说明： 二值图像数字水印算法的一般方法，然后在此基础上给出了一种基于分块DCT的自参照直流系数盲检测二值水印方法。
(A blind binary image digital watermarking algorithm is proposed in the DCT domain. The algorithm uses the correlativity of the inter-blocks DC components based on blocked DCT with binary image. No original binary image is needed when detecting the watermark. The algorithm is realized with the efficient and practical programming tools MATLAB, The effect of the corresponding parameters is analyzed in detail. )
