一种健壮透明盲检测的三重嵌入图像水印时域算法

A Robust Transparent and Blind Image Detection Watermarking Spatial Algorithm Based on Treble Embedding

提出了一种基于模数运算的三重嵌入图像水印时域算法。将图像划分为若干节,对每节最大、第二、第三等三个灰度值分别采用模2法嵌入水印。由于采用三重水印嵌入算法,因而有效地提高了健壮性。实验证明,该算法透明性好,健壮性较强,可盲水印检测,能抵抗裁剪、加噪、滤波、转换等攻击。

This paper proposed a robust, transparent and blind image watermarking spatial algorithm based on treble embedding of the modular arithmetic. The image has been divided into several sections, the gray value of the largest, second and third of each section has been embeded watermarking by module 2. Because using the treble embedding watermarking algorithm, therefore it increase in robustness effectively. The result demonstrates that the algorithm is transparent, robust and blind against common image processing manipulations and attacks, such as cutting, noise, filter and conversion etc.
