摘要
基于人类视觉系统特性,提出了一种大容量彩色图像静态多重数字水印算法。该算法利用离散小波变换良好的多尺度分析能力,实现了多个彩色水印图像在彩色载体图像中的嵌入及提取。仿真实验结果表明,该算法实现的多重水印具有嵌入信息量大和隐蔽性好的特点,并且对一些常见攻击如叠加高斯噪声、低通滤波、JPEG压缩等有较好的鲁棒性。
A large-capacity static multiple watermarking algorithm based on HAS is proposed. The algorithm by using the well-DWT multi-scale analysis ability,achieves embedment and extraction of multiple color image watermarks in the color vector image. The experimental results show that the multiple watermarks realized by this algorithm have large embedding intensity and strong invisibility,and are robust against some common attacks such as the superposition of Gaussian noise,low pass filtering,and JPEG compression.
