Description: 本人根据公式用VC++做出的DCT变换源码，解说清楚。转换矩阵8*8，计算结果与MATLAB计算结果比较，两者几乎一样(相差仅 0.001)，估计是计算误差，经过我的实践证明并不影响使用。-According to the formula I use VC++ source code to the DCT transform, to clarify. Conversion matrix 8* 8, the calculation results compared with the MATLAB calculation results, the two are almost identical (a difference of only 0.001), it is estimated that the calculation error, after I prove that the practice does not affect use.

Description: 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.
