中文摘要：
根据数字图像离散余弦变换域交流系数的广义高斯分布模型，对盲图像水印技术进行研究，并给出了水印检测器检测性能的理论分析结果。实验验证了图像水印检测理论的有效性以及本文的局部优化检测器性能的优良性。
英文摘要：
By applying generalized Gaussian distribution to statistically model the alternating current coefficient of discrete cosine transform, the technology of the blind image watermark is studied and the performance of the new detector is analyzed. Experimental results verify the theoretical performance analysis and show that the better than that of the linear correlate detector. performance of the local optimum detector isbetter than that of the linear correlate detector.
