two-dimensional DCT transform on the digital image matrix is concerned, therefore, for the RGB bitmap should not be DCT Transform I first convert it into gray

- 研究表明，构成K一L变换矩阵的向量也就是ToePhtz矩阵的特征向量。与此同时，离散 余弦变换矩阵逼近于ToePutz矩阵的特征向量矩阵，所以离散余弦变换矩阵与自然图像的 K一L变换矩阵十分相似。经过离散余弦变换后的变换系数块的协方差矩阵Cy非常接近对角 阵，即除了对角线元素以外，其它很多元素都近似为0，并且在左上角集中了主要能量。这 反映了自然图像大部分区域变化不大，亮度突变只占少数，即图像能量以低频成分为主的特 性。通过变换后的量化，舍弃对视觉效果影响较小的次要信息，可达
