摘要

针对目前抗几何攻击水印算法易在大尺度几何攻击下失效的问题

提出了一种基于几何校正和分块重构的局部区域水印算法

从而提高水印的鲁棒性和提取精度。该算法利用图像不变质心进行几何形变参数的估计

对图像进行几何校正以实现载体的同步; 根据几何攻击对图像视觉质量影响的分析

筛选可嵌入分块; 利用高斯-埃尔米特矩良好的图像重构能力

修改特定矩集

实现水印嵌入

获得含水印图像。为验证算法的抗几何攻击能力

对含水印载体图像遭受旋转、缩放、平移和其他常规性攻击后的性能进行了实验测试。实验结果表明

所提算法可抵抗多种几何攻击及常规图像攻击

相对于其他算法

水印的鲁棒性虽然相差无几但在保持较高视觉不可见性的前提下

嵌入容量有了一定程度的提高。

Abstract

A novel local watermarking algorithm with geometric correction and block reconstruction is proposed to deal with losing effectiveness in resisting large scale geometric attacks. The robustness and extraction precision of watermarking can be improved by this algorithm. Image invariant centroid is extracted to estimate geometric deformation parameters

and then the corresponding geometric correction is performed to achieve the carrier synchronization. The embeddable blocks are selected by analyzing the geometric attack influences to the image visual quality. Taking advantage of the excellent image reconstruction ability of Gaussian-Hermite moments

specially designated block moment collection is modified to embed watermarks.The experiments show that the proposed algorithm with good visual invisibility enables to resist various geometric attacks and common image processing impacts.
