中文摘要：

提出了离散余弦变换(DCT)域基于分数低阶统计量(FLOM)水印检测器设计的理论推导和实验证明。DCT域水印检测的传统作法分析与研究实验表明,本文方法更适合数字图像水印处理的实际应用,约束条件更为宽泛,与对照方案相比,水印提取失真率降低了7.6%,且适用对象更具一般性。

英文摘要：

Based on hypothesis of fractional lower order moments(FLOM) on statistical distribution,the paper proposes a new watermark detection method in DCT domain,by the means of fractional lower order statistics estimation.The hypothesis of FLOM is more suitable for practical processing of digital image watermark,theoretical analysis and expeinental results show that proposed method is more efficient than previous study with wider application,and it reduces the distortion ratio by 7.6% compared with traditional met...
